Coax for Analog Cameras

What you need to know about coax cables!

Coax cables can look the same but are they?   Heck NO! This subject can be a bit confusing but it is very important when installing an analog type CCTV system. Coax (short for coaxial) cable consists of an outer jacket, a braided bare wire shield under than, then a plastic insulator (called the dielectric) and finally, one bare center conductor.

The most common cable type used for CCTV is RG-59/U. But to start with the confusion, there are many types of RG-59/U. One is correct and the rest will not work properly. So how do you know which is the right kind? Strip off a piece of the outer jacket and look at the braided shield.   The correct cable will have a very tightly woven braided shield made with copper. It will have the color of a shiny penny. If you strip off the jacket and you see a loose braid made with aluminum conductors and under that, the dielectric is wrapped with aluminum foil, that is cable TV wire and is the wrong coax cable for CCTV use. At a glance they look the same, but in reality will create havoc with a standard composite baseband video signal.   Because CATV (cable TV cable) uses aluminum instead of the vastly more expensive copper material, CATV cable is significantly cheaper. People with think they are getting a bargain until they find out it is the wrong cable ( and the tears begin to flow after realizing that you already installed it in conduit or through the ceiling)!   Don’t make that mistake!   Ask for “RG-59 with a 95% copper braided shield”.

A video signal traveling over the proper RG-59/U coax cable is good for 750’. Will it stop working at 751’?   No, but the whites in the picture will get progressively more gray and your picture will lose contrast overall the further you go.

Need to go more than 750’? Then you should use one of the following:

* RG-6 coax (with same shield) – RG-6 is good for 1500’ of linear distance before signal degradation. It has a larger diameter and a larger center conductor (18 gage instead of 22 gage). This cable requires different BNC connectors to fit the larger diameter.

* BALUN transceivers with UTP unshielded twisted pair cable – Often called “poor man’s fiber”, this setup can go 8000’ or more depending on the BALUNs (slang for balanced – unbalanced) used.   More on this topic later.

* Fiber Optics – great for large distances (miles) depending on the type of fiber and the transceivers used.   Expensive but worth it.

Siamese Cable is a great invention and consists of (1) RG-59/U and (2) 18 gage conductors to carry the power for the camera in the same assembly.   This is very convenient for the person doing the installation and is highly recommended. Buy bulk Siamese in 500’ and 1000’ spools and cut your cable to the length as needed. Putting the connectors on the end is not as hard as you may think. We give you specific instructions on how to do this properly. No special crimp tools are required if you use our “twist on” BNC connectors.

Other types of cables available:

Smaller diameter coax and Siamese cables are hit or miss. These cables are more flexible, thinner and often come with factory installed BNC connectors at each end. Will you see a picture – yes. But what about the quality? Generally speaking, the thinner the cable, the less distance can be run and the potential for electrical or magnetic interference goes up.   10 years ago, we sold a very thin pre-made Siamese cable that was very problematic. Even short runs of 25 or 50’ would be plagued with all kinds of interference usually in the form of jagged lines or herringbone patterns of lines on the screen. The newer cable is thicker and better overall but statistically, has a one in six chance of picking up interference from a multitude of sources in a typical environment (motors, florescent lights, high frequency sources, radio waves, microwaves, poor grounding etc.). I won’t go as far as to say don’t use it, but use caution and stay away form potential sources of interference. I would hate to say I told you so.

Fake RG-59/U – There has been a flood of RG-59/U cable from China lately that does not contain solid copper shield conductors or a solid center conductor. Instead it is “CCS” – or copper coated steel. Yes, they take cheap steel conductors a fuse a small amount of copper to the surface and call it coax. Don’t buy it no matter how cheap it is – period!

It is surprising that I find quite a few licensed electricians that don’t know any of this. Many so called “installers” keep CATV coax in their truck because it can be 60% or 70% cheaper than the proper coax. Then they wonder why the colors are all funky on the screen and there are multiple fuzzy ghost images creating a poor image quality. Maybe they should read this too!

Low Light Camera Basics

LOW LIGHT CAMERA BASICS

Of course, security is not a sunrise to sunset thing. Although statistically speaking, more breaking and entering crimes occur in the late morning to early afternoon hours, we need our cameras to function well 24-7. Here are a few basics about low light cameras and what to expect from them.

Many years ago, Samsung and Panasonic were the first to develop a “digital nightvision” that became known as “sens-up” as called by the industry from then on. Sens-up, or frame integration, is mostly a useless feature for security use. Essentially, sens-up takes a digital time exposure and combines image frames to yield a brighter picture. Sounds good on paper but as with any time exposure in photography, anything moving in the frame will be terribly blurred. The same thing occurs here. So if you have a mostly dark parking lot and you turn on sens-up, you can make that parking lot look nice and bright but anything moving through the area will be a ghost with no detail or useable detailed information whatsoever.   Don’t rely on sens-up.

INFRARED LIGHT CAMERAS:

Infrared cameras can be very useful in some applications. Infrared cameras are equipped with a number of LEDs that emit light in the infrared spectrum that is visible by a camera sensor that is sensitive to that type of light (not all are). These cameras thus provide their own light source at night and can see in total darkness. There are a few limitations:

  1. First ignore the spec sheet that says a particular camera has an IR range = 125’ for example   That is one big lie! In my 30 plus years of testing these cameras, manufacturers will almost double the true useful range of the IR light on their spec sheets. They all do it. The brand name cameras do it too only slightly less than the off-brand import cameras. So if your camera says the IR range is 100’, don’t expect to see someone lit up like a Christmas tree at that distance.   50 or 60’ is a more realistic distance.
  2. IR light is kinda like the light from a flashlight only you can’t see it. A typical flashlight is a concentrated beam in the center that doesn’t spread out very wide. The same is true with IR light. This is why you generally don’t see IR cameras with wide angle lenses. If you have a IR camera with a Varifocal lens set to the wide setting, during the day you will see a nice wide image. At night, you will see the same wide image but only the center 60% (give or take) will be illuminated by the IR. This is not a reason to avoid an IR cameras but keep this in mind when choosing a location for your camera. Keep the important real estate in the center of the image.
  3. “Smart IR” is a wonderful thing especially if your IR subjects will be frequently close to the camera (like a back or front door, a close in shot of a walkway or hallway etc). What happens is a camera without this feature will crank up the IR output to the max because all it sees is darkness. When a person walk into that dark frame, the camera will seriously over expose the image and you bad guy will look more like a washed out ghost. While this is better than nothing, the “smart IR” feature will solve this problem and yield more properly exposed images even if the person wanders very close to the camera (like doorway cameras). Our  analog Telpix IB-6335MV is equipped with this feature and puts out a great picture even if the person is only 2 or 3 feet from the camera.
  4. Most IR cameras have a red glow at night when you look directly at them. This is normal.

 

DAY/NIGHT CAMERAS:

The lower cost “day/night” cameras (frequently called electronic day/night) are pretty much no better in the black and white night mode then they are in color. This is pretty much a gimmick and really does very little to enhance to cameras viewing ability at night. If this is what your budget can handle, you have nothing to lose. Run with it.

A better choice (and more expensive) is called a “true” or “mechanical ICR” day/night camera. Not to get too technical, but this has a mechanism that adds/removes a filter that allows the camera to see better under low light conditions. Day/night cameras switch over automatically to black and white imaging at night. A true day night camera will be your best choice if you need to see beyond the typical range of an IR camera at night. Use a good low light lens for the best results. A lens with an “f rating” of 1.0 or lower (like.95) is best.

Specs to watch – “minimum illumination” refers to the cameras ability to see in low light. The lower or smaller the number, the better the performance is. This is listed in lux or Lx which is a value of illumination. Ignore any specs relating to sens-up. As I said before, that feature is useless. Here are some guidelines for minimum illumination values from higher to lower:

.2 lux and above (larger) – expect poor performance at night – leave the lights on!

.1 to .05 lux – average. If your scene is really dark, think about adding some lighting to supplement.

.04 lux and below (smaller) – good. Even this camera will not see in a really dark area but this is the best available without infrared.

Which camera is right for you assuming that night viewing is important?   If your critical subject is about 60’ or closer, consider a good IR camera (avoid the cheap junk). If you need to see out beyond this distance, consider a good true day/night camera. With either choice, you may need to add some supplemental lighting to get the most of your nighttime images. Energy efficient bulbs make this viable option now. No camera is perfect under low light conditions but hopefully, this will help you get the most out of your CCTV system at any time of the day or night.

IP Camera Resolution Explained

IP MEGAPIXEL RESOLUTION…… What???

The CCTV market has mostly shifted to IP cameras. The Network camera offerings were pretty lame years ago.   Expensive, complicated and poor performance in low light. Well, most of that has changed. The price is down, resolution is up and the low light performance has gotten better.   So what does all this mean when it comes to picking an IP camera? Lets get an understanding of IP camera resolution and aspect ratio. They go hand in hand.

Resolution – the number of pixels that the image contains and is expressed in a horizontal quantity and a vertical quantity. i.e. 640×480 is an image that is 640 pixels wide and 480 pixels high. A pixel is an individual dot with a color value and brightness controlled by the system.

Aspect ratio – this is the shape of the image or the ratio of the quantity of horizontal pixels to the quantity of vertical pixels. The US TV standard for many years was exclusively 4 to 3 aspect ratio (expressed as 4:3). This image is therefore 4 units wide by 3 units high. Take a VGA resolution image: 640×480. If you divide the 640 by 4 you get 160.   Multiply 160 by 3 and you get 480 thus you can see with some simple math that this is an image with a 4:3 aspect ratio.   Now for some dumb reason, in the past few years, there has been a big shift to the 16:9 ratio. This format is widely used for cinematic theater.   Great for movies, not so much for security in my opinion.

Now lets go over common resolutions and aspect ratios for security cameras.

VGA (Video Graphics Array)

VGA resolution comes from an older computer display format and generally means a camera with an image that is 640 pixels wide by 480 pixels high.   VGA by today’s standards is a low resolution image. Fine for a back door camera where you can get a big close-up of the person entering.   Not sufficient for detailed viewing of larger areas. VGA cameras have all but disappeared.

1.3 Megapixel

1280×1024. This is a resolution widely used for IP cameras a couple of years ago and is now fading for higher resolutions. Most cameras of this type allow you to choose between a 4:3 aspect ratio and a 16:9 ratio in the settings. The 16:9 ratio has a pixel layout of 1280×720 and is also called 720P high definition. If you multiply the two numbers, you will get 1,310,720 total pixels (thus 1.3 megapixel or 1.3MP resolution). You can usually get away with using a quality CCTV lens made for standard analog video on your 1.3MP camera without degrading the image. Don’t use an off-brand junk lens though. Stick with a Tamron, Fujinon, or Computar brand and you will be safe.

2 Megapixel

“Full HD”, 1080P or “High Definition”, is considered to be 1920×1080 pixels (16:9 ratio) in size and has been adopted hook, line and sinker for consumer HD TV for several years now. This resolution is still widely used for a majority of cameras as of this writing.   You have heard the term 1080 or 1080P?   This is where it comes from (not to be confused with 720P, 1280×720, which is not “full HD” – about half the number of pixels). Just about all 2MP cameras can output a smaller size image like those from a 1.3MP camera. But why?   Bigger is more fun. You paid for those pixels, why not use em! Just kidding. Outputting a smaller size image may be advantageous if the shape of the scene you are capturing is better suited with the 4:3 ratio. Thus, less date traffic is put on the network and storage devices. NOTE:   Don’t use a standard lens on your 2MP and 3MP cameras. Use a lens that has sharper optics made for megapixel cameras. You will be wasting your money if you don’t.

3 Megapixel

3MP (2048×1536) is a pure 4:3 ratio and has 1/3 more pixels capturing the video than the high definition format. Wow! I have been joking about “more is better”, but that can also get you into trouble. First is bandwidth (simply put is the amount of data that can flow through a network system without bogging down). A 3MP image frame is about twice as large as that from a 1.3MP camera. That uses up your storage space twice as fast and eats into your available bandwidth and processor power quickly. 3MP cameras are beginning to fade. Get a 3MP lens if you want a box camera, no exceptions.

4 Megapixel

Now we are talking! Twice the pixel count as full HD – 2592×1520 size. As of today, I really think this is the sweet spot. Plenty of pixels for even demanding applications, a reasonable price compared to 4K and a file size that is manageable with most NVRs. My favorite camera as of this writing is the Samsung QNO-7080R. Sharp as a tack and decent low light capability. Still the 16:9 format. If you have the network and NVR capacity. Go with a 4MP and don’t look back. You will be glad you did.

4K

Coming in a roughly 12 megapixels – 4072×3046, this is the highest resolution we have currently available to the everyday security industry.   A couple notes of caution:   First, the price is up there.   Between one and two thousand dollars for a fixed format camera. Yes, the price will come down. Be cautious when pairing 4K cameras with an NVR. Only a few NVRs have the horsepower to be able to handle the recording bandwidth needed for 4K. Read the fine print as other NVRs will limit the recording resolution or the frame rate severely to handle a 4K image size. Currently, the best options for 4K are the XRN series from Samsung or an appropriately equipped Exacqvision system (or similar from ONSSI, Milestone etc.). Now from the practical viewpoint: we compared a 4K camera to a high quality 4 megapixel camera. The difference was somewhat noticeable, but not major. My recommendation is to stick to a good 4 megapixel camera until the price of 4K comes down. But, it’s your money….

 

Monitor size

I am often asked what size monitor to get with my IP based CCTV system.   As you probably gathered, I’m not a big fan of the 16:9 format for security. Watching movies yes. In my opinion after 30 years of doing this, most typical scenes just fit better in a 4:3 ratio frame (i.e. looking down hallways, looking down the outside of a buildings, doorways, parking lots etc). There are lots of 1920×1080 monitors on the market. If you put a 1.3MP image on that monitor, expanding the image to fit will yield about a 30% smaller viewed image than the real estate that is available for you to use. If you set your viewer to fit the horizontal pixel space of the monitor, you will have to scroll to see the top/bottom of the image. Not a deal breaker but awkward nonetheless. I like the 1920×1200 monitors. This is a nice compromise for security use between the 4:3 and the 16:9 ratios. I have several and love them. Generally by the math, 2MP and 4MP cameras fit better on a 16:9 ratio screen and 1.3MP and 3MP cameras fit better on a 4:3 ratio screen if you use the full resolution output. As I said, the 1920×1200 is a nice in-between.

IP over Coax Cable?

IP over Coax Cable – YES!

Many businesses are considering making the transition from an existing Analog CCTV system to IP based surveillance. Mostly for the expand-ability and the higher resolution recording capability. It’s a fact that currently, the cost of the IP cameras and the recording NVR server are still more expensive than other technologies. So we at Pro Security Warehouse are constantly looking for ways to make this transition easier and hopefully, a little cheaper!

Enter the “IP over Coax” transceivers. If you have a traditional CCTV system that you want to upgrade, the part of your old system that you can re-use is the coax cable. This requires the use of a device to transmit TCP-IP over what is essentially a two conductor wire (coax) instead of Ethernet cable which has 8 conductors (4 used). Not necessarily an easy feat. This approach would save the cost of the cable and more importantly, the cost of the labor which is usually the bigger nut. So what venues should consider IP over Coax? Any facility with longer cable runs such as warehouses, industrial or commercial facilities, or even a typical supermarket. Additionally, any application where it would be difficult to replace or run new wire. Full conduits, transits through elevator shafts, and multi-floor penetrations are a few examples of conditions where even for short distances, it may make sense to use this product.

We have searched for the best IP over Coax at the best price. And the winner is… the Altronix eBridge 1CRT and sells for $189 for the set. This kit consists of a primary transmitter and receiver. Although TCP-IP is bi-directional, this set achieves a faster download speed with the units in a particular layout. This is typical for an IP camera configuration where a majority of the data traffic is from the camera to the NVR. The really big news is that the range of this set is up to 1500’ – wow, that is 5 times structured wiring specifications. The size of the units are small enough to fit inside of a typical camera housing or anything larger than a 4”x4” J box. They conveniently run on 24VAC or 12VDC so it’s an easy thing to tap off of the existing camera power.

In our testing, the throughput measured at about 22 mbps, a little less than the 25 mbps listed on the spec sheet. No big deal, that is plenty of bandwidth for several megapixel cameras properly managed. The units are not weatherproof but seem ruggedly built. They come with a Lifetime warranty and are UL listed. What is not to like? These are priced less than most and are designed to operate on RG-59 CCTV coax cable (as opposed to CATV or cable TV coax). This set has not been tested or verified to work on CATV coax (which is identifiable by the aluminum foil covered dielectric and a loose braided aluminum shield). These two cable types are commonly considered the same but are in reality, are totally different and NOT interchangeable.

This is a great tool to consider using when transitioning to an IP system. Is it for everyone, no, but it just may save you some money in the process.

Understanding the HD-SDI format

Understanding HD-SDI technology

HD-SDI or “High Definition – Serial Digital Interface” is a technology wave that started a few years ago and hit the Asian import market by storm.   HD-SDI brings amazingly clear full HD (1920x1080P) resolution pictures with the ease of installation and operation of a traditional CCTV system. In fact, the HD-SDI DVRs look and operate just like your old unit. Although it may look similar, it uses an entirely different type of signal and therefore, the cameras are different. Traditional analog cameras will not work with a HD-SDI DVR. Conversely, HD-SDI cameras will not work with a conventional DVR. Here are the pros and cons to consider when looking at this high def system.

PROS:

  1. Easy to install – the HD-SDI system uses common coax cable. That’s good news if you are replacing and existing system.   You don’t have to install new wire!!!     Well maybe… The HD-SDI is particular about the cable type. If you have RG-59 coax with a 95% copper braided shield, you are in luck. HD-SDI will work for you if your cable runs are about 450 feet or less. You do not even need to change the connectors.   This new system uses BNC connectors just like your old system. Obviously, if this is not a concern with a new install.

If you have the thinner pre-made cables or cable TV coax cable (identifiable by the aluminum foil shield and the silver braid), the signal will be rejected by the DVR. Don’t even try it!

  1. Easy to understand – The DVR looks and programs like any conventional DVR.   Your learning curve is pretty small.   If you want to view images over a network, the same level of networking knowledge is required for the HD-SDI as it is for any other traditional DVR on the market.
  2. Reasonably priced – The current wave of DVRS (such as our Prime XVST-MAGIC-U16M  16 channel DVR) is priced between the lower cost analog CCTV equipment and the higher priced IP camera NVR systems. The price bracket for the cameras are even lower considering the advancing technology. A nice quality outdoor IR camera (such as our XIR-2142FV is priced under $200 ea.).
  3. Beautiful picture for the price – During the day or in locations with good lighting, the picture is stunning. If you have a low light application, be sure to use an IR camera (such as our XIR-2282FV). The infrared will give you a reasonably good picture up to about 80 feet away.   Beyond that (as all IR cameras do) the picture quality will degrade to that of analog video due to the lack of sensitivity of the CMOS chip used in most HD-SDI cameras and the increase in picture noise (typical of import cameras but less of a problem with name brand cameras).

CONS:

  1. Recording speed limitations – The older systems had a maximum recording speed of 7 images per second, per camera at full resolution. Personally, I don’t think this is a problem but some people may. For me, I’d rather have quality than quantity any day. Remember, the faster you run your recorder, the faster it will fill up the hard drive(s) = less storage time.  Processor improvements on new models have mostly solved this issue.
  2. Unproven reliability – HD-SDI is a technology offering on the market by “Asian import companies”. Only what we would call “import (off) brands are manufacturing these. With a brand name such as Panasonic, Samsung, Sony, Pelco or Axis you have more consistent reliability and warranty service.
  3. GUI lacks polish – The GUIs (graphical User Interface) for system programming, network viewing and mobile viewing just aren’t as seamless as those from Exacq, ONSSI, Panasonic etc.   Do they work – yes, but they could be better. They lack some functionality that I feel they should have but all of the basic needs are there. Once this technology takes a stronger hold, we should see improvements in this area.
  4. Cable requirements – As mentioned before, you must use proper coax cable and with it, you have a distance limitation of around 450 feet. Not a problem for most applications but something to be aware of if you have a huge warehouse.

In conclusion, would I give this technology a try? – heck yes.  So far, so good. Yes, it costs a little more than analog but you get full high def imaging.   Leaps and bounds sharper than standard definition. This will make getting those details for the police from the playback video when you need them a reality.

Transitioning from Analog to IP

TRANSITIONING FROM OLD CCTV FORMATS

I get asked this question a lot. “How can you transition from my older analog system to a new HD system without breaking the bank?” This is a typical issue for the retail industry and many others. Usually most of their system is still working to some degree. Maybe you have a few cameras that are out or have bad and worsening pictures. I am going to present 2 ways to make this less painful.

The first method is to purchase one or several video encoders depending on how many cameras that you have. These are available in typically 1, 4, and 16 channel sizes. Axis encoders are probably the best choice out there. You can see them here. A video encoder changes an analog camera signal to a digital stream that can be read by an NVR. Exacq is the best choice for the NVR here since it is compatible with most encoders on the market. Give us a call since Exacq has many different options for NVRs. We can help.

So once you get your camera cables plugged into your new encoder, (you can use your existing coax cable for the time being) and your new NVR is setup, you will be able to record your old cameras. Now keep in mind that the picture quality will be no better at this point but remember this is a process that will allow you to transition slowly without a huge upfront cost. Now it is time to replace any bad cameras with new IP Network high definition cameras. Here are a few of my favorites.

Samsung QNO-7080R Bullet style (best quality)

Samsung SND-L6013R Indoor dome (lowest cost)

Samsung SNV-L6083R Outdoor dome

It is best that you replace the old coax for these cameras with new CAT 6 cables. In many cases, you can use the old coax as a pull string to pull in the new network cable making this process easier. There are a few gadgets that allow you to put network data over old coax but it is an extra cost and just one more thing to break in the future. It is time to do the job right. These replaced cameras will have a great high definition picture! So now, you can take the rest at your own pace and replace the analog cameras as your budget allows. When you have completely finished the changeover, many people sell their encoders on Ebay. They tend to hold their value fairly well and are somewhat in demand. Let us know if you have any questions.

The second method is to replace your existing DVR with a multi-format unit such as the Samsung HD Plus series or the Prime Magic series. The Samsung AHD (Analog High Definition) DVRs are really economically priced and you can utilize your existing coax cables and power supplies. Change out the DVR first. It will accept your old analog cameras. Remember, the picture will be no better at this point but you are on the right path. Then change out your cameras as your budget permits to the new AHD cameras. Once you change the camera, that channel will have a nice clear 1080P image. These cameras are at the very low end of the cost scale for a good reliable brand name such as Samsung.

Which is better? The IP camera system will cost more overall but will allow even higher resolution cameras to be connected in the future. 4 megapixel cameras have double the resolution of HD and you can really see the difference. 4K cameras have even more resolution (12 megapixel) but they are still up there in price. They will come down. The AHD system will be cheaper but there are technical issues at this time that will not allow them to transport 4MP or higher resolutions. If 1080P does the job, then save the cash and go with AHD.

What is ONVIF?

What is ONVIF???

 

Wow – so many acronyms, so little time. I can’t keep track of them all. This one stands for “Open Network Video Interface Form” so what does that mean to me? ONVIF, like many others, was/is a group of industry professionals that got together to decide on standards for future development of the technology with a goal (amongst others)…. to agree on coding formats for IP video cameras. OK that’s a good thing. The IP video equipment manufacturers, were developing the technologies separately as they saw fit (compatibility was avoided to help force you to buy their cameras exclusively).   ONVIF standards provide a common thread to allow some degree of compatibility from one brand of equipment to another. Notice the operative word was SOME!

So what do I need to know about ONVIF? Well for one, if your NVR and IP cameras are two different brands and they are both ONVIF compatible, they should work together. Before ONVIF there wasn’t a snowballs chance in…. (well, you know what) that they would connect. Good progress and getting better every day.   Remember the operative word above? There will be SOME compatibility – not total compatibility.   It is kind of like when you stepped on your remote control for your 6 year old TV and broke it. Couldn’t get an exact replacement so you went to Walmart and bought the “Universal Remote Control”. Life is good again until you discover that only the channel, volume, and a few other buttons worked. That is what ONVIF is like at present. Your NVR will see pictures from cameras and record them but most likely, motion detection recording, audio, alarms, and other higher end functions will not work.

To make things more confusing, there are different “profiles” of ONVIF. This is the natural progression of including more and more of the functions that earlier profiles did not include.

Bottom line – don’t expect to have all of the bells and whistles work in a ONVIF compliant mis-matched system as of now. They will some day. I have seen many times through experience that motion detection recording will not work.   Since this is a popular feature, companies like Exacq, our favorite hardware and software NVR maker, spends lots of time and resources (money) to write drivers for just about every major camera on the market. These drivers allow the higher end features to work properly. Give us a call at (407) 447-1637 and ask us about Exacq products. You will be glad you did.
