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.
