Your source for video surveillance tech tips that will help your business become more efficient!
For some time, coaxial cameras have been reliant on bulky power supplies and the need to install extra cables. This can lead to expensive and cluttered installations. In some cases, installers may find themselves working within budget constraints or set with the task of modernizing an older existing analog system with a coaxial infrastructure. It is in instances like this where SecurityTronix has you covered!
SecurityTronix would like to proudly introduce, Power over Coaxial (PoC) DVRs & Cameras! This technology sends power from the BNC ports on the back DVR to the cameras right through the coaxial cable. This new technology eliminates the need for power to be supplied via a second cable or for the technician to find local power on most runs. This tech bulletin will go into some of the specs and configuration that the PoC devices require.
With reference to PoE standards, the manufacture has introduced AT and AF mode for PoC to distinguish the power level of PoC cameras:
The operating power of an AT camera is around: 7.5W – 9.5W, with AF cameras operating around: 4.8W – 6.8W. These two modes are not related to IEEE 802.3 IP standard.
The operation power may vary depending on camera type/style. For instance, some AT cameras max out around 12W and some AF cameras max out around 6W of power consumption.
See below for a chart that further explains the operation power of AT / AF cameras.

The table below shows the various combinations of AT and AF cameras that a 16-ch PoC device can support:
The allotted transmission distance varies with different cable types and PoC camera models. PoC transmissions also work with video baluns when converting to and from UTP cable.
These recorders can detect the connected PoC cameras automatically, manage the power
consumption via the coaxial communication, and provide power to the cameras via coaxial cable.
The image below displays the channels and PoC status for each channel. It shows the amount/type of PoC cameras added, as well as the amount/type of PoC cameras that can be added.
This concludes the Power over Coaxial walk through guide. We hope you have found this informative and helpful towards your current and future installations.
