Transmit data & power up to 800m over network cable with extended Power over Ethernet ( ePoE )
Wired camera surveillance systems tend to use either cat5/6 cable or coaxial cable to connect cameras to a recorder. Providing power to the remote camera may be via a external power connection (separate cable) or over the same cable carrying data. Having a single cable carrying power and data simplifies installation and operation and reduces costs. The longer the distance that power and data can be reliably carried, the lower the cost of installing and operating that system.
Power over Ethernet (PoE) greatly simplifies surveillance and intercom systems by providing power and data over a single cable. Typically PoE is limited to a maximum distance of 100m over cat5/6 cables. Coaxial cable systems are capable of longer distances but typically do not carry power over the coaxial cable.
VIP Vision™ have released a new range of cameras and NVRs that utilise ePoE to increase cat5/6 cable lengths up to 800 meters which is a substantial improvement on the standard 100m. This removes the need for power over Ethernet extension devices which also have their own power supplies and subsequent installation costs. Removing additional equipment increases reliability of the system by removing potential failure points in the network. A camera and NVR with ePoE can now be 800 meters apart with no loss of performance. Note that some cameras such as PTZ that have higher power requirements are limited to 300m as per the diagram.
The same technology can also be over coaxial cable to greatly extend the cable lengths up to 100 meters over the coax. Note that this is using coaxial cable to carry power and data for conversion back to cat5/6 at each end and not for extending coaxial cable networks. See below
Using a VSEOCPAIRV2 Ethernet over Coax Converter Pair, you can transmit power, video and camera data over coaxial cable, running back to an ePoE NVR or switch. The VSEOCPAIRV2 supports power & data transmission over RG59 coaxial cable at a distance of up to 1000m when used in ePoE systems – even further than over UTP.
Please note: This article is only relevant to installations where both the recorder or switch and the camera are all ePoE devices – ePoE is a different protocol to PoE and standard PoE devices will not work with the VSEOCPAIR2 devices. Where you want standard PoE over coax we recommend the VSEOC-ARX and VSEOC-ATX
Save time and money on your installations by repurposing existing coaxial cabling infrastructure for your long range PoE systems.
We have a range of NVR and cameras that support ePoE. Please search ePoE on our search page to see our range.
In Summary: Long cable runs are no longer a problem with the new ePoE range of cameras and recorders. Lower cost, more reliable, and simpler deployment make ePoE compatible systems the obvious choice in cctv networks.
