Power over Ethernet or PoE extenders are devices used to extend the connection between two PoE-capable devices like a network video recorder and internet protocol camera. This list also includes Power over Coaxial extenders, which benefit analog-based security camera systems. These devices are installed between correlating cables and generally have a design that can be secured to a surface. However, while extenders can be placed multiple times, the signal strength and power will be limited to specific parameters. Typical acceptable quality through RG-59U coaxial cables, for example, has a limit of around 700 feet.
Vivotek, Axis, ACTi, Altronix, Geovision, and Oculur have manufactured extenders available through A1 Security Cameras.
How far can a PoE Extender work?
It is never recommended that PoC be used over long distances. Power over Ethernet extenders is limited to around 2000 feet in maximum length between an applicable device and a switch or recorder. However, whether any distance is reliable is dependent on the output of power.
How does power over coax work?
Power over coaxial works by transporting both the analog signal and electrical charge through the same wire. At the same time, the charge is monitored by the resistor while being appropriately separated from the video signal. Whereas initially, adapter devices were required at both ends of the wire, most Coax over Power capable cables feature a coil and capacitor to dampen the direct current.
What is better PoE or PoC?
For quality, Power over Ethernet is much better due to being related to more modern forms of security cameras and recording devices. However, Power over Coaxial can transmit data and power over longer distances. In addition, newer devices related to both have emergency shutoff capabilities.
Network extensions are communications devices that are deployed along a network to share, extend, or gain access to the network topology. Cable distances up to 1 mile can be achieved by deploying quickly by connecting to a network expander, coax or UTP cables.
