10/100 Power Over Ethernet Extender : One RJ45 802.3af PoE in : One RJ45 802.3af PoE out : 15.4 Watt in to 12.4 Watt out : Extension Distance = 100m : Weight = 39g : 7.5×3.5×2.5cm : 400 meter max with 3x extenders
PoE extenders greatly simplify the deployment of IP cameras and other equipment where installation more than 100 meters from the network access switch is required.
Ethernet networking over copper Cat5 and Cat6 cabling is limited to a 328ft (100 meter) maximum distance which is a serious limitation for Video Surveillance Camera deployments as it is not common to have many cameras all within 100 meter radius of your network video recorder (NVR). The problem is prevalent where old cameras that run on high quality RG6 “coax” cabling up to 350m are being replaced with IP cameras. Without the use of PoE Ethernet Extenders if a camera is beyond 100 meters from a switch then multiple distributed switches must be purchased along with the associated wall mount racking to house cable termination patch panels, cable management, UPS’s and power points. Each remote access switch/rack would cost up to $1000.00. To support a camera that is 400 meters away such a setup to extend the Ethernet with switching would be required three times at a cost of three to four thousand dollars.
PoE extenders solve this problem by using a Watt or two of power from the central access switch PoE as their power source to extend the reach of the Ethernet and power acting as a two or five port remote switch. This allows a single Ethernet cable to be extended a second 100 meters or for one cable to be used to power up to four local cameras with no remote power points, racks and local switching required out at the 100 meter point.
By installing multiple PoE Extenders for every 100 meters of cable PoE and Ethernet can be extended for long distances for no bandwidth loss. The limit depends on the number of extenders and their associated power consumption to how much power the IP camera at the end of the run requires. (Remember to calculate camera power requirements for night time when infra red LEDs are active. Basically a camera at night consumes more power with the IR active.)
A neat idea:
If very long distances are required and standard power source(s) are available along the way additional power can be added after the extenders by the use of PoE injectors.
