Ethernet has a limited cable length between the switch and the camera of 100m (328 ft.). When needed to cover a longer distance, a switch is normally used as a repeater, or optical fiber may be used.To overcome this distance limit, network installers can simply connect an AXIS T8129 PoE Extender in-line with the Cat-5e or Cat-6 cable, and forward the rest to the camera. Dependent on midspan and camera type, the connection in total can be between 200-400 meters (656-1312 ft.).CompatibilityAXIS T8129 PoE Extender is compatible with all Axis network video products supporting PoE, and it is both IEEE 802.3af and IEEE 802.3at compliant. Check in the Set-up tab for information typical connections with Axis network video products.RangeRange depends on the power required, so a 25 watt PTZ dome camera may be located 200 m (656 ft.) away using a single AXIS T8129. Or, the cable length to a regular 5 watt network camera may extend up to 400 m (1312 ft.), by fitting three AXIS T8129 at 100 m (328 ft.) intervals. Check in the Range tab for information about Maximum distances.No additional power supplyAXIS T8129 does not require any additional power supply and the connected network camera is fed by a single PoE switch or midspan. It offers two female Ethernet ports, which are both configured automatically for link speed, duplex and crossover and the full-rate network throughput is maintained.
