Frequently Asked Question
1. What kind wire use for PoE series transceiver
We recommend use 4 pair Unshielded Twisted-Pair cable, category 3 or higher, 16-24AWG, multi-pair (6 pair or more)twisted pair is ok. If
use STP (shield twisted pair) cable, the modular plugs need to use shielded too, make sure STP shielded and modular plugs shielded connect
together. When need prolong UTP, you can use special RJ45 connect box or jointing to make connection, if in out door use, please protection
against the tide.
2. Why no interference in PoE PVD transceiver when transmitting power via UTP
PoE PVD transceiver power's working mode are based on IEEE802.3AF/AT. And this standard widely used in IPphone, IPcam, and other
Ethernet devices. No interference caused even transmitting power under 1000Mbps Ethernet. PoE PVD transceiver use safe voltage
(DC36V); the transmitter, receiver and remote powered device are at same power ground, so no maladjustment to ground voltage position,
and the signal quality will be better.
3. How can I do when remote camera power over PoE transmit power
Normal CCD camera power is 12V/0.15-0.08A, 56pcs LED IR camera power is 12V/0.5-0.4A.PoE PVD transceiver can supply most camera.
If special camera power over, please use Highpower PoE PVD transceiver, if power over PoE in 50% range, can select 2pair-3pair module,
this module converting 1pair data wire into power wire, can increase 50% standard PoE transmit power.
4. Why PoE PVD transceiver use AC24-28V/DC30-38V input voltage, whether increase the costs
For the UTP is 24AWG wire, and loop DCR 19Ω/100m,so if want to transmit larger power to remote area, it must increase the voltage to
