I bought this switch to power three Vivotek (one outdoor 8361 and two indoor 8161) security cameras. One 8161 camera is on twenty feet of cable, the 8361 is on 75 feet and the other 8161 is at the end of about 150 feet. The cable is Cat 6, 23 AWG solid conductor with core separator to keep the pairs separated. For a short while, I had the 8361 at the end of 150 feet and it has the IR LEDs and internal heater. It drew somewhere around 7.4 Watts (47.4 Volts at 160mA). Without the LEDs, the 8361 pulls about 3.9 Watts (84mA) while the other two pull about 4.1 Watts (92-94mA), all at 47.4 to 47.5 Volts which makes sense since they're probably on the same Voltage rail inside the switch. In any case, I've never had to reboot the switch for any reason. The PoE power control on each port reliably switches power to a port on and off through the web browser interface control. I use one Gigabit uplink to talk directly to the gigabit my security camera server computer and the second to...Read more
