Industrial switches are made for outdoor cabinets, poles, factories and rooftops. They have no fan, a strong metal housing, and work from -40 °C to 75 °C (-40 °F to 167 °F), where a normal office switch can fail in a Pakistani summer. Use one in a field cabinet near the cameras and link it back to the control room.

Hi-PoE (IEEE 802.3bt) sends much more power on one network cable than normal PoE: up to 90 W on a port of this switch, compared with 30 W for PoE+. Use it for PTZ cameras, cameras with heaters or strong IR, and other high-power devices, so you do not need a separate power supply at the camera. The total PoE budget of the switch still applies.

Two limits apply: the number of PoE ports, and the total PoE budget in watts. Add up the maximum power of each camera from its datasheet and keep about 20% spare. Example: 16 cameras at 6 W each need 96 W, plus 20% is about 115 W, so a switch with a 125 W budget or more is right. A PoE port (802.3af) gives up to 15.4 W and a PoE+ port (802.3at) up to 30 W. PTZ cameras and cameras with heaters, strong IR or strobe lights need PoE+ or Hi-PoE (802.3bt). Not sure? Send us your camera list and we size it for you.

SFP and SFP+ ports take a small plug-in fiber module, sold separately. Use them to link the switch to the NVR room or main switch when the distance is over 100 m (330 ft), or between buildings. Fiber carries no electricity, so it also stops surges travelling between buildings. Choose single-mode or multi-mode modules to match your fiber cable, and use a matching pair of modules at the two ends. Ask us for the right modules and cable.
