Device Guard Switches are switches which will automatically re-power the PoE IP cameras or access point, when the switch detects that they are not working.

In a real application, IP cameras or access points are often located in places which are not easy to reach after installation. As a result, when these devices "crash" or lose power for some reason, it is generally expensive to service them. However, with the use of a device guard switch, the IP cameras or access points can be monitored via their IP or packet status, and will re-power when the crash is detected. This can obviously help reduce the manpower and service costs for the users.

New to the Airlive portfolio is Ethernet switch POE-GSH2004L-370 containing overall 24Gigabit ports, with PoE (Power over Ethernet), designed to meet and exceed the requirements of the 802.3af norm, which requires at least 15W per port, as well as the newer and more demanding norm 802.3at, which among other things requires a minimum of 30W of power for each connected device. POE-GSH2004L-370 has  twenty four  powered PoE ports, each can provide  up to  30W, and the device can deliver up to a maximum 370W of power totally. These ports are protected with an overload protection, should the situation occur where the total power draw exceeds 370W; their power will be gradually switched off according to priority.
