Poe switches are widely used, especially network monitoring and wireless coverage, because they can be powered by a network cable, subtract additional cabling, and make construction easier.

In the Network Monitoring project, a monitoring system has a lot of network cameras, and some network cameras with infrared lights, so many friends think that Poe Switch power supply is larger, so the larger the choice. Actually the bigger the better?

The view of these people is, to a certain extent, the right, Poe Switch power supply is really bigger the better. For example, if there are 8 cameras, each power is 20W, if using a rich up to 8 Poe Port ps1082t switch, this switch has a total Poe power of 140W, then the same is for the above 8 cameras power, the total power needs to 8x20=160w, This is more than 140W so no power, need to switch to more powerful Poe switches such as ps1016g. If the above 8 camera head! Rate is less than 15W, such as only 12W, then the ps1082t is fully capable of full power supply.

This shows that Poe switch power supply, the greater the better, especially a lot of cameras with infrared lights, more need power switch, or the camera will appear normal night "strike" situation.

Is that a high-power Poe switch that is always chosen? Also not, need to according to the specific situation, if the camera power is relatively small, and without infrared light or infrared light is less, basically support the AF standard Poe switch can meet the requirements, if the use of high-power Poe switch is wasteful. If the camera power exceeds 15W, or if the power does not exceed 15W but there is a lot of infrared light, it is recommended to select the switch that supports at standard.
