There are many types of PoE switches, ranging from 100M to 1000M to full gigabit, as well as the difference between unmanaged and managed types, and the difference in the number of different ports. If you want to choose a suitable switch, you need to consider comprehensively. . Take a project that requires high-definition monitoring as an example.

Step 1: Choose a Standard PoE Switch

Step 2: Select Fast or Gigabit Switch

In the actual solution, it is necessary to integrate the number of cameras, and select parameters such as camera resolution, bit rate, and frame number. Mainstream monitoring equipment manufacturers such as Hikvision and Dahua provide professional bandwidth calculation tools. Users can use the tools to calculate the required bandwidth and select a suitable PoE switch.

Step 3: Select af or at standard PoE switch

Select according to the monitoring equipment power. For example, if a camera of a well-known brand is used, the power is 12W max. In this case, a switch of the af standard needs to be selected. The power of a high-definition dome camera is 30W max. In this case, it is necessary to use an at-standard switch.

Step 4: Select the number of ports on the switch

According to the number of ports, PoE switches can be divided into 4 ports, 8 ports, 16 ports and 24 ports, etc., which can comprehensively monitor the power, quantity, location of the equipment, switch power supply and price selection.
