How do you know how many APs and IPCs a PoE power switch can use?

For example, a four-port 100M PoE power switch has a maximum PoE output power of 65W. How many IPCs with a maximum power of 8W can be connected?

The maximum output power of the POE/maximum consumption of the camera is the maximum supported number, but the actual output is generally set to 70% of the maximum power due to the loss of the network cable and transmission distance. That is 65Wx0.7/8W, which is equal to 5.7, because there are only 4 POE power ports, so only 4 are supported, and the others are similar.

The loss on the network cable is mainly the current * the resistance of the network cable. Therefore, the worse the quality of the network cable, the greater the loss. Therefore, this model we made uses 52V output to increase the voltage and reduce the current transmitted on the network cable to reduce the loss. At the same time, it can support More powered devices. It can support long-distance transmission and power supply of 250 meters and solve the monitoring wiring. Some high-cost wiring such as extenders and optical fibers need to be deployed over 100 meters.

Question: How to choose a PoE switch for security monitoring and wireless coverage?

There are many types of PoE switches, from 100M to Gigabit, and then to full Gigabit. There are also differences between non-network management and network management, and the number of different ports. If you want to choose a suitable switch, you need to consider comprehensively. . Take the project that requires high-definition monitoring as an example. In addition, quality and after-sales service are also very important. TB-VIEW has been committed to providing stable quality and excellent service for many years and has been recognized by customers from all over the world.

Step 1: Choose a standard PoE switch

Step 2: Choose a 100M or Gigabit switch

In the actual scheme, the number of integrated cameras, camera resolution, bit rate, frame number and other parameters need to be selected.

Step 3: Choose af or at standard PoE switch

Choose according to the power of monitoring equipment. For example, the camera used has a power of 12W max. In this case, an af standard switch is required. The power of a high-definition dome camera is 30W max. In this case, an at-standard switch is required.

Step 4: Select the number of ports on the switch

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