What device is typically used to connect IP cameras to the CCTV network and internet?

The PoE switch is crucial in connecting IP cameras to the CCTV network and internet because it provides both data connectivity and power over a single Ethernet cable. This feature simplifies installation by eliminating the need for separate power sources for the cameras. Using Power over Ethernet (PoE) technology means that the cameras can receive power and transmit data simultaneously through the same cable, which is particularly advantageous in installations where power outlets may be scarce or difficult to access.

While an Ethernet cable is essential for data transmission, it does not inherently provide power to the cameras. A router is responsible for connecting different networks, allowing for communication between the IP cameras and the internet, but it does not provide power directly to the cameras. A modem connects the local network to the internet but, like the router, does not provide power to the devices on the network. Therefore, the PoE switch is specifically designed to efficiently facilitate both aspects necessary for IP camera operation in a CCTV system.
