IP cameras under the network

IP cameras are the new generation of CCTV cameras. Today, global markets have shown great interest in digital cameras. These cameras, as their name suggests, use fully digital waves to analyze and transmit video and audio data. This means that unlike analog cameras, these cameras digitize the waves from the very beginning. While using digital waves, they are controlled and connected under the network platform. Each camera acts as a device on the network and is connected to the control center by the ip network ID in the form of network patterns and rules.

Dual-purpose cameras

These cameras are actually analog cameras that also have a network output port. Their quality is analog and they can be used as analog cameras or network cameras.
