The D1 dual stream network video server is used to integrate analogue cameras in digital networks, regardless of the model. Thanks to effective H.264 compression, the server streams camera recordings at high performance, in full D1 resolution and in real time. The server is equipped with a PoE function for flexible and simple installation without an extra power supply - only an IP cable is required for power and data transmission. Apart from this, the video server is characterised by a variety of intelligent functions. Many safety functions can be realised using the audio/alarm input and output. An SD card can be installed, resulting in additional data security in the event of system failure.
