The HYDRA system is a rugged multi-channel video acquisition and network video server / streamer system. The HYDRA unit can capture, encode and stream up to 12 channels of video and a single channel of audio over an Ethernet LAN using a variety of compression levels and streaming rates.

The system is designed for video surveillance in harsh environments and is suitable for use in both static and vehicle installations.

The HYDRA system produces an industry standard MPEG-4 video plus audio stream using a standard RTP/RTSP IP stream. The HYDRA can be customized with additional application software if required for specialist installations.

The HYDRA is configured and controlled using a series of HTML web pages which are viewed on any web browser. The control screens enable the user to optimize the compression settings to suit networks with different bandwidth capabilities.

 

HYDRA Configuration / Control Screens

The main System Status page shows which channels have detected a valid video input signal. The Status page also indicates the 'blind video' status - which means that the system has sensed that more than 90% of the screen area is the same color. This can be useful to sense/detect when a camera has been covered (obscured).

The Encoding Options page is used to select all the encoder options to optimize the quality and bandwidth of the encoded video. Each channel can set separately or, the parameters set for all channels.

The Network Options page is used to configure basic network settings. The HYDRA can also be configured with password information, different ways to pick up the time and also a process for updating the core firmware.
