Samsung has added two new ONVIF compliant encoders to its 'iPOLiS' product range.

The four channel SPE-400 and sixteen channel rack-mounted SPE-1600R, which houses up to 4 x SPE-400B four channel encoder blades, join the SPE-100 single channel encoder in providing a method of adding analogue cameras to an IP/network based video surveillance system.

All three encoders enable images captured by an analogue camera to be transmitted in real-time across a network at 4-CIF resolution. A multi-streaming feature provides the option of utilising H.264, MPEG-4 or MJPEG compression to minimise bandwidth consumption by simultaneously transmitting images at various frame rates and resolutions to different locations on a network.

In the event of an alarm, the encoders can be programmed to trigger a dome to move to a preset position and, in the case of the SPE-100 and SPE-400, images relating to the alarm can be recorded onto an SD card and an e-mail notification sent.

The SPE-100 has an additional feature in the form of a 'video loop through' which allows captured images to be shared with other devices, such as a display monitor or locally based DVR, prior to being encoded for transmission over a network.

The SPE-100 and SPE-400  offer bi-directional audio, allowing interactive communication between a camera’s location and a control room, whilst both models also allow authorised users to gain access to live images, or images recorded onto a memory card inserted in the encoders’ SD slots, via a web browser.
