High-definition digital recorders

September 2001 Surveillance

PC Open's Open-Eye high-definition digital recorders (HDDRs) leverage the company's DEEP (DEnsity Exchange Protocol) proprietary compression algorithm, which provides realtime recording and viewing of 640 x 480 pixel video images.

"Our revolutionary DEEP compression technique combines the benefits of JPEG compression and Wavelet technology so that HDDR users can quickly recognise even the smallest of details," explains PC Open President Rick Sheppard. "Upon being compressed by our HDDR, images can be stored in an efficient digital file format on a hard disk for later viewing, copying, archiving or remote access via a DSL, cable modem, LAN, WAN, dial-up connection or the Internet."

Because of the DEEP compression technology, images require little storage space and can be accessed in seconds by searching according to time, date or alarm activity. Video clips are digitally watermarked to prevent tampering.

Upon alarm or motion detection, digital control outputs can be programmed to complete a wide variety of functions from initiating distress calls to a central monitoring station to dialling pagers, turning on lights or activating sirens. Multiple motion detection zones can be defined within the viewable area of each camera. If a circuit or contact is broken, the digital control inputs also allow the system to index segments of video.

Three models are available in 16, 8 and 4-channel versions.
