Viewlock II

Viewlock II is an advanced video encryption system designed to protect law enforcement video surveillance links from interception. The system offers an excellent level of video security by employing dynamic line cut and rotate video scrambling combined with multiple encryption keys. Highly secure digital audio scrambling is also an option via the system’s Audiolock upgrade.
The Viewlock II video encryption system is compatible with any analogue video link and, with its fast lock-in time and robust performance, is ideal for use with RF links - even in marginal reception conditions. Furthermore, with its small dimensions, rugged construction and ultra-low DC power requirement Viewlock II is perfect for covert installations.
With these outstanding features, together with proven in-field reliability, Viewlock II is now established as the leading video encryption system for the protection of covert video surveillance transmissions by the world’s law enforcement agencies.

Video Scrambling

Viewlock II randomly cuts and rotates each active picture line, offering a very high level of picture concealment and security whilst maintaining link compatibility. Viewlock II even automatically configures itself for 525 line NTSC or 625 line PAL operation and is therefore compatible with almost any transmission system used throughout the world.

Covert Surveillance Installation

Viewlock II’s rugged construction, small dimensions and low DC power requirement make the system ideal for covert installations. Furthermore, its wide operating temperature range and weatherproofing to IP65 specifications, means that permanent outdoor operation is not a problem.

On screen Display OSD

The Viewlock II video encryption system includes an on-screen-display as standard showing information about the status of the link. The OSD shows "Secure" when the link has been successfully encoded and decoded, and "Insecure" when the video has not been scrambled. To aid fault finding and installation Viewlock II also displays additional messages such as "No Link", when there is no video at the input of the decoder, and "No Video" when the encoder’s input is absent.
