Micro-View/AudioLock Video and Audio Encryption System



micro-View/Audiolock II is an ultra-compact version of View/Audiolock II, the leading video & audio encryption system for securing law enforcement microwave video surveillance links from interception.

micro-View/Audiolock II consists of a package of only 67 x 54 x 9.5 mm (or a PCB of 50 x 40 mm). It has been designed for highly covert applications, such as body-worn video surveillance, or for integration within video transmission equipment.


Even though it is such a small package, micro-View/Audiolock II retains the all the key features that have made the standard system so successful. These include digital audio encryption, via embedded data within the video, coupled with dynamic line cut and rotate video scrambling. micro-View/Audiolock II is fully compatible with the standard View/Audiolock II units and may be used interchangeably. It is even possible to download secondary keys, together with other configuration data, via the system’s serial port.

micro-View/Audiolock II ensures that even the most covert of surveillance links are safe and sound
