Optimised for wireless surveillance links
|
 |
| Viewlock II has been optimised to operate with demanding transmission systems such as RF & microwave video links. It has a very fast "lock-in" time, excellent decoded picture quality and high tolerance to multipath and noise. Indeed, robust in-field performance is a major strength of the Viewlock II video encryption system and its operation is virtually transparent to any link, resulting in little or no effect on range or performance. |

| Typical
Viewlock Application |
|
Highly secure 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 analogue 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. |
