Using the computer to catch criminals

Kalatel's Calibur DVMRe-CT (Triplex) combination digital video multiplexer/recorder provides security guards, managers, administrators and business owners with an e-mail upon an alarm. Without having to physically verify what is happening on their CCTV surveillance system, they can immediately respond to the alarm and take immediate action. No matter where the people are, the DVMRe Triplex sends a message notifying them of the type of alarm and where it is located to an e-mail address on a PC, laptop, PDA, cellphone or pager.

"In addition to automatically displaying images from cameras at the alarm location when an alarm is triggered, the DVMRe Triplex will immediately send an e-mail message, alerting the guard on the other side of the facility on his PDA, the business owner on her cellphone or the general manager on his PC," advises Darren Nicholson, Kalatel Division vice president, marketing.

Alarms can be e-mailed in response to either alarm situations or external alarms. For instance, during set-up, the user can inform the DVMRe Triplex what conditions count as alarms, based on object size and object location within a scene. Then, the surveillance system can employ video motion detection to look through the camera, detect any changes within the scene and recognise them as alarm conditions. Users can additionally set detection sensitivity and false-alarm-rejection levels.

Once the alarm is triggered, the DVMRe Triplex displays images from up to four cameras associated with the alarm area and sends a message to pre-selected e-mail addresses. Hardwired alarms such as door open or window open can also activate such e-mail messages.
