“I’ve just spent a fortune on a new alarm system for my premises, yet it’s unable to provide me with video verification of events.”
That’s the lament of business owners throughout South Africa who regard video verification as a critical element of their security.
“People want to be able to monitor the movements and routes of their security guards,” says Zane Greeff, Technical Director for Elvey Security Technologies. “They also want to be able to view events to ascertain if the alarm signal they’ve just received is a crime in progress or a false alarm.”
The answer to this need for real-time event viewing lies with video verification, which allows people to receive video clips via email or messages via cell phone. It also “significantly” reduces the high incidence of false alarms brought about by existing alarm systems, he notes. “Conventional security alarm systems in conjunction with CCTV (closed circuit television) have been widely deployed for years throughout the country’s major metropolitan areas where crime is a major concern. With the advent of video verification, this is now changing.”
One of Greeff’s personal favourite products is the RSI Piggyback, a video verification system that can be seamlessly added on to existing alarm systems. “What makes this system particularly valuable to users is that they can decide which areas are most vulnerable to criminals and therefore require video verification. These could include stock rooms, rooms with safes or outside areas. Up to twenty-four wireless cameras can be connected to the RSI system which is completely self-sustaining and boasts a battery life of up to five years.”
He continues: “The RSI Piggyback cameras, which are equipped with integrated night vision, are designed to take 10-second video clips when the motion sensor is triggered. These are then sent as AES (Advanced Encryption Standard) signals over a secured cellular network to a monitoring station, cell phone or email address. This allows users to receive swift video verification, which in turn makes it possible to respond to an incident more quickly.”
While those at the monitoring station will immediately see what is happening and dispatch the police or armed response to the site, Greeff says that because the system makes use of AES encrypted wireless technology, the signal is assured of optimum integrity and security.
Greeff is impressed by the unit’s multitude of features, from its fully waterproof, anti-tamper camera which boasts CMOS (complementary metal oxide semiconductor) black and white sensors, 85 degree wide-angle lens and 320 x 240 pixel video resolution to its two infrared LEDs, which provide night illumination up to 12 metres. “The system, through its PIR (passive infrared) ability to detect movement, is able to activate the sophisticated Fresnel lens to begin recording in less than 100 milliseconds,” he adds. “It’s the ultimate solution for business owners who want to see what’s happening on their premises, no matter where they are or what time it is.”
