Deterrent and evidence provider, CCTV (closed circuit television) is one of the modern world’s most successful crime fighting tools.


From banks and malls to offices, roads and residences, there’s a wide and growing presence of CCTV throughout the world.  What’s more, it’s no longer confined to static locations, much to the chagrin of the criminally inclined, says Valerie Bingham, product manager of Elvey Security Technologies.


“Major advances in the industry over the last four years have resulted in the deployment of CCTV in mobile locations.  The result is that vehicles can now enjoy the security of real-time, remote surveillance technology, which until relatively recently was limited to buildings,” says Ms Bingham.  “It’s been particularly well received by South Africa’s transport industry, which has long struggled with shrinkage and dishonest drivers.”


The mobile DVR (digital video recorder) is also being increasingly utilized by police and the cash-in-transit sector.  “Owing to its ability to transmit live video feeds back to their stations, it’s regarded as a lifeline by officers who take comfort in knowing that their superiors have the same perspective on potential danger as they do,” she says.  “This real time link to headquarters can be enhanced by special management software which allows users to monitor all equipped vehicles at once.  In the event of an accident or emergency, backup or emergency services can then be immediately notified and dispatched.”


Corruption, long a source of great embarrassment to South Africa, also stands to be dealt a crippling blow with mobile DVR technology.  She explains: “The media is constantly exposing corruption, not least of all in the Department of Transport, where the spotlight has fallen on inspectors soliciting cash bribes in return for issuing drivers’ licenses.  This technology can root them out and, in so doing, play an important role in safeguarding innocent road users from illegal drivers.”


Welcoming the arrival of Dahua’s new Mobile DVR in South Africa, which follows on the successful deployment of the technology in the USA and other countries, Ms Bingham says it has raised the bar in the industry.


“Unlike most DVR systems, Dahua’s mobile unit has been specifically designed to withstand severe shock and vibration and can therefore be directly deployed in challenging, out-of-plant or on-road environments.  It’s perfect for small to medium applications such as buses, trains, taxis and cash-in-transit vehicles, where it will record up to 30 frames per second, using H.264 video compression technology,” she explains. 


Operating on a range of 8 to 36 volts, which is suitable for vehicles of all sizes, and equipped with air connector industrial converters for audio and video inputs, it offers a previously unmatched level of shock and water proofing. 


Additional features include 4 channel audio input and 4 self-defined, four-sided zones for privacy masking on each camera; multi-information displays and recording such as car license plate number, time, GPS, speed and station information; and multi-interface connections such as USB 2.0, Ethernet ports, RS232 and RS485 ports, VGA, alarm in and out, together with a built-in web server, Multi-DVR client, MSS (mobile phone surveillance software) and CMS.


Programmable to record continuously or on motion or event, the recorded video has a embedded watermark to prevent tampering, thereby ensuring complete data integrity.


Data back-up can be done in multiple ways: through the pluggable hard drive case, via USB flash drive, USB hard drive, USB CD/DVD writer, SD card or network downloads.
