Mobile surveillance

The mobile DVR (digital video recorder) is also being increasingly used by police and the cash-in-transit sector.

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, Valerie Bingham, product manager of Elvey Security Technologies 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 is 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.”

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 four channel audio input and four self-defined, four-sided zones for privacy masking on each camera; multi-information displays and recording such as car licence 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, MultiDVR client, MSS (mobile phone surveillance software) and CMS.

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