In terms of installation, the TransVu Express unit's small size means that it can be readily mounted under a seat of a bus or even in the boot of a car. A single connector facilitates easy fitment and removal.

Crucially, TransVu Express has many features commonly only found on larger, more expensive, units such as the ability to automatically download footage and system status on request via wireless communications technologies, and can be accessed remotely via cellular networks (i.e. GPRS HSDPA and 3G). Intelligent power management based on ignition and supply voltage sensors means that the unit will carry on recording for a predefined period after the vehicle's engine has been switched off. Certain models can also provide local monitor output.

Images can be stored on a fixed or removable hard drive in transport applications; a compact flash variant is available for extreme conditions such as mining, oil rigs, heavy duty mechanical equipment and in generally dusty environments.

TransVu is built on the core AD Group NetVu Connected technology, which makes it seamlessly interoperable with all other AD Group servers and DVRs including market leading Dedicated Micros products.

"We are confident that TransVu Express - designed specifically for transport applications - will greatly extend the market opportunities for our TransVu family and bring our industry-leading mobile CCTV solution within reach of a whole new customer base. Already we have received extremely positive feedback from operators who have had an opportunity to trial TransVu Express prior to its official launch at IFSEC 2007, particularly regarding image quality and ease of set up" says Richard Bettley, technical manager, AD Network video.
