Users of the new TeleObserver MR3041 - the third model in the SilverLine series - will be able to operate four digital network cameras alongside four analogue cameras in the same system. The total recording rate over all eight cameras is 125 pictures per second. The new hybrid recorder can handle high resolution digital video pictures (up to 6 megapixels) and is simple to
install. With only one cable or WLAN required to connect it up, transmitting data within vehicles or between the carriages of a train has never been so easy.

The second new solution being presented at IFSEC also uses the advantages of IP technology for the mobile use of TeleObserver in busses and trains: DResearch is introducing packet data video communication via the internet. Their VPN server provides a secure solution for data transmission between the vehicles and the control centre.

'Video-over-IP' offers significant advantages over analogue point-to-point connection via GSM. With 3G mobile wireless technology a greater bandwidth is available. In addition, the control centre and the vehicles are permanently 'online'. It is therefore obvious at any time which of the mobile systems is available and which not. Dial-up is no longer required. Each availability failure - for example when a monitored bus passes through a tunnel -appears in the log. If the unavailable period exceeds a predetermined duration then an automatic report can be generated. The solution being presented at IFSEC is a DResearch own-development based on open VPN concepts.
