Bosch beefs up surveillance systems
01 January 2006
The surveillance industry is moving from conventional analogue technology to the more advanced IP-based systems, says Bosch Security Systems, a global leader in the field of surveillance.
Bosch specialises in offering products and solutions for PA (public address) systems and voice evacuation, fire and intrusion, besides conference and interpretation systems.
The Germany-headquartered firm offers end-to-end solutions starting from simple analogue to large IP-based systems that meet the complex requirements of large clients such as airports, malls and convention halls.
“Video surveillance has become indispensable for commercial, residential or institutional establishments – whether large or small,” says a spokesman for the company. “Clear observation and accurate monitoring are essential to keep an eye on your business. Bosch is a one-stop shop with affordable and flexible solutions for all requirements.”
Bosch Security Systems is a long-established expert in the field of surveillance with a focus on quality. From the simplest to the most complex video surveillance system, the company offers a complete line of video cameras, AutoDomes, monitors, VCRs, digital recorders, multiplexers, microprocessor control switcher/controller systems, transmission systems, and other related surveillance equipment, supported with exceptional technical service.
Among its systems are integrated IP high- resolution D/N (day/night) cameras (with 540TVL in colour), which give the client the best of both worlds, as compared to webcam technology for surveillance applications.
“With the surveillance industry having actively commenced the migration from the conventional analogue technology to the more advanced IP-based systems, the sector is currently in the interim stage where phased migration into the digital/IP world is in progress,” the spokesman adds.
Elaborating on network-based technology, he continues: “This technology obviously depends on bandwidth and storage capacity and is influenced by several factors such as compression technology (MPEG* 4 being the most common technology in surveillance) resolution (D1, 4 CIF, 2 CIF**, CIF) and how busy the scene itself is.
“Options also include decentralised recording at distributed locations as well as centralised recording. Recording can be carried out in any part of the network with multiple-access from authorised monitoring workstations.
IP encoders (single/multi channel) are currently available with built-in hard disk and dual streaming technology that allows local storage as well as simultaneous streaming into a central storage server.
“In the event of breakdown of the network, the local storage encoders retain the recording and download the missing section to the central storage server, upon network restoration- automatic network replenishment,” he points out.
Another recent innovation in the field is virtual matrix switchers, which allow any camera to be hooked on to the network as compared to the conventional systems where all cameras had to be physically wired to the analogue matrix. This virtual matrix allows operators connected to the network to be able to view, control, record and view recorded image from their workstations.
There are many significant advantages of moving the CCTV (closed circuit television) into the IP world including expansion, flexibility, reduced wiring, recording flexibility, multiple viewers, automatic off site archiving, video content analyses etc.” he points out.
