Raptor - for wireless network

Raptor for outdoor operation as access point and wireless client, compliant with 802.11a standard (5 GHz band). It allows point-to-point or point-to-multipoint links. The device is managed by www interface, which permits easy configuration including setting up more advanced parameters. The main use for raptors is for city monitoring systems. The main problems there are caused by extensiveness of the systems - transmission of cameras' images to monitoring center and commands to the cameras (PTZ control).

IP CCTV installations have become the mainstream nowadays. At current stage of IP CCTV there is no problem. At current stage of IP CCTV there is no problem with transmitting data in central parts of cities, using common Internet infrastructure with adequate bandwidth. But the trouble begins when the system should cover some more isolated locations with limited connectivity.

Then the only feasible solution is doing individual wireless network, using WLAN technology.

Both for transmission of video stream and PTZ commands there can be used access points integrated with antennas, powered with use of PoE technology. There may be employed sector antennas, as well as the system itself can be divided into easily manageable sectors.

Practical potential of WLAN systems

• wireless access to local networks in homes, offices, businesses
  
• wireless access to public hot-spots at airports, stations, in coffee shops
  
• point-to-point links (bridging of LANs, telemetry, remote control, remote monitoring)
• delivery of Internet connectivity (in cities and in the country)
• redundancy for wired links (critical connectivity applications)

Wireless CCTV monitoring system

IP cameras win the market share battle due to simple installation and configuration. But the distance between buildings is often too large to use standard UTP/ FTP cable. An excellent solution to such a problem is wireless transmission based on Raptor family of devices. Schemes and more informations:
