Point-to-Point Wireless
Remote camera (optionally PTZ) with no physical network connection to be viewed on a PC. EXAMPLE: A parking lot camera needs to be viewed inside the building. Only power is available at the camera site, no additional cabling.
Solution:
Standard CCTV camera is connected to an encoder, typically an MPEG-4 device for bandwidth efficiency reasons. The encoder digitally compresses the signal into IP, and send it via the wireless transmitter (technically a transceiver) for transmission across the 900 MHz point-to-point wireless connection.
The receiver converts the 900 MHz wireless signal back into IP and sends it via CAT-5 to the recipient, in this case a PC running a standard web browser program (such as Windows Internet Explorer or Netscape) or Bosch VMS software.
Notes:
- Optionally the transmitter/receiver could have connected two switches, and so the connection could be share by multiple encoders.
- Control the frame rate and CIF resolution settings to avoid exceeding the 1.5 Mbps (Megabits per second) bandwidth limitation.
- The most efficient encoder is one of the VIP X or VideoJet X series such as the VideoJet X10 SN, and the corresponding analog decoder for optional viewing on an analog/VGA monitor is the VIP XD.
- For added security consider a pair of transceivers that incorporate secret keys so that nobody can decode the signal even if they intercept it.
