Keeping cameras connected

Network (IP-based) cameras are now in widespread use for video surveillance, teleconferencing, remote monitoring, Web attraction and property showcase applications. However, in the case of installations beyond the edge of the wired LAN, the cost of running new Ethernet cables to these network cameras can be prohibitive.

To address this deployment barrier, AvaLAN Wireless has created a long range non-line-of-sight (NLOS) wireless Ethernet bridge operating in the 902 - 928 MHz frequency band.

Taking advantage of the penetration capabilities of 900 MHz frequencies, the AW900 Ethernet bridge can transmit through 10 internal building walls or a small grove of trees. AvaLAN says field tests show an increase in range and sustained throughput for NLOS applications versus 802.11 systems at 2.4 GHz or 5 GHz.

With 12 non-overlapping 1.54 Mbps channels, AvaLAN radio technology has the capacity to provide a total of 18.5 Mbps of data rate, which can support up to 24 MPEG-4 network cameras.
