Wireless Mesh Networks for Video Surveillance: Why and How
Available wireless topologies include point-to-point wireless systems, which provide connections between two fixed locations. Low-capacity bridges are typically used for one or two outlying cameras; high-capacity links are ideal for backhaul of other wireless networks.
There are also point-to-multipoint wireless systems, which deliver network connections to multiple remote locations from a central location. These systems may offer a cost effective solution if tall assets (towers or buildings) are available; however, the central “base unit” creates a single point of failure — if this unit becomes inoperative, the whole network goes down.
