How to deploy DTV surveillance cameras?
Star topology
In star topology, the deployment of DTV cameras is exactly the same as the original structure of CCTV. The mapping between DTV cameras and a DTV DVR is one-to-one, as shown below.
Daisy-chain
In daisy chain, multiple channels of DTV camera videos are transmitted on a single coaxial cable, similar to the deployment of cable TV system. The mapping between DTV cameras and a DTV DVR is many-to-one. The daisy-chain topology is especially suitable for surveillance deployments at perimeter areas such as large campus, hospitals, parking lots, construction sites, military bases, or important infrastructures.
