Hello
I need to design a feasible and economical video monitoring & recording system with 7 fixed and 3 PTZ cameras on a partly developed housing estate, area about 3km wide & 5km long. The objective is to save money by replacing a number of watchmen hired for security. Only traffic and any suspicious activity in coverage area is to be monitored, not houses. The camera points are to be scattered mostly at road (already built) dead ends (near boundary of estate) and control room is built at the entrance. The distances range between 50m (entrance monitoring) to 4000m (last edge).
My biggest concern is the right selection of transmission media. My first thought was to lay optic fiber along the roads from control room to camera locations. Due to very uneven terrain ups & downs, that seems too expensive (high digging cost). The option with aerial fiber cable may be unsafe for such distances. As there is no internet access, the option left is perhaps wireless. I am not sure about the frequency, but guess it should not be very high to demand for very sharp line-of-sight condition. The uneven terrain will demand very high masts, again uneconomical and unsafe. May be 800 MHz works. Suggestion from you guys will be appreciated to help me settle for the right option. Forgot to mention, a two way audio is also required from control room to all camera points on the same media.
