I have a very difficult site - a public area running up the side of the property with potential access from the side as well as the front, made worse by the fact there are accessible roofs roof providing access to windows at the side and back at an easily accessible height for entry.
So I potentially have to cover - front, drive x 2 (1 in each direction to stop someone coming in under the camera and disabling it or accessing a door out of view under it), 2nd floor side and public area, rear.
You could use the same approach i intend to take: sensors
I will use these 2 ptz for keeping eye on back garden. That is basically U shape so 3 sides.
In normal mode, both watch the back side (no visability of the sides) there is line crossing sensor for the side fences. When someone climbs the fence, ptz will be triggered and turned to that direction.
This will perhaps never happen.. And even with my ebay bought sensors (3 systems for like €135) power supply ( €20 ) and some poles to mount them on (€150) and tubes underground to the poles (€50) and than wires for power supply and alerts (€50) i would be equal in cost with more cameras i guess. 285€ for this camera and like 70 for corner mount and wire box and than like €400 for the sensors it comes down to €1200 or so. (Including tubes in the house for like 100€ each)
Each turret is like €150, so could have installed 5 or so (5 tubes in wall is killing cost here)
So had to choose between these 2 options basically.
With the sensors i can point both ptz to the side and one takes long side along the house, and the other takes the last 6 meters it has visibility off. Will have turrets at the entry doors, so they would have to go there to get inside.
