A brief context, this is the backyard of our new house and we are looking to have 24/7 surveillance. As cat crazies we have about 20 cats that are to be housed in the backyard, walls are about 9ft high.
Our objectives are in order of priority:
1. Detect if cats scale the walls or facade of the extension/outhouse.
2. Trying to see where the cats are in the garden
3. Potential intruder (animals or humans) surveillance
I am looking to run 24/7 surveillance recording with a retainment of two weeks at least. Also coupling with a Frigate installation for object detection.
The garden will be lighted with solar powered lamps and the perimeters have solar powered wall lights.
The plan right now is 6 x HikVision 2087s bullets or 2387 domes (Dahua is not easily available in my location).
Would there be a better way to do surveillance of this area? Like 4 x 2087s in the middle, but the tree might create a blind spot.
Also, to cover the whole property, I will need about 15 cameras. Estimated disk usage for 4MP capture 24/7 two weeks is about 18TB according to an online calculator... It's quite hefty, and any ideas for system optimisation?
Thanks in advance!
