Picture 1:

The left folded dipole array is likely a VHF DB product. The top two antennas on the right side look like UHF Sinclair folded dipole antennas with the bottom one on the right another DB UHF folded dipole. Not sure on model numbers

I'll add some:

2. Hard to tell, too grainy.
3. Looks like possibly a VHF low ground plane antenna. Could be for monitoring CHP or other agencies on low band.
4. Mesh network node.

100% sure on all the antennas in photo 1 that are mounted on the pinwheels(3 sided arms). VHF is a DB. Top two UHF on the right are Sinclair and bottom UHF is a DB

Yep, vhf on top is DB, two top UHF antennas are Sinclair, bottom UHF is DB

The third picture down is a low Vhf monopole

Picture 4 looks like it might be a dual diversity access point for surveillance cameras around the property
