That is why we say test it for your field of view. If H265 works, then go for it. Just keep in mind if there are ever any issues, that would be the first thing to change and see if it calms down the VMS system you are using.
Do keep in mind in some scenarios, running VBR could result in the camera not reacting quick enough to get a clean capture for something fast moving. It is why most of us run CBR.
Who cares if it looks like spy facility - maybe it keeps the crime away and if not at least you get good captures.
You are the OP of this thread, so you can talk about deterrence here LOL.
Here are my thoughts on deterrence.
Having a house look like a spy facility is a form of deterrence. The wanna perp will see the cams and simply go to a better less secure home.
Most here find that cameras and motion activated floodlights ends up causing problems with image exposure and are bad for surveillance cameras.. What happens is then the camera is momentarily blinded and you lose the ideal capture when the lights kick on and the camera adjusts from basically no light to a lot of light.
As much as the general public think motion activated lights are a deterrent, they are not. There are
enough videos here showing that perps do not flinch when a floodlight turns on. They avoid homes all lit up, so go with floodlights on all night.
Watch this video someone posted and how the floodlight comes on and they don't even flinch. But then the audio comes on and they don't know which way to run LOL.
