Why do CCTV cameras always have extremely poor resolution?

I can’t think of a reason why other than the cost but surely it’s worth the potential to solve more crime

You can get bundles with 4 1080p cameras and a 1TB DVR for ~$200.
You can get 4k cameras that cost $100 for just the camera.

The more expensive ones can have a better picture yes, especially in low light, but the big limiting factor for most installations is the amount of storage space, or if you have cloud video storage, your internet connection’s upload speed.

1080p might take 10GB/day per camera, 4k might take 40GB/day per camera. If you have 8 or so cameras, and want to keep a couple months of video stored, that can add up. One 4k camera would eat my whole monthly upload cap by itself.

Though it’s also likely that many of these videos are from very old cameras.

Personally, I spend 100~300 per camera, store full resolution locally, and stream a low resolution to a cloud server.
