Private security footage is nothing new to criminal investigations, but two factors are rapidly changing the landscape: huge growth in the number of devices with cameras, and the fact that footage usually lands in a cloud server, rather than on a tape.
When a third party maintains the footage on the cloud, it gives police the ability to seek the images directly from the storage company, rather than from the resident or business owner who controls the recording device. In 2022, the Ring security company, owned by Amazon, admitted that it had provided audio and video from customer doorbells to police without user consent at least 11 times. The company cited “exigent circumstances.”
You can also use proprietary cameras but put them on a separate network segment or otherwise restrict their access so they can’t get out of your local network.
Not ideal to use proprietary cameras at all, but if you are doing then that’s the way to do it.
yeah, if you can’t find FOSS cameras, I’d recommend getting a good old CCTV connected to a device that does not have internet access.
