I spent about an hour typing out an answer, and it was LONG. Then remembered I’m on ELI5 and deleted it all.
The easiest answer is “it depends on about 100 different factors”. Camera resolution, lensing, form factors, compression, storage, infrastructure to get the video from the camera to the storage (and viewing destination), the equipment to store and view the video, the manufacturer of the equipment and their interoperability with other manufacturers ( or lack thereof), knowledge of the person consulting on all of this….the list goes on and on.
I’ve designed systems that are cheap (inexpensive) and I’ve designed enterprise level systems that cover thousands of locations and hundreds of thousands of cameras. And it all comes down to “it depends”.
The best answer I can provide is it usually comes down to TCO (Total cost of ownership of the system), education, and proper design to meet the needs of the system owner.
The technology exists where we can do everything. Most of the time, the budgets don’t.
I can give answers for and against anything that can be brought up. But in the end, I’d say it takes someone knowledgable and current with what exists to assist.
