Either two different systems or two different FOVs.

The cameras don’t look to be the same manufacturer; while normally one can use multiple different camera brands and models in the same system, many integrators tend to keep the same product lines in order to leverage volume purchasing, minimize the numbers of different vendors, minimize inventory, and to make it easier on the technicians.

Often times, there’s a requirement as to exactly how many pixels are required to be on target - compliance or regulatory, legality for enforcement and prosecution, etc. The first could be an overview and the second could be a specific area.

Or, it could be a building security/tenant situation.

Or maybe the last tech was too lazy to take down the old camera and didn’t wasn’t to cut a new ceiling tile, so he installed the new camera next to the defective camera.

Thanks for the explanation, there were 4 other cameras in a room about 3~ meters wide and 7-10 meters long, though it seems like 3 of the cameras were watching down open hallways leading into the room I was in.

For context, I was in the waiting area for a mental hospital, I’m guessing that would explain the amount of cameras?

That makes a lot of sense. Probably hospital/facility security and the intake or admin personnel’s systems.

Most contemporary CCTV systems are IP based. Not surprisingly, network security prevents a lot of cross network traffic (or even network interconnectivity) between different system openers. The cost of allowing those connections is far more than just putting in your own system. I have a significant airport client that has 6 cameras on one door going to a generator control room of a parking garage with some antennas on the top level. Between the airport authority, county (they own the airport), power company, cellular antenna provider, and a few Federal agencies, the real estate for cameras on that one door is quite limited.

I hope the hospital visit is a helpful one for whomever.

Thanks again, and yeah my friend should hopefully feel better after that visit.

I should have scrolled down. I see there is a fellow industry professional in the mix. My reply was unnecessary.

Typically this is done in places where it is important that a person cannot have blind spots and must be able to see what a person is doing at all times. This particular setup, the sensors are probably pointed at different directions and this was the best place to put the cameras.

I have also seen where you are in a regulated environment where the regulator requires access to the feed at all times, but you don't want them on your network (China), so you put 2 cameras up at the same time with 2 separate networks to allow for this.
