Commercial Camera System

A property manager with retail on the ground floor and offices above it asked for cameras that would actually settle disputes: the lobby, the corridors, the parking lot, the loading dock, and the sales floor and registers of the two retail tenants. Coverage was the easy half. The hard half was everything the cloud camera vendors wanted in exchange. Per-camera monthly fees across forty-odd cameras, footage of a retail floor and its customers living on somebody else’s servers, AI analytics that meant uploading every frame to be processed, and a licensing model that got more expensive every time a camera was added. Two of the tenants handle client records and were never going to sign off on that. The requirement came back as one sentence: everything stays in the building.

Start with the recorder, because on this job it is the argument. A UniFi Network Video Recorder sits in the building’s telecom room with eight drive bays configured as a RAID set, and every camera in the property records to it continuously. Retention is a function of how much disk is in that chassis, so it was sized once, up front, for the number of weeks the manager and the tenants agreed they needed. There is no per-camera license and no monthly recording fee, which is why adding the ninth camera to a retail floor is a hardware conversation and not a budget conversation. The recorder takes redundant power and has a 10G link, so it keeps up with forty-odd 4K streams without being the bottleneck.

The AI is the part people assume has to happen somewhere else, and it does not. Each G6 camera runs its own detection engine on the camera itself, and the recorder adds AI event analytics on top of that. Person, vehicle and license plate detection all happen inside the property. The practical effect is that alerts arrive in seconds rather than after a round trip to a data center, and the analysis works exactly the same on a Sunday when the building’s internet is down. The privacy effect is the one the tenants cared about: no frame of a sales floor, a customer, a corridor or a client leaves the building in order to be analyzed, because there is nothing outside the building doing the analyzing.

That changes what the system is worth day to day. Smart search means the manager stops scrubbing timelines. “Show me every person at the loading dock between two and four on Tuesday” is a filter, not an afternoon. License plate detection logs every vehicle into the lot after hours. When a retail tenant reports a shrink problem, we pull the register camera and the exit camera on the same timeline and hand over an export that is cryptographically verified, so the file can be shown to be unaltered when it reaches a police report or an insurance claim.

Permissions were designed before a single camera went up. The property manager sees the whole property. Each retail tenant sees their own sales floor, their own registers and their own back-of-house door, and nothing belonging to the tenant next door. The office tenants see the corridor outside their suite and nothing else. Cameras covering the boiler room, the main electrical service and the telecom racks are manager-only, and a door opening in any of them at two in the morning is a smart detection with a clip attached rather than a discovery the following week.

A note on the features we did not turn on. Face recognition exists in this platform, and we leave it off unless a customer specifically asks for it and has thought through their own notice and policy obligations, which in a retail setting are not trivial. Privacy zones black out the sidewalk, the public road and the neighboring property in both the live view and the recording. A camera system that a tenant does not trust is a camera system that gets unplugged, so the defaults here are deliberately conservative.

Everything is watched from one place. The manager and each tenant use the same app on iPhone, Android, Mac or Windows, and remote access is encrypted. The video itself never moves; what travels is an encrypted view of it, on request, to a person who has been granted the right to see that camera.
