One or two doors, a hallway, maybe a balcony.
Most apartment break-ins happen at the front door, and most apartment camera setups fail for the same two reasons: the camera is a cloud doorbell that stops working when the wifi drops, and the footage lives on somebody else's server behind a subscription.
This is the smallest system we would actually install ourselves. Two cameras, a recorder that powers them over the same cable that carries video, and nothing that phones home.
One on the entry door, one covering the approach or a balcony slider. A third rarely earns its place in a flat — you end up with two views of the same hallway.
Infrared alone gives you clean black-and-white, which tells you someone was there. Dual-light switches to white light on motion, so you get clothing colour and a face. That is the difference between a report and an identification.
No subscription, no cloud account, no outage when the internet drops. The recorder sits in a closet and keeps recording.
Comfortable for a one or two-bedroom flat, a condo entry, or a small office suite. Roughly 2,000 sq ft of approach.
Half a day
Two cable runs and two brackets. The recorder needs a power outlet and a spare port on your router. No configuration beyond setting a password — the cameras are already paired.
