Closed-circuit television (CCTV) historically referred to analog cameras wired to a local recorder; most new installations at HOAs, apartment communities, and commercial sites in the Sacramento region now use IP (network) cameras that send digital video over Ethernet or Wi-Fi to a recorder or cloud service. Resolution, lens angle, and placement determine whether footage is useful for identifying a face or license plate versus simply showing that an event occurred.
Cameras perform differently across a real property: a parking structure entrance may need a wide dynamic range lens to handle headlight glare, while a package room may need a lower, angled mount to capture faces rather than the tops of heads. Weatherproof housings, adequate lighting, and lens cleaning schedules affect image usability more than the camera's marketed resolution.
Common failure modes include camera drift from a bumped mount, retention periods too short to cover a delayed police report, and blind spots created by landscaping growth or parked vehicles. Cameras also do not intervene — they document after the fact unless paired with live monitoring or an officer who reviews feeds during rounds.
In a patrol program, officers may use camera views to plan a route around blind spots, and supervisors pull footage to corroborate an incident report or a trespass notice. Camera systems and patrol staffing are complementary, not substitutes for each other.
