CAMERA SYSTEM GUIDE
What Is CCTV? Meaning, Camera Systems & Installer Checklist
CCTV is short for closed-circuit television. In practice, a video surveillance system may include cameras, recording or storage, monitors, and networking equipment. The right setup depends on what you need to see and how you will use the footage.
Plan around the job each camera must do
Start with two questions: what is in the scene, and what decision should a viewer be able to make from the video? NIST’s public-safety video guidance uses those questions to define video requirements. A view meant to show that someone entered a doorway has different framing needs from a view intended to distinguish a delivery label or vehicle plate.
- Mark entrances, loading areas, cash-handling areas, and other specific scenes.
- Consider distance, viewing angle, lighting, reflections, and night conditions at each location.
- Choose image detail for the task instead of selecting a camera by resolution alone.
Decide how recording and access should work
Ask whether recording will stay on a local recorder, use cloud storage, or combine both. Compare the storage period, recording schedule, remote-access requirements, network capacity, power needs, and any recurring fees. Confirm who can view or export recordings and how access is removed when a staff member leaves.
For connected camera equipment, CISA recommends changing default settings, using unique passwords, enabling encryption where available, and keeping device software and firmware updated. Ask the installer to explain how the system will be secured and maintained after installation.
Questions to ask a camera installer
- Which areas will each camera cover, and what detail can the view reasonably capture?
- What recorder, storage plan, retention period, and ongoing fees are included?
- What network, cabling, and backup-power work is required?
- How are remote access, user permissions, updates, and support handled?
- What installation, warranty, and maintenance work is included in the quote?
- Which state or local licensing requirements apply to this project, and how can I verify them?
Ask for a site-specific scope and written quote. Confirm the company’s current services, service area, credentials, price, and availability directly before hiring.
Common questions
What does CCTV stand for?
CCTV stands for closed-circuit television, a term used for video surveillance systems.
Is CCTV the same as a security camera?
A camera is one component. A complete surveillance system can also include recording or storage, monitors, network equipment, and the software used to view footage.
How long should security footage be stored?
There is no single retention period for every property. Set it based on operational needs, storage capacity, privacy obligations, and any applicable rules. Ask the installer to show how the proposed storage period was calculated.
