CCTV security systems
What a modern CCTV system includes, how to size coverage, and what to check before you buy or upgrade.
Snapshot
Key takeaways
- A CCTV system is cameras plus recording, power, networking, and a way to review footage.
- Coverage goals should drive camera count and lens choice, not the other way around.
- Retention, remote access, and monitoring are separate decisions from image quality.
- Plan cable runs, mounting, and lighting before you lock a bill of materials.
What a CCTV system includes
A CCTV security system is more than cameras. You need capture, transport, storage, and review. Skip any one of those and the system fails when you need evidence.
- Cameras matched to distance, light, and field of view
- Recording (NVR, hybrid, or cloud) with enough retention
- Power and network design that stays stable
- A client or app path to search and export footage
How to choose
Walk the site at the times that matter. Note glare, shadows, and choke points. Then map cameras to those moments instead of spreading hardware evenly across walls.
Questions
FAQ
Do I need an NVR or is cloud enough?
NVRs keep footage on site and can work without internet. Cloud helps with remote access and off-site copies. Many sites use both: local record plus selective cloud backup.
How many cameras do I need?
Count the moments and entries you must cover, then place cameras for those views. A smaller set of well-aimed cameras beats a large set of overlapping blind spots.
