A modern CCTV system does far more than record video. It deters theft, protects staff, helps resolve disputes and lets owners check their premises from a phone. For many businesses in Dubai, a properly designed surveillance system is also part of meeting regulatory requirements. This guide explains the main camera types, how recording and storage work, and what drives the cost of a business CCTV system.
IP Cameras vs Analogue Cameras
Most new installations use IP cameras, which send high-resolution video over the network and are powered through a single PoE cable. Compared with older analogue systems, IP cameras offer sharper images, smart detection features, remote viewing and easier expansion.
Choosing the Right Camera Type
- Dome cameras – discreet and vandal-resistant, ideal for offices, shops, corridors and receptions.
- Bullet cameras – visible deterrent for car parks, perimeters, gates and warehouses.
- PTZ cameras – pan, tilt and zoom to cover large areas such as yards and building exteriors.

Resolution: How Many Megapixels Do You Need?
For most business areas, 4MP to 5MP gives clear faces and details. Use higher resolution or a narrower lens for entrances, cash counters and number plates, where identification matters most. Night-vision range (IR) and wide dynamic range (WDR) matter as much as megapixels for real-world image quality.
Recording and Storage
An NVR (network video recorder) stores footage from all cameras. Storage needs depend on the number of cameras, resolution, frame rate, compression (H.265 saves space) and how many days of footage you must keep. Always use surveillance-rated hard drives designed for 24/7 recording, and plan for retention periods that meet your business or regulatory requirements.
Network and Power
IP cameras need a reliable PoE switch with enough power budget for all cameras, ideally on a separate VLAN from office computers. Connect the NVR and switch to a UPS so recording continues during short power cuts.
Regulations in Dubai
In Dubai, CCTV for many types of business is regulated by the Security Industry Regulatory Agency (SIRA), which sets requirements for camera coverage, recording retention and approved installers. Before installing, check whether your business category is covered and what specifications apply.
What Affects the Cost of a CCTV System?
- Number and type of cameras
