How to Choose a CCTV Camera System for Your Shop or Home
A CCTV system is only useful if it's specified correctly for the space it's covering. Here's what to check before you buy.
1. Count your coverage points, not just "how many cameras"
Walk your shop or compound and list every point that needs coverage: entrances, exits, the till or safe, blind corners, and any external gate or parking area. This tells you the camera count you actually need, rather than guessing.
- Small shop / single room: 4-channel kit (4 cameras)
- Medium shop / small compound: 4-8 channel kit
- Larger compound, multiple buildings or entrances: 8+ channels, possibly across more than one kit
2. Indoor vs outdoor cameras
Outdoor-rated cameras are weatherproofed and typically handle glare and low light differently than indoor cameras. If any camera will be mounted outside — covering a gate, compound or shopfront — confirm it's rated for outdoor/weather exposure, not just marketed as "CCTV" generally.
3. Night vision
Most break-ins and theft attempts happen at night or in low light. Check the camera's infrared (IR) range — a range of 20-30 metres is standard for most shop and home setups, and covers the difference between a grainy silhouette and a usable face/number-plate image.
4. Storage: how much footage history do you need?
Footage is stored on a hard drive connected to the DVR/NVR box. More cameras recording continuously means footage gets overwritten sooner on a given drive size. If you need a longer history (for example, to review footage from two weeks ago), choose a larger hard drive or ask about motion-triggered recording, which uses storage more efficiently than continuous recording.
5. Power backup
A CCTV system that stops recording during a power outage defeats much of its purpose, since break-ins often happen when the area looks unmonitored. Pair your system with a UPS or inverter so it keeps recording through outages.
Tip: Ask whether the kit supports remote viewing via a phone app. Being able to check your shop or home from anywhere, not just from an on-site monitor, is one of the most useful features of a modern system.
6. Installation
Camera positioning affects how useful footage actually is — too high and you lose facial detail, badly angled and you miss the exact area that matters. We supply CCTV kits and offer installation support in Minna and surrounding areas so cameras are positioned correctly from the start.
Frequently Asked Questions
For most small shops, a 4-channel kit covers the essentials: the entrance, the till/counter area, the main floor and a back exit or stockroom. Larger shops or those with multiple entrances may need 8 channels.
Only if the system is connected to a backup power source — a UPS, inverter, or the CCTV DVR's own battery backup if it has one. Without backup power, recording stops during an outage, which is exactly when you're most exposed.
This depends on your storage (hard drive) size and how many cameras are recording continuously. A typical setup retains 2-4 weeks of footage before older recordings are overwritten; larger drives extend this.
Most modern CCTV kits support a companion app for remote viewing over the internet, in addition to local viewing on a monitor. Confirm this feature when choosing a kit if remote access matters to you.
