Choosing security cameras can feel confusing. WiFi, wired, megapixels, recording storage—what do you actually need?
Start with your property, the areas you want to monitor and your total budget. These seven checks will help you make a more informed purchase.
1. Decide what each camera needs to see
List your priority areas: the gate, driveway, front door, back entrance and accessible side passages.
Then decide what you need from each view. Seeing that someone entered your yard is different from capturing a useful image of their face. Camera position, distance and lighting all affect the result.
2. Understand what “wireless” means
A WiFi camera sends video over a wireless network, but many models still need a power cable. Battery models have different charging and recording requirements.
Compatible Power over Ethernet—or PoE—cameras receive power and transmit video through an Ethernet cable. Check the power requirements before choosing your installation points.
3. Check the picture after dark
A clear daytime demonstration doesn’t tell the whole story. Think about the lighting at your gate and driveway at night, including headlights and nearby walls that could reflect infrared light.
Megapixels are only part of image quality. Camera placement, exposure and lighting also matter. Ask how the proposed camera will perform in your actual conditions.
4. Confirm how footage will be recorded
Before paying, ask:
- Is recording storage included?
- Does the camera use a memory card, recorder or cloud service?
- Is recording continuous or triggered by events?
- Are there subscription charges?
- What happens when storage fills up?
Ask for an estimated recording period based on your chosen settings.
5. Separate internet access from local recording
Some systems can continue recording locally when the internet connection fails, provided they still have power and suitable storage. Remote viewing and online notifications generally need a working internet connection.
Confirm what your exact model supports before buying.
6. Plan for power interruptions
Ask which devices need backup power. Depending on the setup, that could include cameras, a recorder, a PoE switch and your router.
Backup runtime depends on the equipment’s power demand and the backup unit’s capacity. Request an estimate for the complete setup.
7. Compare the complete installed cost
Check whether the quotation includes storage, cables, power supplies, mounting accessories, installation and delivery.
For a multi-camera system, also confirm that the cameras and recorder are compatible. A clear, itemised quotation makes packages easier to compare.
