How to choose security cameras
The best camera isn't the one with the most megapixels, but the one that gives a useful image in the place and situation that matter. These are the criteria.
1. What you want to see
Watching a garden is different from identifying a face at the door or reading a number plate. First define each camera's purpose, then choose the model.
2. Resolution and lens
Higher resolution lets you zoom into detail, but field of view and distance matter just as much. A wide-angle lens sees a lot but with less detail at distance.
3. Night vision
Infrared cameras see in black and white in the dark; colour night vision needs some light. The surrounding lighting is key.
4. Backlight
Entrances with strong outside light need WDR (wide dynamic range) so you don't just see silhouettes.
5. Mountain climate
The camera must be rated for low temperatures, snow and rain, and properly protected when installed.
6. Wired and PoE
Wired PoE cameras are more reliable than wireless ones.
7. Recording
- Local (recorder or NAS): footage stays on the property.
- Cloud: off-site copy, but dependent on the internet and an external service.
8. Smart detection
Person and vehicle detection cuts false alarms from animals, shadows or vegetation.
