What camera resolution do I really need for clear identification?
1080p is the minimum for usable detail at close range, like a front door within 10–15 ft. If you want clearer plates or faces across wider areas—say 30–60 ft—step up to 2K or 4K. Pair higher resolution with strong night vision and proper mounting height (around 9–12 ft) for the best results.
Do I need an NVR/DVR if my cameras offer cloud storage?
No, but it can be a smart backup. Cloud is convenient and accessible anywhere, while an NVR/DVR gives you local control, longer retention without monthly fees, and reliability during internet outages. Many users run both: cloud for quick clips and an NVR for full-length recordings.
How high should I mount outdoor cameras and motion lights?
Mount outdoor cameras around 9–12 ft high to capture faces and avoid easy tampering. Motion floodlights work well at 8–10 ft for wide, even coverage. Angle both slightly downward to reduce glare and catch features like hats and hoodies.
Are battery-powered cameras reliable in cold UK weather?
Modern battery cams handle chilly snaps well, but cold temps can shorten battery life. Expect quicker drain below 40°F. To compensate, reduce motion sensitivity, trim activity zones, and use scheduled recording. If the spot has power, a wired option with a heater-rated housing is even more resilient.
What’s the difference between PIR and radar motion detection?
PIR (passive infrared) detects changes in heat, making it great for spotting people and pets with low power use. Radar (often 24 GHz) measures movement and distance more precisely and can reduce false alerts from shadows or insects. Some premium cameras combine both for smarter, more accurate detection in the 20–70 ft range.
