Safety and Security — FAQ
Are wired or wireless cameras better for garage security?
Wired cameras excel in attached garages with stable power and poor WiFi penetration through metal walls. Wireless systems suit detached garages where trenching cables is impractical, though solar panels or battery swaps require seasonal maintenance.
How many cameras do I need for a 2-car garage?
Position one camera above each garage door corner facing inward, plus a third covering the side entry door. For workshops storing tools, add a fourth camera covering workbenches. Wide-angle lenses can reduce camera count but sacrifice detail at distance.
What resolution is needed to read license plates in a garage?
Minimum 2K (3MP) resolution is required for reliable license plate capture from 20 feet. Position cameras at 8-10 feet height angled downward at 30 degrees. 3K or 4MP systems provide clearer results in low light and with dirty or obscured plates.
Can garage security cameras handle extreme cold and heat?
Choose IP67-rated cameras operating from -40°F to 140°F. Battery capacity drops 30-50% below freezing—solar charging helps maintain power. Wired systems avoid battery issues entirely and perform reliably across all temperature extremes.
Do I need a subscription for garage security cameras?
No. All tested systems offer local storage (HDD or SD card) with no monthly fees. Subscriptions add cloud backup and advanced AI features, but for garages where incidents are rare, local storage provides weeks of footage without recurring costs.
How do I prevent false alerts from garage door movement?
Use AI detection to differentiate humans/vehicles from general motion. Create custom detection zones that exclude the overhead door area. Adjust sensitivity settings and use schedule modes to disable alerts during regular comings and goings.
