Best Security Cameras

Resolution and Night Vision

Look for at least 1080p resolution for clear facial identification at 15-20 feet. Budget cameras offer 720p, while premium models provide 2K-4K. Night vision range matters—infrared LEDs typically illuminate 20-30 feet, while spotlight cameras extend this to 40+ feet. Color night vision requires ambient light or built-in spotlights.

Power Source and Connectivity

Battery cameras offer flexible placement but require recharging every 2-6 months depending on activity. Wired cameras provide continuous recording but limit installation locations. WiFi cameras need strong signal (2.4GHz works best for range; 5GHz for speed). Some models work without WiFi, storing footage locally—ideal for privacy-conscious users or unreliable internet.

Storage Options and Costs

Cloud storage typically costs $3-10/month per camera for 30-60 days of footage. Local storage via microSD (up to 256GB) or base station eliminates monthly fees but risks theft of footage. Consider total cost over 3 years: a $50 camera with $10/month cloud costs $410 total versus a $150 camera with free local storage.

Smart Features and Integration

Motion detection zones reduce false alerts from trees or cars. Person detection (vs. general motion) cuts notifications by 70-80%. Two-way audio quality varies—test reviews mention echo and delay. Smart home integration (Alexa, Google, HomeKit) enables voice control and automation routines like turning on lights when motion detected.
