Buying Guide

What should you consider when picking a 3MP camera system?

• Deployment type: Do you prefer wired PoE for stability or wireless for easier installation?
• Storage needs: Local HDD capacity determines how long you can store footage before overwriting. Larger HDDs reduce the risk of gaps in surveillance.
• AI features: Look for human/vehicle detection to reduce false alerts. Adjustable detection zones help tailor sensitivity to your property.
• Night vision: Color night vision improves detail at night, but ensure infrared distance meets your property scale.
• Remote access: Check app reliability for live viewing and alerts on mobile devices.
• Expandability: If you anticipate needing more cameras, choose a system that supports additional channels or cameras without major overhauls.
