Buying Guide
What to consider when choosing a 4MP camera for a phone app setup
- Resolution and clarity: 4MP delivers clear daytime video; consider 2.5K options for crisper detail in CINMOORE models.
- WiFi compatibility: Dual-band (2.4/5GHz) improves connection stability. If you have a crowded network, prioritize dual-band devices like ARENTI and USOGOOD.
- AI motion detection: Look for human/animal detection to reduce false alerts. Auto tracking helps when you can’t actively monitor feeds.
- Night vision: Infrared or color night vision extends monitoring into low light; check range and lighting conditions in your home.
- Two-way audio: Useful for baby soothing or pets; ensure microphone and speaker quality meet your needs.
- Storage: Cloud storage vs local microSD. Local storage is private but may require manual retrieval; cloud offers easier access across devices.
- Multiple cameras: If you plan to cover several rooms, consider packs or bundles (like 2-pack options) for synchronized viewing.
- Power options: Plug-in cameras are common, but battery-powered models offer flexibility. For outdoor use, verify weather resistance.
- Privacy and security: Check data encryption and access controls. If privacy is a priority, prioritize devices with robust local storage options.
