Buying Guide: Key Purchase Considerations
- Resolution and image quality: Higher MP and 4K options provide more detail, especially for identification from a distance. Consider your screen size and the level of detail you need for evidence or monitoring.
- Night vision performance: Look for infrared range around 100 feet or more and features like IR-cut filters for day/night clarity. Weatherproof ratings (IP66/IP67) improve outdoor durability.
- Smart detection accuracy: Systems with person, vehicle, and animal detection help reduce false alarms. Check firmware support and whether you can fine-tune detection zones and sensitivity.
- Storage and expandability: A built-in HDD (commonly 2 TB) is standard, with options to expand up to 16 TB or more. Consider a model that supports network or local storage expansion and easy backups.
- Connectivity and installation: PoE (Power over Ethernet) simplifies wiring by delivering power and data over a single cable. Ensure your NVR has enough channels for future expansion and easy remote viewing via a mobile app.
- Remote access and privacy: Confirm that recordings are stored locally by default and review encryption and app security features for protecting footage during transmission and storage.
- System scalability: If you plan to add more cameras later, choose a kit or NVR with expandable channels and compatible camera options to avoid replacement costs.
