Buying Guide
- Display size and resolution: Higher resolution provides crisper visitor images. If you mainly want a deterrent and quick recognition, 720p or 1080p options are sufficient.
- Field of view: A wider angle (120°) reduces blind spots, but may require more installation space on the door frame. Consider door thickness and opening sizes.
- Power and connectivity: Battery-powered units offer straightforward installation but require battery maintenance. Wired or USB-powered models may provide consistent performance but involve wiring.
- Two-way audio: If you want to communicate with visitors, choose models with built-in mic and speaker or app-based intercom.
- Night vision: Infrared or low-light sensors improve nighttime visibility, essential for 24/7 monitoring.
- Storage and data: Some devices support local memory, cloud storage, or both. Consider whether you need local retention or cloud access or both.
- App compatibility: Check whether the device works with your preferred smart home ecosystem (e.g., Tuya) and whether it supports multi-device access.
- DIY vs professional install: Some models emphasize easy installation with standard door holes; others might require tool usage or professional assistance.
