YI Pro
Score: 79/100Rankings

The YI Pro 2K 3-PC bundle offers three plug-in indoor Wi-Fi cameras with 2K resolution and AI-driven detection for budget-friendly home monitoring. Its main limitation is the requirement for a paid cloud subscription to access full AI features and the lack of pan-tilt coverage. It is best suited for budget-conscious families needing multi-room indoor monitoring where outlets are nearby.

The Amcrest ASH21-B is a compact 1080p indoor WiFi camera with pan/tilt capabilities and hardware-based AI detection. It offers versatile storage options and sound monitoring but is limited to 2.4GHz WiFi. It is ideal for nanny/baby monitoring and pet cams without mandatory subscriptions.
