YI 2K Outdoor Camera YPS4123 Surveillance Security System

2K Outdoor Surveillance Camera

The YI YPS4123 is a corded Wi-Fi camera built for outdoor security. It records 2K resolution video with full-colour night vision and a motorised 360° pan-tilt mechanism. On-device AI handles human detection, abnormal sound alerts and motion tracking without cloud latency. The IP65-rated housing withstands rain, dust and temperature extremes for year-round mounting on farms, warehouses or home exteriors.

Thermals Noise and Power Draw

Mains power removes battery constraints, enabling continuous 24/7 recording and sustained AI processing. The 2.4 GHz Wi-Fi radio provides extended range and stable throughput through walls and across yards. With no internal fan or moving parts beyond the pan-tilt motors, the unit runs silently. The IP65 seal protects the electronics from moisture and dust ingress during storms or dusty conditions.

128 GB Local Storage Limit

Footage can be saved to a micro SD card up to 128 GB, which is sold separately. Cloud backup via YI Cloud is also supported for off-site protection. Buyers who need larger local capacity or NAS integration without a card slot should look elsewhere. The fixed 2.4 GHz Wi-Fi interface means the camera will not connect to 5 GHz-only networks.
