4K UHD & 180° PAN & MANUAL TILT, A WIDER VIEW PRESENTED: This 4K bullet surveillance Camera can pan 180 degree and supports auto tracking horizontally. It could be tilted manually to deliver super clear videos in a wide view. You can check almost every corner and capture as many details as you want. NOTE: The recommended installation height for RLC-81PA is 3m(or lower) and the angle is 0°-45° to provide better live-view experience.

SMART PERSON/VEHICLE/PET DETECTION: Smarter than you think, this camera can distinguish humans, cars, and pets from other objects and record when suspicious motion is detected. Only focus on what really matters and largely reduce false alarms.

INSTANT & EFFECTIVE DETERRENTS: You'll receive app push and email alerts once a motion event is detected. Spotlights and the siren will be triggered immediately to deter suspicious visitors. Customize the siren with your own voice for even better effects.

MULTI-USER REMOTE ACCESS & TWO-WAY TALK: The intuitive Reolink App & Client allows multiple users to remotely access the camera and view the live feed on it. And you can use the two-way audio to talk with the person on the camera side and get a response instantly.

SIMPLIFIED PoE INSTALLATION & MULTIPLE RECORDING OPTIONS : Thanks to the Power-over-Ethernet technology, power, data, and 4K UHD videos can be stably transmitted at the same time via an Ethernet cable. You can save video on a microSD card (up to 256GB, not included), a Reolink NVR, or an FTP server for 24/7 recording. Note: The power adapter is not included.
