4K ULTRA HD 180° PANORAMA: Two lenses piece together a 180° wide-angle view in 4K resolution with no gap and little distortion, providing a panorama that covers much finer details. An ideal choice for your backyard or driveway. Note: If added to a Reolink NVR with Hw H3MB18/N2MB02/N3MB01, please first upgrade the NVR to the latest firmware version for a better viewing experience and switch to 6MP manually on mainstream on the monitor UI. | STRONG AND EFFECTIVE DETERRENCE: When a moving target is detected, the 1800-lumen floodlights and customizable siren will be activated to deter intruders powerfully. You can also use the two-way audio to warn off the unwelcome. | SMART PERSON/VEHICLE/PET DETECTION: With advanced algorithms to analyze shapes, the camera can detect humans, cars, and pets and send you relevant alerts. You can customize the sensitivity and alarm delay time to reduce unwanted alerts. | PLUG AND PLAY: Use an Ethernet cable to connect the PoE camera to a PoE NVR/switch. One cable handles the network connection and power supply, allowing you to finish installation and setup in minutes without much wiring clutter. Note: IEEE802.3at PoE switch/Reolink PoE NVR needed, not included. | MULTIPLE RECORDING OPTIONS: The camera supports motion-triggered, scheduled, and 24/7 continuous recording. Connect it to a Reolink NVR to build your PoE system and store your videos on the built-in large-capacity hard disk.
