ANNKE UHD 3K Wired Add-on Security Cameras (4pcs) — 2960×1665@20fps, Built-in Mic, 2.8mm f/1.2 Lens (129° FOV), Smart Dual Light, 100ft Color Night Vision, IP67

4-camera kit with true 3K Super HD: Each ANNKE unit records at 2960×1665@20fps, using a 2.8mm lens with an f/1.2 large aperture to deliver a 129° diagonal field of view. The 16:9 aspect ratio produces a wider, more display-friendly image than older 4:3 formats and supports continuous 24/7 video and audio recording. Smart Dual Light for clearer night images: In the default smart dual light mode the camera uses infrared illumination for routine monitoring; when motion is detected the white light activates and the infrared turns off so you get a full-color image of the event. You can also set the unit to full infrared or full white light mode. Infrared fill light reaches up to 25 m and the white light provides bright night imaging up to 20 m. (Note: a DVR that supports AI is required to enable the dual light function.) Built-in audio via coaxial cable: A microphone is integrated so audio is recorded over the coaxial connection; microphone recording can be disabled from the camera menu. Built for outdoor use: Rated IP67 for weather resistance and tested to operate between -40 °C to 60 °C (-40 °F to 140 °F), this camera is suitable for installation indoors or outdoors in most climates.
