Capture 4 MP video from a bullet-format surveillance camera while setting the field of view for the monitored area. The 2.7–13.5 mm variable-focal lens supports a wider view for nearby activity or tighter framing for more distant subjects. That adjustment is useful when camera positions, target distances, and scene boundaries vary from one installation location to another. UNITED DIGITAL IPC2324SR5-ADZK-H fits exterior-facing and extended-view camera placements such as building approaches, vehicle entrances, perimeter paths, loading zones, and covered walkways. Its bullet housing format provides a directional camera profile for aiming at a specific approach or area. Infrared night vision supports monitoring when visible ambient light is unavailable. This model is differentiated by the combination of 4 MP imaging and a 2.7–13.5 mm varifocal lens. A fixed-lens camera requires the installer to accept its predefined viewing angle, while this camera allows framing to be set during deployment for the scene in front of it. Select the wider end of the lens range when broad situational coverage matters, or narrow the view when a more focused area is required. The camera’s listed shipping weight is 1.12 lb.
