Puts 5 MP coverage at a doorway, gate, loading area, or perimeter approach into a fixed bullet-camera format. The 2.8 mm F1.0 lens establishes the supplied optical configuration, while the red and blue lights add a visible signaling function at the camera. That combination gives security teams a camera option where image capture and on-camera visual indication are both relevant. Alarm and audio interfaces distinguish this unit from cameras limited to video connections alone. They provide connection points for compatible external alarm and audio equipment, allowing the camera to participate in a locally integrated security installation. Interface requirements should be matched to the connected equipment and site design; this camera includes the physical alarm and audio interface capability named for the unit. UNITED DIGITAL IPC2B15SS-ADF28KMC-I1 is the 5 MP Tri-Guard 2.0 bullet configuration with a fixed 2.8 mm F1.0 lens. Select it where red-and-blue lighting and external alarm or audio connections matter alongside the stated resolution. Its fixed optical configuration suits installations that have already established the intended field of view at the mounting location.
