Capture surveillance video with 4 MP imaging and set framing at the camera using the 4.4-9.3 mm varifocal lens. The adjustment range supports a wider view of an entry, aisle, or shared work area at one end and a tighter view of a more distant target at the other. Its bullet-camera format provides a directional camera position for fixed scene coverage. IR illumination extends camera use into low-light conditions without requiring visible scene lighting. An integrated microphone adds audio capture at the same camera location, supporting video-and-audio review where site policy permits audio recording. These capabilities suit camera positions where lighting conditions change through the day or where a single fixed camera must cover a defined area after dark. Pelco SRXE4-4V9-EBT-IR1-B combines four specific selection points in the Sarix Enh 4 range: 4 MP resolution, a 4.4-9.3 mm varifocal lens, IR illumination, and a microphone. Select this configuration when lens adjustability, low-light support, and local audio capture matter more than a fixed focal-length camera configuration.
