Capture high-resolution surveillance coverage with an 8 MP fixed-turret camera that combines a 2.8 mm lens, dual-light night vision, an integrated microphone and an integrated speaker. The turret format provides a compact camera head for monitoring entrances, interior corridors, reception areas and exterior approaches where a fixed viewing position is required. Audio hardware at the camera supports captured sound as well as two-way communication. Dual-light night vision provides an additional low-light monitoring capability for scenes that must remain observable after ambient illumination drops. The fixed 2.8 mm lens suits applications requiring a wide-area view from a single camera position, such as doorways, walkways, loading areas and shared indoor spaces. An 8 MP image sensor supplies the resolution needed to retain fine scene detail when reviewing recorded video or viewing live footage. UNITED DIGITAL IPC3618SR-ADF28KMC-DL-H combines imaging, night monitoring and audio functions in one fixed turret camera rather than requiring separate audio hardware at the monitored point. Its distinguishing configuration is the combination of 8 MP resolution, dual-light operation, a 2.8 mm fixed lens, built-in microphone and built-in speaker. This makes it appropriate where camera-side audio interaction is needed alongside detailed video coverage.
