With an IP65 weather rating, the SIR-4150N is suitable for both indoor and outdoor installations. An ICR filter provides day/night switchover. Sensitivity of just 0.3 Lux @ F1.2 Color, 0.002 b&w and 0 Lux with IR LEDs on provides optimal around-the-clock surveillance even in low light and total darkness.

Twenty-four (24) super bright IR LEDs, four times as bright as normal IR LEDs, provide a 100' effective IR range. Proprietary Samsung Super Noise Reduction (SSNR) further increases picture quality by eliminating noise in low light and provides DVR storage savings. Signal-to-noise ratio is a robust 50dB. A 3.8-9.5mm varifocal lens allows installers to adjust the field of view to suit each scene.

Motion detection and 4-zone privacy masking are provided, along with RS-485 control. Features are accessible via on-screen display (OSD). A 12VDC power supply and sunshield are supplied. The SIR-4150 is ideal for surveillance in any location in which adequate lighting is unavailable or would be too intrusive, including retail, industrial and high quality residential.
