High-Performance, Cost Effective Video Capture
for Surveillance Applications
OV7959 NTSC/PAL product brief
lead free
available in
a lead-free
package
The OV7959 is a high-performance and cost effective
CMOS image sensor developed specifically for
surveillance applications. Based on OmniVision's
advanced OmniPixel3-HS™ technology, the OV7959
achieves optimum low-light sensitivity and power
efficiency, making it an excellent solution for video
capture in varying conditions.
The 1/3.6-inch image sensor supports both NTSC and
PAL output formats. The OV7959 is capable of
operating in extreme low-light conditions and is capable
of operating across a wide temperature range of -20°C
to 70°C. It has superior IR performance and utilizes very
low power. It also supports a built-in OSD function.
Advanced image processing functions, including gain
control, white balance, and aperture and defective pixel
correction are all programmable through the serial
camera control bus (SCCB) interface. Other key
features of the OV7959 are the 16-zone automatic
exposure control, horizontal and vertical windowing
capability and extremely low dark current.
