package
ultra-compact, high-performance security
CameraChip sensor
The OV7950 CameraChip™ sensor is developed
specifically for NTSC CCTV/video monitoring
security and surveillance applications. It is a highly
integrated video camera that packs a high level of
functionality. At only 1/4 inch format and using a
3.3V DC power supply, the OV7950 color image
sensor is ideal for applications requiring a small
footprint, low light, low power consumption, and
high performance.
The OV7950 supports NTSC composite video
output and can directly interface with a TV monitor
or another device with a 75 Ohm composite video
loading. The OV7950 excels in low light conditions
and can operate within a temperature range from
-20°C to 70°C.
Key features of the OV7950 include a new windowing feature
which allows customers to adjust their camera setup by
moving the sensitive area of the camera in either vertical or
horizontal directions. The OV7950’s Genlock function allows
the synchronization of two or more video sources. This
enables the development of very affordable closed-circuit
security monitoring systems that are very easy to set up,
making the OV7950 a very suitable product for consumer and
small business solutions.
In addition, the new OV7950 image sensor features a dual
dynamic overlay function, allowing for both dynamic and
static visual aid layer (text or graphics) within the image.
These are especially useful for text features in security
camera systems to identify each camera and location
individually.
