OMNIVISION OV07449-C10A

OV7949 NTSC/PAL
product brief
high-performance security CameraChip sensor
available in
a lead-free
package
The OV7949 CameraChip™ sensor is known as one
of the most highly integrated true video NTSC/PAL
camera systems. With high functionality and
proven excellence in extreme low light settings, the
OV7949 image sensor can compete head-to-head
with the highly competitive CCD segment of the
security surveillance market.
With an ever growing security surveillance camera
market, the OV7949 image sensor is the most cost
efficient solution for applications requiring a high
performance video camera with a small footprint,
low voltage, low power consumption and high
performance. The OV7949 excels in low light
conditions and can operate within a wide
temperature range from -20°C to +70°C.
Key features of the 1/3 inch OV7949 include reduced
blooming/smearing effects, and a Genlock function, which
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 OV7949 a very suitable product for consumer and
small business solutions.
The OV7949 supports NTSC/PAL composite video output and
can directly interface with a TV monitor or another device
with 75 Ohm loading. These features and functions of the
OV7949 make it a strong solution for any surveillance camera
application.
