Technical content

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. available in a lead-free package OV7949 NTSC/PAL high-performance security CameraChip sensor product brief 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.
