OV7950 product brief available in a lead-free 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.
