Image sensor provides security with
little light
Day/night IP security camera makes use of the low-light performance of the OV7725 VGA image sensor.
The OV7725 VGA image sensor from OmniVision Technologies has been selected by leading global surveillance technology innovator, Zavio, for use in its next-generation F511E day/night IP security camera solution The F511E, which is scheduled to be launched commercially in June 2008, is a dual-mode IP security camera designed primarily for indoor security applications in the commercial and domestic markets

Image sensors chosen for IP cameras
The OV7725 is a quarter-inch VGA CameraChip sensor built on OmniVision's OmniPixel2 technology for high performance in low-light conditions.
Compact camera sensor suits laptop use
OmniVision Technologies' OV7725 VGA CameraChip sensor delivers the light sensitivity required for the low light conditions in which most consumers use their notebook computers.
The camera's dual-mode employs an automatically removable IR-cut filter mechanism, which enables superior imaging performance in both daytime and nighttime conditions.
By day, the camera provides full colour imaging with the IR-cut filter in place.
As light levels fall, the camera automatically moves the IR-cut filter to the side and transitions to black and white mode with active infra-red LED illumination, enabling full night vision capability.

According to OmniVision Technologies, the OV5610 5Mpixel camera chip has already achieved eight design wins in digital still camera and video camera markets.
The F511E incorporates advanced video features such as simultaneous Motion JPEG and MPEG-4 real time video streaming, as well as mobile phone video streaming using 3GPP.
The camera also offers integrated multiple-window motion detection, I/O ports for connection to an external alarm or sensor, power over Ethernet (PoE), two-way audio with a built-in microphone and the core of all Zavio cameras, stable and powerful firmware.
"With the F511E, we are providing a very versatile IP camera solution at a revolutionary price-performance ratio", says Shau-Chau You, Product Manager at Zavio.
"We selected the OV7725 for its best-in-class performance in all lighting conditions and its low power consumption, both of which are critical qualities in modern security applications".
"The OV7725 represents one of the very best solutions on the market".
"Delivering exceptional low light performance at a reasonable price has been a key objective for our CameraChip security vision solutions", says Todd Koelling, Senior Director of Marketing - Emerging Product Markets at OmniVision.
"This innovative solution from Zavio is an example of the benefits of our system-on-chip CMOS cameras, which offer the high quality standards traditionally linked to CCD based cameras, while dramatically reducing overall system cost".
The OV7725 is a highly integrated quarter-inch CMOS CameraChip sensor that provides the full functionality of a VGA camera and image processor on a single chip.
Built on OmniVision's proprietary OmniPixel2 technology, the OV7725 offers unparalleled performance in low-light conditions, and can operate at 60 frames per second in VGA mode, or 120 frames per second in QVGA.
The OV7725 is currently available in volume quantities in a lead-free 28-pin CSP2 package.
