Application

SONY's Exmor has already been deployed in consumer electronics such
as digital cameras and digital camcorders and has proven to be a great
success in capturing video in low light conditions. Thus, with the IP8151,
which features the IMX035 sensor specifically designed for the security
market, this next-generation camera can surpass the performance of
traditional cameras in low light environments.
Although most IP camera vendors recommend a minimum of 40 pixels
per foot in a scene to capture details such as license plates or faces,
during nighttime and poor lighting conditions, this can grow to as many as
120 pixels per foot. With the improved light sensitivity of the IP8151, a
scene which may have required 120 pixels per foot previously may be
recognizable at 95 pixels per foot or lower, even in low light conditions!
Thus, a scene which may have required a higher megapixel camera may
now easily be captured with the 1.3MP IP8151 camera.
Let's look at a real-world example where security is prevalent: casinos.
The lighting in the interior of a casino or around the gaming machines
may not provide enough ambient lighting to monitor activity clearly. At the
same time, bright lighting may not always be possible as they may
interfere with the atmosphere or décor of the locale. In such cases, the
