13 Low-Light Video Surveillance Tips to Enlighten Your Solutions
So if companies are buying sensors of the same size and resolution from the same supplier, how can one product be superior or inferior?
That’s where processing comes into play. So all things being equal with two cameras using the exact same sensor (and the same lens), the proprietary processing technology is where all the “magic” takes place.
Having said that, many manufacturers also employ the same OEM processor, from companies like Amberella or Texas Instruments, and then tweak them. The control of tuning the image is key.
You can tune an image during daylight to perfection, but to find that the same level of tuning at night under a sodium vapor light, or in complete darkness, does not work at all.
Tuning an image is a very exact and time-consuming science. Some companies just use the default image path in the processor. The camera will work fine but it won’t be better.
Image toning, noise suppression, and the ability to maintain color and contrast in low light is what differentiates one camera manufacturer from another.
