Dahua's Starlight and Night Color technology
Updated: Sep 3, 2020
If you are looking to provide security to your home or office during night time hours, or in darker than usual areas, you'll need IP surveillance cameras that feature good low-light technology.
Thankfully, at SRH Installations, we have shopped around and only provide the best products for our customers. We know that choosing the right camera can be tricky because each application has its own set of challenges, lighting constraints, and budget limitations.
That said, after years of experience in installing high quality CCTV cameras for our clients, we can safely say we work with the best and most robust camera out there.
Why we love Dahua Starlight
Starlight CCTV cameras are the most recent upgrade to infrared. With Starlight CCTV, you can get clear images in low light, in full colour!
We install the Dahua range because they offer excellent examples of the quality of the images you can achieve in low light conditions. The end result is so impressive, we think you'll be surprised at the quality of the images that can be achieved.
Many Starlight cameras allow you to add on analytics with the camera for greater functionality and more effective recordings.
Dahua Starlight cameras use a Sony STARVIS CMOS sensor, which is a back-illuminated pixel technology providing a set of optical features to balance light throughout the scene. A back-illuminated structure moves the photosensitive surface closer to the light, increasing the amount of light that enters each pixel.
Lens aperture controls the amount of light that passes through the lens and into the body of the photosensitive surface of the camera. Dahua cameras with Starlight technology feature a maximum aperture of f/2.2 to allow as much light as possible to pass through the lens and hit the sensor.
A large aperture coupled with advanced Image Signal Processing (ISP) technology, Dahua’s proprietary image processing algorithms, and STARVIS image sensors, allows these cameras to produce identification-level images in near-dark conditions.
Image Signal Processing
ISP identifies and corrects imperfections caused by the lens, colour filter, or sensor. Dahua cameras with STARVIS offer two times the definition of Exview HAD CCD sensors and are capable of illuminating dark environments and incorporating near-infrared light for clear recording at night.
Dahua cameras can come with one of three different Starlight technology options, and one Night Color, depending on requirements and scenarios.
