With so many new technologies, a lot of security cameras can now offer night vision through some very impressive infrared technologies. This is great news, right?
Unfortunately, there are a lot of cameras out there that can only offer an infrared range of up to 30 mitres and although this might sound decent enough, a lot of these cameras offer a low quality black and white image when faced with low light environments.
Well, I have some great news for you! The Dahua Starlight camera is lightyears ahead of the game when it comes to range, picture quality and day/night vision. So if you are looking for a camera that can give you the best technologies and at an affordable price, the Dahua Starlight camera is definitely one camera for you.
What’s more, you can have complete control of your security cameras from your mobile devices. Meaning you can view your unoccupied premises or business whilst away or at home for the night.
Advanced Technologies
Back-Illuminated CMOS Technology
The Dahua's Starlight range of security cameras features new and improved back-illuminated CMOS sensor technology.
Unlike typical front-illumination sensors, back-illuminated sensors increase the amount of light that enters each pixel. This enables the camera to produce extremely high-quality footage in low-light environments. Starlight cameras have a high sensitivity and less random noise, which effectively increases the S/N ratio. Dahua achieves this by implementing a photo-diode structure and on-chip lens that is optimised for back-illuminated structures.
A large range of Dahua cameras with Starlight technology utilises a Sony STARVIS™ sensor. Security cameras equipped with this technology can efficiently illuminate footage from dark environments.
Achromatic Lens
Dahua cameras are equipped with an achromatic lens, enabling them to produce the highest image quality possible. Achromatic lenses include a combination of concave and convex glass, which focuses the different colour wavelengths into a single plane.
Conventional CCTV cameras without an achromatic lens often experience colour fringing, sharpness, and blurry footage at night. This is exaggerated more if they are not IR corrected.
Smart Image Signal Processor (ISP) Upgrade Enhancement
The ISP converts the captured image into a digital form and performs many operations. These include autofocus, auto exposure and white balance, to refine and enhance images. ISP can correct for imperfections in sensor and lens uniformity, reduce noise, and perform contrast enhancement with Wide Dynamic Range technology.
Intelligent Video Functions
Nearly every camera on the market is now fully equipped with a range of intelligent video function and video analytic capabilities. Dahua Starlight is no exception, with each camera including built-in intelligent video system analytics (IVS). Video analytics minimises the need to spend hours processing video data, by quickly streaming relevant information and trigger alarms when required.
Diverse Solutions
Every premises, whether that's a home, business or property, has specific requirements for their particular application. That's why Dahua provides four variations of Starlight technology, each with varying abilities and price points.
Basic Starlight Technology
Basic Starlight Technology is the most affordable solution and is suitable for low-light performance, rather than complete darkness. This solution has sensitivity down to 0.009 lux. Featuring an IR cut filter, this solution is most suitable for moderate dark areas. For instance, Basic Starlight can be used in parking lots, stadiums and parks, all of which typically have ambient lighting, such as street lights.
Enhanced Starlight Technology
Enhanced Starlight is the next step up, producing exceptional images in near dark conditions down to 0.005 and 0.007 lux. Similar to Basic Starlight, this solution also features an IR cut filter, though exclusively utilises broad-spectrum 2MP sensors.
As shown in the image below, the footage produced by Enhanced Starlight Technology is easy to interpret and detailed.
Starlight+ Technology
Equipped with a 4/3" sensor, IR cut filter and smart imaging algorithms, Starlight+ Technology provides exceptional colour details in near darkness, down to 0.0005 lux. Additionally, this solution has little to no noise or colour distortion.
As Starlight+ Technology is suited to dark environments, this solution is ideal for rural or public areas with no ambient lighting.
Night Colour Technology
Night Colour Technology is the most sophisticated solution that produces extremely crisp and clear full-colour images in ultra low-light scenarios. This solution combines an achromatic large-aperture lens, ISP and high-performance sensor.
This technology does not have an IR cut filter or illuminators due to its superb low-light sensitivity, hence, this solution produces colourful images 24/7. However, to produce fully saturated colour images, at least 1 lux of ambient light is recommended.
Night Colour Technology is perfect for applications where full-colour images are required 24/7 in environments with very low ambient lighting.
Why do I choose Dahua Starlight?
With sophisticated technologies coupled with a variety of smart features, seeing in the dark is no longer a problem. With a varied range of solutions, Dahua Starlight cameras can easily be tailored to suit many different applications. The camera superb design and technologies, tapped with their user friendly and mobile device capabilities make Duhua Starlight cameras the perfect camera for my customers.
