Darkfighter vs starlight3/1/2023 ![]() This is a really useful feature which can make a camera dedicated to one task, like LPR, much more efficient.Īlong with most manufacturers Axis use CMOS sensors. In terms of fine tuning one example is: adjusting the temporal noise filter strength for better facial detection rates. Understandably Axis are quiet on what exactly goes into Lightfinder 2.0. Visually this is a step change for low light technology, so how has this been achieved? For scenes which demand high quality, usable footage around-the-clock, you’d go for Lightfinder 2.0. The image on the left is enough for general observational surveillance. The difference in colours, details around faces and depth of field is apparent. Lightfinder and Lightfinder 2.0 with comparable cameras in full darkness. The one on the left uses the original Lightfinder, while the one on the right uses 2.0. The images taken at the same time on two P series cameras. Take a look at the images below for a comparison. We should mention that the original Lightfinder still produces usable video footage in low light. The main difference between the original and Lightfinder 2.0 is in the detail and colour rendition. With the performance improvements due to Axis’ ARTPEC-7 chip set, lots. Some manufacturers have improved general low light performance without branding their technology separately, like Sony (renowned for their low-light performance). For example: Bosch – Starlight Hikvision – Darkfighter and Mobotix – Moonlight to name a few. Since then other manufacturers have followed suit and improved low light performance and given their respective technologies catchy names too. By harnessing the existing available light in a near-dark scene to create a realistic colour image, it produced useable security footage. When Lightfinder was introduced to Axis cameras in 2011 it was a game-changer. The downside of IR is that monochrome images make the identification of individuals difficult. The use of infrared (IR) lighting, which provides black and white images in darkness helped to some extent. As all cameras need light to create an image, the less light the darker and noisier the image. ![]() Low light surveillance – the current marketįootage in low light was once a massive issue for around-the-clock surveillance. ![]() The claims are that Lightfinder 2.0 provides:Īs most cameras now have some way of providing usable night images how impressive is Lightfinder 2.0 in this context? Lightfinder technology is geared around providing full colour HD video, even in near darkness. ![]() This was slipped in quietly as a feature, but nevertheless intrigued us. In May this year Axis launched some new cameras which contained Lightfinder 2.0. Lightfinder 2.0 – what is it and what difference does it make? ![]()
