LIGHTFINDER TECHNOLOGY
A day and night network camera can deliver excellent
color images during the day. As night falls and light
fades, the camera can automatically switch to night
mode to make use of near infrared (IR) light to continue
to deliver video. However, the images produced in low
light condition are typically in black and white.
But with the Lightnder technology Axis has mastered
the art of low light video. This is the result of a careful
choice of CMOS sensor with the appropriate lens, to-
gether with the elaboration of the image data coming
from the combination of sensor and lens. The fusion of
these factors – sensor, lens, in-house chip development
and knowledge in image processing – provides the out-
standing performance of this technology.
A network camera incorporating Lightnder technolo-
gy will thus oer better resolution and more lifelike
colors in low-light conditions than any analog camera
on the market. Furthermore, these advantages come
without compromising other important features of
network cameras, such as progressive scan and video
intelligence analysis.
Network cameras with Lightnder technology are the
perfect solution for indoor and outdoor surveillance in
low-light conditions, especially where users require
color information in the video for recognition and
identication purposes.
EDGE STORAGE
Edge storage is a concept in Axis network cameras and
video encoders that allow them to record video directly
to a storage device such as an SD/SDHC card, creating
more robust and exible video surveillance systems.
Using edge storage, it is possible to record video locally
when the central system is not available, or continu-
ously record in parallel.
When used together with video management software
(VMS), missing video clips resulting from, for instance,
network disruptions, can later be retrieved and merged
with the central storage, thereby providing uninter-
rupted video recordings. Additionally, edge storage can
improve video analysis for systems with low network
bandwidth and it can be used to manage recordings in
remote locations or installations where there is inter-
mittent or no network availability.
