Dual Glass Technology Explained
How can our IP Webcam kits help your Business
Dual Glass Technology for CCTV cameras and webcams is quite a simple invention, but it has provided the cure for IR reflection on cameras with
built in IR led's for night vision.

When All In One cameras first came about - that is
day night cameras with built in IR LED's, they had
the IR LED's behind the front camera glass along
with the lens which was butted right up against the
glass with a rubber seal around it to prevent the IR
light from reflecting back into the lens.
This works great - until dirt and dust collect on the
front of the glass. When this happend, the IR light
would hit the dirt and then be relected back through
the thickness of the glass ultimately ending up
shining into the lens.
This is completely cured by using dual glass
technology. What this means is that the LED's are
still behind the main protective glass front of the
camera, but the lens is contained in a sealed tube
with a glass front which protrudes through the front
glass of the camera about a milimetre or so. This is
environmentally sealed and is completely
weatherproof to IP66 with Camsecure cameras.
This has the effect of totally isolating the lens from
the IR LED's so no light can be reflected through the
glass and into the lens if dirt builds up on it.
This is a simple and excellent solution to the
problem and is now used on all Camsecure "all in
one" CCTV cameras, IP cameras and Webcams.
This does not cure the Spider problem though and a
web spun in front of the camera will ,be invisible
during the day but will glow radiantly at night when
bombarded with IR light.

Lens protrudes through main glass window in turn protected by its own glass
Lens is in front of the LED's and completely isolated so there is no chance of IR
reflection back into it through the thickness of tthe glass if the LED glass gets dirty
