Bit-Reduce Technology
Innovative Bit-Reduce technology ensures low bit rates
and helps to stabilize networks. Bit-Reduce design is a
combination of:

•

Black Diamond Infrared illumination, which solves the

problem of failed compression at night caused by

image noise

•

Proprietary on-camera image processing, which sends

only the required image data down the network,

reducing bandwidth

•

More than twenty compression levels to help achieve

the right balance of file size and image quality for any

application

Bit-Reduce design is unique to the EX85, making it the
most advanced megapixel camera available today, not only
for imaging performance but also for its bandwidth
management capabilities.
Megapixel Technology
Megapixel cameras offer numerous advantages over
conventional cameras. Below is a partial list.

•

Greater resolution for outstanding image detail

•

Greater field of view, reducing the number of required

cameras

•

No need for PTZ, no moving parts, record everything

all-the-time

•

Lossless forensic zoom for post-event investigations

•

Enables optimal performance of video detection and

video analytic software

•

Greater remote control over image acquisition

parameters

•

Easily scalable and expandable, with lower installation

and long-term ownership costs
