On-board LED light
The on-board LED light is meant specifically for improving reflective marker tracking. The light is NOT
meant to provide ambient lighting in low-light conditions. The keypad on the rear of the Ninox camera
provides three different brightness levels (low, medium, high). The brightness can be adjusted to
provide reflection from motion markers depending on ambient light conditions. However, to
automatically have the LED light turn on at the start of the measurement, one must select the LED light
option within the configuration (See Step 2 of Section 6.1)

Video Compression
All video files for the Ninox cameras are saved in a compressed format. The video compression occurs
at two different levels, real-time and post-process.

time compression - occurs as the video is streamed to the host computer. The video is
compressed real-time into m-jpeg format.

Post----process compression
process compression
process compression
process compression - can be executed after a record has been saved. The video will be further
compressed into an mpeg4 format to reduce file size. The post-process compression will reduce the
initial file size approximately 5-10X.

File Size
Due to the high frame rate and resolution capabilities of the Ninox cameras, large file sizes will be
created when recording. The following numbers are approximations of the file size per minute that can
be expected. The values listed are for a single camera.
