Zones of Coverage
There are four key zones of coverage. All camera lenses have to trade off focal length versus angle of view. This is
especially true for hemispheric fisheye lenses where the viewing angle is 180° in every direction. The fine detail and
high
‐
pixel count required for face recognition or license plate reading is limited to close
‐
up views, however there is a
very broad section of the view where detection and identification can occur.
3.4.1
Facial Recognition
(=< 5m / 15ft)
Faces will be clearly visible and well defined.
Example: a camera mounted at 3m/9ft high, within less than 5m/15ft of a doorway, the
camera view will be able to identify and recognise a person entering.
3.4.2
Facial Identification
(between 5m and
9m / 15ft and 27ft)
People and objects are identifiable based on clothing, make and model of a car, body type
and other criteria. At a counter or customer service desk, the identity of the customer is
verifiable.
A wall
‐
mounted camera works well for
close
‐
up views and low
‐
angle shots.
The area of coverage can be enormous
for a camera that is mounted high above
the ground. This one is 10 stories high, yet
cars and people on the street below are
still visible.
