Secrets to Perfect
Surveillance Design
By Stephen Bond, Wach1design, Perfecting Surveillance
Why are we giving away our secrets? We are dedicated to
perfecting surveillance. We are confident this article will find
its way to those seeking the best surveillance design for their
project and they will contact us
Visual acuity terms such as PPF, Pixels-Per-
Foot, Inspection, Identification, Recognition,
Observation, Detection and Monitoring are alien
terms to your clients.
So, stop talking…. let them experi-
ence the meaning!
To make this extremely simple, Wach1design
developed the HEED Index.
The index allows your clients to see, with their
own eyes, at their own location, without using a
security camera, what 500-pixels-per-foot, (In-
spection-level detail) looks like.
It also lets them see what 3-pixels-per-foot,
(Monitoring-level detail) looks like. In all, Wach-
1design’s HEED Index allows them to experience
what 20-different visual acuity terms look like.
The HEED Index ensures
engineers, consultants, in-
tegrators and end-users
are all speaking the same
language when discussing
security cameras and sur-
veillance design because
it removes the ambiguity
from the discussion.
The calculations used to
create the Heed Index are
similar to the ones used
by Steve Jobs when Apple
was developing the Retina
display for the iPhone.
4-Step Process:
HEED stands for Human Eye Equivalent Dis-
tance.
Step 1 – Print a copy of the
HEED Index. Printing it on
card-stock or laminating it
will make it easier to work with outdoors when it
is windy.
