Myth of 170 degree view
Question from
customer:
Your competitor sells
similar camera with 1.7mm lens and stated that their camera viewing
angle is 170 degree. How come your 1.7mm camera has a much smaller
viewing angle of 136 degree?
Answer:
This is one of those misinformation which our competitor
never truly discloses to their customer. Here is the fact.
Viewing angle can refer to either of
these angles shown in the diagram below.
 |
 |
| 1. Side to Side Viewing Angle
(Let's call it SS Angle) |
2. Corner to Corner Viewing
Angle (Let's call it CC Angle) |
Our competitor may be referring to the
CC angle and not the SS angle. Our 136 degree view refers to SS
angle.
And not all 1.7mm camera can achieve 136
degree. We have seen cameras with 1.7mm lens that has only 90
degree view. How could that happen? It happens because the
camera uses cheap CCD chip that cannot handle such a wide angle view.
So watch what you are buying.
So the next time when a seller tells
you that their 1.7mm camera can achieve a viewing angle of 170 degree,
make sure you know what he is talking about.
