Just a thought
a local clinic / hospital has just installed CCTV system and their
outside roof mounted PTZ cameras are all mounted on extended pendent mounts.
each of the 4 corners has a pendent on a 10' pole the view is great.Â
each one can see the roof, 2 sides of the building and all out in the
parking lots.
being about 4-5 feet above the edging of the roof, the cameras can see
each others..
I'd love to see them but alas I didn't do the job..

<br>
I have a project that involves getting a view of a roof. The
problem is that the roof is the only place for the camera to
be mounted and getting the right view is a challenge. So I was
wondering if a convex mirror were mounted on a light pole and
zoom in on the convex mirror would provide the necessary view.
<br>
<br>
Now I know physically and technically it is possible. What I
don't know are what are the challenges or unknown problems
involved in setting this up.
<br>
<br>
The camera distance to the convex mirror will be about 60' and
I will need at least a 60mm lens to zoom in on the mirror.
<br>
<br>
Anyone here ever done this and what are the difficulties
experienced??
<br>
<br>
Thanks in advance for any insight.

Actually the customers desire for the view of the roof is to
ensure
<br>
or verify that the ice melt wiring that was installed is doing its
job.
<br>
<br>
I kid you not!!!! Big concerns that snow and I build up will
happen
<br>
and it needs to be monitored by staff so that proper action can
<br>
be taken in a timely fashion.
<br>
<br>
It is seriously being discussed and requested and in order to
<br>
get a view from the roof I would need two cameras and special
<br>
mounting brackets to get a proper view.
<br>
<br>
Thanks for the tip the IR possible issue. Night vision may not be
an
<br>
issue since there are external lights. I need to check on that.
<br>
<br>
I was thinking the stability may be an issue as well. Although
<br>
only in high wind condition.
<br>
<br>
Thanks for the input and the smile.
