The software also shows an actual photograph
captured by a security camera at, or close to, the
specified pixels-per-foot.
The photograph is not from the actual location,
but it gives you a pretty good idea of what you
can expect from the camera.
In my opinion, this seems more useful than
JVSG’s method of displaying a sample image.
My wish list for the IPVM software:
• Designate the different visual-acuity zones
within the viewshed.
• In other words, the triangle shows different
colors to designate Inspection - Monitoring
areas.
• JVSG does this and it is very helpful when
going over the design with a client.
• Self-adjusting visual-acuity ranges.
• If you select a 5MP camera, the ranges
are appropriate for that resolution camera.
• However, if you specify a 4K camera, the

more restrictive ranges apply for that cam-
era.
• Clients will expect more detailed images
from their 4K cameras.
• This setting would ensure that expectation
would be met.
• Ability to add walls or barriers so the camera
viewshed stops at natural boundaries.
• If you look at the football field on the JVSG
drawing you will see how this works.
• Notice in the IPVM drawing how it shows
the viewshed going outside the stadium.
• Ability to import .PNG and .JPG images over
the satellite image.
• This feature would also need to support
layers so you could import multiple floors
of blueprints of building interiors and place
them on the drawing.
• Perhaps they could work with MapTiler to
make this happen.
• This would also be helpful if you created
your own high-quality stitch with a drone.
• Many times, the image provided by
Google is lower resolution than you wish.
This would address those instances.
• Ability to group cameras into logical sets.
• This is useful for helping a client budget
for a phased camera roll-out.
• One example would be to create the fol-
lowing five groups: (1-Must Have), (2-High
Priority), (3-Very Useful), (4-Low Priority),
and (5-Not Needed).
