Re: IR Illuminators



Actually I have two Speeddomes in operation, one Ultra V is inside, looking
inside at the entire first floor.  http://www.odoms.net/speeddome/  I can
see almost everything on the first floor looking 360 degrees with that
camera.  That is so I can keep an eye on things (cats, people, doors from
work).
http://www.odoms.net/speeddome2/cameras.html   I have a second Speeddome, an
Ultra VII, in a window upstairs in my husband's office.  Mainly it is to
look outside, but I can also look in to see if my husband is on his computer
so I can email him from work.  It would be in an outdoor enclosure outside,
but we haven't gotten brave enough to tackle that job yet.  Plus hubby
doesn't want our house to look like a prison.  I also have fixed infrared
cameras outside at the front door, back door, and side yard at the breaker
box.  I also have a fixed infrared looking at the kitchen, opposite where
the Speeddome home position points.  The illuminator I bought on ebay is not
attached to anything at the moment.  I bought it on a whim thinking that I
could illuminate the area where the downstairs Speeddome points, at that
time, not fully understanding IR filtering.  I was testing the illuminator
in my office, moving it around, where I have an Axis 213 and an old PTZ-2
just for fun.  The Axis goes to 1.0 lux in day mode, complete darkness in IR
mode, but it's a manual switch.  The PTZ-2 is only good to 7.0 lux.  I can
barely see any illumination with the Axis, and absolutely none with the
PTZ-2.  If I put the illuminator out where the Speeddome is, same deal, only
see a very slight amount of light (speeddome goes to 1.5 lux).  I didn't
know the best spot for the illuminator, so I just moved it all around.

I need Pan/Tilt/Zoom and 360.  I replaced a fixed infrared with the
speeddome.  I could buy the day/night speeddome, but they don't show up on
ebay very often.  I don't want to pay full price.  Anybody got a used one
for a decent price?
http://www.americandynamics.net/products/speeddome_ultra8.aspx  and in white
is preferable, cause this thing sticks out like a sore thumb.  :-)  We would
recess it, but the ideal spot is just where a huge beam is located.

I think a sensor driven light is the answer to this problem, as Doug
suggested.  Don't anyone waste any more effort on this.  Thanks.
