nigh vision camera question

[cj454]

I have a night vision camera that is in isde looking out a window. At night the IR bounces back off the glass and makes the camera useless.
Is there a way to put a film or something on the window or the IR on the camera?

There is no off feature for this short of opening the camera and disconnecting the IR leds. This would ruin the camera and void the warranty.

So i was thinking there might be some sort of anti glare film or may be a flat cable i could use (this is BNC) and out it out side the window. I dont want to drill into the window frame etc. but a cable would keep the window from closing.

thoughts?

I don't think there is much you can do about the windows itself, but have you possibly considered masking off the IR LED's with say black tape or maybe a heavy black stock paper (leaving a small hole for the camera itself?

FYI, I'm guessing the IR LED's probably also reflect off of the camera's lens to some extent.

do you have a model number?

most IR cams have a black foam rubber gasket that goes between the lens and the glass so IR leak is not a problem... you could use the material from the bottom of a mousepad and cut a circle gasket and place it between window glass and the lens so the reflection would be outside the lenses view. Hmm, if it is a double paned window, reflection might still be an issue ....

Also, you could probably take the leds off line by opening the case and disconnecting the wire (usually a 2 conductor wire coming from the led assembly going to the circuit board. ) If you don't feel comfortable doing that, then next would be Gaffers tape placed over leds and cut a hole to let lens see through. (as mentioned) If you can, I would remove the led part and place it in a different location so you don't get the glare. (run a wire to alternate location and splice it in.) If you can get the same plug connectors, you could build a custom wire so no splice would be necessary. It would take some care to not make it look jerry rigged. With the right supplies, you could make a pretty good looking set-up. (I don't know how handy you are or care to be)


My 2 cents anyway...

thaxs to all that posted. my concern is voiding the warranty so I did not want to open the camera up.
I had considered the tape but then it would be black and white during the day. but that may be the easiest thing to do is cover the leds up.

Maybe... you should try the opposite.

Instead of taping over the LEDs the cameras uses at night.... maybe you could add your own LED over the cameras photocell... which would tell the camera it's daylight.

Was this camera a new purchase? Maybe you should send it back and purchase a low lux camera that doesn't use infrared LEDs in the first place. Even without the LEDs bouncing off the window you might get some reflection at night so plan B would be to drill a hole and run the cable outside...

I cannot do this i twas a q-see system with 8 cameras in the set. It works great but I just dont have the desire to climb all over my attic and drill holes right now. to many other projects to work on first. so I was looking for a temp fix. They may end up outside at some point.

I think if you're careful in the taping process, you could tape over the LEDs and not cover the sensor that tells the camera that it's dark.... you can usually identify the sensor pretty easily - it has squiggly lines!

Is this from a Costco Q-see system? What do you think about it? I am thinking about purchasing one.

I like the system very much. However it is missing a few options i would like to see.
one bing the ability to turn off the night vision another being able to limit which users can see what cameras they can see.
also you cannot remotely admin user accounts on the system.

As for the taping I tried that with black electrical tape and a piece of paper overlaid over it. Still did not help. I still got a reflection. I may have cut the hole to big for the sensor so got some bleed threw of the LED.

Have you tried putting the camera flush with the glass? Although you may not be able to get the angle you want...

 

[JeffCharger]

as said, the lens of the camera has a foam ring that protects it from glare. What if you put another foam ring between the glass front of the camera and the glass of the window?

 

[cj454]

i have tried to flush mount the camera and it still glairs back.
and yes the angle would be off even if this did work.

as for the foam ring no i do not have one on the camera. not sure what you are talking about.

Thanx for the idea.

well, if the cable through the window is the problem, they make flat cables specifically for passing through windows - like this one http://www.summitsource.com/flat-coaxial-r...lx8-p-6984.html

they're all over the place ranging in price from $0.88 - $7. Then attach BNC to F adapters. The power wire should be too small to matter so you should be fine there. That'd hopefully get the camera outside without drilling.
