Reason why you shouldnt use cameras with built in IR emitter

Post by jameswilson »

I thought id test one and this has been on the fron of my house for about 2 yrs now. I will never fit a combined IR and camera again. Fortunatly i have always advised against professionally but thought id try one due to the cost savings

James,

I have seen similar on my cams when I have made "homebrew IR illuminators". If possible, try to "point" the LEDs more away from the camera lens.

Most likely, your LEDs are shining too close the "eye".

its a bullet cam mate with built in ir leds. I always avoided them as cheap and nasty, but thought id give one a go.... wish i hadnt. If i could move the emitter away from the cam so the spiders, moths and other wildlife arnt attracted to it... i really would lol

Depends on the region. Here in Houston it is no problem. I am talking about experience from hundreds of cameras on my types of DVRs...

I found the inbuilt ir cluster LED's on the Gadspot to be utterly useless, creating so much lens flare nothing could be seen other than a white blur.

I never thought about it before your post, but I get alot of moths and spiders attracted to the built-in IR in my camera. Apparently they must "see" (or feel) the IR spectrum.

Perhaps place a brighter IR emitter somewhere nearby, connected the to to the equivalent of a fly zapper.

I have a few hundred cameras that disagree. :) How about test small, or pay for local experience? Or just ebay stuff and pay a Lot for local experience. :D

That's why I'm thinking slightly distant IR with a bug zapper.

I get alot of spiders at my house but they don't seem to be attracted to the IR's of my nightvision cameras at all.

It's very rare to see them crawl in front of my cameras. Once in awhile their spiderwebs do get in front of my camera. During they day time you don't see the webs but in night-vision mode they are visible . The webs don't block the view of the camera but they do set off the motion detection. When this happens I take a broom and brush the area around my camera.

Must just be uk spiders then. Maybe the IR on my cams are more visible. I dont think the spider can see it, well i have no idea, but the bugs its catching can so thats the reason. I have some great vids of spiders, moths, rain on webs etc. Cant see much through it and i need to clean it every 2 weeks. Im gonna take it down soon!
