I'm having a bad run with electronics at the moment! Setup trail cam for pigs. At night, the images are just black apart from one which has two pairs of eyes staring straight at the camera. Can't tell if it's a pig or a possum doing an impressive photo bomb! Daytime photos are fine. Pretty sure the IR lights aren't firing. Had new batteries. It's a Campark T20 if that makes any difference. Any thoughts?
what mode is it in?
Photo+video, both photo and video are affected.
I have a cheapie camera I bought of the 1-day website. It freezes if it tries to video at night so I just use the photo function.
To test if infrared LED (Flash) is firing at night set up on the dark and use a cell phone camera looking at the LEDS - you should see a glow (cant see with naked eye if black flash out of spectrum of human eye) if not the fault could be that.
2nd if you look into the camera port you may see a slightly pinkish looking lenses, this is a day light color filter to give color to images etc... at night this IR filter should move out the way to allow the camera to pick up Infrared better. Sometimes these are mechanical moved other times cameras may not have one. This too can be faulty as its a moving part and requires signal to a electro magnet to move it. Check that this is operational. (pink covered in day and gone at night)
The way it knows to choose an IR or day photo is determined by a light sensor on the front of the camera. The camera looks for amount of light and if too low will stitch to the infrared (black and white) pictures and fire the Night LEDs. So be careful at night when using a torch or light source to test as you could fool it into thinking its day ha ha.
Forgot to say if the IR filter lense is the issue you can remove but day pictures will lack color and look more grey. easy fix for those who do not know how to repair electronics.
Try running it as just photo I have a Moultrie that won't do video at night.
Another way to test it is to look at it with a nv scope or spotter. When the flash triggers you will do see it allright.
OK, thanks everyone for your help. Photo only mode seemed to do the trick and "1 photo in series" was more reliable than multiple photos in series. I can see the LED flash coming on with my naked eye. Effective range is about an arms length, beyond that it's back to black nothingness. Is that normal for cheapo cameras?
I think my cheapo's quote 20m range (or was it 20 feet...).
I'll check if I can find the boxes.
My suspicion are the ir filter lens is stuck down (day mode) if ir leds flashing then it should at least make 5 metersQuote:

I'm going to take a screwdriver to it. Historically, this hasn't ended well for me, but not much to lose.
My theory on why mine freezes when trying to do video at night is that it is too much drain on the batteries, having to run the IR lights constantly for several seconds rather than just a flash.
I think you're right. Video is a bit much for some of the cheap cameras at night.Quote:

From your description it sounds like the ir bulbs are stuffed you should get about 10m range even with a cheap one, either that or the units sensor has drifted and is no longer responding to infra red light.Quote:

mine blinks on for a second or two when it takes the photo and is quite noticeable
might pay to check if the model is night capable, I havent seen one that isnt but you never know this might be the first
Yes, the LED lights/flash come on and it does work at night out to about an arm's length.Quote:

sounds like its taking the picture before or after they come on the camera should do arms length on its own
I say should but I dont know these things for sure
I've emailed Campark. It wasn't an expensive item, but annoying nonetheless.
