I have a truth cam 46 and it takes terrible night pictures, but i dont get the black images. But i found this on primos website from an employee
"I'm sorry to hear you are not getting satisfactory operation out of the cameras at night. As per a previous suggestion, lower the LED count on the settings to 25 LEDs. Except for extreme far range shots, you should get good lighting (actually better if subjects are very close) and the batteries should last nearly twice as long (if not longer)." I have not tried it as of yet
There is only a 1 year exchange warranty so if still in warranty go submit a ticket on their website. If older they wont repair it and you have to contact customer service to get a "reduced rate" for a refurb.
Hope this helps
