I bought my dad a trail cam for Christmas. Apparently there are 2 main types, low glow and no glow. Basically any no glow model should suffice.
Tbh, I haven't tested it, but this Amazon model claims to be no glow. Its the 940nm leds that make it no glow. The 850nm leds are closer to.human visible range.
