IR led a dead giveaway?

I badly want to acquire a Generation 1+ unit that is under 800 bucks for airsoft. I'm sure there are lots of options but I have shot out people using NvGs due to their red IR led giving their position away. Are there any night-vision devices that have a LED that is harder to spot that fit my budget? Or should I wait a year to get the money for a higher end system.

Thanks in advance! and post if you want any other questions made clear

Your opponent will see any IR from your night vision device. Shutting it off is the only way to not identify yourself.
