Darknight, here is a link to a 940nm spotlight I use at my bait site.
https://www.amazon.com/CMVision-IR130-94...20&sr=8-18MThis light does not give off any visible glow that I can see. Coyotes pay no attention to it. I have mine mounted on a tall 4x4 post that is 25 yards from the bait site. It is DC powered but comes with an AC adapter. I use it differently than you plan. I control it remotely from the cabin via a remote controlled DC switch, available on Amazon and Ebay. The spotlight doesn’t have a great illumination throw like an 850nm does, but it’s more than adequate for shooting, and should enhance your video camera. Mounting the light near the bait site is necessary. A 12 volt battery is required to operate the light. I use a small lawn mower type battery. I also have an 850nm spotlight like the one DoubleUp uses, but rarely do I use it. It does give off the red glow, though.
For constant use with a trail camera or video camera you will need a deep cycle battery and have to keep it charged unless you will mount the light near a 110 outlet.
Here is the DC switch I use. There are various ones available.
