TatonkaII, most everyone uses meats of some sort or another, from road kill, butcher scraps, table scraps etc., and even fruits as well as dry dog food. I guess it's a matter of what you can come up with. It takes a lot of bait to keep a site going, and if you are to be successful, you need to keep it baited. For me, bait is hard to come by, so I generally use small chunks tossed around the site, but I love to take advantage of a road kill deer carcass when I can get one.
As to motion sensors, that is a must if you hunt at night. I first began trying to look through a Gen 1 NV scope every few minutes while sitting in a ground blind. I learned in short order that doesn't work. You need a sensor that will alert you to something on the bait, and you need a place you can rest comfortably throughout the night.
Several guys shoot from their home to a bait pile. I can't do that so I purchased a small storage building that I turned into a mini cabin. I stay the night down at the farm / cabin once a coyote hits the bait. I have a nice warm bunk and can fix coffee and something to eat. That's the way I do it. Others may do differently.
Some guys spot with red lights once the alarm sounds. Others use night vision of one form or another. I started out with a Gen 1 scope and used IR lights mounted at the bait site that were remote controlled on and off. Trail cameras can also provide necessary IR when tripped. I have since put together a home-made night vision outfit that works extremely well at a bait site, and it's cheap - somewhere around $200 to build not counting an IR illuminator.
There's a learning curve involved sometimes with bait hunting. I have been through many different trials before getting it to work well. Now I have it fine tuned. It's just a matter of being at the cabin when a coyote shows up. That in and of itself is not always an easy task, since even though a coyote may hit the bait one night, that doesn't mean it will return the next, though many times it does.
Good luck.
