Another suggestion is to view pictures or videos submitted on various trail camera websites. Most will show the make of camera and possibly the series. If you find something you ware satisfied with, you could further ask for information on that brand, series, performance etc.
$150. to $200. will get you a good quality camera. Also check the manufactures. Some (Bushnell) offers a two year warranty while others only offer one year. Good luck in your choice.
