Make sure camera has good WDR or backlight compensation. Many cameras can't handle the indoor/outdoor contrast and overexposure when the door is opened and it's bright outside.
If it's in a garage, not out in weather, and you're trying to stay under $100 a Dahua K42A would probably work out. Keep in mind that it does have a wide angle lens so to get a positive ID shot the subject needs to be within 10 feet or so of the camera.

I have two of those in my garage, both in 2.8MM. They do ok. I have not really tried to dial these in. They give a nice overview of the inside of the garage, but they are not as good as more expensive cams when it comes to motion. See the pics below. Back lighting is a problem. These show with door open, closed with IR, and closed with light on.
In the past there have been some good deals on some Amcrest Cameras that some have used indoors ( example their 5MP turret ) which is an affordable option, however the body iirc is plastic
Also worth considering in places you need a less visible camera would be the mini-dome wedge .. I like this face level at my doors ..
