Looking for a good one for around 100$ I heard of star light can you guys link me to a good one?
Welcome to IPCT!
That info can be found in the
Cliff Notes.
Matter of fact, you should read ALL of the
Wiki as there's more to it than "...a good one". There are different camera types (turret, dome, bullet, cube), different focal lengths and more.
What may suit my application may not be right for your application.
