There are lots of cheaper cameras. There are no other cameras close to that price range that perform like that one does. If the budget is anywhere close to 150, then definitely spring the extra 20 bucks for that one. If not, then look for some of the cheaper Dahua turrets in the $70 range on AliExpress but make sure that you budget for a strong external IR Illuminator, power supply, and wiring for each camera to try and bring their performance at night somewhere close to the Starlight turret at 170. Also make sure that you properly match the lens length to the application because the cheap ones are not varifocal.
