Since you mentioned Cam Pan v3, I want to make sure you’re aware that Bulb Cam—despite its passing superficial resemblance to Cam Pan v3—does not have motorized pan and tilt:
These are essentially stationary cameras in the same way that something like a non-pan Cam v3 or Cam v4 would be: You adjust the position manually and then the camera remains in that position once you set it.
