Note for Sealing the Bullet Camera
To ensure that the camera performs its full capacity against water and
dust, adhere to the following guidelines when closing the Bullet Camera
cover:
1. Line up the dots
Tighten the camera cover until the dots on the cover and the body
line up as indicated below.
2. Make your own marks
For earlier models, you may not have dots on your camera. In this
case, make your own marks on the camera cover and the body to
note down the position.
