Before you start:
Check the package contents and make sure that the device in the package is in good
condition and all the assembly parts are included.
Notes:
 Do not touch the bubble directly by hand. The image blurs otherwise.
 Do not power the speed dome up until the installation is finished. To ensure the
safety of personnel and equipment, all the installation steps should be done with
power supply off.
 Do not drag the speed dome with its waterproof cables; otherwise the waterproof
performance is affected.
