IMPORTANT!
1. Before using the Focus Assist function, the camera should have been stably installed
and the camera's shooting direction and view angle must be secured for a stable view.
If the view is altered, you should fine-tune the camera's zoom and focus again by
turning off and restarting the function.
2. Instead of a BNC connector, the camera is equipped with an AV output phone-jack that
serves the same purpose for initial video adjustment. You may use the AV output to
connect to a portable monitor such as a mini-DVR.
