Note:
In Detect interface, copy/paste function is only valid for the same type, which means user may
not copy a channel setup in video loss mode to tampering mode.
About Default function. Since detection channel and detection type may not be the same, system
can only restore default setup of current detect type. For example, if you click Default button at
the tampering interface, user may only restore default tampering setup. It is null for other detect
types.
System only enables tampering function during the period you set here. It is null for motion detect
or video loss type.
