L/L - INT Security Camera Switch SettingThis CCTV Security Camera switch selects the camera synchronization mode: internal synchronization mode (INT) or line-lock mode (LL).
L/L: Sets it to line-lock mode. This makes the vertical phase of the camera’s video signal match the phase of the AC power.
INT: Sets the internal sync to 2:1 interlaced.
