Image brightness and sharpness may vary according to the distance between the camera and the ST-CCTV-VBAC16. A potentiometer and set of DIP switches are assigned to each of the ST-CCTV-VBAC16’s channels. The potentiometer is used to adjust “brightness” while the DIP switches adjust “sharpness”.
Video image appears scrambled – (i) Check to be sure all UTP wiring connections and polarities are consistent at each device and the ST-CCTV-VBAC16 RJ45 input(s). b. Video image has some ripples – This may be caused by electro-magnetic interference.
