JVC VN-C3WU Instruction manual on the VN-C3WU Vnetworks camera (938,203 bytes, - Page 41

Color balance is unsatisfactory. Image size and position change spontaneously. Focus is not accurate. • Try changing the Camera Auto/Manual setting in the VN-C3WU Settings Page from Auto to Manual, and then back to Auto again. When changing between scenes with different light sources (for example, when moving from outdoors with sunlight to indoors with fluorescent lighting), there may be a slight delay before the automatic tracking white balance function starts to operate. Depending on the subject, the color balance may appear to change slightly. This is not a malfunction. This product uses auto white balance. When most of a subject is red, blue-green areas may appear bluish; blue areas may appear orange; and yellow areas may appear bluepurple. In such cases, use the color balance image quality setting to adjust the color matching. This sometimes appears to be the case when multiple operators and administrators have access to one VN-C3WU unit and change the settings because the last settings made will still be in effect for the next user. The autofocus may not be accurate in dark places and in locations without features, such as a wall, etc. In such cases, adjust the focus manually. Focus may be slightly off when adjusted manually at the TELE setting. This is not a malfunction. Due to its principle of operation, autofocus is difficult with striped subjects. 41
