[. . . ] Set the focus of lens so that the distance at the lens is close to infinity but not to exact infinity position. 7. Loosen Back focus Adjustment Lock Screw one~two turns on the camera with industrial "+" driver Rotate Back Focus Adjustment until the optimum focus is achieved. Tighten Back focus Adjustment Lock Screw again. Trim the focus precisely at lens if necessary. Setting for lenses with a variable focal distance (zoom) If the focus changes as the focal distance changes, please proceed as follows. Point the camera at an object with sufficient contrast at a distance of approximately 2 meters. Set the maximum focal distance (Tele) at the lens 4. Set the optimum focus with the focus ring 5. Set the smallest focal distance (wide angle) 6. Loosen Back focus Adjustment Lock Screw one~two turns on the camera with the industrial "+" driver 7. Adjust Back Focus Adjustment until the optimum focus is achieved. Steps 3, 4, 5 and 7 may be needed to repeat several times to obtain the best results 8. Tighten Back focus Adjustment Lock Screw again 5. 3. Installation The camera has a 1/4" thread insert on its top and bottom side for mounting the camera to a tripod or the wall or ceiling with a corresponding mount. 5. 4 Commissioning · Connect the power to the camera firstly · Plug the power adaptor to the mains supply secondly · Power indicator LED will be lit · The camera is ready for operation 5. 5. Power Supply Connections Camera can work with either 12VDC or 24VAC, dual voltage power. It does NOT require the polarity-matched connection for 12VDC supply. Primary and secondary grounds are completely isolated to avoid the possible ground-loop problems. Its excellently wide operating voltage range of 10. 5V-30V for DC and 12-28. 8V for AC gives an extra flexibility at the installation. 6. Start up When the camera is powered properly, it starts up with initializing the internal parameters and the filter switch mechanism. The filter switch unit repeats IN and OUT two times at each power up and just after RESTORE FACTORY SETTINGS. 8 VTC-C750WDR 7.
