Be sure to connect grounding lead to the GND terminal. Cautions: 1. Connect this to a 24V AC class 2 power supply only. 2. To prevent fire or shock hazard, the UL listed wire VW-1, style 1007 should be used for the cable for AC 24V Input Terminal. ELC (Electronic Light Control) In this mode a continuously variable electronic shutter is employed to automatically control exposure times in the CCD Image Sensor, according to the incoming light level. With this mode selected, fixed or manual iris lens can be used instead of an ALC type lens. Caution: Under certain unique lighting conditions, the following may appear: • Strong smear and/or blooming on high light objects such as spot lights or windows. • Noticeable flicker on the picture. -6- CONNECTIONS Power Source • WV-BP110 Connect the AC.

Video Cable 1. It is recommended to use a video monitor whose resolution is at least equal to the camera's. 2. Terminate the camera output with 75-ohm resistor at the furthest end of its cable run. • It is recommended to use 75-ohm coaxial cable. • Always set the last monitor's termination switch to 75 ohms, and set the termination switches of intermediate monitors to high impedance (Hi-Z) position. Monitor Monitor • The maximum extensible coaxial cabie length between the camera and the monitor is shown in the table 1. Since cable quality varies among manufactures, verify video quality before final installation if maximum lengths are to be used. Table 1 Type of coaxial cable RG-59/U (3C-2V) RG-6U (5C-2V) RG-11/U (7C-2V) RG-15/U (10C-2V) Recommended maximum cable length (ft) 625 1,650 1,980 2,640 (m) 250 500 600 aoo Wiring precautions: • Do not bend coaxial cable into a curve whose radius is smaller than 10 times the cables diameter. • Never staple the cabte-not even with circular staples. Mismatching will occur. • Never crush or pinch the cable. All of these will change the impedance of the cable and cause poor picture quality. LENSES 1. Selection of Lens
