Others ⅷ This camera comes with a built-in AGC circuit. Setting AGC to AMidB, AHighB or ASuperB increases the sensitivity of a dark image, and the screen may appear grainy. This is not a malfunction. ⅷ When this camera is used with the white balance set to AATWB (Auto Tracking White Balance), the color tone of some objects may differ slightly from the actual color due to the principle of the automatic tracking white balance circuit. This is not a malfunction. ⅷ If a high brightness subject (such as a lamp) is shot, vertical lines may appear in the image displayed on the screen (smear), or bleeding may appear around the bright subject (blooming). These phenomena are characteristics of the CCD, and are not caused by malfunction of the camera. ⅷ For regions with a commercial power supply frequency of 50 Hz, switch to the Flickerless mode during use under fluorescent lights (excluding inverter lighting equipment) to prevent flickers. ⅷ When switching between color and blackand-white images in the B&W mode, the brighter area on the screen is emphasized, which may reduce the visibility. However, this is not a malfunction. ⅷ When the electronic sensitivity enhancement feature is enabled, the screen may appear grainy and more white spots may appear as the sensitivity is increased. However, this is not a malfunction. ⅷ If the power supply voltage is momentarily cut off or reduced due to lightning or turning on of the air conditioner's power, the image may be disrupted or noise interference may occur. ⅷ The rotation angle of this camera is increased to enable installation at a wider variety of locations. When the zoom of the lens is at the wide end, and tilted at an angle close to ±80°, a part of the camera may come into view on the screen depending on the rotation angle. When this occurs, adjust the field angle accordingly. ⅷ When using multicast, make use of an IGMPv2-compliant network switch. ⅷ Power can be supplied to this camera either by using PoE or connecting to an AC 24 V power supply. Make sure that power is supplied using only one of the above methods at any one time. Connecting simultaneously using the power cable and to PoE via a LAN cable may cause the camera to break down or malfunction. ⅷ Some hubs/switches of products that are equipped with intelligent features may include a broadcast/multicast suppression function. Viewing of multicast images on this product may fail if this function is enabled. ⅷ During viewing using the integrated viewer, the video and audio sound may appear outof-sync. This is not a malfunction. ⅷ It is recommended to use shielded LAN cables, shielded alarm cables and shielded audio cables for connection with this product. The safety and reliability of this product has been checked by using shielded cables. 5
