DC12V AC24V CLASS 2 ONLY For USA ISOLATED POWER ONLY For EUROPE INPUT OUTPUT ALARM PUSH POWER MONITOR OUT 10BASE-T/100BASE-TX For USA DO NOT CONNECT TO THE TELEPHONE NETWORK Push Cable Specifications 50 m max. UL1007, UL1015 or equivalent AWG #22 to AWG #18 or equivalent Caution Due to external noise, the camera may not work properly even if the length of the cable is less than 50 m. If this occurs, use a shielded cable or keep the cable away from the noise source. Alarm Input Terminal This terminal is for connecting with a sensor, infrared, door or metallic, or a manual switch.
