ONLY CONNECT 12 V DC CLASS 2 POWER SUPPLY (UL 1310/CSA 223) or LIMITED
POWER SOURCE (IEC/EN/UL/CSA 60950-1).
Connect the output cable of the DC power supply to the power cable plug (accessory).
IMPORTANT:
Be sure to use the power cable plug (accessory) provided with this product.
Be sure to fully insert the power cable plug (accessory) into the 12 V DC power supply
terminal. Otherwise, it may damage the camera or cause malfunction.
When installing the camera, make sure that excessive force is not applied to the power cable.
Be sure to use an AC adaptor compliant with the Specifications (written in the indication label
on the top side of this unit) regarding power source and power consumption.

Recommended cable length: Less than 1 m {3.28 feet} (for microphone input)
Recommended microphone: Plug-in power type (locally procured)
Supply voltage: 2.5 V ±0.5 V
Recommended sensitivity of microphone: –48 dB ±3 dB (0 dB=1 V/Pa,1 kHz)
