Caution:
A READILY ACCESSIBLE DISCONNECT DEVICE SHALL BE INCORPORATED TO THE
EQUIPMENT POWERED BY 12 V DC POWER SUPPLY.
ONLY CONNECT 12 V DC CLASS 2 POWER SUPPLY (UL 1310/CSA 223) or LIMITED
POWER SOURCE (IEC/EN/UL/CSA 60950-1).
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 bottom side of this unit) regarding power source and power consumption.
Connect a microphone or the line out of an external device using a stereo mini plug (ø3.5 mm).
Input impedance: Approx. 2 kΩ (unbalanced)
Recommended cable length: Less than 1 m {3.28 feet} (for microphone input)
Less than 10 m {32.8 feet} (for line 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)
Input level for the line input: Approx. –10 dBV
IMPORTANT:
Connect/disconnect the audio cables and turn on the power of the camera after turning off
the power of the audio output devices. Otherwise, loud noise may be heard from the speaker.
Make sure that the stereo mini plug is connected to this cable. When a monaural mini plug is
connected, audio may not be heard.
When connecting a monaural speaker with amplifier, use a locally procured conversion cable
(mono-stereo).
