How to Connect Audio In Device 
The camera comes with an audio jack where an audio input device, such as a microphone with a 
built-in amplifier, can be connected. The audio-in jack is covered by a rubber protection.   
WARNING: Do not remove this rubber protection if the audio-in jack will not be used to avoid 
water or dust from entering the jack. 
To connect an audio input device, do the following: 
1.  Pull to remove the rubber protection. 
2.  Connect the audio input device. 
NOTE: The microphone must have a built-in amplifier. Connecting an ordinary microphone 
will dwarf sounds and will result in inaudible recording. 
3.  If the camera is installed outdoors, be sure to wrap the audio connectors with Waterproof 
Tape (can be purchased in hardware stores). 
DISCLAIMER: ACTi will not be responsible for camera damage due by water leakage 
caused by improper waterproofing of cables.
