My first DataCam is wired from the speaker wires to the relay. I remember someone stating that it could also be wired off of pin 3 on the small IC chip. I have my RS sensor set to alarm mode. This gives me a 30 sec delay between pictures. I do not have a problem with multiple pictures being taken during the 30 seconds. I did some testing off of pin 3 and it seems that it provides just over 5 volts for the 30 seconds. This would provide a 30 second delay without the singing of the relay. Did anyone try to wire the relay off of pin 3 on the small IC chip. Thanks, Data.
