3. Advance Setting
3.1 Intercom-Advanced
Photoresistor: The setting is for night vision, when the
surrounding of 20A is very dark, infrared LED will turn on and
20A will turn to night mode. Photoresistor value relates to light
intensity and larger value mean that light intensity is smaller.
User can configure the upper and lower bound and when
photoresistor value is larger than upper bound, IF LED will
turn on. As contrast, when photoresistor value is smaller than
lower bound, infrared LED will turn off and device turns to
normal mode.
Tamper Alarm: 20A integrates internal gravity sensor for the
own security, and after enabling Tamper Alarm, if the gravity of
20A changes dramatically, the phone will alarm. Gravity
Sensor Threshold stands for sensitivity of sensor.
