Alarm connection and installation
Connect the alarm cables according to the sketch below. Once distinguishing the alarm signal,
the speed dome will immediately act as per the process set before, it will start the camera,
display the image of the alarm zone on the monitor, adjust the speed dome at the alarm
point, and monitor the preset position, record what happens at the alarm zone as soon as
possible. Connection of the alarm cables as the sketch below:
Attention:
a. Alarm input must be ON/OFF input signal, any other types of input signal(such as
power voltage etc) is possible to damage the unit. When there is alarm signal from multi
channels, the unit will response to them one by one, the interval is 2 seconds.
b. Once there is alarm signal coming in, the unit will not response to “Scan” , “Cruising”
etc functions. Manual operation is needed to restore “Scan” , “Cruising” etc functions.
c. No matter the alarm function is opened or closed, alarm output always responds. For
example, if the alarm function of the unit is not open, when the unit distinguish alarm
signal, the unit will not be adjusted to corresponding preset position, but the alarm output
still responds.
d. The operation method for alarm function is: through previewing the No. 147 preset
position to open alarm function, through previewing No. 148 preset position to close
alarm function.
