[Alarm to SMS] 
This function requires an external GSM modem to send messages to mobile phones via SMS 
(Short Message Service). 
(1) Please refer to your GSM modem user manual for the physical connections. 
(2) Go to Serial Port setting in the System sub-menu. Choose GSM Modem on the 
COM port that connects to the GSM 
modem. 
(3) Back to this Alarm Notice sub-menu, and 
set the Baud Rate to be 9600 baud per 
second. (Note: If you fail to send SMS 
successfully, you may reduce the baud rate 
to 4800 or 2400 bps and try again.) 
(4) Key in the Subject of the alarm message (for example, DVR Alarm). 
(5) Add Alarm Notice: Click the icon Add. 
(6) Alarm Duration: The duration time can be from 1 minute to 1440 minutes (1 day). 
When the “Alarm” happens, the DVR system will send the alarm notice one time 
during the duration and do it again in next duration until the “Alarm Source” 
disappears. 
(7) Select alarm Source. Please refer to the definition of each alarm source. 
(8) Action: Click the icon “SMS” to enter the mobile phone number. You can enter three 
mobile phone numbers to be notified for a single alarm.
