If your alarm panel outputs a high signal then set your DVR to receive a high signal.
If your alarm panel outputs a low signal then set your DVR to receive a low signal.

ALARM
OFF / HIGH / LOW High = 12 volts (or check your alarm panel manual) Low = Ground, or short.
Test your alarm panel with a meter. How does your panel work? If it triggers an event will it create a short, or will it output 12 volts? Based on this answer is how you would set up the DVR to respond to your alarm panel.
When your doors and windows are shut, and locked, then the alarm panel receives a low or a short signal from the contacts to tell the alarm panel that everything is safe, and secure.
If you were to have the alarm panel trigger a "siren", and / or a strobe then you will be using a 12 volt output from the alarm panel. When there is no alarm then there is no voltage going to the strobe, and the siren. You could tie this in to the DVR, and set the DVR to the HIGH setting. See output 2 from Sample Alarm System Wiring (ELK M1)
Perhaps you can use a relay to change the alarm panel output to the kind of signal that you need?
We do not recommend that you set up the system to have the DVR trigger an alert to the alarm panel. You may get false alarms causing the police to show up, and charging you expensive false alarm charges.
WARNING! SOME CITY POLICE DEPTS HAVE STOPPED RESPONDING TO ALARM CALLS DUE TO FALSE ALARMS.
VIDEO VERIFICATION FROM YOUR ALARM COMPANY WILL ACTUALLY RAISE THE ALARM CALL TO A PRIORITY RESPOND CALL.
Check your local police policy regarding burglar alarm calls.
You can set up your DVR to detect motion from the cameras, and then have the DVR trigger a strobe light, and a sounding device whether it is a soft tone device, or a screaming siren.
Check the output of pins 7 to pin 15 (COM = common), or pin 8 to pin 15 (COM). You will want to have a normally open connection between the output, and pin 15 the common connection. When motion is detected then you will want the ouput to create a short between the pin output, and the COM.
Take a power supply of 12 volts DC (Check your products listing for your country) and connect one power wire to the strobe light, and then connect the other side of the strobe light to a siren, and then connect the other side of the siren to the DVR, and then connect the other side of the DVR to the other side of the power supply. When the DVR closes the circuit, then the siren, and the strobe should work.
THE FIGURE BELOW IS A PICTURE THAT I STOLE OFF THE INTERNET.
It is not a perfect picture, but it will do. Ignore the writing attached to the picture.
The red lines will represent an output from an alarm panel. The switch, and the 12 volt dc, are located inside of an alarm panel, and the pins represent the camera trigger of a DVR.
The Blue lines represent the DVR output that allows an external voltage to trigger a strobe light, or a siren, or both.
