Home alarm system

Does anybody know how I can trigger with ZM's motion detection a home alarm system? For example something like the email being received and a large alarm being set off?
Would you suggest any alarm-related forums or places I should look for information and ideas?

Many thanks.

You can receive alarms from zmtrigger.pl (it's a telnet server), and act on those.

You can set a filter to activate a shell script.

There are likely other ways. I don't know how you would interface to the Alarm system, but if it has GPIO, then it should be easy.

Commercial home security systems, as opposed to highly proprietary home owner grade systems that require same brand sensors, can always be triggered with a simple contact closure. The panel (alarm system speak for the brains of the system) can then programmed to do pretty much anything you want from setting off an internal or external bell, siren, or strobe; or notifying the monitoring center (or not).

So you need something that can be triggered by a script. There are a number of boards or accessories that can do this. They are readily available for serial ports, usb ports, and as Bluetooth devices requiring no direct connection to the server, provided that it is Bluetooth equipped itself.. And they still sell relay boards that mount directly in standard desktop/rack-mount cases.

Search on "Linux relay board" to find some examples. Prices are all over the place with the industrial quality stuff being the most expensive. Other quality levels can be had for lower prices.

And don't forget to check eBay and Aliexpress for some real bargains available direct from China.

Interface zmeventserver and use MQTT to a Raspberry PI. You then can act on that MQTT message by driving a GPIO pin attached to your security system.
