What exactly is House Alarm?

It's an app that can be used to control your Paradox™ alarm system from your iPhone, iPad and iPod Touch. House Alarm can notify you when your alarm has been triggered.

I have some ideas for House Alarm.

We would love to hear from you! Visit us at uservoice to share your idea and vote for others.

What do I need to use House Alarm?

You need a Paradox™ alarm system installed with a IP100 or IP150 internet module.

Adding a new alarm system.


This is the dotted IP address (e.g. or the DNS name (e.g. of your IP Module. The Paradox™ Site ID is not supported and should not be used. You can use any dynamic DNS service.

Further explanation of the Address field

For those of us that don't know what an IP address or DNS name is - read on.

An IP address is a dotted number that identifies a device on a network. Your IP100/150 would have been setup with one these IP's. There are 2 types of IP's:

  1. External. With this IP you can connect to your alarm from the internet and on your home Wifi. (Recommended option)
  2. Internal. With this IP you can only connect to your alarm when on your home Wifi. Internal IP's usually start with 10.0 or 192.168.

Your IP100/150 is always setup with a Internal IP. Usually the only device on your network that has an External IP is your Wifi router. To connect to your alarm from anywhere you need to connect to the External IP address of your Wifi router and have the router forward the network packets to your IP100/150. To discover the External IP of your Wifi router open the website from any device on your home network. Although you can use the IP displayed by directly in the Address field of House Alarm there are still 2 problems:

  1. Your External IP address may change. Your internet service provider may allocate you a new IP whenever you connect to them.
  2. Your router will not automatically transfer network traffic from the internet to your IP100/150. In other words connecting with House Alarm from the Internet (i.e. a cellular connection) to the IP Address revealed by will get to your Wifi router but not to your IP100/150.

To rectify point 1 you need to use whats known as a Domain Name Service (DNS). A DNS supplies a friendly name such as When resolved by a DNS actually returns an IP address to connect to. There are a number of free services available such as, and These are whats known as Dynamic DNS Services. They are used to map your ever changing External IP to a friendly name such as All home Wifi routers come with built in support for these services. In your router settings look for "DDNS" or "Dynamic DNS Service". Select one and enter your account details (You will have to create a free account with one of these services). Once done your Wifi router will automatically update your chosen DDNS service every time your External IP changes. Now you can use your new DNS name such in the Address field of House Alarm.

To rectify point 2 you need to use whats known as Port Forwarding. In your router settings look for the Port Forwarding settings. Add a new rule to forward any traffic from port 80 (or whatever port you entered in the House Alarm Port field) to port 80 of the Internal IP address that was setup on your IP100/150. An IP150 may be listening on port 443 instead of 80 if SSL has been enabled on the IP150. If thats the case also make sure you enable SSL in House Alarm and that your Port Forwarding rule forwards all traffic from port 443 to the Internal IP address that was setup on your IP150.

If you only need access to your alarm from your home Wifi or if your IP100/IP150 is not on a home network that has internet access then enter the Internal IP into the Address field of House Alarm.

If you have no computer networking experience this may all seem a little overwhelming. Its really a straightforward setup for anyone with a little networking knowledge so in list someone if needed. Its important to remember this only needs to be setup once. Using a DDNS service with Port Forwarding on your router is a really reliable method to connect to your alarm system using House Alarm from anywhere.

IP Password

The password of the IP Module.


The pin number that you use on your alarm keypad.

Http Port

This is the port House Alarm uses to connect to your system. House Alarm uses the same port used by a web browser (Http). Leave blank to use the default Http port 80 or enter your own Http port number.


Secure Socket Layer (SSL) should only be enabled if you're using a Paradox™ IP150 and SSL is enabled on the unit. SSL is not enabled by default on the IP150.

Be secure. Use the Passcode Lock.

Using the built in Passcode Lock feature of House Alarm is recommended if you don't already have a Screen Lock on your device. This prevents someone from using House Alarm without your permission. If you're already using a Screen Lock or use a Touch ID device, you can leave it off for faster access.

My zone or partition information has changed.

If at any stage changes are made to your alarm system, such as adding a partition or changing partition/zone names, simply go to the Edit Alarm System screen and touch Save. This will cause House Alarm to update with the latest changes on your alarm system.

How does One Touch Arming work?

House Alarm has a unique feature called One Touch Arming that allows arming mode changes without having to keep the app open. The moment you have opened House Alarm and the connection sequence has started, you can touch the arming mode required. The button you have selected starts to flash, indicating the mode to change to. You can now safely press your iPhone/iPad Home button and continue to use your device as usual. House Alarm will notify you when the arming mode has changed successfully, or if an error occurred.

How do Notifications work?

House Alarm supports native iOS Push Notifications. Enabling Notifications replaces the email function. You will no longer receive email messages to any addresses you may have added to your Paradox system. However, Push Notifications offer a number of benefits over email:

  1. A loud, distinct notification tone.
  2. Touching a notification automatically opens House Alarm.
  3. Choose the types of notifications you want to receive from within House Alarm.
  4. Fast, reliable notifications that are configurable via the iOS notification system.

Up to 16 iOS devices installed with House Alarm can be setup to receive Push Notifications from a single alarm system. Enabling Push Notifications is an option for each alarm system you add. You can enable or disable Push Notifications for an existing alarm system by editing and adjusting the Notifications Enabled toggle switch.

Can I setup family and friends to receive notifications from my alarm system without giving them access to my alarm system?

Yes. Install House Alarm on there device(s) and setup a connection to your alarm system as usual. Enable notifications and choose the notification types you want them to receive. Save the changes and then delete your alarm system by swiping on the entry and touching "Delete". They will continue to receive notifications from your alarm system.

I am still receiving notifications from an alarm system after its been deleted.

You need to turn notifications off for the alarm system you no longer want to receive notifications for before deleting the alarm system. If you have already deleted the alarm system, add it again and turn notifications off and save. Now delete the alarm system again.

Is my Alarm System information private?

We do not store any of your Alarm System information outside of your device. Additionally, your Pin and IP Module password are stored encrypted in the iOS Keychain directly on your device.
