Better Security

    Much More Than An Alarm. DDA Systems offers wireless home or business security systems that let you arm or disarm your system remotely from a computer or smartphone, watch live video from multiple security cameras and access a complete, searchable event history, giving you peace of mind that everything is okay when you're not there.


    Mobile Apps

    Security you can take with you. Log onto DDA Systems through your BlackBerry, iPhone, Android or other mobile device to check current system status, monitor your property and send commands to your security system. You can also sign up for real-time text and email alerts to find out about any type of system activity that matters to you.


    Video Monitoring

    Reality TV that's worth watching. Using multiple security cameras with DDA Systems' advanced Video monitoring technology, integrated with your security system, will truly change the way you see your home or business. DDA Systems cameras can wirelessly stream live video, sense movement, save recorded clips, and trigger email and text message notifications.


    Interactive Services

    Stay Secure. Stay Connected. We use the Internet to make our lives easier and to interact with what's important to us. DDA Systems brings that same convenience, flexibility and control to security systems using wireless web and mobile technology you're already familiar with,  enabling you to monitor your home or business when on the go.
