With the Eminent EM8610 wireless alarm system, securing your home or office is made easy. The system works with a SIM card that you slot into the control panel. Thanks to the SIM card, you won't need a network connection or landline. You can configure the system and control it remotely with an app for your smartphone/tablet. When the alarm goes off, you'll receive an SMS message or phone call from the SIM card in the control panel, after which you can switch off the integrated siren (in the main panel) by sending an SMS message or making a phone call. The control panel features backup batteries, so the system will continue to work in case of a power failure. The motion detector, the window/door contact, and the control panel are battery powered and can be positioned wherever you want. You can easily expand the set to include up to 50 wireless sensors.
