This alarm system embodies modern industrial design in a user-friendly, wire-free home security package. This alarm system is GSM-based (requires a SIM card) and suitable for any DIY home improvement project, ensuring you and your family have that extra peace of mind without monthly monitoring fees. The App is totally free. Once paired to your control panel, you can easily manage and interact with the entire system – such as arm, disarm, set exit/entry delays, add/remove/rename accessories, play user-definable onsite recordings and engage in two-way audio – directly on your smartphone anywhere, anytime. What this alarm system can do for your home or small shop/SOHO: l You can add up to 50 wireless sensors and accessories based on your needs. Those sensors and accessories allow for intrusion, flood, smoke and gas detection. l You can set exit and entry delays as you wish, so you and your family can go out and come back home at your own pace, without having to fumble around in your pocket for your mobile phone or remote control, to arm or disarm your alarm system. l Pre-set routines can be entered so that your alarm system will automatically guard your small shop or welcome you home right on the dot. Specific delays for specific zones are also possible. l Siren duration and volume can be adjusted per your need, with the maximum volume at 90 decibels. l Multiple users and smartphones can be enabled to control and interact with one single alarm system once paired. You can take turns watching over your property and loved ones back home.
