Chuango profile: Chuango Security Technology Corporation is an innovative manufacturer of electronic security products. Adhering to the brand promise of "Sincerity and Innovation" and associating with our deep comprehension of users' demands, we integrate the technology and design into people-oriented products to provide "easy-to-use" security products and solutions for global families and commercial clients. Another signature system design from award-winning Chuango Security Technology Corporation, the O3 comes with world-class aesthetics and German-style precision craftsmanship. Chuango O3 is your 21st century security guard in disguise, made for wireless DIY comfort and convenience, and is particularly suitable for residential and small commercial applications. All you need is a Chuango O3 set and a regular SIM card. What your wire-free Chuango O3 can do for your home or small shop/SOHO:  [360° Protection] Ideal for DIY home/shop improvement projects, the O3 can accommodate up to 50 wireless sensors and accessories, which can be easily “mounted” on walls or door/window frames with double-sided stickers. You will be the first to know – via this App – upon detection of intrusion, flood, smoke or gas.  [360° Convenience] 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 Chuango O3. Pre-set routines can be entered so that your O3 will automatically guard your small shop or welcome you home right on the dot. Specific delays for specific zones are also possible.  [360° Deterrence] Siren duration and volume can be adjusted per your need, with the maximum volume at 95 decibels.  [360° Interaction] You can manage and interact with your O3 on your smartphone App, via your remote control, or directly on the panel. It can also double as a house phone to make or receive calls.  [360° Sweet Home] The RFID tags can be renamed at will, and when used to disarm your O3 system, you immediately get an SMS text notification of who just came home. Multiple users and smartphones can be enabled to control and interact with one single O3 system once paired. You can take turns watching over your property and loved ones back home.
