Functional Interpretation ◆ Out of home deployment Host enters alert state when user is out of home, and when detectors are triggered, host will alarm at once. ◆ At-home deployment Host reacts only to the entrance/exit or peripheral detectors when the user is at home. ◆ Dismissing Host suspends the ongoing alarm, and after dismissing the defense, the host will not alarm when the ordinary defense zone is triggered (except for emergency warning). ◆ Time delay for deployment 4 After host deployment, the time delay is established to prevent false alarms caused by users leaving the site and passing through the armed area. ◆ Time delay for alarm The host will not alarm instantly after the user comes back and passes through the arming area to trigger the detector, which provides some time for the user to withdraw the defense of host, and the host will only alarm when the time is overdue and cannot be withdrawn. ◆ Alarm Once the host produces an alarm task, the site gives an audible and visual alarm, sending an SMS alarm to the preset cell phone, dialing the preset user phone and pushing the alarm content to the cell phone APP. Host Networking Application Download ◆ Smartphone with Android System: Download "Doodle Smart" from the Applications. ◆ Smartphone with IOS System: Download "Doodle Smart" from the AppStore. Running applications 1. Running "Doodle Smart" from your smartphone. 5 2. Registration and login (You can login with WeChat). Hosted Distribution Network Entering "8*" command on the keyboard, the "WIFI icon" of the host will flash speedily and the host will enter the EZ networking state. Once the network is successfully connected, the host's "WIFI icon" is constantly illuminated. In EZ distribution network state, enter the "9*" command on the keyboard again. The "WIFI icon" of the host flashes slowly, and the host enters the state of API network allocation. After successful networking, the host's "WiFi icon" is always on. The host is connected to the mobile APP through WiFi Two methods are available to bind the alarm to the APP, one is the intelligent WIFI mode, the other is the AP mode. 1、intelligent WIFI mode (open cell phone Bluetooth can automatically identify the device networking) Method of W100 series intelligent WIFI mode networking：After you login to the main interface, click on " + " in the upper right corner to "Add Device".
