Working in a security system scenario
In some cases, the complex is purchased for this purpose. Indicators are the main element of visual notification. The first one is GSM. It flashes in case of successful registration on the network or in case of financial blocking (if the account has run out of funds). The second is SMS. It will flash when the user receives a message. Another indicator is PVR. It determines the status of the cameras. Lock LED:
- Not lit – no protection.
- Lit – security function is enabled.
- Blinking – the building perimeter protection function is enabled.
The Alarm LED turns on each time the sensors are triggered. The SD LED only lights up when a memory card is inserted into the slot. The stand-alone alarm unit supports 2 security modes. You can select the option “home” or “perimeter” using the radio remote control. Another option is control from a smartphone in the application (the mobile application does not allow you to change modes, only correct them). 
- Siren activation.
- Notification via SMS or MMS.
- Video / photo recording.
- Sending photos.
It must be taken into account that the siren will work constantly. It is turned off manually by pressing the “Reset” button on the case. In the case of perimeter protection – on a keychain. You can set up the remote access option in the mobile app. Download the smart home control application for Android via CADENA UMK-587 at http://www.cadena.pro/poleznoe_po.html
