Linkind Smart Home Security System Starter Kit, APP/Keypad Control Alarm System for Home Protection, 2.4GHz WiFi Only, 5 Pieces, with 110dB Siren Alarm, PIR Motion Sensor, Door/Window Sensor

Double Protection: Siren+ Alert Linkind Home Security System acts as a deterrent to stop a burglar from breaking into your house, while keeping you informed the status of all your sensors via the APP. No subscription service is needed. The alarm system still works even the network is down (but alert cannot be sent). DIY Installation It is a highly personalized system to set up and expand. It’s up to you to set the alarm volume, duration, devices to be included, how long the system will arm itself after you exit or enter your house etc. More accessories can be added to enlarge the detection range. Minimalist Design The minimalist design embraces simplicity. All parts of the security kit are downsizing to the minimum to save your space, but not compromising their performance. Ideal to integrate themselves into your house without being obtrusive. Anti-tamper Against Intentional Removal All sensors are equipped with a mount bracket, which is a tool for installation, but also a “lock” to switch on/off the anti-tamper button at the back of the device. The anti-tamper button is “off”, if push the bracket along the arrow mark to get it locked with the sensor. It is “on” and will trigger alarm and alert instantly if it is removed. Note: Remember to disarm the system before you disassemble the bracket and cover to replace the battery.
