Let it read out the standard alerts, or customize the message; it's up to you! - WHY PAY A MONTHLY FEE, when you can secure it for free?

Place a sensor on each exterior door and window to 'Protect Your Perimeter' Activate and control lighting.

Use our SpeakerHub, our audio hub, to play a tone or message, alerting you when a door is opened or left open too long. - NOT YOUR FATHER'S DOOR SENSOR! This is a sophisticated electronic device, utilizing the latest technology. 24/7 cloud server device supervision monitors your system for online presence, signal strength and battery level, to ensure it will work when you need it! (Hub required, for full functionality) - DEVICE-TO-DEVICE PAIRING: a unique feature, two or more devices can be paired together. Even if the internet is out and the power is down, they will carry out their paired actions. Pair your door sensors to a Siren Alarm, then turn it off when you want to "disarm" your system. Use a SirenFob or FlexFob to control your siren. Make your own custom security system! - DON'T TRY THIS WITH WiFi! LoRa is short for Long-Range. Boasting up to a quarter-mile open-air range, and operating at the 900 MHz band, YoLink devices can be placed where your WiFi probably can't go, such as in basements, separate buildings, even on RVs and boats stored on your property!

Or is it an alarm that people walking by outside can hear?** A: You can set it to text you or to have the hub alarm inside the house go off. My hub is in my 2nd floor bedroom and alarms on on my doors on 1st floor. So people opening the doors don't hear it I did that because I have an dementia patient at home and it notifies me if they try to leave house when I am sleeping but doesn't scare them **Q: Can app alert you every time do is opened?** A: Yes, you can set up notifications in the app **Q: I can not get the door sensors to bind . i have the app and hub successfully connected to wifi. door sensors blink one red light with button is pushed** A: Read the QR code on the sensor with your app first. **Q: Can the hub play a siren sound if the door opens or do you have to buy the seperate siren? I want to get a notice on my phone and an alarm sound.** A: The SpeakerHub can play a siren sound, but keep in mind it is not a loudspeaker (like our sirens are). The sound level is closer to an Echo Dot; it may not be heard throughout your home. But I have seen the SpeakerHub placeed in foyers and closer to the door locations, where it should be heard very well. This is also a good location, because you can have the SpeakerHub say "system armed" and "system disarmed" as you leave or arrive through that door. You should also take a look at our FlexFob and AlarmFob. https://www.amazon.com/dp/B0978V4WQC?ref=myi_title_dp&th=1 https://www.amazon.com/dp/B092M1QQ5M?ref=myi_title_dp&th=1 And here is our loudest siren: https://www.amazon.com/dp/B0BZHPQ1PK?ref=myi_title_dp&th=1 Enjoy!
