GREENCYCLE KS-SF20R Motion Sensor Doorbell: 5 Modes Motion Sensor Alarm
🚨 5 Modes Motion Sensor Alarm - Think of this as your home's Swiss Army knife for security. It's got more tricks up its sleeve than just ringing when someone's at the door. Welcome guests, scare off intruders, light up your path, or set the mood with color—all from one sleek device. Ideal for keeping an eye (or ear) on those sneaky spots like driveways and porches.
🎵 36 Ringtones & 5 Welcomes Doorbell Rings Languages - Bored of the same old ding-dong? Spice it up with 36 different sounds or greet visitors in one of 5 languages. Plus, you can tweak the volume and brightness so it's just right—whether you're trying not to wake the baby or you just like things loud and clear.
📡 Sensitive & Wide Wireless Range - This little gadget's got reach. Up to 280 meters, to be exact. And with its infrared sensor, it'll catch movement from 2 to 8 meters away. So, yeah, it's pretty much got your back (and your front yard).
🏠Expandable Wireless Home Security - Want to turn your place into Fort Knox? Go ahead, add up to 32 motion sensors and 8 remotes. Just remember, it's not a fan of water—keep it dry.
🔧 Easy to Install & Use - No need to call in the pros. Pop in some batteries or plug it into a USB port, and you're good to go. Comes with mounting bases, and you can twist and turn the sensor and receiver to get the perfect angle. Easy peasy.
