MobiBell is a smart bell, perfect for those who want to keep their home safe without worrying. It has a PIR mobile sensor that detects people and automatically triggers a camera to record people at your doorstep by sending a push notification to your smartphone, so you can track everything in real time. You can also interact with them because the ringtones have two-way audio and crystal voice, making communication with visitors easy. There is no need to pay for cloud storage because it has an entrance to an SD card up to 32GB. With excellent night vision images, you can still rely on 720 pixel resolution and protection against dust and light water sprays.
