Smart Door locks have a few advantages over traditional locks: You can control them remotely from your smartphone, issue temporary passes to friends, and see when—and who—uses your door. You can also connect them to other smart home devices, such as security cameras and video doorbells, so that you can unlock your door for a guest, even if you're not at home.
After reviewing numerous smart locks from several well-known brands, our top pick is the MANSVI Smart Lock Product, which was easy to install, has a number of optional accessories (such as a keypad and doorbell camera) and can be connected to a wide range of smart home systems, such as Google Home, and Nest. The Schlage Connect Touchscreen Deadbolt is a good option for those looking to save some money. However, it only works with Alexa, via the Samsung SmartThings or Wink hub.
MANSVI had made occupancy sensors for the use of home automation, commercial and industrial use in all the technologies which covers different detection range of area and with different mounting as per the need of the customer. Microwave sensors works on RF waves and it can sense small minor motions such as if someone crawls or walk inside the room irrespective of ambient room temperature.
