Productbeschrijving
Wireless Dual-Tech Detector is een binnendetector die menselijke bewegingen detecteert. Met behulp van passieve IR en microwaredetectietechnologieën detecteert het apparaat de beweging van personen en detecteert wanneer ze het detectiegebied zijn binnengekomen. Door deze technologieën worden valse detecties veroorzaakt door thermische interferentie ook sterk verminderd. Het apparaat is eenvoudig te installeren en te gebruiken en kan direct op de app worden geconfigureerd.

Excellent buy
Color: pink
I ordered this case for my new IPad. This case is awesome! Not flimsy and bulky. I loved that it had a screen saver included in the case. It was easy to put on my IPad. Snapped together good. The price was excellent! The case keeps all dust off the screen. The screen is easy to clean. I highly recommend this case!

Great quality at a remarkable price
Color: Navy Blue
I got an iPad and was looking for a cover to protect it. I came across this case that has a Bluetooth keyboard. It seems to be working great. It was less than $30 and had 4.5 stars with over 4k reviews.
The keyboard is magnetic and detachable, so I’ve got lots of configuration options. The keyboard pairs easily and allows you to use the iPad like a laptop. The point of an iPad a lot in one shot is kind of the touchscreen, but when I’m typing a lot of text as once (like now), it’s really nice to have a physical keyboard and touchpad. The keys are comfortably spaced and I’m comfortable typing on it. There is no additional setup for the keyboard besides pairing it to the iPad. At that point, all the cursor and keyboard features are immediately available.
The case is well built and has nice features like a slot to hold a stylus and multiple grooves to set your viewing angle. It’s configured to be used in landscape mode, but if for some reason you wanted to use it in portrait mode, you can pop the keyboard off to lay it flat. Especially for the price, this is an exceptionally nice iPad cover.
