Productbeschrijving
Het grootste voordeel van deze camera is de lens met 45 x optische zoom. Deze lens, gecombineerd met een krachtige illuminator, maakt 24/7 bewaking mogelijk zonder extra verlichting, zelfs over een gebied van enkele honderden meters. Dit maakt de camera ideaal voor bewakingssystemen waarbij identificatie van personen of voertuigen vereist is.
Dankzij de "Starlight"-technologie is de camera zelfs bij zeer weinig licht voldoende voor een helder kleurenbeeld. Het door de fabrikant opgegeven bereik van de illuminator is afhankelijk van de omgevingsomstandigheden (luchttransparantie, omgeving, muurkleur, zogenaamde "scènereflectie". Reflectie van de scène).

Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

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.
