I bought it through skroutz.
It's amazing. Cheap and user-friendly. I bought 4 cameras and also bought their memory cards. I installed them all by myself easily in the apartment of a person with dementia, one in each room. I placed them in certain spots, didn't screw them into the wall. The only thing needed is an application, which I downloaded on my phone, and I can simultaneously see all 4 rooms on my phone. It requires an extra adapter to connect each camera to the power, but luckily they have a long cable (comes with the camera) that reaches the outlet, so it's not like mobile phones that have a small cable.
It has clear night vision, and you can hear what's happening in the apartment, like if the person is talking to themselves or if the TV is on, you can hear it clearly from a distance on your phone. But it also has the ability to see what happened in the past from the memory card. It zooms in, goes right, left, up, down, and it's clear. And this way I can see if the person with dementia forgot to close their eye in the kitchen, because I zoom in there, or if the front door is left open, I can see it zoomed in from my own house. But the apartment where it will be installed needs to have wifi, and at the same time, you need to have wifi or data on your phone. So, I had to put a program on my mobile phone that automatically charges me 15 euros for 2.5GB and unlimited calls, just so I have data at any time. And I can say that the 2.5GB is more than enough for the month because I use it wisely. It just requires some initial setup, meaning all the work is done when you download the application and create an account, but it's easy stuff. The program I downloaded is called Mi Home. I don't know if it works with other programs.
If I can say that there is something a bit disappointing, it's that I can't view the cameras from my laptop. Meaning, I can't see them on the computer, only on my phone. My acquaintances told me that in order to be able to see the rooms on the laptop, it's a complicated process, and I don't know much about computers. It would be easier if I could constantly view the rooms from the computer. While on the phone, I can't have them on the screen all the time because my phone overheats, and after a while (when I watch the rooms for a long time), it shuts down due to the heat that developed. Of course, my phone is 5 years old, and I don't know if it would have a different behavior if it was a newer one.
