Very good camera with SIM card, does not have WiFi... It has excellent image quality. The person recognition does not work very well, it recognizes animals as humans.

After 1 month of use, I have to say that it is very good.
During setup, I encountered an issue with the data card because I did not use the one included in the package, but a Vodafone data sim card that has a pin which needs to be deactivated by inserting the card into another device.
You also need to enter the APN settings provided by Vodafone.
I inserted the Vodafone card without doing these steps and it didn't work, even when I did them later.
That's when I realized that they have very good support (not here, but in England) because the computer that responded to my email provided solutions and I deleted the camera from the application and reinstalled it, which made it work.
If you insert their own card, it works immediately, but with a payment package.
I have connected it to the solar panel (extra 60 euros) for autonomy, but the location where I have it doesn't have good sunlight.
I have to lift it up so that it never needs charging.
With one charge without the panel, I estimate 3-4 weeks of operation in normal mode, not power saving.
There is no issue with colors and clarity.
However, there is an issue with activation, which can only be done up to a maximum of 6-7 meters.
Nevertheless, notifications come literally in a second.
The application and installation are very simple.
Access from multiple devices and easy settings.
It also has GPS in case of theft.
I consider it a decent 4G camera for 215 euros.
Ideal for a vacation home or property where there is no Wi-Fi and electricity (as long as the panel doesn't have obstacles and trees in front of it and can see the sun).

Like all Eufy cameras, this one also does what it promises, except for the battery. While WiFi cameras provide the autonomy stated, this one barely lasts two months if it doesn't have a good signal.
