Convenient, discreet, and small size, it came with all the accessories, easy installation. The app from the Play Store is a disaster, terrible, completely unacceptable. I couldn't pair it, it asks for location permissions, a ton of them, it made me angry. It needs WiFi, it doesn't connect with mobile data, it doesn't have Bluetooth. After ten days of use, its charger, connected to the lighter, made a bang, exploded, and caught fire. I feel lucky it happened in front of me and I managed to prevent the worst. Pay a bit more and get something more worthwhile. Not even one star, wasted money

In my case, the package did not include a rearview camera (I don't mind because I wouldn't have installed it anyway). I have installed a 64GB card which is working fine so far. Its size is quite small (imagine about 2 matchboxes side by side). The battery that the camera has is only for safe shutdown at the moment you turn off the engine.

It has WI-FI.
I downloaded the camera's app from the Playstore and made the necessary settings I wanted.
It says it has 1080 HD resolution (it is not 1080 by any means, but at best 720p).
I have installed a 64GB card (actual 58GB).
I have set it to record 3-minute videos (which are AVI and have a size of 650 MB for the front camera and 430 MB for the cabin camera).

Be careful when receiving your orders, check the product codes. In my case, although I ordered the same DVR camera from the same store again but on a different day and they seemed identical, the camera I received had many differences in details (menu, WiFi, rearview camera, etc.)

I've had it for 5 months, I haven't had any issues, it records very well. The menu is a bit random but you don't need much. It records automatically and everything is visible. The only downside is that it restarts when the card is full and starts recording from the beginning. Just hope nothing happens at that moment

after using it for a month
it's not bad for its price, although i have to keep it away from the direct sunlight when parked to avoid it melting in this heat wave

The build quality seems a bit fake, time will tell if it lasts. It doesn't have a Greek menu. But even with English, you can set it up just fine, it's very simple. To use the memory card, you need to insert it into the camera and format it.

The most important thing is that it doesn't record if the car shuts off because it doesn't draw power and the battery runs out in the fourth recording! So if you want something for 24/7 you need a specific cable that connects to the fuses. Also, it doesn't include a micro SD card (necessary for the camera to record) and supports up to 32gb (few for a recorder!). Also, regarding the smart features (e.g., motion detection), the recording is only activated by the front camera!!! For example, if someone comes from behind and hits you, the camera won't notice...! The screen, combined with the very mediocre resolution, is almost useless; good luck distinguishing anything. The interior camera is something close to 240p if not lower! No, I do not recommend it; spend a little more to get something better and don't make the same mistake as I did. If I could, I would have returned it yesterday...

It has many similarities, I can't express an opinion about the others except for this specific choice. The image it has doesn't interest me, I didn't get it to look at it. It indeed has 3 cameras inside and puts in 32GB of memory and many options in the settings. When you turn off the switch, it shuts down and I think it's impossible for it not to hold with a battery. So you press the Power button after you've removed the car key and it works with the battery. I don't know how long, but for the five minutes I left it, the battery didn't go down. A great choice for its price.
