Unfortunately, all the information regarding the camera resolution is incorrect.
Product image (top) → 2MP
Product description → 3MP
Product image (at the end of the sales page) → 1MP
The actual performance of the product is equivalent to 640×480 (VGA), with a pixel count of approximately 300,000 pixels (0.3MP).
※The settings provide three image quality options: SD, HD, and FHD, but all image qualities are equivalent to VGA.
※The file format of the video recorded on the Micro SD card is AVI. Even with VGA resolution, it takes only a few seconds to generate several MB of data, making continuous recording impractical. By the way, the specification is such that the file information is displayed incorrectly by default (this applies to Windows only, but there is a bug where the file recording time is not displayed correctly).
In addition, before the 300,000-pixel era, the performance of the processing circuit was low, and the image quality was very poor.
Would it be clear to write that the image quality is neither better nor worse than the low-quality videos circulating in the Heisei era?
Anyway, if you are considering making a purchase, please be careful.
That being said, it's impressive that at this price point, it can achieve features such as electric directional adjustment, direct communication with smartphones, Wi-Fi communication via a router, video recording and still image capture on a Micro SD card, and night vision photography.
If you use it in a pragmatic way, I think it will be very valuable.
The power supply is connected via USB Micro B. In Japan, it can be operated without any problems using a USB adapter from a standard household outlet, but it can also be powered by a mobile battery, so it can be used in environments without outlets for short periods of time. For your reference.
