"Camera" does not meet the declared parameters:
1. regardless of the settings, removes only with a resolution of 640x480 (vga) (declared max 1920x1080)
2. viewing angle ~ 40 ° (in the description on aliexpress declared 170 °, on the package 140 °)
3. the sensitivity of the matrix is below any criticism
4. recording time on fully charged battery ~ 40 minutes (declared 90 min)
5. open the battery cover, without its damage, it seems impossible, so did not do it, so as not to damage the appearance.
Of all the above i conclude: to use the product for its intended purpose-it is impossible
In addition, i think that the description of the camera, contains an attempt to mislead: when choosing the color, the models of the cameras of another manufacturer "black sj4000", "black sj9000"
