When purchasing this camera, I was attracted by the price and number of sales. Upon receipt I saw that one wire was not soldered. And the wires were not insulated from each other. I quickly fixed everything. Because I can work with my hands. Additionally, this camera uses AAA batteries. There is an error in the product description. The seller indicated AA. But overall, for the money everything is fine. I recommend.

Working fine. Note a difference between the versions equipped with a BELL key or with a # key:
1) the one with the BELL key accepts master code just typing in the code and that`s it. Very simple
2) the one with the hashmark # key needs master code followed by # key to proceed with opening.
Small difference, but the first version is more comfortable.
