execrable April 1

This product is really bad. The manual does not match the device! The presence detection system does not operate above 15 cm. The A button does not work and apparently have to send commands from the remote control, so the automatic startup of the camera does not work (not possible to install this camera for 8 to 10 h00). 2 or 3 files, there is a file that is completely unreadable (with Chinese characters in the background and a wallpaper with I do not know what!). I tried several times to make it work and it does not work!
It was an important purchase for professional use and ask repayment of this product which is totally unnecessary. Also when we see the presentation of the product ... it's outrageous!
