The delivery was very fast, just less than 2 weeks. However the items shipped have some issues:
1. The items delivered differed from the one displayed: note that there are 2 push buttons on my board versus one on the images shown on the website. The setup of the board is done with combination of those two buttons and the potentiometers This is not the same as the advertised board. It seems that the basic functions is the same as the advertised board though.
2. It seems that the default output voltage is set to 20V. This means that when testing the board below 20V the output varies with the input. But this can be adjusted as required.
3. One surface mount component on one board has come loose, possibly with shipping as the the items where not securely packaged but arrived in plastic pouches with no protection.

Q: Does this doorbell come out to unlock the electric door?
尋ねた brunobartos に 2019-09-04 02:35:37
imtschmid The doorbell system cannot unlock a door but you can have a separate smart app on the phone or a manual button for unlocking.

imtschmid For micro SD check the slide cover at the top of the camera. It hides the USB and SD ports.

Q: est ce que je peux gérer 2 porte de garage? can i manage 2 garage doors?
尋ねた mike.cauchon に 2020-06-24 08:01:10
imtschmid It should be fine as long as your total current doesn't exceed 16A (4CH R3) or 40A (4CHProR3) and each garage door uses less than 10A. This is all described in the specification.
