After 1.5 years, suddenly the switch of the board did not stay in the ON position. It took about 5-10 presses for it to work again.
I removed the board to replace the switch and discovered a capacitor with a loose terminal in the air (not soldered).
Also, the screws that held the power cable plug were decorative (loose bolts). And the quality of the plug was poor, with already cracked plastic and no support on the board, despite the presence of slots on the board.
The resettable fuses were soldered crookedly.
The quality of the transparent cover was also poor (it started cracking as soon as I tightened the screws).
I have used the same product in other installations without any major issues (only one had some lines on the cameras).
However, this particular one caused problems with the customer who trusted me to use reliable materials.
I heard phrases like "What did you put in? It broke so quickly. I had the old one for ten years and it was fine." And various other things
