This camera is really garbage. If it says it can't be used, then it can't be used. Last night while I was eating, my phone suddenly popped up a notification saying the camera was offline. Today I hurried to take the bus back to see what's going on. I just unplugged and plugged the power cord again, but nothing changed. I pressed the factory reset button on the camera itself, but it didn't respond. I followed the tutorial and searched on the same Wi-Fi, but I couldn't find the camera at all. I pressed the reset button again, but still no luck. It seems this camera is already broken and has reached the end of its lifespan. This camera is from Lechange. I bought it two years ago on Pinduoduo for 284 yuan, thinking that a more expensive one would last longer, but it broke down within two years. How much should I spend next time to buy a new one? Do you guys know which brand of camera is good? Brothers, please recommend some. I don't want to get fooled again.
