I installed it for parking at the gate, the hol router is in the first but not in a good spot, it caught the signal but sometimes it would freeze during streaming, okay, this was solved with an internal extender. I was torn between this one and the Vstarcam C16S, which has better features listed, but I preferred this one because of its reputation and after-service. So, the positives are good resolution, automatic day-night switching, small size, alarm mode. I inserted a 64GB Samsung U3 card and it supports it normally. It has a very good mobile application and there is a program for PC on the geyer website that supports Windows 7 and 10, I tried it on both and it records on the computer. On the negatives, I would have liked a wider angle and you should know that it does not support two-way communication, that is done by the indoor camera of this specific company. Also, it does not support channel 13, so for those who have changed the channel on the router, imagine it completely freezing on this frequency. It supports an Ethernet port, which always gives better results. Anyway, I recommend it for purchase, I hope I helped.
PS: After a month of use, it has not disconnected from the memory card, it has written 50GB out of the 64GB, everything is fine!
