Installation is very difficult to the point of being tragic, and the sound of the monitored area's speech cannot be heard unless someone shouts loudly or gets very close to the camera!

The connection is lost every now and then!! The connection does not easily recover!! Out of the 10 cameras I have, it is the worst!!

I was expecting something worse, good picture, the sound is not clear but for the money it's good, worth it, now time will tell

Average quality of construction and durability over time. Over time, all the LEDs of the night vision in one camera burned out, eight burned out in the second, and four burned out in the third. Additionally, a downside is that after a few minutes of monitoring, the image freezes and you have to refresh it, as well as the fact that almost every day you have to adjust the time and date because it becomes unsynchronized

Do not buy it if you have a 50-line!
The product supports up to 24-line Wifi.
I just received it and I'm going to the store to exchange it.

Everything is fine except for the following.
1. When the sound is activated, it makes a lot of noise, resulting in you having to turn it off yourself after a while due to the headache.
2. Approximately every 30 minutes, it loses connection, so the image you see "freezes". It can be solved with a simple refresh, but there is a chance of getting confused, thinking that you are seeing a live image.

Very good with excellent resolution and perfect image even at night. The only negative is the small power cable, as it needs to be constantly plugged into the socket. I hope it will last for a long time.
