Very bad, always said that it is our own problem, we will not use it. The system update did not say that the maintenance staff did not finish updating the system, and the system could not enter. Why not tell me first? ? ! ! I feel very unhappy

720p advertises HD picture quality, but the result is only HD picture quality when you watch it in time. The recorded picture is played, but only the more blurred SD picture quality (it feels like being cheated by their ad text). The response has been for a long time, the APP never It is a problem of poor SD picture quality when modified the recorded playback.

Because of some problems, I personally went to exchange goods. In addition to unconditional exchanges, the service was very enthusiastic and very cordial. The service staff even took me to the car, which made me feel flattered and delighted, so I gave five stars a good review.

I bought an Internet video camera from online shopping IF-008B breaks after using it a few times and it's not durable

They use the latest H.265 (MP4) format. The advantage is that the file size and code stream are reduced by more than half, so the transmission of images and sound is smoother, and the storage time of recording and recording can be more than doubled. There are many free players on the Internet such as PotPlayer, VLC media player... etc. As for transcoding, I personally use PowerDirect to edit and transcode. The commonly used Line, Yutube and FaceBook on the market all support H.265. (MP4) This format, I suggest you go online and google it.

I bought a 16-channel NVR and felt that the manual was printed with inkjet printing. The diagrams were shrunk and squeezed together, and the words were very unclear. I don't know why the company wants to save that money. There is no hard disk installation and external wiring instructions, so call to ask. After the installation, connect the screen and power, and a message that needs to be formatted appears, and then you need to enter the password. The default user name is "admin", but there is no default password in the manual, only the page where you need to set the password first. In other words, Mingshu is seriously out of touch with the actual screen. This should be a small company that is poorly managed. I will give a star first. If tomorrow and the day after tomorrow, I will ask the customer service to solve the problem of password and hard drive formatting, and then the camera is installed successfully and the hardware is really easy to use. I will raise the rating. I forgot to say that the NVR host is very hot, and the heat dissipation is not good. There is a small motherboard and hard disk in the box (not formatted and Running), don't know where the heat comes from.

The monitor was repaired quickly and returned very quickly, it only took three days before and after, great
