Question: how do you connect the three monitor to gather how dose it work ? and what kind of cable do i need because  i need about 50 ft
Document: The product appears to be seconds that were damaged. The screens on all three monitors are scratched and one is warped. The volume at max requires you to speak loudly and close to the mic to be heard. The buttons don't always do what they are supposed to do. Sometimes they work and sometimes they don't. Overall quality is poor. Be careful not to bend connections when installing. The intercom function does not work. The operation manual is poorly written and difficult to understand. It does not explain operations well. The camera needs a wider angle lens.
The 7 Inch LCD Color Video Door Phone Doorbell Intercom Kit 1-camera 3-monitor Night Vision, is ok. The product working properly and the service was excellent.
It's easy for the caller to not be seen if they move slightly. The picture is good day or night. The doorbell has plenty of volume. Installation is simple and more parts than you need are included. If you want a doorbell that costs less than the big box stores, always rings and shows a video, but not always the person ringing, this works. If you want to talk to the caller, sometimes it takes some button pushing to get the video and audio back up. Don't buy it for the intercom.
This is a good product, it works as described, but cables are too short, and nobody knows where to find longer cables or replacements. The seller contacted the manufacturer and was told that there are no longer cables for this product.
The transaction was done on time, there was nothing new. The equipment is working properly, the video is of high quality and sharpness, the only downside is that one of the adapters I burn, maybe I can tell where I can get.
Answer: no
