Review on Wsdcam 7 Inch IPS Touch Screen IP Camera Tester Security CCTV Tester Monitor with SDI/TVI/AHD/CVI/POE/WIFI/4K H.265/1080p HDMI in&Out/RJ45-TDR/Firmware Update - Upgraded Model 9800ADHS-Plus for Enhanced Performance by Gene Evans

Product update - 2017-06-06 Received good service from WSDCAM customer service, JACK Tech Support, they helped me a lot with returning and changing devices to a new one, today I am working with a new device, which didn't cause any problems, I used the IPC 9800ADHS tester with CVI, CBVS, AHD and it worked great. I haven't used the POE functions yet, but I hope there are no problems. It's worth noting that the company was very good at customer service and helped with any doubts or problems, but although the support team informed me that they would cover the shipping costs for their part or that they would ship right back to me, it never was the ability to cover the cost of shipping the defective product from Panama to the product receiving warehouses and tubes for shipment. Hello, on April 14th I bought from Amazon WSDCAM IPC-9800ADHS plus, the product I received on April 20th and yesterday I opened the package and the product was reloaded and I have it today, on April 26, uploaded. I used the product at the same time as another one, the screen went dark but I can't see anything, restart the IPC9800 but still nothing, remove the battery and wait 30 seconds and reinsert it and nothing happened, now i decided to use 1 hdmi cable to see if there is anything on the screen and the picture can be displayed. The problem is that I can't see anything on the screen of the same device. I need to find out what happened to it. I can't use the buttons on the side of the device, the last thing I used before was to view the camera via RTSP via VLC, otherwise I didn't see anything," I wrote to the technical support center (tech- support @wsdcam.com) to solve this problem with your WSDCAM IPC9800ADHS device"
