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 Chuck Shapiro

month The tester definitely does a good job, too bad PoE no longer powers the camera which was the main reason I bought it. Without this feature for IP cameras, it's essentially a waste of money. I have contacted Revain but as the item was over a month old there was nothing they could do to direct me to the company that sold it to me. I was angry when I bought it. I contacted the company, they want me to send the device to China for repair. The device is basically good, but not very efficient in terms of construction, since the network connection is under the device and the tester is on the stairs on its stomach, which causes the connectors to bend (mains plug / mains plug, in the long run they will simply break. the battery lasts long. the touch screen is definitely handy the hdmi input has a 2 second delay and it is very frustrating when programming any device with the mouse. i will give this device 3 stars if only the subsidiary would handle the warranty direct from the usa If I could I would rate this as an extra star UPDATE: I have contacted Jack and he is really supportive of his product, he will send me a new unit for free Definitely 5 stars for the support.
