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 Chris Morgan

I love my tester. Realizing this, I ordered another one and it was delivered to the place. That's how much I rely on this tool. Now I have two. I use it primarily for placing camera text, zoom and focus, but also rely on other functions like testing TV signals and cables. I give this product 5 stars, customer service is great too. There was a problem with the battery life. I contacted customer service via email and Jack immediately sent it to my office. Very happy with purchase and functionality.
