PEGATISAN 5 inch 4K IP and 8MP AHD CVI TVI SDI CVBS 6-in-1 CCTV Tester with VGA and DHMI Input POE Output

I was really surprised with how much functionality this thing has.... you can power devices, record audio input, trace cables, test cable speed, etc. Other devices that do this are typically thousands of dollars.The only real issue I've had with it, is that the cable tracer wouldn't work once until I restarted the tablet. Other than that it's just a bit slow to boot and open apps but definitely not unbearably slow. I would definitely recommend downloading an .apk for a trusted app store since it doesn't come with Google Play. Then you can add other apps.I REALLY wish it had a USB port so you could plug in other devices.
