Lerway 4.3"Audio Video Security CCTV Camera Tester 12V Output RJ45 Cable Test Monitor

I've had this tester for a few months now and I now believe I am qualified to pass judgment. First off I'm selling this thing! It works well, the battery life is awesome and the picture quality it good too. However the deal breaker is that this doesn't support cameras that exceed 500TVL. Most cameras now a days are 600, 700, 1000, 1200TVL and this tester will tell u No Signal for all of them.So for 480TVL or less cameras, this is a wonderful tester.

excelent toolsexcellent basic tool and this easy to use but testing works and is what I was looking for cameras and check data points

Very nice unit. Recharging takes some time but otherwise a great unit for setting up and focusing cameras.

I just received my cctv tester today. Size and ability is perfect for anyone in the cctv industry and the light was a perfect add on.

the screen lit it diaby then no one really brightened more than disappointment should change
