4 in 1 CCTV Camera Tester, JZTEK 5 inch LCD Screen Video Monitor for 1080P/3.0mp/4.0mp/5.0/8.0 Megapixel AHD/TVI/CVI/CVBS Analog Security Camera, PTZ/UTP Cable/Audio Tester w/2600mAh Battery, VGA&HDMI

Handy little tester if you do CCTV installation. It charges on micro USB has video in to make setting up a DVR easy using HDMI or vga. Will power your cameras and show the video to get them aligned without the help of another person. Body is quality made comes with carry strap and cables would recommend getting a VGA and HDMI cable to round out the kit. Over all really good tester for security camera techs doing install or service.

Just as advertised. The push button for the on/off switch is a poor design if you consider a technician with it in his tool bag, it is easy for it to be powered on and drain the battery down and it ends up being dead when you go to use it.

Works great except that I was unable to program tvi cameras.

Got three uses out of it. Treated it like a baby. Power light comes on now with no screen. DO NOT BUY.To the manufacturer, I would consider a replacement to test if this was just a lemon.

Liked that the device was able to pull up video streams. Uses 18650 batteries. Has video input for HDMI. Expensive and cannot replace UTC device to switch video format for camera without buttons. Just wished it did more for the price

I like the flexibility of having a mobile monitor to troubleshoot 📷 at work.

It worked extremely well I'm no real issues with it .

Very easy to operate, picture not as clear as expected. Neck strap very convenient. A little higher priced for the quality, but it does work
