4K 12MP IP Camera Tester, WANLUTECH IPC Tester 90W PoE Power Output 8'' Touchscreen CCTV Test SFP Optical Fiber Module Port RJ45 Cable TDR Test WiFi Network Tools (E88)

If you do security cameras - BUY THIS! Well worth the money and works well. Only thing to really ask them to improve is that its a pain to try and get screenshots off of the device to send to a customer. (I use this tablet often to test out camera locations and viewpoints before mounting and wiring cameras).

Needed an ethernet line tester to test opens on cable, fantastic !! Does an OTDR test on each individual conductor.

Excellent for installers, make testing and installations more easier. Have lot of features

UPDATE: AFTER USING 2-3 TIMES ITS NOT HOLDING THE CHARGE ANYMORE I wanna thank the company to my life easier , i have 8 cameras new construction , all sprayed foam , plumber guys cut 2 wires by mistake ,i tried Klein pro and pro3 didn't do anything , i saw this item on amazon i sad let me give at try , this thing is life saver , found the exact length of the wire , shows wiring diagram unbelievable the best , its like small iPad , you just have to play around with it before you start using it , if they had 10 star i would give 10 star easy AGAIN THANK YOU SO MUCH

Nice device with many functionality
