4K 12MP IP Camera Tester 90W PoE Power Output 8'' Touchscreen CCTV Tester 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).

Works great battery actually lasts a long time

La mejor herramienta que he podido alcanzar. En verdad se pasaron con la calidad, su funcionamiento y el precio.

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

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
