OdiySurveil(TM) 8 Channel RJ45 BNC Passive UTP Video Balun Transmit Transceiver for CCTV Camera DVR

Will it work for 5 mp hd tvi ?

Can it transmit my modern camera with 1080 60p ntsc or 1080 60i?

where is it made?

I am using induvial baluns on cat 6 cable at the cameras and at the dvr connection to clean up the wiring would this take the place of the dvr bulans
