Model: DS-7608N-E2/8P
Mother board#: DS-8516 REV1 JP3
Original firmware: V3.4.2 Build 160226 (Hacked to EN)
Updated to: V3.4.6 BUILD 160405

The above information is for my current Hikvision NVR.
Since I have updated the firmware from v3.4.2 to v3.4.6, one of existing camera(Hikvision DS-2CD2512F-I) is not working at all. Simply the NVR could not recognize it.
It was working well with the firmware v3.4.2.
And one of my existing cameras (Hikvision DS-2CD2135F-IS) failed which appears to be out of order, so I purchased a new camera, Hikvision DS-2CD2143G2-I. the NVR could not recognize the new one either.
All the other cameras (Hikvision DS-2CD2135F-IS) are working well without any hasssle.
Could you please shed some light on this.
 
To recognize the new camera.

Downlaod newest Batch COnfiguration Tools
Add camera to it
Press System config dropdown
Password Protect -> Set to close (This is drop down camera security in order so old NVR can authenticate on it.)
