Hikvision ColorVu camera problem

[wesam_az 0]

hello 
I have DS-7216HUHI-F2/N Hikvision DVR , tried to add another surveillance camera which is (DS-2CE12HFT-F), it doesn't show any video.
Is DS-7216HUHI-F2/N DVR compatible with the camera mentioned above?

Notes:
I connected the camera with network cable via video BALUN . 
also tried to cover the camera lens but IR light didn't turn on

could you please help me out to solve this problem
any suggestion would be appreciated

Thanks in advance
