Can't enter IPcam via browser or iVMS

Hello all.

I just got a camera from my previous job. It's an old DS-2CD2532F-IS model.
I wish I would use it like a peephole, but faced with some problems.

I can't enter it.
- I used several browsers,
- tried to add :80 after IP address,
- changed IP address from SADP
- tried to update firmware via TFTP server according to instructions, « TFTP server[192.0.0.128] initialized» but updating process doesn't start.
SADP and iVMS found it, but in iVMS my camera is shown as "Offline'

IR...
