I have a ZMODO ZP-IBI15-W.  I tried to telnet with putty and get connection reject also.  I tried port 23 and 8000.  Are there other port options I should try?  I want to try to use the camera without going through the zmodo cloud.

Hi Jeremy,  tried to telnet with Putty,  kicked me out.   But more important, I have the same model IBI15-W and after setup with Zink I cannot for the life of me find the port it is using so I am unable to connect to this camera with Zoneminder or anything except the stupid zmodo app.  Can you help me find the port that this camera uses and the correct path and protocol?  and btw not that I ever will - but how do you get a serial line to this camera?  please email me if you can  KenSilverman  over at rcn
