inadyn + ispconfig3 on fixed IP

Hi all,

was wondering the following.

I have a domain-name at an ISP which doesn't support dynamic IP's.
I have a couple of servers on fixed IP's ( not related to previously mentioned ISP ) running ISPconfig 3.

I have at home a couple of (IP) cameras with Zoneminder which I want to make available online using a subdomain of previously mentioned domain.

I added an A-record on my ISP's control panel that points to one of my servers (running ISPCONFIG) and was wondering if I then could use inadyn on my home server to do the IP updates on ISPCONFIG and do a kind of redirect to the dynamic IP ( the server running zoneminder ) associated with that subdomain

Any other ideas are welcome. I prefer not to use dyndns/freedns for this.

thanks in advance
Jan
