BT Home Hub DNS Issues with cctv system

[mikecctv]

Hi Everyone,
I have a CCTV security System connected to  bt home hub (white w/phone) ,I have set up a dns address
@ dyndns.com,the problem is the dynamic address is not being updated on router so i cant log in to view
cctv,the pc is off most of the time,but apparently this router has an in built updater,does this need to be activated/enabled??
any help would be appreciated...I have set up port forwarding etc. and i have accessed when originally set up( before ip address changed!!)

mikecctv, 

yes you will need to enable dynamic DNS on the hub. Go to Advanced, then click Continue to advanced:. On the extended menu at the left under configuration click Dynamic DNS at the bottom and you'll be able to enter your DynDns details in there.

Can you please advise how to configure dynamic DNS on homehub 3.

Your assistance would be much appreciated.
