creat a freedomain in DVR

I want a domain default in MyDvr

In many DVR I i know when i acess DDNS in the DVR have some type (CN99,No-IP,dyndns,quickddns

example :cctv.dyndns.org ) to add domain and now i want to have own domain example abc.global.tv

so what should i do ? should I buy own sever for mydomain ?

I hope somebody give me advice

You can do one of two things

either contact a local CCTV installer and ask for a host-name on their server or

open either Dyn dns account or No-IP account and create your own host-name.

You would still have to manage it if things go wrong but it's in your control

With both of these you will have to pay an annual fee but its still cheaper than paying for a static IP address
