Presently I have a wireless CCTV DVR connected to my TP Link 4-port router modem with Lan internet cable running on streamyx 8mbps. It works well - I am able to use my computer and view the security video on my phone remotely.

Lately I bought a Tenda 4G680 sim card modem router and purchase Maxis 6G8 Hotlink Red sim card to try out the CCTV connection. I connect the Tenda modem to my computer and wireless CCTV DVR with Lan cables from the Lan ports like in my previous set up. It works well with my computer but not on the CCTV.

Can anyone point to me:

1. Why the CCTV is able to work on my TP Link modem running on streamyx but not on my Tenda modem running on Maxis Sim Card?

2. The steps need to connect the Wireless CCTV DVR to my Tenda Modem running on Maxis hotlink red sim card?

Thanks

Thank you very much KKTECHHUB.

I am not IT savvy in all these jargon like P2P, upnp, private and public IPs.

Can you tell me how to set up my cctv for both private or public IPs?

Some people say to use VPNs. Is this an easier solution?

Thank you once again.

Thanks again, KKTECHHUB.

I am not very well verse in setting up p2p for my CCTV but I'll read and research more on this.
