Fortigate unable to view cctv in local network

[kaizhi_1023]

Hi, I wanted to ask is there any configuration to setup for internal network and ports for accessing the cctv?
Because I can view the cctv outside the local network (using mobile data or network outside the office) but I cannot view the cctv when im in the office using local network. Below is the VIPs I created, is there any other configurations need to be made?

Are your CCTV devices on a separate VLAN? You should be able to https directly to the IP of the CCTV (Camera). Do you have an NVR?

[kaizhi_1023]

No, they are in the same vlan. Only one. I can go to https directly, but the footage unable to see it, same as when I check in my phone. 
Yes, I do have a NVR. Hikvision

What message do you get when you goto it via https? Does anything load or do you get "This site cant be reached"

[kaizhi_1023]

No, I can go to the control panel inside, but I just cannot see the cctv footage. It is working on the phone when connecting to mobile data. Below is the server that I use to login

I think you have a plugin problem. I've had this in the past. You can either find a plugin for the browser you are using or download a tool like iVMS-4200 (Windows/macOS) which does not use the browser and try that.

But when the user view the footage on the phone, it cannot view. The settings is correct. Im not sure is it the previous setting for Fortigate is running pppoe, but now has changed to DHCP. Is there any routing need to be made? 

[kaizhi_1023]

Is there any routing to be made if access to xxx.fortiddns.com? Because the CCTV is using xxx.fortiddns.com, when for local pc to view has no issue, I have confirmed it, but only when internal accessing fortiddns.com has this issue. Can you advice for this? Thanks
