Preview BCS IP Camera Monitoring via VPN using Huawei B315s Router, PC-NVR, Smart PSS & OpenVPN

Hello everyone,
at the beginning I wanted to warn that I am a total layman in this matter, so please be forgiving

The case is as follows: I have a simple monitoring at work - a BCS ip camera connected to the Huawei B315s router (internet in PLAY network unfortunately), saving on a computer using the PC-NVR program, previewing the image using the smart PSS program. I would like to configure it in such a way that it would be possible to view the image from the camera from the outside. I know that there is no such option in the Play network, so I purchased a VPN for this purpose at vpnonline.pl. Because the wonderful Huaweii router that I have is not able to configure a VPN, I need to use a computer for this - it is not a problem either, I downloaded the OpenVPN program for this and here we come to the end. Unfortunately, I still can't manage to configure it. I would be very grateful for the "rough" instruction, what to enter where, as I wrote at the beginning - I am green in these matters.

Thank you in advance to everyone for your help

I suggest reading this information:
1. VPN connection configuration instructions https://www.vpnonline.pl/konfiguracja
2. Own private network http://www.komputerswiat.pl/poradniki/sprzet/siec-domowa/2015/07/wlasna-siec-prywatna.aspx

Thank you very much for the answer, but unfortunately these guides do not answer my question. I've seen it before, it just says how to create a connection, and I've already done it and it works. It's about how to get to the camera image from outside?
Probably somewhere I have to enter the IP address of the camera along with the port and somehow redirect it - but how?

For example - in the gdmss lite mobile application I enter the IP address of the camera and the image is displayed to me, provided that I am within the wifi network, if I disconnect from the network, the image will no longer be available. I would like to get the image by entering the ip address assigned by the vpn network being outside the wi fi network

BCS ip camera

Camera model? There is no case of cloud support (p2p)?

IP66 bcs-tip1130ir

P2p is nowhere in the settings

Do you have external access to your VPN account? Remember that the operator blocks ports and such a "prosthesis" may simply not work.

I can't check that, unfortunately

The matter clarified - after configuring the OpenVPN program, just connect to it, then in the smartphone preview program change the IP address from the direct camera to a permanent one assigned by the VPN and works
Thank you all for your help
