A Windows PC screen recorded as a channel on a Dahua NVR, with sound, camera name and time

✓ Tested

Tested on a real Dahua NVR in August 2026. Every NVR screenshot on this page comes from that test.

How it works

Three parts and one open standard. Nothing is installed on the recorder.

Your Windows PC

Screen2ipcam captures the screen (or one window) and encodes it as H.264, with the PC sound if you want it.

Your network

It answers on ONVIF port 8000 and streams over RTSP port 554, exactly like an IP camera.

Your Dahua

Adds the PC as one more channel, then records, searches and exports it with the cameras.

The values you will need

Copy them from the Screen2ipcam window on the PC. PC-IP is the address of that PC.

ONVIF port: 8000
RTSP port: 554
User / password: admin / admin (change it in Users)
Main stream: rtsp://PC-IP:554/screenlive
Sub stream: rtsp://PC-IP:554/screensub
Discovery: WS-Discovery · UDP 3702

Step by step

Prepare the PC

Install Screen2ipcam on the PC whose screen you want to record (Windows 7 SP1 to 11, or Windows Server).
Give the PC a fixed IP address, or a DHCP reservation on the router, so the recorder never loses it.
In the Video tab choose the screen, the resolution, the frame rate and the bitrate (see the table below).
When Windows asks, allow Screen2ipcam on private networks. Ports 8000 and 554 must be open.

Screen2ipcam: main stream for recording and sub stream for the recorder grid.

Open the Camera List

In a web browser: SETTING → CAMERA → Camera List
On the NVR monitor: Main Menu → Camera → Camera List (older firmware: Camera → Registration)

Click Search Device

The PC appears by itself as an ONVIF device on port 8000, named S2C-..., next to the real cameras.

Real test: Search Device finds the PC (192.168.1.206, port 8000, ONVIF) next to two cameras.

Add it, or use Manual Add

Select the PC and click Add. Then edit the channel and type the Screen2ipcam user and password.

No search result? Click Manual Add: Manufacturer ONVIF, the PC IP, RTSP port 554, HTTP port 8000, user and password.

Real test: the channel settings. ONVIF, RTSP port 554, HTTP port 8000, user admin.

Check that it is online

A green status means the NVR is receiving the stream. The type column shows Screen2ipcam.

Real test: the PC added as channel 9, online.

Check the streams and record

The Encode page shows the stream exactly like a real camera: H.264, 1920×1080 at 10 fps for the main stream and 640×360 for the sub stream. Then set the channel to continuous or motion recording in the schedule.

Real test: main stream 1920×1080 at 10 fps, 2000 kbps, sub stream 640×360 at 512 kbps.

Recommended settings

These are the values from our real recorder test. A PC screen changes little, so 10 frames per second is plenty and keeps the bitrate low.

Setting	Main stream (recording)	Sub stream (live grid)
Codec	H.264	H.264
Resolution	1920×1080	640×360
Frame rate	10	10
Bitrate	2000 kbps	512 kbps
PC sound (optional)	G.711, recorded with the video

Watch it wherever you watch your Dahua

Once the PC is a channel on the recorder, it is part of the system like any camera.

NVR monitorLive view, playback and export.

Web browserThe NVR web interface.

SmartPSSDahua client software for Windows.

DMSSThe Dahua app on phones and tablets.

If the channel stays offline

Search Device does not show the PC

Allow UDP 3702 (WS-Discovery) in Windows Firewall, or skip search and use Manual Add with port 8000.

The channel stays red after adding

Edit the channel and re-type the Screen2ipcam user and password. The NVR fills in its own password by default.

Live view is black or freezes

Check that port 554 is open on the PC and try RTSP port Auto or Custom 554.

The PC has a VPN or two network cards

Open the VPN tab in Screen2ipcam and choose the LAN address the NVR should see.

Test the PC on its own

Open rtsp://PC-IP:554/screenlive in VLC. If VLC plays it, the PC side is ready.

Questions and answers

Does it work with Dahua XVRs?

Yes, on XVRs that can add ONVIF IP cameras. The steps are the same.

Is the sound recorded?

Yes. Turn on PC sound in Screen2ipcam (G.711). The NVR records it with the video, like an audio camera.

Can I watch it in DMSS?

Yes. The PC is a normal channel of the NVR, so it appears in DMSS and SmartPSS.

Can I show the camera name and time on the picture?

Yes. Screen2ipcam can draw a camera name and the date and time on the video, as in the picture at the top.

How much does it cost?
