How To Record Surveillance Camera To Computer

Last Updated: by

To record a security camera to a computer, connect a compatible IP camera to the same local network and configure recording software to save its stream. An Ethernet connection provides access; it does not start recording automatically. Keep the computer and recording application running.

You can connect a single camera to your computer directly or set up multiple cameras using a Wi-Fi router. Regardless of the setup, ensure all devices are powered on and connected through the proper adapters and equipment.

Things to Know

  • Connecting the network cable of the security camera to your computer can help you stream and download footage directly.
  • That said, the camera and computer must fall under the same network. Therefore, you might have to configure the IP addresses of either device accordingly.
  • You can plug in a security camera directly to your computer or go through a Wi-Fi router and PoE switch. 
  • You can configure the IP address of your computer manually. This is by using the network settings or system preferences. 
  • Alternatively, you can reconfigure the IP address of the security camera. However, you must use an IP config tool compatible with your camera. 
  • A computer can act as a software NVR when its camera compatibility, storage, performance and uptime are suitable. A dedicated recorder is simpler if you do not want to maintain a recording computer.

Setting Up A Surveillance Camera for Computer Recording

Before setting up your security camera directly with your computer, you must prepare the necessary components. These are:

  • An IP-based security camera
  • A computer or laptop
  • Cat6 network cables
  • Wi-Fi router (with or without internet access)
  • PoE Injector or Switch (if your cameras support PoE)
  • A compatible PoE splitter only if a non-PoE camera needs separate DC power from a PoE source
  • The camera’s supported power supply, or a PoE source meeting its required standard and power budget

After gathering these, you can connect your security camera to your computer. However, there are two methods to achieve this:

  1. By directly connecting your security camera to your computer (No Wi-Fi router or PoE Switch Required)
  2. Connecting via a Wi-Fi router (with or without a PoE Switch)

As you can see, the steps can change slightly based on whether you want to connect via a PoE injector/switch. However, these are easy to follow through as long as you understand the differences between PoE and non-PoE switches. 

  1. Connecting Security Camera Directly to a Computer (Without a Router)
  1. First, install the security camera in the location you want to monitor.
  2. Power the camera with its approved supply. For a PoE camera, put a compatible injector between the computer and camera: the computer connects to its data input and the camera to its PoE output. A PoE splitter belongs at a compatible non-PoE camera, not at the computer to create power.
  3. Connect the data path to the computer’s Ethernet port. An ordinary computer Ethernet port does not supply PoE. Check the injector’s input/output labels and never connect a passive power output without confirming compatibility.
  4. Find the camera’s actual current IP address using its supported discovery tool or, on a routed network, the router’s device list. A printed default address may differ from the address assigned by DHCP.
  5. Alternatively, you can try downloading an IP config tool to scan your network and retrieve the IP address of the security camera.  
  6. After you note down the security camera, open a web browser and type in this IP address. You can also open your VMS software and see if the new camera is detected. 
  7. If discovery shows the camera on a different subnet, you may need to change your computer’s IP address temporarily. Record its existing Ethernet settings first. Lack of a browser page alone does not establish an address fault; some cameras require a client or initialization tool.
  8. After you change the IP address of your computer, open up the browser and type in the IP address of your security camera again. If you have a VMS, you can instead open it up and check if the new camera is added to the network.
  9. Log in using the credentials you created during initialization, or follow the manufacturer’s first-use activation process. Change any supplied default password before normal use; do not assume every camera has printed default credentials.
  10. If your login details are correct, the client app will show some options or a direct live feed from your security camera. 
  11. Add the camera to compatible recording software and select its local recording destination and schedule. A live-view button or a browser snapshot is not continuous recording. The linked example shows one way to record footage locally on your computer; use instructions for your actual software.

How to Change the IP Address of Your Windows or Mac

  1. For the classic Windows Ethernet settings, open Control Panel. On Windows 11, you can instead use Settings → Network & internet → Ethernet → IP assignment → Edit.
  2. Head over to the “Network and Sharing.” You can type this in the search bar for quick access.
  3. Then navigate to “Change Adapter Settings” at the top left.
  4. Select the Ethernet adapter connected to the camera. You do not normally need to disable Wi-Fi; if you temporarily disable it to diagnose overlapping networks, restore it when finished.
  5. After that, right-click on “Ethernet” and navigate to “Properties.”
  6. Double-click on the IP protocol version of your security camera. Usually, it’s “Internet Protocol Version 4 (TCP/IPv4).
  7. Then enable “Use the following IP Address” to set one up manually.
  8. Choose an unused host address in the camera’s subnet. For example, with camera 192.168.50.10 and mask 255.255.255.0, the computer could use 192.168.50.20 if unused. The last-octet shortcut applies to that /24 example, not every subnet.
  9. Enter the subnet mask or prefix specified for the camera network; do not rely on an automatically suggested mask. For the example above, use 255.255.255.0 or prefix length 24.
  10. Save the settings and test access. When returning the adapter to your usual network, restore its recorded settings, normally Automatic (DHCP), unless your network requires a static address.

On a current Mac, open System Settings → Network → Ethernet → Details → TCP/IP, then choose the required Configure IPv4 mode. Save the existing settings and restore them afterward. The video below shows a Mac example; menu names vary by macOS version.

2. Connecting a Security Camera to a Computer (Via a Wi-Fi Router)

You can use a Wi-Fi router to bridge the gap between your security camera and computer. This method is preferred since you can retain internet access and also connect multiple cameras at once. 

Use a router’s LAN ports and add a switch if more ports are needed. Use a PoE switch or injector only where camera power requires it. Discover cameras with their manufacturer’s supported tool; Dahua Config is a Dahua example, not a universal tool.

So here’s how to set this up:

  1. First, install your security camera and provide power to it. 
  2. If you have a PoE camera, connect the CAT6 cable from the security cameras to your PoE switch/injector. Then, power on the PoE switch. 
  3. After that, connect the “Uplink” port on your PoE switch to an ethernet port in your Wi-Fi router. Ensure the router is powered on.
  4. Then, connect your Wi-Fi router and computer via another CAT6 network cable. This step isn’t necessary if you can wirelessly connect to the same Wi-Fi network on your computer.
  5. Discover and initialize each camera with its supported tool. DHCP is usually the easiest starting point; use a router reservation or a planned static address if the recording software needs a stable address. Avoid duplicates and addresses assigned to other devices.
  6. Save your changes and refresh.
  7. Add the initialized cameras to the recording application using its supported integration or stream settings. Check codec support, select a recording folder and schedule, then verify that new video files are actually created.

Set the Recording Schedule and Prove It Works

In the Reolink Client, supported non-battery devices use the client’s Local Record settings and Local Record Schedule. Choose continuous or motion recording, set the saved-file location, and review overwrite and stream settings. This is separate from a camera’s own microSD recording schedule.

Keep the client running and the computer awake; Reolink states that PC sleep stops client recording. Other VMS packages may run a background service, so follow that application’s startup and recovery instructions rather than assuming every open window behaves the same way.

Record a short test, locate the file on the computer and play it back. Then test the intended schedule, a computer restart and the chosen disk-full behavior. For motion recording, walk through the scene and confirm the saved clip captures the approach. Downloading an old clip from an NVR is a backup task, not a new recording schedule.

Verdict

It is possible to use your computer as an NVR. However, you must connect the cameras to the same network as the computer and configure the IP addresses accordingly. 

In this way, you can connect a single camera directly or use a Wi-Fi router and PoE switch to connect an entire security camera system. 

For ongoing recording, use a computer configured for that role, with sufficient storage and recovery after restarts. A dedicated NVR can reduce maintenance, but a properly supported software NVR is a valid long-term option.
