Modern video surveillance systems require precise network configuration for stable operation. Users often encounter situations where they need to access a device's web interface or configure port forwarding, but the device's current local network address is unknown. This can occur after resetting the router, changing providers, or during initial installation of the equipment.
Search IP addresses Network coordinates are a critical step in integrating a camera into a home or office security system. Without this parameter, it's impossible to set up remote viewing over the internet or connect the device to a video recorder (NVR). There are several proven methods for detecting network coordinates, ranging from specialized software to analyzing routing tables.
In this article, we'll detail the steps to take for various scenarios. We'll explore how DHCP and static addressing work, why network conflicts can occur, and which tools can help you quickly identify a device among dozens of other gadgets. Correctly identifying the address will prevent future connection issues.
Analyzing the client table in the router
The most reliable and universal way to find the IP address of any device on your local network is to access your router's administrative panel. The router acts as a DHCP server, issuing addresses to all connected devices and storing the current list in its memory. You need to log in to the router's web interface, usually accessible at 192.168.0.1 or 192.168.1.1.
After logging in, you should find a section whose name may vary depending on the equipment model. Look for the tabs Client List, "DHCP Server", "Client List" or Network MapThis section displays a complete table of all active connections, including MAC addresses and assigned IP addresses. Find your camera in the list by manufacturer name (e.g., Hikvision, Dahua, TP-Link) or by MAC address, which is often indicated on the sticker on the device body.
Router interfaces are constantly updated, with menu names and settings locations changing. If you can't find the section you need, consult your router's official documentation or look for up-to-date interface screenshots for your specific model.
The advantage of this method is that it shows the exact address currently in use. Even if the camera was configured with a static IP, the router will still know the address from which traffic is coming. This is especially useful if the previous owner or installer configured non-standard network parameters.
⚠️ Note: If the camera is not connected directly to the router, but rather through a second cascaded router or a mesh system, it may not appear on the main router. In this case, you need to look for the IP in the interface of the device to which it is connected physically or via Wi-Fi.
Using network scanners on a PC
If access to your router is limited or you don't want to navigate complex menus, you can use specialized network scanning software. These utilities broadcast requests to all devices on the network segment and analyze the responses. One of the most popular tools is Advanced IP Scanner for Windows.
The detection process is extremely simple: launch the program and click the button "Scan"The app will quickly query the entire address range and return a list of all active devices. You'll see not only the IP address but also the network card manufacturer, which will help identify the camera. For macOS, the utility LanScan or a built-in network analyzer.
- 🔍 Advanced IP Scanner — a free, fast utility that doesn't require installation, ideal for one-time checks.
- 📱 Fing — a popular mobile application for Android and iOS that allows you to scan the network directly from your phone.
- 💻 Angry IP Scanner — a cross-platform, open-source scanner with advanced functionality for advanced users.
It's important to understand that some cameras may not respond to standard ping requests for security reasons or due to power-saving settings. In such cases, the scanner may show the device as "inactive" even if it's connected. However, if the camera is broadcasting a video stream, it will almost certainly be visible in the list of active connections.
Search via the command line (CMD)
For users who prefer not to install unnecessary software, the Windows operating system provides built-in diagnostic tools. The command line allows you to view the ARP table, which maps IP addresses to physical MAC addresses of devices with which your computer has recently communicated.
Open the command prompt by typing cmd in the Start menu. First, you need to refresh the cache by sending a broadcast request. Enter the command arp -a and press Enter. You'll see a list of addresses. The problem is that there could be hundreds of entries, and without knowing the camera's MAC address, it's difficult to find the desired IP address.
ping 192.168.1.255Before entering the command arp -a you can run the command ping 192.168.1.255 (replacing the last digit with the broadcast address of your subnet) to "wake up" all devices on the network and force them to respond. After this, more entries will appear in the ARP table. Look for lines where the MAC address begins with the prefix of a well-known camera manufacturer.
This method requires a basic understanding of network addressing. You must know your subnet mask to correctly construct the query. If you are unsure of what you are doing, it is better to use the graphical interfaces of the scanners described above, as entering a command incorrectly can result in incomplete results.
What is an ARP table?
ARP (Address Resolution Protocol) is a protocol used to convert an IP address to a physical MAC address. The ARP table is stored in the computer's RAM and is updated dynamically. It is not persistent and is cleared upon reboot or when the entry expires.
Specialized software from the manufacturer
Major manufacturers of video surveillance systems such as Hikvision, Dahua, Axis And Ubiquiti, release their own utilities for searching and configuring their devices. These programs operate at a deeper level than standard network scanners and can find cameras even if they are on a different subnet or have an IP address incompatible with the PC's current network.
For example, for equipment Hikvision the program is used SADP Tool (Search Devices Network Protocol). It works regardless of the computer's IP address settings. The utility simply listens on a special port and identifies all devices of the brand in the local segment. Similarly, for Dahua there is a utility ConfigTool, and for Axis — Axis Camera Management.
| Brand | Name of the utility | Peculiarities |
|---|---|---|
| Hikvision | SADP Tool | Works without installation, changes IP, resets password |
| Dahua | ConfigTool | Search by MAC, mass firmware update |
| Ubiquiti | Device Discovery | Finding UniFi devices on the network |
| ONVIF | ONVIF Device Manager | Universal program for any ONVIF cameras |
Using the camera's native software is often the only way to change the camera's IP address if it conflicts with your router's address. For example, if the camera has a static address. 192.168.1.64, and your router distributes addresses in the range 192.168.0.xA standard scanner won't detect it. A specialized utility will allow you to "reprogram" the camera to the desired range.
⚠️ Important: When using manufacturer utilities to change the IP address, ensure the new address is not already in use by another device. IP address conflicts will result in unstable network operation for both devices.
Finding an address using a mobile app
Modern IP cameras are often configured via mobile applications using the protocol P2P or scanning a QR code, and the user may not know the device's real IP address for years. However, many video surveillance apps (for example, gDMSS, Hik-Connect in LAN mode, V380) have a device settings section where technical information is displayed.
Go to the settings for a specific camera within the app. Find the item Device Information, Network Settings or About the camera. The local IP address, MAC address, and connection status are often listed there. This method only works if your smartphone and camera are on the same Wi-Fi network.
If the app only displays the "Online" status without any details, try searching for the device editing function. Tapping the pencil or editing button sometimes reveals hidden fields with network parameters. This is especially true for budget Chinese cameras that use cloud services.
Troubleshooting camera visibility issues
There are situations where the camera is physically connected to Wi-Fi (the indicators are lit), but none of the above methods allow it to be detected. The first possible cause may be Wi-Fi client isolation (AP Isolation). This feature on the router prevents devices connected via a wireless network from exchanging data with each other.
Check your router's wireless settings. If "Client Isolation" or "AP Isolation" is enabled, disable it. This will allow the computer and camera to "see" each other. Also, make sure the camera and PC are on the same subnet. If "Guest Wi-Fi" is enabled on your router, devices on the guest network will not be able to see devices on the main network.
Another common problem is the camera working in the mode AP (Access Point)In this mode, the camera creates its own Wi-Fi network for initial setup. Until you switch it to client mode (Station) and connect it to your router, it won't appear in the router's client list. Connect to the camera's own Wi-Fi network (the name is usually indicated on the sticker) and use a browser to go to 192.168.1.1 or as specified in the instructions to set up a connection to your Internet.

Frequently Asked Questions (FAQ)
Is it possible to find the IP address of a camera if it is connected to a different router?
No, it's impossible to directly find the local IP address of a camera located behind another router from the external network without prior configuration. Local addresses (starting with 192.168.xx) are not routable on the internet. For external access, you need to configure port forwarding or use cloud P2P services that hide the real IP.
What should I do if the camera's IP address keeps changing?
This means the camera is set to obtain an address automatically (DHCP), and the router assigns it a new one each time. To fix the address, you need to either enter a static IP address (e.g., 192.168.1.150) in the camera's settings, or find the "Static DHCP" or "Address Reservation" function in the router settings and bind the camera's current MAC address to the desired IP address.
Is it safe to change a camera's IP address using a scanner?
Yes, this is standard procedure. However, critical Don't specify an address that's already in use by another device (computer, phone, printer), otherwise a conflict will occur and both devices will lose network connectivity. Use addresses outside the router's DHCP pool range (for example, if the router assigns 100 to 200 addresses, assign 50 to the camera).
How can I find out my IP address if I forgot my router password?
If you can't log into your router, try resetting it to factory settings by pressing the Reset button (usually for 10-15 seconds). This will reset the password to the default one (indicated on the sticker), and you'll be able to log in and view the client list. You can also try the default login and password combinations if they haven't changed.
