A modern video surveillance system rarely works without IP cameras connected to a wireless network. During initial setup, especially in the corporate segment or when using specialized NVR recorders, it's often necessary to manually enter a unique device ID. This is where users often face the question of how to find the camera's WiFi MAC address if the sticker on the camera's housing has been lost and the packaging has long been discarded.
Finding this 48-bit identifier is necessary not only for whitelisting a device but also for diagnosing connection issues. Without knowing the physical address, it's difficult to determine whether the router can even see the new device or whether the problem lies in the DHCP settings. There are several proven ways to obtain this information, from simply inspecting the device's case to using the command line.
In this guide, we'll cover both software and hardware detection methods. We'll cover using network scanners, analyzing ARP tables, and working with vendor-specific software. It's important to understand that these methods may vary slightly depending on your computer's operating system and router model.
What is a MAC address and why is it needed for an IP camera?
A MAC address (Media Access Control Address) is a unique identifier assigned to a network interface during manufacturing. Unlike an IP address, which can change dynamically, this code is hardcoded into the hardware and serves to identify the device at the data link layer of the OSI model. For a WiFi camera, this is the primary way the router distinguishes the video stream from other devices on the network.
Physical address It consists of 12 hexadecimal digits, separated into pairs. The first six characters identify the equipment manufacturer (OUI), and the second six are the unique serial number of the interface. Knowing this code, a network administrator can accurately determine which device is consuming bandwidth.
In the context of security systems, knowledge of the MAC address is critical to the implementation of security policies. MAC filteringIf you block your router from granting access to all devices except those on the allowed list, even with your WiFi password, an attacker won't be able to connect their camera to your network. This identifier is also used to assign a static IP address so that the camera is always accessible via the same path after a router reboot.
⚠️ Note: MAC addresses are case-sensitive in some older systems, although modern routers typically ignore the difference between AF and af. When entering them manually, be careful not to confuse the number 0 with the letter O.
Find the address on the device body and in the documentation
The most obvious, yet often overlooked, method is a physical inspection. On most camera models, whether Hikvision, HiWatch or DahuaThere's an information sticker on the back or bottom of the case. It contains the serial number, model, and a string labeled "MAC" or "MAC Addr."
This address is often duplicated as a QR code for quick addition to a mobile app. Scanning this code with a smartphone camera can immediately display the required information in the scanner app. If the sticker has worn off, try checking the original box or instructions, where specific information about the specific item is sometimes printed.
- 🔍 Inspect the bottom of the camera body in good lighting.
- 📱 Scan the sticker's QR code using the Camera app or a QR scanner.
- 📦 Check the warranty card or box, if you still have them.
In some cases, especially with outdoor dome cameras, the sticker may be located under the pan/tilt mechanism or inside the protective housing. If the device is already mounted at a height, this method may be difficult to implement without dismantling it, so software-based solutions may be necessary.
Using the router interface to search for devices
The most reliable software method is to view the client list in your router's web interface. Since the camera is connected to WiFi, it will definitely appear in the list of active connections. You'll need access to the router's admin panel, usually accessible at 192.168.0.1 or 192.168.1.1.
After logging in, find a section that may be called "Client List," "DHCP Server," "Wireless Status," or "Network Map." In the table of connected devices, look for names that contain the camera brand (e.g., IPCAM, Hikvision) or unknown devices. The 48-bit code you're looking for will be listed next to the name.
For ease of comparison, below is a table showing where to find this information in popular router models:
| Router model | Menu section | Tab name |
|---|---|---|
| Keenetic | My Networks and Wi-Fi | List of devices |
| MikroTik | IP -> DHCP Server | Leases |
| TP-Link | Wireless | Wireless Statistics |
| Asus | Network map | Clients |
If there are many devices in the list, try temporarily unplugging the camera and refreshing the router page again. The missing line will be the device you're looking for. This is especially helpful if the camera hasn't been configured yet and has a default name.
Scanning your network with Advanced IP Scanner
If access to the router is limited or the interface is too complex, use specialized software to scan the local network. Advanced IP Scanner It's free, requires no installation, and works on all versions of Windows. It allows you to quickly scan a range of addresses and see all active devices.
Launch the program and click the "Scan" button. In a few seconds, you'll receive a complete list of devices on your subnet. The "Manufacturer" column often displays the camera's brand name, making it easier to find. The MAC address is displayed in the corresponding column.
For a more in-depth analysis, you can use the port search function. CCTV cameras often use specific ports (e.g., 80, 554 for RTSP, 8000). Filtering by open ports will help weed out computers and phones, leaving only video equipment.
☑️ Pre-scan check
The advantage of this method is that it displays devices even if they haven't received an IP address via DHCP (as long as they have a Link-Local address), although this is less relevant for WiFi. The program also allows for remote shutdown or wake-on-LAN, which can be useful for managing peripherals.
Using the command line and the ARP table
For users who prefer native Windows tools without installing third-party software, the command line is ideal. The ARP (Address Resolution Protocol) maintains a table of IP address mappings to physical addresses. To view this table, you must first "query" the network.
Open the command prompt by typing cmd in the Start menu. First, ping the broadcast or gateway address to refresh the cache. Then, enter the command to display the table:
arp -aIn the list that opens, find your camera's IP address (if known) or scan the list for unknown devices. The output format will show the IP address and its corresponding physical address on the right. If the camera is online but not visible, try pinging the entire address range first.
⚠️ Note: The ARP table is dynamic and is cleared when the router reboots or the entry lifetime expires. If the camera hasn't transmitted data for a long time, it may no longer be in the cache. Use ping to reactivate the entry.
For Linux and macOS the command is similar, but the syntax may differ slightly (often used ip neigh or simply arp -a). This method is good for its speed and lack of need for additional software.
Search through proprietary software and mobile applications
Many manufacturers provide tools for searching cameras online, such as SADP Tool for Hikvision or ConfigTool For Dahua. These programs operate at the data link level and find devices even if their IP address is on a different subnet. This is a powerful tool for initial setup.
Information can also be found in mobile applications such as Hik-Connect, DMSS or Tuya SmartGo to the device settings within the app and select "Device Information" or "About Camera." The WiFi module's MAC address is often listed there (sometimes it differs from the LAN port address if the camera is wired and has WiFi support).
- 📲 Download the camera manufacturer's official app.
- 🔌 Add a camera to the app (if it hasn't been added yet).
- ℹ️ Go to Settings → About device / Information.
A special feature of WiFi cameras is that they can have two MAC addresses: one for the wired interface (Ethernet) and one for the wireless module. Make sure you copy the WiFi address when setting up a wireless connection. In specifications, these are often referred to as MAC (LAN) and MAC (WLAN).
Why might LAN and WiFi addresses differ?
The camera contains two different network controllers. One is responsible for the wired connection, the other for the radio module. Each controller has its own unique factory ID, so the addresses will differ, usually in the last digit or group of digits.
Common problems and solutions when searching
One common problem is when the camera is connected to one subnet (e.g., 192.168.1.x) and the computer is on another (192.168.0.x). In this case, direct scanning or pinging will not yield results. The solution is to temporarily change the IP address of the computer's network card to an address in the camera's subnet.
Another complication arises when using guest WiFi networks. Many routers isolate guest network clients from each other (AP Isolation). In this mode, the camera physically won't be able to "see" your computer for configuration, and scanners won't find the device. Use the main network for configuration.
It's also worth considering that some cameras have a static IP address by default, which may conflict with your router's address or be in the wrong range. Using utilities like SADP Tool allows you to change the IP address even in this case, as they bypass the default OS network settings.
FAQ: Frequently Asked Questions
Is it possible to change the MAC address of a CCTV camera?
In most standard IP cameras, changing the MAC address via software is impossible, as it is hardcoded into the network card chip at the factory. However, some advanced Linux-based models or specialized video recorders allow this to be done via console commands, but this requires extensive technical knowledge and may void the warranty.
What should I do if the MAC addresses of two cameras are the same?
This is a critical error that will lead to network conflicts and unstable operation of both cameras. This is extremely rare and usually indicates a defective batch or the use of cheap clones. The only solution is to replace the device or reflash the firmware, if the manufacturer offers this option.
Is the camera's MAC address visible over the Internet?
No, the MAC address only works within the local network (layer 2). When data travels through the router to the global network, this address is replaced by the router's address. It's impossible to find the camera's MAC address remotely; only through a local connection or the camera's interface if it forwards this information to the cloud.
How do I find the MAC address if the camera won't connect to WiFi?
If the camera doesn't connect, software methods may not work. In this case, your only options are to physically inspect the sticker, use a wired connection (if there's a LAN port) to access the web interface, or reset the camera to factory settings (Reset), after which it may become visible using standard search tools.
