Finding the CID (Camera Identification Number) of an IP camera is essential for setup, monitoring, and security management. Whether you’re using a DVR/NVR system or standalone device, this guide walks you through simple methods to locate your camera’s unique ID. You’ll learn how to use network tools, access web interfaces, and interpret device settings—all explained clearly for beginners and tech-savvy users alike.
Have you ever tried setting up an IP camera but got stuck looking for its unique identification number? That number—known as the CID (Camera ID)—is crucial when linking cameras to DVRs, NVRs, or remote viewing apps. Without it, your system might not recognize the device, making installation frustrating and incomplete.
This complete how-to guide explains exactly how to find out CID of IP camera, whether you’re using a smart home system, business surveillance setup, or personal security solution. We’ll walk through every method from simple browser checks to advanced network scans—so no matter your technical skill level, you’ll master finding that elusive CID.
By the end, you’ll know:
– What CID really stands for
– Where to look first
– How to verify your findings
– What to do if things go wrong
Let’s get started!
Quick Answers to Common Questions
Tip/Question?
Can I use the MAC address instead of CID?
Answer: Not always. While MAC addresses are unique hardware IDs, many DVR/NVR systems specifically expect the manufacturer-assigned CID (often the serial number). Using the wrong identifier will result in connection failures.
Tip/Question?
Why does my camera show two different serial numbers?
Answer: Some cameras have one printed on the label (used for warranty) and another in firmware (used for system integration). Always use the one displayed in the camera’s web interface—it’s the active CID recognized by recording systems.
Tip/Question?
Is it safe to share my camera’s CID online?
Answer: Generally no. Sharing CIDs along with IP addresses or login details can allow attackers to access your live feed or tamper with recordings. Keep this information private and encrypted.
Tip/Question?
Do all IP cameras have a web interface?
Answer: Yes—most professional-grade IP cameras include one. Consumer models (like Wyze or Ring) often rely on cloud-only access and lack local web servers, so CIDs may only be visible through companion apps.
Tip/Question?
What if my camera has no visible label?
Answer: Try unboxing instructions or search “[model number] label location” online. Alternatively, access the web interface first—the CID is usually listed in system info before you even need the physical label.
Understanding CID: What Is It and Why Does It Matter?
Before diving into steps, let’s clarify what “CID” means in this context. In IP camera terminology, CID refers to the unique identifier assigned to each camera, allowing central systems (like DVRs or cloud platforms) to distinguish between multiple devices. Think of it like a social security number for your camera.
Different manufacturers use various terms: some call it “Device ID,” others “Serial Number,” or even “MAC Address.” But regardless of naming, the purpose remains the same: to uniquely identify your camera within a network or recording system.
For example:
– In **Hikvision** systems, the CID is often a combination of model code + serial number.
– **Dahua** cameras may display a CID under “System Information.”
– **Axis Communications** uses a similar format but includes region-specific prefixes.
Knowing your CID helps with:
– Linking cameras to DVR/NVR software
– Remote access via mobile apps
– Firmware updates
– Troubleshooting connectivity issues
Now that we understand why CID matters, let’s explore practical ways to find it.
Step-by-Step: How to Find Out CID of IP Camera

Follow these clear steps based on your setup type. Each method works for most modern IP cameras unless noted otherwise.
Method 1: Check the Physical Label
Many IP cameras have a sticker on the back, bottom, or side containing key details including the CID.
What to look for:
– Serial number (often labeled “SN”)
– Model number (e.g., DS-2CD2085FWD-I)
– MAC address (sometimes mistaken for CID)
Example label text:
Model: DS-2CD2085FWD-I | SN: H2AB123456789 | MAC: 00:1A:2B:3C:4D:5E
In many cases, the serial number (SN) doubles as the CID. However, always confirm this matches what your DVR/NVR expects—some systems require only part of the SN.
Method 2: Access the Camera’s Web Interface
Almost all IP cameras include a built-in web server. Here’s how to reach it:
Step 1: Connect to the camera’s network
– Plug the camera into power and Ethernet cable (or connect via Wi-Fi if supported).
– Ensure your computer or phone is on the same local network.
Step 2: Find the camera’s IP address
Use one of these tools:
– **Router admin page**: Log in to your router (usually at 192.168.1.1), then check “Connected Devices” or “DHCP Client List.” Look for unfamiliar device names or MAC addresses matching your camera’s label.
– **Fing app** (iOS/Android): Scans your network instantly and shows all connected devices with IPs and hostnames.
– **Angry IP Scanner** (Windows/Mac): Free tool that lists live hosts on your subnet.
Once you have the IP (e.g., 192.168.1.105), open a web browser and enter:
http://192.168.1.105
Step 3: Log in to the camera
Default credentials are usually:
– Username: admin
– Password: admin, 12345, or blank
(Check your manual—some newer models disable default passwords.)
Step 4: Navigate to System Info
Look for sections like:
– Setup > About Device
– Configuration > System > General
– Maintenance > Device Info
Here you’ll see:
– Device Name
– Manufacturer
– Model
– **Serial Number (CID)**
Method 3: Use Your DVR or NVR Software
If your camera is already registered with a DVR/NVR, the CID may be visible there.
Steps:
1. Open the DVR/NVR client software (e.g., Hik-Connect, iVMS-4200, or vendor-specific app).
2. Go to “Device Manager” or “Camera List.”
3. Select your camera from the list.
4. Right-click > Properties > Basic Info.
The CID should appear next to “Device ID” or “Serial Number.”
> 💡 Pro Tip: Some systems auto-detect CIDs during initial setup. If yours didn’t, try re-adding the camera manually using its IP and default credentials.
Method 4: Scan Your Network with Discovery Tools
When you don’t know the camera’s IP or can’t access its interface, network scanners help.
Recommended tools:
– **Fing** – User-friendly, real-time alerts
– **Advanced IP Scanner** – Lightweight, fast
– **Nmap** – Command-line powerhouse (for tech users)
How to use Advanced IP Scanner:
1. Download and install from official site.
2. Run as administrator.
3. Click “Scan” on your subnet (e.g., 192.168.1.0/24).
4. Wait for results.
5. Look for entries labeled “IP Camera,” “Surveillance,” or matching your model name.
6. Double-click to open web interface directly.
Most scanners also show MAC addresses—compare them to the label on your camera to confirm identity.
Method 5: Reset the Camera (Last Resort)
If all else fails and you’re okay losing current settings:
Reset procedure:
1. Locate the reset button (usually tiny hole on side/back).
2. Press and hold for 10–15 seconds until LED blinks.
3. Reconnect to network.
4. Access default IP (often 192.168.1.64 or printed on label).
5. Log in with defaults and check System Info again.
> ⚠️ Warning: Resetting erases custom settings like motion detection zones or scheduled recordings.
Troubleshooting Common Issues
Still can’t find your CID? Try these fixes:
Issue: Can’t access camera web interface
– Confirm correct IP address
– Disable firewall temporarily
– Try different browser (Chrome/Firefox)
– Verify username/password
Issue: Multiple cameras showing same CID
– Likely duplicate serial numbers from factory error
– Contact manufacturer support for replacement
Issue: CID not appearing in DVR list
– Reboot both camera and DVR
– Update DVR firmware
– Manually add camera using IP + credentials
Issue: Camera not connecting to network
– Check Ethernet cable
– Try static IP assignment
– Test with PoE switch if applicable
Remember: Always document your CIDs immediately after setup—you’ll thank yourself later during maintenance or expansion.
Best Practices for Managing IP Camera CIDs
Once you’ve found your CID, keep it safe and organized:
– **Label physically**: Write the CID on tape near the camera or inside ceiling tiles.
– **Store digitally**: Save in a password manager or spreadsheet with notes (location, model, last update date).
– **Update regularly**: After firmware upgrades, CIDs sometimes change—recheck periodically.
– **Secure access**: Change default login credentials immediately to prevent hacking.
Also consider using ONVIF-compliant cameras if you plan to mix brands—they standardize CID handling across devices.
