Finding the IP camera UID is essential for setup, troubleshooting, or integration with surveillance systems. This guide walks you through multiple methods—using software tools, mobile apps, and manual checks—so you can quickly locate your camera’s unique ID. Whether you’re a home user or IT professional, these clear steps will help you retrieve the UID efficiently.
Quick Answers to Common Questions
Can I change my IP camera UID?
Answer: Generally, no—UIDs are factory-assigned and hardcoded. However, some advanced systems allow renaming or regenerating IDs through NVR software or firmware tools. Always check your manufacturer’s guidelines before attempting changes.
Is the UID the same as the MAC address?
Answer: Not exactly. While both are unique identifiers, the UID is a proprietary serial number used by the manufacturer, while the MAC address is a hardware-level network identifier. They serve different purposes but are often listed together on labels.
What if my camera has no UID?
Answer: Rare, but possible if the device was refurbished or cloned. Try accessing the web interface or using manufacturer software. If nothing works, contact support—they may issue a replacement or recovery method.
Do I need the UID for local recording?
Answer: No. Local recording (via SD card or NVR) works without entering the UID. However, UID is required for cloud services, remote viewing, or firmware updates.
How long is a typical IP camera UID?
Answer: Usually 8 to 15 alphanumeric characters (letters and numbers). Format varies by brand—check your manual for specifics.

- Device Identification: Helps networks assign correct settings and permissions.
- Firmware Updates: Some manufacturers require the UID to push updates or activate licenses.
- Remote Access Setup: Used when linking the camera to cloud services or NVR/DVR systems.
- Troubleshooting: Support teams often ask for the UID to diagnose issues accurately.
If you’ve ever tried to connect your camera to a monitoring app and failed, the UID might be missing or incorrectly entered. That’s why finding it early saves time and frustration.
Method 1: Check the Physical Label on Your Camera
The quickest way to find your IP camera UID is by looking at the device itself. Most manufacturers print identifying information directly on the camera housing or included accessories.
Where to Look
- Bottom or Side Panel: Flip the camera over or remove the mounting bracket. You’ll often see a sticker with model number, MAC address, and UID.
- Power Adapter or Cable: Some brands include the UID on the power supply or Ethernet cable label.
- Original Packaging: If you still have the box, check the barcode or info sheet inside.
What to Look For
Search for phrases like:
- UID: Example: “UID: ABC123XYZ”
- SN: Serial Number (often interchangeable with UID)
- MAC Address: While different, sometimes listed near the UID for reference
Example label text:
Model: DS-2CD2143G0-I
UID: 6F7E8D9C0A
MAC: 00:1B:44:11:3A:B7
Power: DC12V 1A
If you see a string of alphanumeric characters (usually 8–15 digits), that’s likely your UID.
Method 2: Use the Camera’s Web Interface
If you can access your camera through a browser, you can usually find the UID in its settings menu. This works for most brands including Hikvision, Dahua, Lorex, and Amcrest.
Step-by-Step Instructions
- Connect to the Same Network: Ensure your computer or phone is on the same Wi-Fi or LAN as the camera.
- Find the Camera’s IP Address: Open Command Prompt (Windows) or Terminal (Mac/Linux) and type
arp -a. Look for entries matching your camera’s brand name or MAC prefix. - Open a Web Browser: Type the camera’s IP address into the address bar (e.g.,
http://192.168.1.100). - Log In: Enter username and password (default is often admin/admin or admin/password).
- Navigate to System Settings: Look for tabs like “System,” “Settings,” or “About.”
- Locate Device Info: Scroll down to find fields labeled “UID,” “Serial Number,” or “Device ID.”
Tip: If you forgot the login credentials, try resetting the camera using the small reset button (usually behind a pinhole). Hold it for 10 seconds until the lights blink—this restores factory defaults.
Method 3: Use Manufacturer Software Tools
Many IP camera brands offer dedicated software that automatically discovers cameras on your network and displays detailed info—including the UID.
Popular Software Options
- iVMS-4200 (Hikvision): Free desktop app that scans for Hikvision cameras and shows UID under device properties.
- DSS Pro (Dahua): Centralized management tool with full device inventory and identifiers.
- Lorex Insight App: Mobile app that lists all connected Lorex cameras with UID and status.
- Amcrest View Pro: Desktop software for Amcrest cameras with easy UID lookup.
How to Use iVMS-4200 (Example)
- Download and install iVMS-4200 from Hikvision’s official website.
- Launch the app and click “Add Device.”
- Select “Auto Scan” and wait for cameras to appear.
- Right-click your camera > “Properties” > “Device” tab.
- Copy the “UID” field value.
This method is especially useful if you manage multiple cameras or use an NVR.
Method 4: Mobile Apps for UID Retrieval
Modern IP cameras often come with companion mobile apps that simplify setup and management. These apps typically show the UID during initial configuration.
Top Apps by Brand
- Hik-Connect / Hikvision: Shows UID in device details after adding the camera.
- Dahua DMSS: Displays UID when viewing live feed or device info.
- Amcrest Smart Home: Lists UID under camera settings.

- Look for your camera in the list (often named by model or location).
- Tap the device > scroll down—some versions show “Serial” or “ID” fields.
Limitation: Not all cameras expose UID over standard protocols. Results vary by manufacturer.
Method 6: Check the NVR/DVR System
If your IP camera is connected to a Network Video Recorder (NVR) or Digital Video Recorder (DVR), the UID might be stored there.
Steps to Retrieve UID from NVR
- Access the NVR’s web interface or control panel.
- Go to “Camera Management” or “Device List.”
- Select your camera from the grid.
- View “Device Info” or “Properties”—the UID should be displayed.
This method is ideal if the camera is already integrated into a surveillance system but you don’t have direct access to it.
Troubleshooting Common Issues
Even with the right tools, you might run into roadblocks. Here’s how to solve them.
Issue 1: Can’t Log Into Camera Web Interface
Solution: Reset the camera. Locate the reset button (small hole on the side/bottom), press and hold with a paperclip for 10–15 seconds until LEDs flash. Wait 2–3 minutes for reboot. Then try logging in with default credentials.
Issue 2: UID Field Appears Blank
Solution: Firmware corruption may hide the UID. Update firmware via manufacturer’s website or software. Alternatively, reflash the camera using recovery mode (consult your manual).
Issue 3: Multiple Cameras Show Same UID
Solution: This indicates duplicate IDs—likely due to cloning or misconfiguration. Assign unique UIDs via the NVR or software. Most systems allow renaming or reassigning device IDs.
Issue 4: No Devices Detected by Scanning Tool
Solution: Ensure both devices are on the same subnet. Disable firewalls temporarily. Try switching between wired and wireless connections.
Issue 5: UID Too Long or Contains Special Characters
Solution: Some systems use Base64 encoding or checksums. Copy the full string as-is—it’s valid. Avoid truncating or altering it.
Best Practices for Managing Your IP Camera UID
Once you’ve found your UID, keep it safe and organized. Here’s how:
- Write It Down: Store the UID in a secure notebook or password manager.
- Label Your Cameras: Use physical tags or digital spreadsheets to map UIDs to locations (e.g., “Back Door – UID: AB12CD34”).
- Update Regularly: After firmware updates or replacements, verify the new UID.
- Avoid Public Sharing: Never post UIDs on social media or forums—they can aid attackers.
Save device settings so you can recover quickly if needed.
