Changing a CCTV camera's IP address is a standard procedure required when setting up a security system on a local network. Owners often encounter address conflicts when two devices attempt to occupy the same digital cell, resulting in signal loss or unstable video streaming. Properly configuring network parameters prevents outages and ensures 24/7 internet access for cameras.
The process may seem complicated at first glance, but understanding the basic principles of how the protocol works DHCP It simplifies the task significantly. You don't need to be a network engineer to reconfigure the device; all you need is some common sense and access to the router's administrative panel. In this article, we'll cover all the details, from finding the current address to assigning a static value.
Modern IP cameras Often come with preset settings that may not be suitable for your specific network configuration. Changing these settings is the first step to creating a reliable video surveillance system that won't crash after a router reboot. Let's look at how to prepare for this process.
Before you start setting up, you need to understand that IP address — This is a unique identifier for a device on the network. Without the correct address, the camera will not be able to transmit data to a DVR, computer, or cloud storage. A single digit error can completely disrupt the entire security system.
Preparing to change network settings
The first step is to gather information about your current network configuration. You need to know the address range your router assigns to ensure you don't exceed it. This information is usually found in the router's documentation or on a sticker on the bottom of the router that lists the default login parameters.
To use this tool, you'll need a computer or laptop connected to the same WiFi network as the camera. Also, prepare the MAC address of the video surveillance device—this is a unique physical identifier often required for assigning a static address. You can find it on the camera's factory label or in the companion app if the camera is already partially configured.
⚠️ Important: Make sure you know your router's administrator login and password. Without this information, you won't be able to change network settings, and it's best to change the default combinations like admin/admin to more complex ones.
It is also important to check if your camera supports the mode static IPMost modern models from brands like Hikvision, Dahua or Reolink While some devices have this feature, budget Chinese no-name gadgets may have a limited interface. Checking the specifications before starting work will save you time.
Finding the camera's current IP address
Before changing any settings, you need to find the device on the network. The easiest way is to use the manufacturer's official software, which often has a network scanning feature. For example, the utility SADP Tool for Hikvision equipment or ConfigTool For Dahua, all connected devices are instantly displayed, even if their address does not match the router's subnet.
If you don't have proprietary software, you can use universal port scanners. Programs like Advanced IP Scanner or mobile applications Fing Allows you to see a list of all active devices. Look for the camera's brand name or its MAC address in the list of detected clients.
An alternative method is to log into the router's web interface. In the section State or Client list All connected devices are displayed. Find the desired device by name or MAC address and copy its current IP address. You'll need this value to determine which subnet you're on.
Sometimes the camera may have a default address, for example, 192.168.1.64, which does not match your router's subnet (for example, 192.168.0.x). In this case, the computer will not see the camera directly until you change the IP address of the computer's network card to the camera's range or use special tools to change the address.
What to do if the camera is not found?
If the scanners are silent, check the indicators on the camera body. A blinking network LED usually indicates a physical connection. Try temporarily disabling your firewall or antivirus software on your computer, as they may be blocking search queries on the local network.
Changing IP via the router's web interface
The most reliable way to assign an address to a camera is to set up DHCP Reservation on the router itself. This ensures the router will always assign the same address to the camera, even if it reboots. This is more efficient than changing settings within the camera itself, as it eliminates the risk of human error when entering data.
To begin, log into your router's control panel by entering its address in your browser (usually 192.168.0.1 or 192.168.1.1). Find the section that may be called LAN, DHCP Server or Address Reservation. Interfaces from different manufacturers (TP-Link, Asus, Keenetic, MikroTik) differ, but the logic is the same everywhere.
You'll need to create a new entry, specifying the camera's MAC address and the desired IP address. Make sure the address you select is in the same subnet as your router but not in the dynamic IP range to avoid conflicts. For example, if your router assigns IP addresses from 100 to 200, assign the camera address 50 or 250.
| Parameter | Description | Example of meaning |
|---|---|---|
| MAC address | Physical address of the device | 00:1A:2B:3C:4D:5E |
| IP address | Fixed network address | 192.168.1.150 |
| Subnet mask | Determines the size of the network | 255.255.255.0 |
| Gateway | Your router's address | 192.168.1.1 |
After saving the settings, you need to reboot the camera. It will request a new address from the router and receive the one you reserved. You can check the result using the same client list or by attempting to access the camera's web interface using the new address.
☑️ Checking your router settings
Manual IP configuration inside the camera
If your router doesn't support address reservation or you want to configure the camera independently of the DHCP server, you'll have to change the settings directly on the device. To do this, enter the camera's current IP address in the browser's address bar. You'll be asked to enter your username and password (the default is often admin/12345, but it's best to change them).
Find the section in the menu Network (Network) or TCP/IPHere you need to switch the address acquisition mode from DHCP (automatically) on Static (manually). After this, the fields for entering the address, mask, gateway, and DNS will become active.
Please enter the data carefully: IP address must be unique within your network, Mask usually 255.255.255.0, A Gateway — this is the address of your router. You can specify the same DNS servers as your router, or use public ones, such as those from Google (8.8.8.8).
⚠️ Important: When changing the camera's IP address to a static one, make sure you haven't assigned the same address to another device. Duplicate addresses will cause both devices to lose network connectivity.
After applying the settings, the camera will reboot, and you'll lose connection to it because it's now at a new address. To access the settings again, you'll need to enter the new IP address in your browser. If you lose access, use the network scanner described in the previous section to locate the device.
Using specialized software for configuration
For mass address changes or working with cameras whose IP address is unknown, it's more convenient to use specialized software. Manufacturers offer free utilities that operate below the standard network protocols, allowing you to "see" a camera even on a different subnet.
For example, the program ONVIF Device Manager — a universal tool for any camera that supports the ONVIF standard. It not only displays the device but also lets you change its IP address, mask, and gateway in a couple of clicks. This is especially useful if the camera's web interface is glitchy or won't open.
In such programs, the process looks like this: you select a camera in the list, go to the tab Network and change the settings. You'll often be asked to enter the camera's login and password to confirm the operation. After changing the address, the program will prompt you to update the device list or reconnect.
The advantage of this method is that you don't need to temporarily change your computer's IP address. The software will automatically configure the necessary temporary connections. However, for the utility to work, the computer and camera must be physically connected to the same switch or router.
Resolving access and conflict issues
Even with the correct settings, problems can still occur. A common error is an incorrectly specified subnet mask. If the camera is set to 255.255.0.0, and on the router 255.255.255.0, devices may not "see" each other, even though their addresses are technically in the same range. Always check these values.
Another issue is blocking by antivirus software or Windows Firewall. When connecting for the first time, the new camera may be seen as a device on a public network, and access to its ports will be blocked. Try temporarily switching the network profile to "Private" or "Home."
If the camera stops responding after changing its IP address, try resetting it to factory settings. Most models have a reset button on the camera body. Reset, which must be held down for 10-15 seconds while the power is on. This will reset the address to the factory value specified in the instructions.
It's also worth checking whether the WiFi client isolation (AP Isolation) feature is enabled on your router. If it's enabled, devices on the wireless network can't communicate with each other, and you won't be able to configure the camera over the air until you disable it.
What to do if the camera is visible but won't open?
Try switching browsers or using incognito mode. Older cameras often don't work correctly with modern browsers due to outdated security protocols. Try Internet Explorer (compatibility mode) or a specialized plugin from the manufacturer.
Is it possible to change the IP remotely if the camera is in another city?
Only if you already have access to its interface or it's connected to a cloud service with this feature. Changing the remote camera's IP locally without first setting up a tunnel (VPN) or port forwarding is impossible, as you're on a different network.
Does changing IP affect cloud recording?
Usually, no. Cameras with cloud services (P2P) are linked via a unique ID or QR code, not IP. However, if you're recording to an FTP or NAS with a local path, the links may become corrupted and will need to be updated in the camera settings.
What IP range is best for cameras?
It's best to use the outermost ranges, which DHCP doesn't distribute. For example, if your router distributes IP addresses from 100 to 200, assign your cameras addresses from 2-50 or 201-250. This will ensure there are no conflicts with your guests' new devices.
Do I need to change the access port when changing my IP?
No, the port (usually 80 for HTTP or 554 for RTSP) remains the same unless you change it. However, if you access it from outside (using port forwarding), you'll need to reconfigure the routing rules in your router for the camera's new IP address.
