How to Fix Hikvision Wifi Disconnection Issues
A Hikvision security system provides robust surveillance, but its remote access capabilities are only as good as its network connection. If your Hikvision NVR or IP cameras are constantly disconnecting from your wifi network, you lose the ability to view live footage, receive alerts, and check recordings remotely via the Hik-Connect app. This can be a major security vulnerability.
This guide is written for Hikvision users in the UK to help you diagnose and resolve the common causes of wifi disconnections, leading to a more stable and reliable security setup.
### Understanding the Symptoms of a Network Problem
Wifi disconnection issues can appear in several ways:
- "Device is Offline" in Hik-Connect: The most common symptom, where the app simply cannot reach your device.
- Intermittent Live View: The video stream works for a short period, then freezes or drops out, showing a "network unstable" or similar error.
- Failed Playback: You are unable to view recorded footage remotely, as the app cannot establish a stable connection to the NVR's hard drive.
- Error Codes: You might see specific network-related error codes in the app or on the NVR's local interface (e.g., Error Code 245418).
- Camera Status on NVR: If you have an NVR, the connected camera status might frequently switch between online and offline.
A Strong Recommendation: Use a Wired Connection If Possible
Before we dive into wifi troubleshooting, it's important to state that for any serious CCTV installation, a wired Ethernet connection is always superior to wifi. It is faster, more secure, and vastly more stable. If it is at all feasible to run an Ethernet cable from your NVR or camera directly to your router, we strongly advise you to do so. This will solve the vast majority of disconnection problems.
If a wired connection is not an option, the following steps will help you create the most stable wifi connection possible.
Troubleshooting Hikvision Wifi Disconnections
### 1. Check Wifi Signal Strength
This is the number one cause of wifi dropouts. A security camera needs a consistently strong signal.
- Location is Key: The further your camera or NVR is from your wifi router, and the more walls (especially brick or concrete) are in between, the weaker the signal will be.
- Perform a Test: Use your smartphone. Stand exactly where the problematic Hikvision device is located. Check the wifi bars on your phone. If you have anything less than full or nearly full bars, the signal is likely too weak for a stable video stream.
- Solutions:
- Move your wifi router to a more central location in your property.
- Install a dedicated wifi access point or mesh wifi node closer to the Hikvision device. A simple "repeater" or "extender" can sometimes help but is not as effective.
### 2. Assign a Static IP Address
By default, your router assigns IP addresses dynamically (using DHCP). Sometimes, when an address lease expires, the router might assign a new one, causing the NVR or camera to lose its connection. Setting a static (fixed) IP address prevents this.
- Use Hikvision's SADP (Search Active Devices Protocol) tool on a computer on the same network to find your device's current IP address.
- Log in to your device by typing this IP address into a web browser.
- Navigate to Configuration > Network > Basic Settings > TCP/IP.
- Untick "Enable DHCP".
- Manually enter an IP address that is outside the range your router uses for DHCP. For example, if your router assigns addresses from 192.168.1.100 to 192.168.1.200, you could set your camera's IP to 192.168.1.50.
- Ensure the Subnet Mask (usually 255.255.255.0) and Default Gateway (your router's IP address, e.g., 192.168.1.1) are correct.
- Save the settings.
### 3. Change Wifi Channel
Your wifi network operates on a specific channel. If your neighbours' networks are on the same or an overlapping channel, it can cause interference.
- Log in to your router's administration panel.
- Find the wifi settings.
- The 2.4GHz band (which Hikvision devices use) has channels 1-13. The best channels to use are 1, 6, and 11 as they do not overlap.
- Try changing your router's channel to one of these to see if it improves stability.
### 4. Update Device Firmware
Firmware updates often contain fixes for network-related bugs.
- Visit the official Hikvision UK portal.
- Search for your specific device model number.
- Download the latest firmware file.
- Log in to your device via a web browser and use the Maintenance or System Configuration section to upload and apply the firmware update. Follow the instructions carefully as a failed firmware update can cause serious problems.
By systematically addressing signal strength, IP addressing, and potential interference, you can create a much more reliable wifi connection for your Hikvision system.
