How to Fix a Reolink Camera That Keeps Disconnecting
A security camera that frequently goes offline is not just an annoyance; it's a reliability issue that undermines its very purpose. If your Reolink camera, whether it's a Wi-Fi model like the Argus or a wired PoE camera, is constantly disconnecting, this comprehensive guide will help you diagnose and solve the problem.
We will explore the three main pillars of a stable connection: a reliable power supply, a strong network link (Wi-Fi or wired), and up-to-date software.
Step 1: Verify the Power Supply
A consistent power source is non-negotiable. An unstable power supply can cause the camera to restart or shut down, which looks like a network disconnection.
- For Battery-Powered Cameras (e.g., Reolink Argus): Check the battery level in the Reolink app. If the battery is critically low, the camera may shut down. If you are using the Reolink Solar Panel, ensure it is positioned to receive several hours of direct sunlight per day and that the cable is securely connected.
- For DC-Powered Cameras: Check that the power adapter is firmly plugged into both the camera and the wall socket. Inspect the entire length of the power cable for any signs of damage, pinching, or fraying. If possible, try using a different, compatible power adapter to rule out a fault with the original one.
- For PoE (Power over Ethernet) Cameras: The issue could be with the Ethernet cable or the power source (NVR or PoE switch). Try a different Ethernet port on your NVR or switch. Inspect the cable for damage and, if you have a spare, test the camera with a different cable. A faulty cable is a very common culprit for intermittent PoE connections.
Step 2: Troubleshoot the Network Connection
This is the most common area for disconnection issues, especially for Wi-Fi cameras.
For Wi-Fi Cameras
- Check Wi-Fi Signal Strength: In the Reolink app, navigate to 'Device Settings' > 'Network' to check the signal strength. If it's only one or two bars, the signal is too weak for a stable connection.
- Reduce Distance and Interference: The camera may be too far from your router. Physical barriers like brick walls, metal sheeting, and even dense foliage can block the signal. Also, be aware of interference from other 2.4GHz devices like baby monitors, cordless phones, and microwave ovens.
- Optimise Your Wi-Fi Network:
- Use the 2.4GHz Band: While 5GHz is faster, 2.4GHz offers a longer range and better penetration through walls, making it more reliable for security cameras.
- Set a Fixed Channel: Use a Wi-Fi analyser app to find the least congested channel (1, 6, or 11) in your area and manually set your router to use it.
- Position Antennas: Ensure the camera's external antennas are positioned correctly (usually vertically) for optimal signal reception.
For Wired (PoE) Cameras
- Cable Integrity is Key: The single most common failure point for a wired camera is the Ethernet cable. Even a small kink or a damaged connector can cause the connection to drop intermittently. Test with a known good, high-quality Ethernet cable (Cat5e or Cat6).
- Check Port Status: Look at the Ethernet port on your NVR or switch. The link lights should be solid or blinking steadily. If they are off or blinking erratically, it indicates a problem with the port or the cable.
Step 3: Update Firmware
Manufacturers like Reolink regularly release firmware updates to fix bugs, improve performance, and enhance security. An outdated firmware version can sometimes cause connectivity issues.
- Open the Reolink App and go to 'Device Settings'.
- Tap 'Device Info' or 'System'.
- Look for an option to 'Check for Updates' or 'Upgrade'.
- If an update is available, follow the on-screen instructions to install it. Do not disconnect the camera's power during the update process.
By systematically checking the power supply, strengthening the network link, and ensuring your firmware is up to date, you can build a rock-solid, reliable connection for your Reolink security camera.
