Setting the correct encoding format on your Reolink security cameras is essential for achieving the best video quality while optimizing bandwidth efficiency. This guide explains the differences between H.264, H.265, and H.265+, and provides step-by-step instructions for configuring the encoding format on your Reolink devices.
Note: Currently, only some PoE and DC-powered WiFi camera models support this feature.
It is recommended to upgrade your camera to the latest firmware version and check whether this option appears in the settings. If the option is still unavailable, it means your current model does not support it yet.
To use H.265+ on NVR, your connected Reolink NVR should be updated to firmware v3.6.4 or later. Currently, only the app and the NVR monitor support configuring H.265+.
Understanding Encoding Formats: H.264, H.265 and H.265+
H.264, also known as Advanced Video Coding (AVC), is a well-established standard that offers good balance between video quality and file size.
H.265, also known as High Efficiency Video Coding (HEVC), provides significantly better compression efficiency compared to H.264, resulting in higher video quality at lower bitrates or reduced file sizes while maintaining the same quality. This makes H.265 ideal for high-definition video streams and environments where bandwidth is limited.
H.265+ is an enhancement to H.265 that takes compression efficiency even further. By leveraging scene analysis to dynamically reduce bitrates during static or low-motion periods, H.265+ can help reduce bitrate by about 50% to 60% compared to H.265 under typical conditions, with actual performance varying based on the scene.
Best Practices
- Bandwidth Considerations: If you have limited network bandwidth, consider using H.265 to reduce the amount of data transmitted without compromising video quality. However, if bandwidth is not a concern or if you require compatibility with a wider range of devices, H.264 might be more practical.
- Device Compatibility: H.264 codec is the most widely supported codec across devices and platforms. While H.265 codec is gaining support, it's essential to check that all devices and applications used to access the camera stream can decode H.265 before making the switch.
- H.265+ for maximum storage savings: If your camera model supports H.265+, consider enabling H.265+ for maximum storage and bandwidth efficiency — especially useful for 24/7 continuous recording setups.
Setting Up Encoding Format
-
Using the Reolink App
Step 1. Open the Reolink App, select the camera you want to configure, and tap on the gear icon to access the Settings menu.
Step 2. Choose the Display section and tap on Stream.
Step 3. Tap Clear to configure the Encoding Format as needed. H.265 encoder is recommended for higher efficiency, especially if your network bandwidth is limited.
Note: If your camera model supports H.265+, the Intelligent H.265+ option will appear after selecting H.265. You can enable it as needed.

Using the Reolink Client
Step 1. Open the Reolink Client, click on the camera you want to configure, and navigate to Camera Settings.
Step 2. Go to the Device tab, click Stream, then Clear settings, and select either H.264 or H.265 under Encoding Format. -
Using a Monitor Connected to Reolink NVR
👉 Applies to: All Reolink NVR (New UI)
Preparation: Connect a monitor to the Reolink NVR via an HDMI/VGA cable.
Step 1. Click Settings (it may appear at the top or bottom of the screen, depending on your NVR version)> Camera, choose the camera you want to configure and navigate to Stream Settings.
Step 2. On Main Stream, select either H.264 or H.265 under Encoding Format.Note: If your camera model supports it, the Intelligent H.265+ option will appear after selecting H.265. You can enable it as needed.
By understanding the differences between H.264, H.265, and H.265+, you can configure the most appropriate encoding format for your Reolink camera to enhance video quality and network efficiency.
