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.265 and H.264 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. You can subscribe to Reolink’s firmware updates to stay informed when new firmware versions add support for this feature.

Understanding Encoding Formats: H.265 VS H.264

H.264 and H.265 are two widely used video compression standards. 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.

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.

Setting Up Encoding Format

  • Using the Reolink App

    1. Go to Camera Settings:

    Open the Reolink App, select the camera you want to configure, and tap on the gear icon to access the Settings menu.

    2. Access Stream Settings:
    Choose the "Display" section and tap on "Stream."

    4. Select Encoding Format:
    Tap on "Encoding format" and then choose either H.264 or H.265 based on your requirements. H.265 encoder is recommended for higher efficiency, especially if your network bandwidth is limited.
