<Update label="May 2023" description="">
  * **exploreHD 3.0 (400m)** - [Product Page](https://dwe.ai/ehd)
    * Fixed issue where when H.264 is used in lower resolution, artifacts would show up on video.
</Update>

<Update label="March 2022" description="">
  * **exploreHD 2.0 (400m)** - [Product Page](https://dwe.ai/ehd)
    * Thanks to dweOS (previously known as driverUI), the firmware loader no longer needs 2 separate firmware to switch between H.264 and MJPEG streaming.
    * Default H.264 firmware bitrate has been decreased from 15 Mbps to 10 Mbps for improved stability.
</Update>

<Update label="January 2022" description="">
  * **exploreHD 2.0 (400m)** - [Product Page](https://dwe.ai/ehd)
    * The firmware loader now has two options of firmware, MJPEG or H.264:
      * MJPEG will provide the highest quality but bandwidth can go as high as 60Mb/s per camera.
      * H.264 will limit to 10Mb/s and use intelligent compression to maximize quality for the given bandwidth.
</Update>

<Update label="November 2021" description="">
  * **exploreHD 1.0 (400m)** - [Product Page](https://dwe.ai/ehd)
    * The loader now disables the other firmware button while loading to minimize the chance of failure
