Adjusting Camera Settings for Maximum Resolution, FPS, and Bitrate
Most Amcrest products are H.265 compatible. H.265 provides a more advanced technology than H.264
and allows the camera to reduce file sizes which in turn helps to reduce required bandwidth without
sacrificing frames per second (FPS) or resolution. However, for maximum compatibility when accessing
your device in a web browser, or other third-party applications, our H.265 compatible products will come
factory default to H.264. For optimal performance, the device's settings can be upgraded to H.265
compression if needed.
Please note, for higher performance as well when using H.265 compression it is recommended to adjust
bitrate. The bitrate is the number of bits that are processed per unit time by the system and helps the
system to create a tradeoff between bandwidth and image quality.
How to Adjust to H.265 Compression
If the auto switch for H.265 compression was not selected in the camera registration process, the setting
can be adjusted manually. On the Main Menu, under Management, click on Camera.
In the Camera menu, select Encode and click on the Compression drop down menu and select H.265.
Click Save to save your settings.
Adjusting Bitrate
Since H.265 compression uses roughly 30% less resources than H.264, the camera will typically come
defaulted to a preset bitrate when switching to H.265. For instance, when switching to H.265 on a 4K
camera, the bitrate may be defaulted to 8192 Kb/S, however, adjusting the bitrate to a lower value may
help to increase the overall efficiency of the camera while viewing playback or watching live view.
To adjust the bitrate, access the Encode menu and click on the Bit Rate (Kb/S) dropdown menu. A list of
preset bitrates will be displayed as well as a Customized selection which will allow you to set a customized
bitrate if needed.
