Because EZVIZ is a consumer brand under Hikvision, many EZVIZ cameras can interface with Hikvision desktop management tools. This method requires your camera to be connected to the same local network as your computer. Step 1: Download the Tools

Once the camera reboots successfully with the older firmware, you must take immediate steps to prevent the camera from automatically upgrading itself again.

This usually means the firmware file you downloaded does not match the hardware revision of your camera, or the camera's current software has an anti-rollback protection block. Try to find a slightly less outdated version of the firmware instead of jumping back multiple years at once.

: This is the most common complaint. RTSP is the feature that allows you to stream your camera's video feed to third-party software like Home Assistant, Blue Iris, or VLC Media Player. A user on the IP Cam Talk forum reported: "I upgraded my EZVIZ WiFi Video Doorbell (CS-DB1) from V5.2.4 build 220530 to V5.2.4 build 230404 after noticing an available update... The camera works fine in the EZVIZ app, but I can no longer connect to it via RTSP." For users who have built a smart home ecosystem around these streams, losing RTSP can make an otherwise functional camera obsolete. This issue is not isolated; Ezviz has been known to disable RTSP on many of its cameras with its 2023 firmware updates. Some users have found that downgrading can restore this functionality.

Always use a stable power source and, if possible, a wired LAN connection during the process.

EZVIZ is a popular brand of smart home security cameras and devices that offer advanced features like motion detection, night vision, and cloud storage. However, sometimes users may want to downgrade their EZVIZ device's firmware to a previous version, perhaps due to compatibility issues or to resolve bugs introduced in the latest update. In this post, we'll walk you through the process of downgrading your EZVIZ device's firmware.

Downgrading EZVIZ firmware is a high-stakes, unsupported procedure primarily used to restore lost functionality, fix bugs, or regain compatibility. While documented guides exist for models like the CS-DB1, C6N, and C8PF, the process can permanently "brick" your device.
