To complete Eufy S330 setup, download the Eufy Security app and sign in or create an account. Connect HomeBase 3 to your router using an Ethernet cable and add it through the app. Select Add Device and choose eufyCam S330. Press the camera’s SYNC button for two seconds and follow the on-screen instructions. Test the camera before mounting it securely.
Properly installing your security camera is crucial to guarantee the safety of your home, observe the surroundings, and receive timely notifications about irregular activities in your absence. In particular, the Eufy S330 setup process involves preparing the equipment, installing the application, pairing the camera, adjusting the settings, and testing the tool. Although this brand provides multiple products with similar labels, their setup procedures may differ. For instance, the eufyCam S330 is suitable for use with the HomeBase, while the Eufy 4G LTE Cam S330 has a built-in cellular processor. Moreover, the E330 model differs from the eufyCam S330 as it is designed for video doorbells. This article provides the major steps for setting up your Eufy S330, resetting or restarting the device, connecting it to Wi-Fi, and answering frequently asked questions.
Before installing the device, it is essential to assemble all the tools and equipment needed for the process. It is also critical to ensure that the network meets the requirements of the particular camera.
The eufyCam S330 and eufy HomeBase utilize the 2.4 GHz band to establish a connection between the camera and the HomeBase. In contrast, the Eufy 4G LTE cam S330 setup has an alternative set of procedures.
Eufy E330 installation starts by connecting your camera to a compatible power source and network. Open the Eufy Security app. Follow the on‑screen instructions to set up the Eufy E330. Finish pairing the Eufy E330. Check the live view. Then place the Eufy E330 camera where it can keep your home safe.
Correct positioning is essential to secure clear footage and continuous monitoring. Finish all of the following steps before permanently mounting your camera.
To complete your Eufy S330 camera setup, follow these simple steps:
Note: The 4G LTE Cam S330 has a different setup procedure.

The process of restarting may resolve a number of issues, including connectivity problems, a live view freezing, or notification delays. However, the action should be taken in accordance with the camera model.
The Eufy S330 is a camera designation and not the name of a specific smart lock. Please note that if you are installing an Eufy smart lock in conjunction with your S330 security camera, you will have to set up the lock as a separate device.
Key point: Do not follow a generic S330 camera procedure to install a smart lock. Also, if you intended to install the mounting bracket of your S330 camera, you should use the positioning template and mounting hardware provided.
The connection procedure will differ depending on the device you choose to install: the eufyCam S330 setup or the 4G LTE Cam S330 setup.
Eufy notes that it may be possible to switch to Wi-Fi from HomeBase on compatible firmware.
Note: Please note that binding through Wi-Fi is only possible if your device and connection options are compatible.
To turn off Eufy S330, open the Eufy Security app on your phone and select your camera from the list of devices. Once you have accessed the camera interface, click on the settings tab and scroll down the page to locate the control panel. Here, you should be able to access the available tools for disabling monitoring, recording, or motion detection. If you wish to turn off your camera, you should consult the user manual for your device and look for a procedure titled “how to turn off the camera.” Note that deactivating the camera’s notifications does not turn it off, and we do not recommend performing a factory reset to power down the device.
A factory reset may help if pairing attempts fail or if you need to reconfigure the camera. It may undo existing settings, so try this when restarting, checking the network, and more.

For the 4G LTE Cam S330, Eufy’s troubleshooting guidelines describe what SYNC-button actions are required to resolve specific SYNC-related setup failures. These button actions should not be used for the eufyCam S330 model.
Note: A factory reset does not always delete the cloud account ownership or free up a device from an existing account. If the camera is still bound to another account, contact Eufy support to learn what the proper procedure is.
A Eufy S330 firmware update can resolve multiple issues, enhance the performance of the device, and ensure the best functioning of the camera. It is essential to update the firmware via the official app or the manufacturer’s website to guarantee the best results.
Users can follow the steps below to update their Eufy security camera’s firmware:
It is noteworthy that the menu options in the Eufy application can be different based on the camera model and app version. In case of a failed update, it is advisable to check the internet connection, battery level, and other technical specifications and refer to the official guidelines provided by the manufacturer.
The names S330 and E330 are different, which means that these are distinct Eufy models and thus have nothing to do with each other.
