If you encounter difficulties when trying to initialize the SD card via the EZVIZ APP, below are some troubleshooting steps to resolve the issue for you:

1. Ensure both the firmware of your camera and EZVIZ APP are running on the latest version.

2. Ensure the SD card is class 10 or rated at UHS-1. The file format of the SD card should be FAT32 for capacities below 64GB and exFAT for capacities of 64GB and above. Click Here to view partial test results of SD card compatibility.

3. Power off your camera, remove and reinsert the SD card, power the camera on and then initialize the card again on the EZVIZ APP.

4. To further rule out the SD card issue, you may try to test with a different SD card or install the card in question on another EZVIZ device. 

5. Try to factory reset your camera by holding the Reset button. This will turn the device to the default factory settings and might help resolve minor issues.

1. Please check the status of the indicator light first:

- If it is solid blue or flashing blue slowly, please refresh the home page on the EZVIZ APP to check whether the camera becomes online or not.

- If the indicator light is flashing red slowly, you can try the following two methods:

1) Please reboot your router as it may be experiencing connectivity and range issues.

2) Unplug your camera, wait for 10-30 seconds, then plug it back in to see if this solves the offline problem.

2. If the camera is still offline, you can try to reconfigure it by following the steps below:

- Connect your smartphone to your 2.4GHz home Wi-Fi network if your camera supports 2.4GHz only.

- Open your EZVIZ APP, tap the three-dot icon to enter the Device Settings page and tap the Wi-Fi button.

- Reset the device by pressing the reset button for a few seconds.

- Wait for a while, make sure the indicator light turns to flash blue quickly and tap Next.

- Check that your WIFI and password are correct. Then tap Next to connect to device AP.

- Please wait for the device to be configured and your device should be back online. 

We understand that you may be experiencing difficulties connecting your device online via an Ethernet cable. To troubleshoot the issue, we recommend the following steps:

1. Verify the router and cable: Ensure that both the router and cable are in proper working order. You can try using a different cable or connecting the cable to a different port on the router to eliminate any potential issues.

2. Test the connection: After checking the cable and router, attempt to establish a connection again and see if the problem persists. If it does, proceed to the next step.

If the issue persists despite trying different cables and ports, we recommend reaching out to our EZVIZ support team for further assistance.

If you encounter a squealing sound when you are using the two-way talk feature, please kindly note that the squealing sound you hear is very likely a result of the audio feedback loop between the microphone of the camera and the speaker of your mobile phone, a normal acoustic phenomenon that occurs when a microphone picks up sound from a speaker while that speaker is playing sound from the microphone, thus creating a loop.

To avoid this, please ensure when you use two-way audio:

- there are no interfering objects around the camera such as metal objects, electrical appliances, electronic equipment, etc.

- there is no microphone or other radio equipment near the camera.

- your mobile phone is NOT too close to your EZVIZ device.

Otherwise, the audio feedback loop will create a high-pitched squealing sound.

It is estimated that for a 1080P EZVIZ security camera, a 16GB Micro SD card will provide approximately 28-32 days of recording under normal use, which is about 1 hour of motion event recordings a day. Recording time for 720p cameras will be longer. 

Here is the estimated number of required spaces for your reference. Please note that the actual space taken up may vary depending on the operating environment and other factors.

Please kindly note that the device is programmed to timeout every few minutes if you are streaming through our VTDU servers. You can simply tap on the "Continue" button to continue streaming. Besides, if your device supports the LAN Live View feature, you can avoid this by putting your camera and your phone or PC under the same LAN (connecting to the same network), and then going to the More page (click the profile photo on the left top corner) > Settings > LAN Live View (for mobile phone) or Devices on LAN (for PC Studio). There you could view the camera continuously.

However, even when you are on the same network, you should ensure that the computer you are using is connected to the router using a cable, or if you are using a mobile phone or tablet, please ensure that you have Upnp enabled on your router.

1. Make sure your camera is online and it has a stable and strong internet connection. Poor or intermittent connectivity can prevent recordings from being uploaded to the cloud and we do suggest an average upload speed of 2 Mbps or better.

2. Make sure that your camera is not in Super Power Saving mode/Sleep mode/Privacy mode if your camera supports one of these features.

3. Ensure that your CloudPlay plan is active and in use. You can check the status of the service by going to camera Settings>CloudPlay. When the status is "Service paused", please check if the Recording button on the CloudPlay page is enabled. In order to check this, you will need to tap the three-dot-like icon in the top right corner of the CloudPlay page> Recording Setting.

4. If all the above settings are normal, please perform a test from your side to check whether the camera can be triggered normally or not. You may enable the Alarm Notification feature in camera Settings>Alarm Notification, then wave your hands in front of the camera lens until you can receive an alarm notification.

5. If you cannot receive an alarm notification when you perform the test, please reset your camera by pressing and holding the Reset button for a few seconds and reconfiguring it. This may help to resolve any problems.
