Wyze Cam: Fixing Missing SD Card History - Smart Home | digitalhomefaults.org

Technical Background:

The Wyze Cam records video to a microSD card in a FAT32 or exFAT format. The camera's firmware controls this process and indexes the recordings for playback through the Wyze app. The app communicates with the camera via Wi-Fi (2.4GHz) using a proprietary protocol. Signal strength (RSSI) and network latency significantly impact the reliability of accessing the stored video. Power fluctuations, especially during Canadian winters, can corrupt the SD card's filesystem.

Symptoms:

No historical footage is visible in the Wyze app despite an SD card being installed. The camera's LED may show a solid blue light indicating normal operation, but attempting to view past recordings results in an empty timeline or an error message like 'No video at the selected time'. App logs may indicate SD card read/write errors.

Possible Causes:

Corrupted SD card filesystem due to power loss or improper ejection.
SD card incompatibility (e.g., using a card not rated for continuous video recording).
Weak Wi-Fi signal (low RSSI) preventing reliable communication between the app and the camera.
Firmware bug causing indexing issues or failing to write to the SD card.
Incorrect date and time settings on the camera preventing correct video indexing.
Mechanical failure of the SD card itself, especially after repeated read/write cycles in cold temperatures.

Solution:

1

Verify SD card compatibility: Use a high-endurance microSD card (Class 10 or UHS-I) specifically designed for continuous video recording (e.g., SanDisk High Endurance, Samsung PRO Endurance). Capacity: 32GB or less is generally more reliable.
2

Format the SD card: In the Wyze app, navigate to the camera settings, then 'Advanced Settings,' and select 'Format SD Card.' Choose FAT32 if given the option. Backup data if possible.
3

Check Wi-Fi signal strength: Use a Wi-Fi analyzer app on your smartphone to measure the RSSI near the camera. Aim for a signal strength of -60 dBm or better. Consider relocating the camera closer to the Wi-Fi router or adding a Wi-Fi extender (avoiding interference on 2.4 GHz band).
4

Ensure the camera's firmware is up to date: Check for updates in the Wyze app and install the latest version. Firmware updates often include bug fixes and performance improvements related to SD card recording.
5

Verify date and time settings: Incorrect date and time settings can cause indexing issues. Ensure the camera's date and time are synchronized with your local time zone in the Wyze app settings.
6

Power cycle the camera: Unplug the camera from the power source for at least 30 seconds, then plug it back in. This can resolve temporary glitches and refresh the camera's connection to the Wi-Fi network.
7

Test with a different SD card: If possible, try using a different SD card to rule out a faulty SD card as the cause. Note the SD card model and batch number for warranty claims. Ensure the replacement card is fully initialized by formatting it within the Wyze app.

Safety Warning:

Ensure the camera is disconnected from the power source before removing or inserting the SD card. Avoid using excessive force when inserting or removing the SD card to prevent damage to the card slot. Handle lithium batteries with care; improper handling can lead to fire. Dispose of old lithium batteries properly at designated recycling centers. Do not attempt to repair the camera yourself; refer to the manufacturer's warranty for repair options.

Prevention:

- Regularly format the SD card (every 3-6 months) to prevent filesystem corruption. - Monitor the SD card's health using the Wyze app (if available) or third-party SD card diagnostic tools. - Replace the SD card every 1-2 years, especially if used in harsh environmental conditions (extreme cold, high humidity). - Schedule regular firmware updates through the Wyze app to benefit from bug fixes and performance improvements. - Consider a surge protector for the camera's power supply to prevent damage from voltage spikes, common during Canadian storms.

Expert Tip:

If the problem persists, try a factory reset of the camera by holding down the setup button for 10 seconds until the LED flashes yellow. Then, re-pair the camera with your Wyze account. This can resolve persistent software glitches but will require reconfiguring all camera settings.

Frequently Asked Questions

•How do I safely remove the SD card from my Wyze Cam?

Power down the camera first. Gently push the SD card inward to release the spring mechanism, then carefully pull it out. Avoid using sharp objects.

•What type of SD card is best for Wyze Cams in cold Canadian winters?

A high-endurance microSD card with a wide operating temperature range (-25°C to 85°C or better) is recommended. SanDisk High Endurance or Samsung PRO Endurance are good options.

•How often should I format the SD card in my Wyze Cam?

Formatting the SD card every 3-6 months can help prevent filesystem corruption and maintain optimal performance, especially with frequent recording cycles.
