Hi! I see you're having trouble with playback on one camera in the DMSS app after clearing the phone cache. I’d like to help you get this sorted out. To start, could you tell me:

- Is the issue happening only on that one specific camera or others as well?
- Are you seeing any error messages or does the playback just fail to load?
- Have you tried restarting the app or your phone since clearing the cache?

Meanwhile, here are some steps we can try based on common fixes for playback problems in DMSS:

1. Restart the App and Device: Sometimes, after clearing cache, the app or device may need a fresh reboot to fully reset its connection to the cameras. Please close the DMSS app completely (make sure it's not running in the background) and then reboot your phone.

2. Check Network Connection: Playback relies on stable network access. Ensure your phone is connected to a reliable Wi-Fi or mobile data network.

3. Verify Camera is Online: Confirm the camera itself is online and recording. You can try viewing the live stream for that camera to verify.

4. Re-login or Refresh Device List: Log out of the DMSS app and log back in. Refresh your camera list or try removing and re-adding the camera/device in the app.

5. Playback Filter Settings: In some cases, playback might get stuck if video type filters are applied. Check if there is a filter or calendar time selection that’s limiting playback.

6. Update the App and Device Firmware: Ensure your DMSS app and the camera firmware/NVR software are up to date. Sometimes playback issues are resolved with updates.

If playback still does not work after these steps, we can explore advanced fixes like re-adding the device, checking account permissions, or even reverting to a previous app version if it’s a new issue after an update1 3.

Let me know what you’ve already tried or what you see on your end, and we’ll go from there!

cleared cache also rebooted

Thanks for letting me know you’ve already cleared the cache and rebooted your device. That helps narrow things down.

Since playback is still not working on that one camera, let’s try the next steps to resolve it:

1. Check for App and Firmware Updates: Make sure your DMSS app on your phone and your camera’s firmware/NVR software are both updated to the latest versions. Update if needed, since outdated software can cause playback issues.

2. Reinstall the DMSS App: Sometimes clearing cache isn’t enough if certain app files are corrupted. Please uninstall the DMSS app completely from your phone, then download and reinstall it fresh from your app store.

3. Verify Camera Status and Network: Confirm the camera is online and the network connection is stable. Try viewing the live stream for that camera to see if it works properly.

4. Remove and Re-add the Camera: If available, remove the problematic camera/device from the app, then add it back again. This can refresh the connection and fix account/device sync issues.

5. Check Playback Filters and Time Selection: When accessing playback, double-check there is no filter like event type or date/time that’s restrictive, which might prevent loading videos.

6. Permissions and Account Check: Make sure your account has the right permissions for playback on that camera, especially if it’s shared or part of a multi-user setup.

If after trying these the playback still doesn’t work, we may need to try more advanced troubleshooting or check if there are known server side or app bugs affecting playback on your device model and OS version.

Would you like me to guide you through reinstalling the app or removing and adding the camera? Also, please let me know if you see any error messages when playback fails. That info can help pinpoint the issue further1 3.

can't find code

Thanks for the update. When you say "can't find code," are you referring to a verification code for signing into the DMSS app, or are you looking for the QR code or device code to add the camera to the app? Just want to make sure I understand exactly what code you’re having trouble locating.

If it’s a verification code (like one sent via SMS or email for login or signup), here are some quick tips:
1. Check your phone’s SMS inbox carefully, including spam or junk folders.
2. Make sure SMS blocking or filtering isn’t enabled on your device.
3. Restart your phone’s network connection or switch between Wi-Fi and mobile data.
4. If code delivery still fails, try uninstalling and reinstalling the DMSS app and then requesting the code again3 1.

If you’re trying to find the QR code associated with your camera or device to add it manually, it’s often found:
- On a label attached to the physical camera or NVR device itself
- Inside the device’s local web interface under device info
- Sometimes in the setup or device info section of the existing DMSS app if it’s already added2 4.

Could you clarify which code you’re referring to? That way, I can provide steps tailored to your exact need.

can't find QR code

Thanks for clarifying that you’re having trouble finding the QR code for your camera in the DMSS app. I can guide you through where to look and how to add your device without the QR code if needed.

Here are some ways to find or work around the missing QR code:

1. Check the Physical Camera or NVR Device: Most cameras or NVRs have a label on the back or bottom with a QR code and serial number. This is usually what you scan with DMSS to add the device.

2. Use the Serial Number Instead: If you can’t find the QR code physically, you can manually enter the device’s serial number (SN) into the DMSS app. In the app, tap the "+" icon, choose "Add Device," then select "SN/Scan" and type the serial number instead of scanning.

3. Access the Device’s Local Web Interface: If you have access to the camera or NVR’s web portal via its IP address on your network, you may find the QR code or the serial number in the device information section.

4. Inside DMSS App (For Already Added Devices): If the device is already in your DMSS app but you need the QR code (e.g., to share or link to another app), look under device details or settings for “Device QR code” or “Share device” which may generate a QR code for scanning.

5. Rebind or Request New QR Code: Some newer firmware versions allow “self-unbinding” if the device is linked to another account. If you get an error adding the device, you might request the device to unbind itself and generate a fresh QR code7 3 9.

If you tell me the exact model of your camera or NVR and whether it’s already added to any DMSS account, I can help you with more precise instructions.

Would you like guidance on manually adding the camera via serial number or help checking device info through the web interface first?
