How do I reset the password if I forget it?

On the login screen, click Forgot Password. A QR code will appear. Scan it with your smartphone and follow the instructions on the screen. You will need the device serial number and your registered email to reset.

What type of hard drive can I install?

The device supports one 3.5-inch SATA hard drive up to 10TB. We recommend using surveillance-grade HDDs for continuous recording. The HDD must be formatted to the device's proprietary file system.

How do I install a hard drive?

1. Power off the device and disconnect all cables. 2. Remove the screws on the top cover and slide it off. 3. Align the HDD screw holes with the bracket holes and fasten the screws. 4. Connect the SATA data and power cables from the HDD to the mainboard. 5. Replace the cover and fasten the screws. 6. Power on and initialize the HDD in the system menu.

Can I use both HDMI and VGA at the same time?

Yes, HDMI and VGA outputs work simultaneously and display the same video source. However, if you set HDMI to 4K resolution, the VGA output will automatically stop. The TV output (CVBS) also works simultaneously.

How do I set up motion detection recording?

Go to Main Menu > Alarm > Video Detection. Select a channel, enable motion detection, and adjust the sensitivity and area. Then go to Storage > Record, select the channel, and set the record mode to Motion Detection. You can also configure alarm actions like email notifications.

What AI features are available on this model?

This model supports face detection (age, gender, glasses, mask), face recognition (compare with a database), IVS (tripwire and intrusion detection), and human/vehicle detection. These can trigger alarms and record events.

How do I configure IVS (tripwire/intrusion) rules?

Go to Main Menu > AI > IVS Mode. Select a channel, enable IVS, and click Add Rule. Choose between tripwire or intrusion. Draw a line or area on the preview image. Set the direction, sensitivity, and action (e.g., alarm out, recording). Apply the changes.

What is the maximum number of IP cameras I can add?

The device can manage up to 8 channels in total. These can be analog, HD coaxial, or IP cameras. The exact number depends on the model; for XVR5108H-4KL-I2, all 8 channels support analog/HD, and you can also add IP cameras via the PoE switch or network.

How do I perform a factory reset?

Go to Main Menu > System > Default Settings. Choose Restore Default Settings to reset all parameters except network settings, or Factory Default to reset everything. Alternatively, you can press and hold the RESET button on the rear panel for 10 seconds while powered on.

Can I access the DVR remotely from my phone?

Yes, download the DMSS (or Smart PSS) app from the app store. Add the device by scanning its QR code or entering the serial number. Ensure the DVR is connected to the internet and the network settings (e.g., P2P or DDNS) are configured correctly in Main Menu > Network.
