Frequently Asked Questions - DS-C12L-0204H Hikvision

How do I activate the DS-C12L-0204H for the first time?

You can activate the device using the Video Wall Client software or SADP tool. Ensure your computer is on the same network segment. On the client, go to Device Management, select the inactive device, and click Activate. Set a strong password (min 8 characters with at least three of: uppercase, lowercase, numbers, special characters).

What should I do if I forget the device password?

Use the password reset feature on the client. Go to Device Management, select the device, click Reset Password, export a GUID file, and send it to Hikvision technical support to get a key file. Import the key file to clear the password, then set a new one.

Can I cascade multiple DS-C12L units for a larger video wall?

Yes, up to 4 devices can be cascaded to support up to 16 screens. Connect loop cables (HDMI) and sync cables (network) between devices in a daisy chain. Then configure the cascading topology in the Video Wall Client under Device Topology.

How do I switch between the two HDMI input signals?

You can switch inputs three ways: 1) Press the SWITCH button on the front panel. 2) On the client, drag a different signal source to the video wall window. 3) Use an external keyboard connected via RS-232/485.

What is the maximum resolution supported for input and output?

Both input and output support up to 4K@60 Hz (4092×2160). However, when using 4K@60 Hz on HDMI OUT 1, outputs 2, 3, and 4 are disabled.

How can I customize the input signal resolution?

On the client, go to Remote Configuration > Video Display > Signal Source Resolution. Enable resolution customization, select the signal source, and set the refresh frequency and resolution (width multiple of 4, height multiple of 2, up to 4092×2160).

Is it possible to use PoE to power the device?

Yes, the device supports PoE (IEEE 802.3at) via the LAN port. Alternatively, you can use the included DC 12V power adapter. Only one power source should be connected at a time.

How do I configure audio output?

Audio is output via the LINE OUT interface (3.5mm jack) on the rear panel. By default, audio is enabled. To disable it, right-click the video wall window on the client and select Disable Audio.

Can I set a background picture on the video wall?

Yes. On the Video Wall interface, click Background Picture. Drag the default system picture to the window. You can show or hide it using the lock icon. Custom images are not supported.

How do I update the firmware of the device?

On the client, go to Remote Configuration > System > System Maintenance. Under Remote Upgrade, select and import the upgrade file, then click Upgrade. Ensure the device is stable and do not power off during the process.

• Ensure that the air vents on the sides of the devices are not blocked.

2.1.2 Wall Mount

If you want to mount your device on the wall, you can choose wall-mount installation.

Before You Start

• You have determined and marked the mounting locations on the wall. The recommended distance between the two mounting holes is 186 mm.
• You have left space for wiring and ventilation.

Steps

1. Drill two mounting screws into the marked locations on the wall.

Note

M4 pan head screws are recommended for mounting, and the head diameter should be greater than 5 mm but smaller than 9 mm.

1. Align the mounting holes on the bottom of your device and mount your device onto the screws.

Figure 2-3 Mounting Hole Position

1. Repeat the above steps to complete the installation of the rest of your devices.

2.1.3 Magnetic Mount

If you want to mount your device on metal surfaces such as a video wall bracket or the rear of an LCD screen, you can choose magnetic-mount installation.

Before You Start

• You have determined the mounting locations.
• You have left space for wiring and ventilation.
• You have prepared four magnetic feet and four M3 countersink screws.

Steps

1. Use the four M3 countersink screws to mount the magnetic feet on the bottom of your device.

Figure 2-4 Mount Magnetic Feet

1. Stick your device onto the flat metal surface, such as the video wall bracket or the rear of the LCD screen.
2. Repeat the above steps to complete the installation of the rest of your devices.

2. Draw the loop lines according to the physical cable connections.

1) Move your mouse on the loop out interface of the master device, and left-click and hold your mouse.
2) When the interface is circled in red and a red point appears in the middle, hold and move the mouse to draw a connection line to the loop in interface of one of the slave devices.
3) Repeat the above steps to complete the rest of devices.

Note

• The cascading topology relationship must be consistent with the actual device relationship.
• You can view device information such as the IP address and serial number by double clicking the device.
• If you want to change the cascading relationship, press the Delete key to delete the lines and draw them again.

4. Click Save.

2. Set Output Type to LCD or LED.

3. If your video wall is an LCD type, set the output type to LCD.

4. If your video wall is a LED type, set the output type to LED.

5. If your video wall is an LCD type, configure the resolution. You are recommended to configure a resolution the same as that of the video wall to achieve the optimal image effect.

Figure 3-2 Configure LCD Output Parameters

If multiple devices are cascaded, the LCD resolutions of all the devices must be the same.

1. If your video wall is a LED type, configure the width and height in the text fields. A LED display is dot-matrix, and the width and height are the dots.

Figure 3-3 Configure LED Output Parameters

Note

• To customize the LED resolution, select a standard LCD resolution first and then customize the resolution within the standard pixels. For example, if you have selected the standard 1080P LCD resolution, the customized LED resolution cannot exceed 1920 × 1080 .
• To change customized resolutions, change the resolutions in the same row or column simultaneously. Otherwise, an error may occur.

• If multiple devices are cascaded, ensure that your video wall has the same height in the same row and the same width in the same column.

• Optional: Configure Background as needed.

• Optional: Check Batch Configuration to copy the configuration to other decoding outputs.
• Click OK.

3.1.3 Link Decoding Output to the Video Wall

You must link decoding outputs of your devices to the video wall so that signals can be displayed on the video wall. All decoding outputs of your devices are displayed on the video wall configuration interface.
