Troubleshooting

Is there any problem with the power cable for connecting this product to the power supply unit? (If the cable is too long or thin, this may increase the resistance and prevent the voltage from being properly supplied.)

Is the lens cap attached?

Is the port number to be used when the client computer accesses to the camera via HTTP correctly specified?
(If the port number is incorrect, the Built-in Viewer menus will be displayed, but videos will not appear, and a “Connection is failed” message will be displayed instead.)

Is connection established using a PoE Plus (compliant with IEEE802.3at Type 2) power supply device and a LAN cable of Category 5e or higher?

Is the adhesive tape attached during shipment detached? Is there any foreign object inside the product that prevents the camera from rotating?
If the camera unit is unable to rotate when you try to turn it, the power will shut down automatically to protect the equipment.

Is there any problem with the power cable for connecting this product to the power supply unit? (If the cable is too long or thin, this may increase the resistance and prevent the voltage from being properly supplied.)

If no changes have been made to the factory default settings, the IP address is 192.168.0.2, and the subnet mask is 255.255.255.0.

If you have set the [IP Setting] to “DHCP Enable” and if you start the camera on the LAN where no DHCP server exists, you can start the camera with the factory default IP address.

Is the firmware updated?

The Built-in Viewer has an electronic signature for authentication by VeriSign.
If computers are connected to the Internet in the network environment, the digital certificate of the Built-in Viewer can be checked by VeriSign authentication.

For some computers, if [Start]-[Control Panel]-[Adjust screen resolution]-[Make text and other items larger or smaller] is set to “Medium - 125%” or “Larger - 150%”, some parts of the Internet Explorer may be left white with no graphics.

The display may disappear depending on the version of the Internet Explorer.

Is audio transmission in progress?
(When Communicate on the [Audio] page is set to Half Duplex, audio sound cannot be received from the microphone to which the audio cable is connected while audio transmission is in progress.)

Is [Receive] of [Audio Monitor] set to “OFF”?

The camera can transmit a maximum of 40 videos via TCP, and a maximum of 20 Built-in Viewer can be connected to 1 camera.

If [Priority] of [JPEG Streaming] is set to the “Framerate” mode, the frame rate requested by the clients are kept, but the maximum number of streams is reduced.

Multicast streaming may be blocked by the Windows 7 Firewalls. In that case, you can go through the firewalls as follows.

If your computer has multiple network cards, disable the network cards to which the camera is not connected. You can perform this as follows.

If the network has a narrow bandwidth, the frame rate will be limited.

If [Priority] of [JPEG Streaming] is set to the “Client Number” mode, and if the number of streaming requests increases, the images are distributed at a frame rate lower than the preset rate.

If the distribution capability is exceeded, images are distributed at the lower frame rate so that the upper quantity limit of distribution data is not exceeded.

The camera image may not appear smooth at times due to factors such as fluctuations in the CPU and memory load, or network jitter.

Also, distribution capability may deteriorate during recording to the microSD card, or playback or video output from the card.

When you use 3-dimensional noise reduction, in principle, an afterimage can appear if you shoot a moving object, however it is not a camera malfunction.

The port may be blocked by the Windows Firewall.

When [Auto Cleaning] is set to “ON”, this is not an abnormality.

The network bandwidth may be insufficient.

Settings for motion detection, audio detection, and tampering detection cannot be specified at the same time. If one of the detection features (motion detection or tampering detection) is currently enabled, an error message will be displayed when you try to enable the other detection feature.

If there is no valid playback device, the Windows system would assume that an audio driver is not available.

The internal fan is abnormal. Please consult our service center. Also, stop using this unit and turn off the power.

Recording cannot be performed when a microSD card is not mounted.

The microSD cards formatted on the VN-H37U/VN-H57U series cannot be used on this camera. Also, the microSD cards containing videos recorded by this camera cannot be used for recording or playback on the VN-H37U/VN-H57U series.

The screen may not refresh if you move frequently between the microSD card operation screen and the [Advanced Settings] screen.

When the Sense Up function is activated, the frame rate of the video recorded in the microSD card is reduced in order to raise the sensitivity level. This leads to a lower or fluctuating playback frame rate as a result.

This may occur when there are contents with different frame size or frame rate settings.

If the bit rate setting of the encoder recorded in the microSD card is high, the response may be slow.
