DVR4000 monitoring system issues. Of the 6 channels, 1 is not displayed.

There are a few possibilities. First change the channel with the image to the channel without ** channel to see if there is an image,If there is, it is a front-end camera problem,If there is none, it should be the channel of the card hanging。。 You can try reinstalling the driver, if it doesn't work yet. Send it for repair!

。。。Originally, all 6 pictures had images?

If there are still only 6 images in 36 screens, you can just set the window to 6 screens.

If you don't have 6 screens, you can set it to 9 screens. It's not bad.

Update the driver, restart the computer!

Check whether the driver installation is normal, and in the hardware device information of the system, see if there is hardware information for another channel.

The chances of the camera's power supply breaking are very small. Hehe, re-drive under the software re-installation. Just did the system.

It shouldn't be much of a problem. Such a problem has been dealt with before. Three years ago.

Now I forget how I got it. See if the braid on the back of the computer is plugged in.

Have I installed a lot of surveillance? You can try this problem, change the monitoring probe that can be displayed to the probe line that can't be displayed. If it can't be displayed, it's a line problem.,You can ask me again after trying.。

Hello landlord,If the channel that you can't display is useful if it's useful to change the channel that can be displayed,It means that the channel that you can't display should be closed by you.,You can open it in the settings screen!! Thank you.

1. Determine the location of the fault: Swap the unimaged signal with the imaged signal to see if the fault is replaced. If it is replaced, check the signal (camera and its wiring), and if the screen display can still be determined to be a DVR fault, proceed to the next step.

2. DVR fault detection: measure whether the resistance value to the ground is 75 ohms for the non-displayed signal BNC head, which can be compared with the normal channel, if the resistance value is inconsistent, it is necessary to disassemble the machine to check the resistance and channel IC in the internal input circuit. If the resistance value is 75 ohms, restore the factory settings (of course, you can also do this step first).

3. If you don't understand, you can contact me

First find the two machines that don't display the image, check whether there is power, and then check the connector at the end of the video recorder, open the street to see if the wiring inside is connected (open circuit or short circuit), if there is no problem, check the connector at the end of the camera, the inspection method is the same.

The computer is connected to the DVR, and the DVR has its own IP address, which must also be in the same network segment as the computer.

1. Check the software registration status.

2. Check the driver installation. Device Manager to see if there are any exclamation marks, or unknown devices.

3. Whether the computer configuration meets the minimum requirements.

Take another look at this.

Whether you are using an industrial computer or an Enpan video recorder, if you have a new installation of the system, it should be able to solve the Enpan video recorder, you will buy an irregular manufacturer, and you can also solve it by changing the motherboard, but there may be similar problems, it is recommended that you replace a regular manufacturer.

2.Cards purchased online, not being serviced, or unable to find the seller. Take the card off and take a photo, the card usually has a serial number on it, one or two sets, copy it down. Go to this code and ask for help.

3. The configuration of the host is written clearly by a friend who understands the computer.

Or hi us.

The capture card driver is not installed.
