Why does the device just show embedded NVR in monitor and restarts every few minutes?
Take out all HDDs from the device, and disconnect all the cameras,
If it works, you should check the HDD or camera. The DVR is in good condition itself;
If it doesn’t work, it means you should check the power of DVR or change the monitor with high resolution;
If user tries all the above steps and still in vain, please contact your seller for repair.
What does 4K mean?
The name “4K resolution” refers to a horizontal resolution of approximately 4,000 pixels. It has been developed into a variety of standards. The DCI 4K resolution standard (4096 * 2160 pixels) is widely respected by the film and video production industry. Besides, UHDTV standard (3840 * 2160 pixels) is also popular which has twice the horizontal and vertical resolution of 1080p (as shown in the figure below)
What is TVL?
Generally speaking, the image on TV could be divided into many horizontal lines which are also called TV lines.A higher number of the horizontal lines means that a camera will be able to render images with more details.
What is Resolution?
Resolution is usually measured by the number of horizontal and vertical pixels. It can be expressed as number of horizontal point * number of vertical pixels. In a fixed plane, the higher resolution could provide better image.
What is ONVIF?
ONVIF is committed to providing and promoting open interfaces to the security industry for effective interoperability of IP-based physical security products.
How to add and connect the IP Cameras?
Before you start, please ensure the network connection is valid and correct.
- In the device local interface, you may select an idle window in the live view mode and click ‘plus’ icon in the center of the window to pop up the adding IP camera interface.
- Also, you may click Menu / Camera / Camera to enter the camera management interface and add cameras from the camera list.
For more details please refer to the product user manual.
Why there is noise of audio in live view or playback?
Check whether the audio of camera in web interface is normal.
Decrease the IPC audio-in. Please go to IE control page to decrease the audio and try again.
Make sure the cable connecting is right, and the audio equipment is matched with the NVR technical standard.
Is it possible to connect a HIKVISION IPC to a third-party NVR? Or a HIKVISION NVR to a third-party IPC?
Yes, it is possible. All Hikvision NVRs and cameras are self-adaptive with ONVIF protocol, so it is accessible for those third-party devices which support ONVIF protocol.
What should we do if we experience playback lag via single channel on local GUI?
Playback lag is usually caused by the network packet loss or insufficient hard disk performance.
Step 1:
Please check whether the channel has lags when live view via single channel.
A、If the channel has lags when real-time preview, it may be caused by non-full frame rate or the network condition. Please check the frame rate and the network condition.
B、If the real-time preview of the channel has no problem, the playback lag may be caused by insufficient hard disk performance. Please test according to the third step.
Step 2:
The analysis of the real-time preview lag is listed as follows：
A、Please make sure the main stream frame rate of IPC has been set as full frame rate.
B、Please check if it has the network packet loss problem or VLC preview lag based on VLC preview. If it exists both of the network packet loss and VLC preview lag, please test your network.
Step 3:
The real-time preview of the channel has no problem，the analysis of playback lag is listed as follows:
A、This kind of situation is likely to be caused by insufficient hard disk performance.
The operations which are related with hard disk read/write would appear lag, such as visiting playback interface and log information etc.
B、The video works well on PC which is downloaded from NVR.
C、If NVR installs many disks, please try to play back video files during different time periods. The time span should be as long as possible. And please make sure the playback files and the playback lag files are not in the same disk. Playback files in different disks are usually without lag.
If it meets the above three points A、B、C, we could remove the corresponding hard disk and replace with a new hard disk.
Step 4:
Please provide all the necessary information such as models，versions and specific issue description of NVR and IPC to the technical support.
What should we do if we experience lag when multi-channel play back?
Multi-channel playback is usually caused by the decoding performance of the device.
Description of step 1: Please check how many channels play back simultaneously would appear lag.
Description of step 2: Please provide all the necessary information such as models，versions and specific issue description of NVR and IPC to technical support.
Local live view lags
Troubleshot procedure:
Steps:
- Please go to Record / Parameters / Record to check if the live view stream is full frame rate.
- Check network conditions. The possible reasons are network congestion and packet loss. We may use ‘Ping’ command to check if network congestion exists. Besides, we may check if lags occurs in the record which usually caused by packet loss.
- Check if the problem is caused by IPC. We may check the IPC live view in IE browser, if the same problem exists, please refer to IPC troubleshot
Local live view black screen
Trouble-shooting procedure:
- Check if there is any error hint. Please move to step 2 if no error hint. If the error hint is ‘No link’, it indicates the problem is caused by IPC off line, please refer to IPC troubleshot. If the error hint is ‘No resource’, we can lower main/sub stream resolution to solve it.
- If there is not any error hint, we could upgrade IPC firmware version and test again.
- Besides, please go to Configuration / Live view / View to check if the IP channel is banned (‘X’ means banned).
- If the problem remains after step 1 and step 2, please contact with technical support for further support.
Why is the DVR/NVR beeping?
In the DVR/NVR local interface, go to Menu / System configuration / Exception. Go through the list of exception type. Select each exception type and un-check AUDIBLE WARNING if it is checked for that exception. If the unit stops beeping, then the current exception selected is the cause of the beeping.
Common issues for the DVR/NVR beeping are the following:
HDD not formatted or in error state, IP address conflicted, Record/Capture error, Network disconnected …
