Common high frequency problems of Hikvision cameras and recorders

In order to conveniently solve the problems encountered by customers in the use of products, we have sorted out common high-frequency problems for your reference.

01 Q: The camera connected to the VCR often goes offline?

A: Possible situation:

1. The power supply of the camera is unstable, for example, it is normal during the day, and it is easy to drop off at night; it is recommended to provide a stable power supply nearby.

2. Network line problems, the exchange performance of the switch is insufficient; it is recommended to replace the network cable or switch test.

3. Device IP conflict, IP conflict between recorder and camera or IP conflict between cameras; it is recommended to modify the device IP. (Reply to "How to modify the device IP address" for detailed instructions)

4. Camera failure; it is recommended to communicate with after-sales to check.

If it is the case that several fixed cameras are disconnected, you can check through the cross-experiment and replace the normal camera wiring with abnormal ones to determine the problem; you can also check whether there is IP conflict between the cameras and modify Camera IP.

If the non-fixed camera is disconnected, it is recommended to check 1 and 2 of the possible causes.

If all cameras are disconnected at the same time, is the camera centralized power supply, and the power supply is abnormal? Or the switch works abnormally and the camera drops simultaneously? Or the network port behind the recorder is abnormal; in addition, you can check whether the recorder and the camera IP conflict, and modify the recorder / camera IP.

02 Q: What should I do if the camera shows insufficient network bandwidth?

A: The total access bandwidth of the camera has exceeded the access bandwidth of the recorder. It is recommended to reduce the upper limit value of the code rate of the recorder, and adjust the path recorder "Main Menu-Recording Configuration-Encoding Parameters, Upper Rate Value", each channel needs to be reduced.

03 Q: Hikvision can't find the camera?

A: If it is a Haikang camera and you do not know the IP address, you can download the SADP software on your computer and connect the camera and computer to the same local area network to search. Confirm the IP address and add it to the recorder. SADP download address: ftp: // 400sadp: vision. com

If it is from a third-party manufacturer, please confirm with the camera manufacturer whether there is software that can search the IP address of the camera. After confirming the IP address of the camera, add it to the recorder, enter the IP address of the camera, user name, and administrator password (this is the password of the camera).

04 Q: How to connect Hikvision's video recorder with wireless camera?

A: The IP address of the wireless camera needs to be set on the same network segment as the IP address of the recorder. The next steps are the same as the steps of adding a network cable to connect the camera. You can get more information by replying to "Camera Wireless Configuration" and "How to add a camera to the recorder".

05 Q: What should I do if there is sound in the preview, but no sound in the video?

A: There is no sound in the playback screen. It is a priority to confirm whether the recording audio is turned on. The rest is the same as the preview.

Local setting path of the recorder: Select "Main Menu → Recording Configuration → Encoding Parameters", select the recording parameters, set the "stream type" to composite stream, and check the recording audio of "More Settings".

Webpage setting path: Go to "Configuration → Storage → Storage Configuration → Recording Plan", and tick "Record Audio" in "Parameters".

06 Q: How to adjust the encoding resolution of the recorder?

A: You can check the resolution in the main menu of the recorder-recording configuration-encoding parameters, or you can adjust it to the parameter value you need. Note that adjustment will affect the recording effect!

07 Q: What does dual stream mean?

A: One channel of video image outputs two independent code streams through the video encoder, one code stream is used for local recording, and the other is used for remote transmission. This has the advantage that: under the premise of maintaining local high code stream recording, remote can use low Some code streams are transmitted in order to maintain the smoothness of network transmission. The dual stream uses a high bit rate stream (main stream) for local HD storage, such as QCIF / CIF / D1 encoding, and a low bit rate stream (sub stream) for network transmission, such as QCIF / Sub-QCIF encoding, taking into account both local storage and remote network transmission. Dual stream can realize two different bandwidth stream needs for local transmission and remote transmission. High bit stream can be used for local transmission to obtain higher HD video storage, and lower stream can be used for remote transmission to adapt to CDMA / ADSL, etc. Network to obtain higher image fluency.

08 Q: How to access Hikvision equipment upgrade steps when visiting the website?

A: You can enter the IP address of the device in the web interface to access it, and then choose to upgrade in the configuration and system maintenance interface. Browse the upgrade file and click upgrade. If the upgrade file is a compressed file, you need to decompress it

09 Q: How to map double-layer routing ports?

A: Case: If the lan port of router 1 is connected to the lan port of router 2, router 2 is equivalent to a switch, and port mapping and domain name resolution are set directly on router 1.

The second case: If the lan port of router 1 is connected to the wan port of router 2, you need to do port mapping on the two routers. The specific method is as follows: the port mapping address on Router 1 is the wan port IP of Router 2, and the port mapping address of Router 2 is the IP address of the recorder's intranet. For other multi-routing methods, and so on, the IP address of the upper-level route map is the wan port IP of the lower-level route, and the address of the later-level route map is the IP address of the device.

10 Q: How to turn on the backlight compensation function?

A: Hello, if the device supports backlight compensation, you can log in to the IP of the device in a computer browser on the LAN, and select the compensation area according to the position of the actual video scene is too bright or too dark to avoid this area being too bright or too dark. The user can also Select a custom area. Reply to "How to access the camera from a webpage" for login instructions.

For older versions of devices that support backlight compensation, you need to access the camera through a web page. In the configuration-image-backlight-backlight compensation area, choose to open, you can customize the area.

For the new version of the device that supports backlight compensation, you need to access the camera through the web page, in the configuration-image-display configuration-backlight-backlight compensation area, select open, you can customize the area.
