Common problems and solutions of IPC network cameras

We often have various problems when connecting IPC network cameras. The following summarizes the problems and solutions.

1. Question: How to use IE browser to connect to IPC?

Answer: Use the IE plug-in of IPC to set the IPC device, but first make sure that the computer using the IE plug-in and the IPC device are in the same LAN. When you are not sure, you can use the network command "ping" to check whether the network is connected. Then follow the steps in the manual.

2. Question: Why is the IPC image normal during the day and dark at night?

Answer: The normal daytime image of the IPC indicates that the IPC is working normally. If the night vision is dark, you can first check whether the IPC is set to the constant color or color mode (the time setting is wrong) through the video recorder or JNVR. You can set it to automatic or regular color mode. (Correct time setting), or perform a factory reset; if it is impossible to switch after the upgrade, please download the corresponding upgrade file from the official website to upgrade and repair.

If the problem persists after the correct setting, please check whether you hear the sound of CUT switching after power on, cover the photoresistor, whether the infrared light is turned on, if the infrared light is not turned on, if not, it needs to be repaired;

3. Question: What should I do if the IPC or NVR shows that the password is wrong and I forget the correct password?

Answer: You can record the displayed error code, and obtain a temporary account password through the error code in the online technical support on the official website or self-service in Xiaowei Community, and reset the account password.

Note: The error code will only be displayed when you operate locally with the video recorder, or the remote video recorder and camera are on the same network segment, and the temporary password obtained is valid for three days.

4. Question: What should I do if I find that the pan/tilt is out of control after the dome camera is installed?

Answer: To troubleshoot and solve this problem, please start from the following three points:

① Check whether the image of the dome camera is smooth or not. It is best to use the network assistant of the video recorder or the PING function of the computer to check whether there is any packet loss. If so, you need to check whether the network cable or the crystal head is not well done. Or the processing capacity of the switch is insufficient.

② If there is no problem with the network of the dome machine, and the control at night is not good, or the gimbal rotates by itself, you need to check the power supply of the dome machine. Try not to use the power extension cable and self-provided adapter, which may easily affect the speed of the dome machine due to insufficient power. tower.

③ If you are using an onvif video recorder or client, you can use the Zhongwei HD monitoring system to test whether the speed dome is normal. If the Zhongwei HD monitoring system can be controlled normally, you can judge that it is caused by the onvif protocol, and you can choose Zhongwei products or contact us for optimization.

5. Question: How to set the IPC stream?

Answer: There are two ways to set the IPC stream:

The operation steps of setting the IPC code stream size in the high-definition surveillance system and Cloud Vision software are as follows:

a. Right-click the monitoring screen where the IPC code stream needs to be set, and left-click the pop-up right-click menu to select the "Remote Setting" submenu, and the system will open the function panel of the remote setting.

b. Left-click the "Bit Stream Management" button, and the system will open the "Camera Settings" interface, where you can set the three bit stream sizes of the IPC.

6. Question: Why can't the NVR search for the IPC?

Answer: To troubleshoot and solve this problem, please start from the following three points:

① Use JNVR to search, if you find it, modify the IPC to a fixed IP that requires a network segment, and turn off the IP adaptation of the IPC;

② If you can't find it, use BOOT to upgrade, put the IPC and computer under the same router or switch (direct connection cannot be upgraded through boot);

③ If the above still can't solve the problem, replace the network cable, repeat the operation of the third step, if it still can't be found, return to the factory.

Before the above solution, there are several aspects that need attention: 1. Check the power supply, or cover the camera with your hands, and observe whether the infrared is turned on, and ensure that the IPC hardware is normal; 2. There is also an IPC that supports audio, it is recommended Customers don't want IPC and pickup to share the power supply. Generally, customers will choose 2A power supply, so the IPC power supply is insufficient. If they must share it, they need to provide 4-5A power supply.

7. Question: I can’t find the IPC with the NVR or the client of the ONVIF manufacturer?

Answer: First, make sure that JNVR or CV can search for IPC normally. If not, use BOOT to upgrade. IPC and computer are placed under the same router or switch (direct connection cannot be upgraded through boot). ,; Secondly, if you can search normally, upgrade the IPC and NVR; Finally, if you cannot search and record the manufacturer of the NVR and the model and version number of the NVR, inform the customer service staff.

8. Question: What should I do if there are lights near the IPC at night and the black and white mode cannot be switched and the image is blurry?

Answer: When there is light near the IPC at night but the light is not very strong, the IPC may mistakenly think it is daytime, so the black and white mode is not switched. At this time, the image will have a lot of noise (blooming) due to insufficient light. When encountering such problems, there are the following two solutions.

① When installing the IPC, please try to avoid direct light on the IPC, try to let the light source follow the IPC, and keep a certain distance from the light source;

② If such problems cannot be avoided during the installation process, you can set the IPC in the video recorder or computer software to the function of timing color. Set the time period, the image will be colored in this time period, and the image will be black and white in the rest of the time. The specific setting steps are: click the drop-down menu of day and night switching, and select the timing "color function".

9. Question: Why is the screen frequently turned on or off after the NVR is connected to the IPC?

Answer: When the screen is frequently connected or disconnected after the NVR is connected to the IPC, please check the cause of the problem from the following three points:

① Determine whether the number of IPCs connected to multiple switches is balanced. If not, please adjust the number of IPCs connected to each switch to distribute network resources evenly;

② Determine whether the network bandwidth of the NVR device is sufficient, if not, please connect the NVR device to the Gigabit Ethernet port of the switch;

③ Make sure that the crimping of the crystal head of the network cable is good. If not, please redo the crimping of the crystal head of the network cable.

10. Question: How to set the tripwire detection and area intrusion of intelligent analysis?

Answer: If you are using Zhongwei NVR, you can set it through system settings→alarm→intelligent analysis; if you are using Zhongwei HD monitoring system or cloud vision network monitoring system, you can set it by right-clicking remote setting→intelligent analysis set up.

11. Question: How to wire the IPC over a long distance?

Answer: The length of the network cable between the IPC and the next switch should not exceed 100m. If the actual environment exceeds this distance, the following three points should be solved:

① If the actual distance is between 200 and 300m, you can consider using multiple switches in series, but this method will also interfere with multi-stage amplification, so use up to 4 high-quality switches, and do not use between each switch. More than 100m, this method is low cost but the effect is not good.

② If the distance exceeds 300m, it is recommended to use optical fiber and optical transceiver. This method has long distance, stable transmission and low cost.

③ If the distance between the monitoring points is long and wiring is inconvenient, consider using a wireless method.

12. Question: The network port light of the IPC is on, but I can't find what to do.

Answer: If the camera suddenly loses power and network during the upgrade, the upgrade fails, or other reasons, the IPC cannot be found on the NVR or PC, and the network port light of the IPC is flashing normally, you can use the JNVR built-in The IPC upgrade tool for boot repair. The upgrade file can be found in the corresponding upgrade package on the official website.

13. Question: Why does the infrared light flicker at night, and the network is intermittently disconnected?

Answer: When the infrared light flashes only at night, and the network is intermittently disconnected, please check and confirm whether the voltage is stable. This happens when the voltage is unstable.

14. Question: Why does the IPC time keep changing?

Answer: The IPC itself cannot store time information, so when it is powered off and restarted, it is usually adjusted through the connected video recorder or computer client. Therefore, if you find that your IPC time keeps changing, you should first confirm whether there are multiple The recorder or client is connected to this IPC at the same time, and their time is inconsistent. If this is the reason, it is best to set the time of all recorders and clients to be the same. If your device is connected to the public network, you can turn on the network time adjustment.

15. Question: How to solve the flashlight effect when the screen appears bright in the middle and black around?

Answer: The flashlight effect appears during night vision, mainly due to the mismatch between the selected millimeter and the environment scene. The smaller the millimeter, the larger the angle of the infrared lamp cup. When the flashlight effect occurs, the IPC can be slightly too high and do not direct There should be no obstacles in front of the lens on the wall or the ground, or use an IPC with a small millimeter.
