First we can look into the appearance of the camera. Normally the dimension of camera with fix lens is less than camera with vari-focal lens. Meanwhile the vari-focal camera has auxiliary components, such as iris control, motor, gear. Secondly we can refer to specification of lens. Generally the focal length of fixed camera is a fix value, shown in the picture below:
Items | Description | Tolerances |
Focal Length | 3.6mm | ±5% |
Aperture (D/f) | F2.0 | ±5% |
Image Circle | 1/2.7" | >6.9mm |
Focus Range | 0.3m~INF |
While the focal length of the vari-focal camera is a range of value, shown in the picture below:
Items | Description | Tolerances |
F No. | 1.5 | ±5% |
Focal Length | 3.6-11mm | ±5% |
Optical Back Focal Length | 6.24mm (In Air) | ±0.1 |
Mechanical Back Focal Length | 13.20mm (In Air) | ±0.1 |
Image Circle | 9 |
Invoke sensor settings by right clicking on live video, change to fixed mode and then adjust the value under Day-night settings.
This could be caused by IP conflict, please change the IP address of one device.
As DHCP is opened by default, if camera is not allocated with IP by DHCP service, its default IP is 192.168.0.120, and login account/password: admin/admin
Right click the live video, select sensor, switch to debug mode and set it at the image menu:
At sensor setting menu, you can set at most 4 scheme for image setting and period, After the setting is completed, switch the mode back to standard mode, then the camera will apply the image parameter according to which time segment it was in, if time is not in these 4 scheme, it will apply the default setting, If time cross two different scheme, the previous scheme will work.
please refer to the table as below
Focal Length | Field of view (e.g) | Recommend monitor distance |
2.8mm | 98.5° | About 3 meters |
4mm | 79° | About 6 meters |
6mm | 49° | About 10 meters |
8mm | 40° | About 20 meters |
12mm | 23° | About 30 meters |
16mm | 19.2° | About 50 meters |
25mm | 12.4° | About 80 meters |
※Field of view angle varies from different model, refer to the official website for accurate parameter |
When the camera is installed at unstable condition (such as at vehicle or tree, the anti-shake function will increase stability of image
Enter the Sensor setting interface, adjust the white balance mode at WB menu
1. Make sure the hard disk is well (check by replacing with another new one)
2. When hanging with multiple hard disk, note that the power supply can meet the requirement, monitoring specialized hard disk is more stable with smaller starting current, lower working speed and consume less power than consumer hard disk, if power supply is not enough, the hard disk will not be able to work, which result in disk unrecognized and recording failure.
3. If NVR can read the disk, please format the disk first, as in most cases, repeating read and write will generate disk fragmentation or bad sectors, a formatting process will skip or repair the bad sector.
Yes, it is accessible for those third-party devices which support ONVIF protocol.
Please connect the NVR to Router, and make sure the DHCP function of router is enabled,and open the function of automatically getting IP on NVR network setting menu
RTSP format: rtsp://ip:port/snl/live/cameraid/streamid
Example: rtsp://192.168.1.19:554/snl/live/1/1
1. please check if the username and password is correct when adding the camera
2. network cable issue, please use CAT5e or CAT6e cable, It is recommended to use 8 cores for the wire, the POE cable sequence for data transmit is 1/2/3/6, for positive power is 4/5, for negative power is 7/8, the distance of cable should be controlled around 70 meters
3. camera is not powered on, please check if camera support POE
If camera is sunell camera, and you don't know the ip, please connect camera and PC at same local network(or directly connect camera to PC), using IPsearch tool to find the correct IP, then add it to NVR; If camera is from third party, please check if they provide tool to search the camera IP, Then add it to NVR by input the IP, user name and password of camera
1. Power supply of IPC is not stable, for example, IPC will consume more power at night with IR Led enabled, which may cause electricity insufficient.
2. Network bandwidth issue, the switcher performance is insufficient
3. Camera issue:
If only the specified camera or channel has this issue, we recommend you replace with a normal camera to check
If offline issue happens randomly with all channel, we suggest checking reason 1 and 2
If offline happens to all channel at same time, please check if the camera is powered by centralized supply, please check the power status

1. If you uninstall the old version of sunview manually, and then try to install new version, maybe you will have this problem
2. It means you didn't uninstall the old version completely, so some files still save in the registry.
3. open the regedit.exe on the Windows
4. go to HKEY_LOCAL_MACHINESOFTWAREWOW6432Node, find the folder "vmSystem", and delete it directly. then you can install the new version correctly.
1. CMU (central management unit): It mainly deals with messages. Integrate and manage messages that communicate between servers and clients.
2. IAU (Intelligent analysis unit): It mainly analyzes and processes the data of face and license plate of intelligent module, such as AI module of face recognition, license plate recognition and intelligent recognition.
3. MDU (Media Distributor unit): It mainly transmits the audio and video stream of the equipment and the intelligent analysis data to the client.
1. The antivirus software may prevent installation. in this case, close the antivirus software and reinstall the software.
2. If the installation still fails even you turn off the anti-virus software, it may be the problem of the installation package, such as abnormal installation script, database damage, etc. Need feedback to us for processing.
127.0.0.1 is the return address, which also refers to the IP address of the PC where the SUNVIEW is installed. If the server is installed on the local computer, it can access the server through the default IP address of 127.0.0.1. You can also enter the IP address assigned to the PC. For example: 192.168.1.168
The longest transmission distance of HDMI is usually 15 meters.

setting detection area
1. Face detection: Detect the face of human
2. Up body detection: Detect face and shoulder part of human

4. Display trace: Display the information of tracing
5. Confidence coefficient: Face detection sensitivity, the value range is high, medium, or low, the larger the value is, the higher the sensitivity. The higher the sensitivity value is, the higher the detection rate will be, but the more false detection may occur, such as the false detection of the patterns on pedestrian clothes to adult faces.
6. Smallest pixel: When the pixel of the face in the image is less than the set value (the minimum pixel for face recognition), it is not captured.
7. Snapshot mode: There are two types timing and optimal.

1. License plate must be readable and well lit
2. License plate dimensions must be at least :
* 150 pix for rectangular plates and 100 pix for two-row plates (for Russia, Kazakhstan, Armenia, Uzbekistan, Serbia).
* 130 px for rectangular plates and 70 pix for two-row plates (for all other supported countries).
3. Allowed tilt 5 degrees (clock and counterclockwise).
4. Vertical angle and Horizontal angle: should not exceed 30 degrees:
5. Example of good license plate at day and night
1. It may be the DVR recognizes the input signal source incorrectly and needs to plug and unplug the BNC cable again.
2. It may be the problem of coaxial line, so the coaxial line needs to be replaced
3. The DVR may not support the input source of the coaxial HD camera (including signal mode, resolution, frame rate). It is necessary to switch the signal mode to CVBS through the five-way switch of the camera, and then switch to the correct input source through the OSD menu of the camera.
1. Call through UTC function of DVR
2. Call through the five way switch of the camera
The camera supporting coaxial signal switching to analog signal will have a five way switch as shown in the figure. If analog output is required, press the set key for 5 seconds to switch the source to CVBS. If there is no five way switch, the camera only supports coaxial signal output.
The twisted pair is used to tranmit HD signal, and the picture is easy to be disturbed, it is not recommended to use twisted pair to transmit HD signal.
HD signal belongs to high definition signal, which is more susceptible to interference than common CUBS signal
1. Confirm whether the power line and BNC line are in parallel, so that the AC (220V and above) will affect HD signal, and separate the pipe
2. Bypass the interference source;
3. add jammer, reduce interference
4. It is recommended to transmit the signal through optical fiber
