First install the SQL Server2012 database and then install the ZKBiolock, and configure the database in the software.

Due to the limitation of the algorithm, a fingerprint reader must be connected in order to initialize the algorithm library and the comparison interface can be invoked.

1.Confirm whether the fingerprint template of the customer is correct 

2.Confirm that the customer's own development process has judgments on algorithm library initialization and fingerprint reader connection. The algorithm library initialization may fail but the client still invokes the comparison interface.

NO, 

FR1200 can only support Ver10.0; FR1200 cannot be connected with C3, because C3 does not support fingerprint.

The VF300 & MB360 products are time and attendance terminals with simple access control. 

The operation of modifying the verification mode on the Access 3.5 software is for the access control. Therefore, the software is set up and the device has not changed.

Only devices with advanced access control can synchronize the authentication settings on Access 3.5 to the device.

It shows "invalid card number" when you try to register card number for a new user.

Need to close parity check of wiegand reader, set parameter ExtNeedParity to 0.

Replace damage fingerprint reader or camera. Pay attention to replacing the correct type of fingerprint reader or camera.

It is due to wrong time stamp, Delete/data/uplog.dat and restart device, run demo, it will start to push up log

For ZKBioSecurity3.0, it offer 30 days for you to test, no need to get the license. You are free at the first 30days after installed. And if you don't think it is enough for you, you could check the demo link in our website to test more

Just click the auto add, and add a new name to device then the device information will appear completely.

The attendance module of the new version of ZKAccess3.5 is chargeable and requires a license. The public license does not include this feature.

Contact technical support to set device parameter: ServerType=0.

Please send us the snapshot of DVR/NVR screen with clear date and time (as

below),we will give you a super password to login in the DVR/NVR.

1. Unmatched lens mount. There are two types of lens mount for box cameras,respectively are CS mount and C mount, the lens and camera must be matched with the same type. 

2. Use Focus in / focus out to control the Clarity. 

3. Check whether the lens or housing gets dirty. 

4. In case of strong light condition, please select electronic iris as the lens type.

1. ICR switches frequently. 

2. The camera’s image looks dark. 

3. Some ripples appear in the image. 

4. The camera might reboot frequently

A simple monitoring system is mainly composed of front-end and back-end and intermediate equipment. The front end is a camera and the back end is a video recorder. The intermediate equipment includes switches, fiber optic transceivers and cables.

4K is 8 mega pixel which is same with four 1080P. At present the common 4K resolutions are 3840 by 2160 and 4096 by 2160 pixels, our devices are 3840 by 2160 resolution as 4K.

H.265 is new video compression technology, the compression performance of H.265 is doubled higher than H.264. For the same image quality, the record space of H.265 only half than that of H.264.

POE (Power Over Ethernet) is provide the power through network cable, without the need of additional power cables for power supply. However, not all of the devices support POE, and only when the devices (switches, NVRs and cameras) support POE, also support same protocol, then power will be supplied. 

There are two standard POE protocols, IEEE 802.af and IEEE802.3at, Our POE Dome cameras and bullet cameras are in IEEE802.3af standard protocol.

In theoretical, power supply distance is the same as the transmission distance of the network cable both are 250m,.due to the influence of cable quality and wire loss, it’s recommended the POE power supply distance not to exceed 80m.

Generally, images’ standard frame is 24fps, when it’s higher than 24 fps the image can be seen smoothly, it’s called real time; when video frame is lower than 24 fps, there will be a sense of stutter, it’s non-real-time. Since the video has P/N format, when the P system reached 25 frames or the N system reaches 30 frames is real-time.

P and N format are two different systems in the traditional TV industry. In order to matched with TV system, for video surveillance industry still use these two formats. The Pal format defaults to 25 frames, which is mainly used in China, Southeast Asia and other regions, and the NTSC defaults to 30 frames, which are mainly used in Latin America and other regions.

NVR is network video recorder, which can implement many functions such as access, preview, setting, control, recording, and alarm to the front-end IPC. 

NVR’s default IP address is 192.168.1.88.

HDMI and VGA.

If you forget the password, the current time of the device (date and time) will be required to

provide technical support, technical support is given by the super password, change your

password to login into the NVR

Click the button to disarm the alarm, and the buzzer will stop. More info need to check the alarm

messages.

Click Start menu to login at first or you can not do any operations.

Login with administrator account, then enter the menu “User manage=> user info”, select the

user which need to modify, then click “modify” to change the user’s password.

Yes, the default port of ONVIF is 8082.

If can not find video record, check the HDD status first, then check the devices time(default year

1970), adjust the time, then continue to record. Finally configure the video record plan.
