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.

Fingerprint template can't convert pictures. The binarization process of extracting fingerprint feature points from a picture and saving it as a fingerprint template is irreversible.We can get the original fingerprint image from the fingerprint reader through the SDK interface ZKFPM_AcquireFingerprintImage. It does not support converting from a fingerprint template to a picture.

Our biometric identification SDK does not involve user IDs.Since a person has 10 fingerprints, we only have a finger index, which is a 32-bit unsigned integer, a pure number that does not exceed 9 in length. Our SDK only cares about the information he collects, then compares it and does not care about logical data.

Need to use PIV standard SLK20R

ZKFingerSDK is not provided, there is another conversion library that can provide conversion interface.However, only ZK10.0 fingerprint templates are currently supported for conversion to ISO/ANSI templates. ISO conversion to ZK fingerprints is not supported.

When the command issued a fingerprint, base64 format encoded fingerprint needs to be decoded

There is a field in the structure of user information for how many fingerprints the user has stored.If a fingerprint is deleted, the word value of the field is reduced.In addition, the index inside the module is self-maintaining. If you want to or fingerprint the index number, you can only read and download all fingerprint templates to query.

Unregistered class, confirming the client's operating system and the number of used SDK bits, suggesting that the client's debugging platform be changed from x64 to x86

Here comes the instructions in our development documentation. 2. Development Environment Setup 2.1 Importing libzkfinger10.so libzkfinger10.so is a fingerprint algorithm library, which supports the fingerprint template extraction, comparison, storage, and deletion functions. Enter the libs/armeabi and libs/mips directories and check whether libzkfinger10.so exists. If yes, the interfaces of the ZKFinger SDK can be normally used. If no, contact ZKTeco technical engineers.

You need to install the Biokey.ocx control in Delphi. After installing the ZKFinger SDK5.3 Lite driver, Biokey will be stored in the program directory, for example: C: \ Program Files \ FPSensor \ Biokey.

The current check found is the C++ runtime library that has been installed by the customer

Please update the latest ISSonline SDK test. SLKID 1.4 or less and 1.4 or more are different. Old SDK Under 1.4 Firmware USB2.0 fetched original map at SDK layer probe speed acceptable Before 1.4~2.0, the firmware used USB1.1. If you continue to transfer the original image, the speed is very slow. After the SDK upgrade, the correction map is read. The data is much smaller than the original image and is not so slow.

1) Confirm the fingerprint reader firmware version, which can be read using a small program. 2) Confirm the software used and its ZKFinger SDK version. 3) Is the released ZKFingerSDK 5.3Lite demo version normal? 4) Provide test steps, video or error screenshots as much as possible.

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.

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).

Only the network camera has POE. 1,2,3,6 are the data wire and 4,5,7,8 are idle. Two methods can be applied. With 8-core wire, one method is using 1-4 cores for both power supply and data transmission. Another method to use 5-8 cores for power supply while the rest for data transmission.

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.

ONVIF is committed to providing and promoting open interfaces to the security industry for effective interoperability of IP-based physical security products.

H.264+ technology is a kind of intelligent algorithm developed by Hikvision. It is a remarkable encoding technology which focuses on the features of the surveillance video and is optimized based on the H.264/AVC. H.264+ lowers the bitrate of the surveillance video greatly so as to save the system cost.

DVR/NVR is a management device which realizes the function of centralized storage, local live view, search, playback and other functions. The main difference between DVR and NVR is the function of encoding. DVR is an encoding unit, but NVR does not have this feature.

After the video is compressed, a stream is generated. Bitrate (bps): quantity of bit stream per second. Bitrate type: Constant Bitrate (CBR), Variable Bitrate (VBR). Stream type: video, audio, video & audio complex stream.

The main stream with high resolution and full frame rate can be used for main monitoring and recording. The sub stream with lower resolution can be used for mobile monitoring. Some devices support third stream which offers more flexible choices.

Please install the HDD properly, no gap with the interface. Please install recommended HDD, eg. Seagate, WD, TOSHIBA, SANSUNG, HITACHI (generally capacity: 1T, 2T, 4T, 6T, 8T).

Please Power off ZKTeco IP camera, and then power on it again, its account is still admin, and password will be back to 123456.

Face Detection: Face Detection function is fulfilled by the camera. The face features such as eyes and mouth would be recognized. The detection highly demands the size of face shown in the image and the angle to the lens. We recommend users have the camera installed close to the desired detection region and make sure people face the camera directly. Notice: Face Detection is different from Face Recognition. In Face Detection, the detection of faces in the whole image would trigger the alarm and notify surveillance center. The regions of detected faces would not be captured. The Face Recognition Camera is able to capture face images and upload to server for face comparison.

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.
