Entering and exiting the face camera

Answer 1

The following is some information about the entrance and exit face camera (a camera that can be used at the entrance and exit to take face photos):

** I. The features and functions of different brands of cameras **
1. ** Tiancheng Shengye Dual-Mode Face Recognition **
- This was the world's first dual-mode smart Face Recognition device. It used multi-light source fill light technology, with near-infrared and visible light video capture functions, combined with the third-generation Face Recognition algorithm (TesoFace V3.0), which could accurately perform Face Recognition and image capture under different lighting conditions. It was a high-definition camera that integrated video capture, storage, transmission, and management functions. It also had a rich software development interface that could be closely integrated with third-party application management systems. It was widely used in many fields such as image acquisition, video recording, Face Recognition security authentication, and so on.
2. ** Haikang camera (snap camera)**
- The model with "-2CD" was basically a snap camera. This type of camera came with a face detection function. Ordinary Haikang cameras also had a face detection function, but it needed to be activated manually. Its internal face detection, human shape monitoring and other functions can be used for application development. The camera comes with a web application that can be used to set up alarm push and support the ftp and ftps protocol.
3. ** Mid-century Face Capture Machine **
- It was affordable and had a variety of functions. It had a two-way voice intercom, black light night vision function, support for memory cards, 5.5 million pixelation, PoE power supply, and more. It was able to perform Face Recognition capture. By drawing irregular areas, as long as someone passed by, they would leave clear photos and corresponding before-and-after videos. When used in key entrances and warehouses, coupled with license plate recognition and flame detection cameras, it could improve the overall security competitiveness.
4. ** Haowei Security Face Recognition Capture Cameras **
- It could track, recognize, and magnify human faces. Once someone entered the surveillance range, they would capture their faces. It has the functions of multi-face detection, tracking, and amplification. It can detect, track, magnify, and transmit moving faces. The amplification factor can be automatically calculated according to the number of people and relative positions. It uses a large-caliber lens with a large amount of light passing through and a clearer picture. It also has a voltage stabilizing protection circuit design. It is suitable for indoor entrance and exit monitoring of shops, hotels, shopping malls, and residential areas.

** 2. Face Recognition technology related functions **
1. ** Face detection and facial features positioning **
- It could detect the faces in the picture and give the accurate location of each face and 105 key points of information. It could output the number of faces, the rectangular coordinates of the face, the pose of the face, the coordinates of the center of the double pupils, the face confidence level list, and other information. It supported the comprehensive quality score of face obstruction, illumination, blurriness, pose, and noise. It also supported the detection of multiple pose angles in photos containing multiple faces. It could detect faces in 360-degree rotation and face detection in a maximum of 90-degree left and right. The key points of the facial features in the image were extracted in the millisecond-level and 105 key points were located.
2. ** Face Attribute Identification **
- On the basis of authorized face detection, it could identify the four attributes of the detected face: gender (male/female), age, expression (smiling/not smiling), and glasses (wearing/not wearing). It could also return the 1024-dimensional deep learning features of the face for high-performance Face Recognition.
3. ** Face comparison and search **
- Face comparison 1:1 could be based on two authorized images, detect faces and select the largest face for comparison to determine whether they were the same person. At the same time, it would return the coordinates of the rectangular frame, the confidence level of the comparison, and the confidence threshold of different error rates. Face Search 1:N is based on images or videos that have been authorized to be imported and compared with the registered library owned by the customer. It is suitable for face login, VIP Face Recognition, and other scenarios. It provides the SIM call method, supports non-interaction or motion detection, supports multi-platform, CPU, and CPU computing modes, and is flexible to deploy.

** 3. Other related features (some cameras)**
1. ** Special Function Mode **
- Some cameras supported a variety of face capture modes, such as fast, interval, and after leaving (with distance and quality selection). The number of shots could be set. It also supported face area recognition, area shielding, list management, alarm settings, comparison records, and many other parameters.
2. ** In terms of technical parameters **
- It can detect up to 32 faces per frame, and it can detect faces between 30*30 - 500*500. It supports uploading face images and original images. The quality of the face image can be adjusted. It supports the management of up to three face libraries, up to 22400 face libraries, and supports multiple defense time settings. The total storage space of the face library is 16GB, and a single face supports the range of 150*150 - 960*960. It supports black-and-white list comparison, VIP list database comparison, non-face database personnel identification and alarm output. Some of the cameras also supported the face smart exposure mode, with a wide dynamic range of 120 decibels. The face was still clearly visible in the backlit environment, and there were different capture scene modes for backlit and normal environments. Some cameras had built-in electric lens zooming lens, which was easy to operate and the zooming process was smooth. There was also a built-in high-efficiency infrared array light, which was low power consumption. With the ICR infrared filter, it could automatically switch between color and black mode to achieve day and night continuous capture. It also supported Smart infrared to prevent the image from being overexposed or underexposed. Different focal lengths of the lens corresponded to different capture distances.
