high-speed download for a variety of digital video monitoring and recording equipment (such as DVR, NVR, IP and SAN). It supports simultaneous operation of multiple digital video monitoring and recording equipment, including such functions as recording check-up, preview and download. The product has two types of hardware, namely, single-screen standard edition and double-screen professional edition. Featured by high compatibility, real-time video preview, batch setting of recording download tasks, multithreading and multichannel high-speed download, and unattended download, the product can help put an end to the low efficiency in collection of vast amounts of video recording in a quick and convenient way.

Video Prospecting Toolbox, characterized by strong mobility and portability, is a set of complete video prospecting and collection device. It is produced by turning high-density polyethylene materials into a 480*340*165mm rotational moulding box that integrates video download alliance, video copier, mobile hard disk, hand-held GPS terminal, fast player, hard disk adapter, and laser range finder. It collects on-spot videos, the longitude and latitude of monitoring sites and on-spot photos, and measures on-spot distance in accordance with the needs of on-spot prospecting of video investigation, allowing users to easily cope with the collection of multifarious information on the spot of video prospecting.

The time and space analysis standard edition adopts the design of a portable suitcase. It is able to avoid the vibrations, dust and humidity in the process of transportation, adapt to the 7X24 working model in various environments, and pass the standard testing by the Ministry of Public Security. On the basis of two core technologies including video digest compression & integration and video content retrieval & comparison, and in combination with the case-handling equipment as part of the video investigation management procedures, the product can effectively extract the moving objects in the original video and reduce the time needed to retrieve the original video. This, coupled with the function of video content retrieval, is helpful to identify suspicious objects quickly and extract relevant clips with annotations.

The spatio-temporal analyzer professional edition, based on the video structuralization algorithm of deep learning, comes as an upgraded version of the standard edition, whether in function or hardware. GPU processor is added to raise the efficiency and accuracy in handling the video, realize an extraction of the moving objects in the video followed with a structuralized analysis of the relevant person, vehicle and things, and rapidly obtain the valuable information in the video through such means as reverse image search and structuralized feature search.

As a product aimed to collect a large amount of information including the monitoring point in a rapid way by using the intelligent police terminal, the monitoring point information acquisition system is characterized by functions like data acquisition, real-time synchronization, local export and automatic annotation, which facilitates the management and control of society-wide monitoring information by investigators.

The mobile video command system relies on the mobile network to realize a real-time presentation of information such as audio and video data, instant communication information and location information produced by the personnel and device, and visualized command/scheduling with highly-efficient interactions between the front and back stage. It has such functions as information release, multi-source map, personnel scheduling, real-time trace and remote command.

The product is composed of the full-frame prospecting instrument and on-site environmental information reconstruction equipment for individual police. With data from multi-source maps including the panoramic view, orthographic projection, 3D map and planimetric map, it features intelligent annotations of multi-dimensional information on the map, such as text, free-hand drawing, material evidence of trace, and clues, resulting in an all-dimensional reconstruction and visualized display of the crime scene.

The product is made up of the front-end camera, transmitting/receiving equipment, ground station and intelligent analysis terminal device. Supported by microwave and 4G transmission, the product receives and transmits mobile videos and video surveillance images in wireless mode, resulting in a rapid deployment and intelligent control of the suspicious object.

During the formation of images for video surveillance equipment, problems including failure to effectively extract key information about the object in the video image and image blur caused by the reduced video image quality may exist. To tackle such problems, the police image processing system combines the collection, processing, analysis and materialized management of images into an integral whole, and thus emerges as a professional tool for processing videos, sequential images, single image and special objects (human face, and vehicle type and plate number). On this basis, the system provides strong support for video investigation users in terms of comprehensive image analysis and materialized processing.

The video image information management system serves as a product used for uniform storage and application management of the videos, pictures, and the suspicious person and vehicle concerned in investigating and coping with a case. The system supports an associated comparison of various connected cases, i.e. means are available for a detailed comparison of identical and similar cases, in order to facilitate the handling of both major and small cases. Through the system, problems including complicated storage operations in traditional mobile hard disk and optical disk, great difficulty in looking up data and failure of rapid application in the later period are solved.

The police unmanned aerial vehicle is known for a combination of functions like image collection, 3D modeling and tracking and control of objects. The equipment applies to on-site investigation, high-altitude investigation and large-scale security activities. It is useful in realizing the effect of stereoscopic investigation and visualized command in the on-site environmental information reconstruction system and mobile video command system.

The video big data combat application platform, a product especially designed for crime investigation users and applicable to a wide range of application platforms, can provide applications such as structuralized analysis of massive videos, cleaning and gathering of sensory data, GIS-based visualized search of resources, deduction and analysis of data relationship, and search for and control of key objects, aside from step-by-step big data analysis service support for the early-warning, prevention and control. Besides, the product has the ability to realize a deep integration between the police investigation system resources and procedures. This fills the gap left by the traditional video investigation platform, with the emergence of a new model for the video investigation combat application platform.

The video detection car is a special type of vehicle specially designed for use in mobile case investigation and solving. When it comes to investigating the case in practice, the video investigation car can play its role on the site, which brings an on-site command during the investigation process through a motorized tool. The vehicle-mounted equipment and system offer convenience to on-site environmental investigation, evidence collection, acquisition of all sorts of information, mobile control, video processing, investigation, study and judgment of a case, command and decision-making, among other work in the case investigation.
