Automatically follow the explanation of high-speed ball

Automatic track ball machine introduction

●Features:

When the moving target enters the camera's field of view, a high-speed DSP chip is used to perform differential calculations on the previous frame of the image and the current image. When a certain value is reached, a specific part of a frame is determined as a moving object, and then The ball machine automatically issues instructions to the ball head, so that it cycles back and forth, thus controlling the ball camera to achieve continuous tracking of moving objects without the need for human operations, and does not require the support of computer systems!

●Features:

Has a tracking function for capturing moving targets in a complex background. That is, there is no need to add any hardware or software. As long as the moving target is in the field of view, the dome camera can automatically capture and track the moving target, realizing 24-hour unattended security on duty! Support the alarm to find the point and start the tracking: The track ball and the alarm device can be connected through the 485 control line. Once an alarm signal appears, the track ball will automatically shift to the specified position and then start the tracking.

The technique of automatically returning a preset point: that is, after the ball camera finishes the whole process of tracking (tracking is completed after the target leaves the field of view of the camera), it can return to the point where the tracking started within the user's specified time!

With multi-point preset positioning, memory, auto cruise, curve trace scan, local scan (90° or 180° or 360°) and other functions. You can arbitrarily position, but also omni-preset cruise!

Explanation of automatic tracking dome camera

1. Automatic Tracking Dome Camera

The AutoTrack dome camera (AutoDome) is a new type of camera that can be programmed to perform "smart patrols" by scanning an area according to a pre-programmed patrol route. When a motion is detected, the camera will stop performing. The patrol program zooms in on the target image and tracks the target in order to record the motion and send an alarm. These actions do not require the help of the operator, allowing the operator to handle the alarm or take other actions.

2. Automatic tracking of dome cameras will improve the detection performance of security systems

2.1 Detection is the core of security technology

Security technology is a comprehensive application of detection and control of related technologies. When it draws on related technologies for application development, it always focuses on detecting this core. Detection is also the basic function of the security system.

The advantages and disadvantages of the detection and alarm system performance, such as false alarm rate, missed report rate, zone detection sensitivity, detection range and so on, mainly depend on the detection performance of the detector.

At present, the detection equipment used in the detection and alarm system is mainly to detect changes in the physical quantity and status of the environment. This detection method does not inherently have the ability to detect targets. Therefore, the problem of false alarms has plagued security systems. The use of multiple detector elements, multi-technical composite detection, and intelligent data analysis has greatly improved the performance and functionality of the detector and reduced the false alarm rate. However, this does not fundamentally solve the problem.

The video surveillance technology observes the on-site objectives and directly identifies the features of the target. This is an effective detection method and is a detection method that does not require rechecking or integration with the review.

In the design of real security projects, we must first consider the alarm, the so-called alarm priority, and the video surveillance as an auxiliary system, because any check-in operator in an unknown state, can not pay attention to the picture for a long time. In order to reduce the influence of artificial fatigue factors and ensure reliable operation of the system, alarms are usually given priority.

2.2 Automatic tracking of dome camera detection of moving targets

The dome-type camera featuring automatic tracking is known as the "tracking technology for liberating manpower movements." The monitoring system using this camera can intelligently detect and track moving targets and achieve automatic tracking, recording and alarming of moving targets. Completely changed the video surveillance system can only be used as an auxiliary system situation.

2.3 The difference between automatic tracking ball camera and video motion detection technology

(1) Automatically tracked dome cameras can be programmed to perform “smart patrols” and scan an area in accordance with a pre-programmed patrol route. Once a motion is detected in any position within the entire scan area, automatic tracking and recording are immediately implemented. Call the police. The motion detection that video motion detection technology can do is limited to the inherent field of view of the camera. When the video recorder receives the motion detection sensor signal and then starts the video recording, when it is recorded in a fixed period of time, it will be ignored. Whether the moving body is still in the field of view of the camera.

(2) The auto tracking ball camera can set the size of the target to be tracked through the motion detection algorithm, so that any target smaller than the set size, such as birds, animals, or other objects will not be tracked. This is difficult to do with video motion detection.

3. Automatic Tracking Dome Camera Improves Monitoring Performance of Security Technology

3.1 The monitoring system using automatic tracking ball cameras will be active monitoring

Most monitoring systems are reactive. The method used by this monitoring system is to view videotapes or hard drives afterwards and to study what happened at the time. It is a passive monitoring method. For automatically tracking ball cameras, when a motion is detected, the camera sends out a signal to instruct the camera to actively track the target. At the same time, the recording frequency of the video is increased and an alarm is issued to the operator. After the intruder is locked, the operator is automatically tracked. It is an active monitoring method to immediately study the images that enter the scene and take action to stop the crime.

3.2 The operator's work becomes easier and more efficient

Under normal circumstances, an operator needs to monitor multiple screens and control the camera's joystick. After an automatic tracking ball camera, the camera monitors itself and once it detects motion, it automatically completes zooming, tracking, recording, and alarming. , so that the operator does not need to stare at the screen to complete other tasks.
