In the 21st century, technology has firmly established itself in various fields, including security surveillance systems, which have exceeded our expectations. It's widely recognized that these systems are primarily designed to enhance security. Additionally, some PTZ cameras feature auto-tracking capabilities; however, many people remain unaware of their advanced functions. This article will provide a brief introduction to two lesser-known capabilities: person detection and auto-tracking.
The security camera now offers various detection modes, which determine the motion events that will activate detection and be recorded. In this article, we will focus on the differences between two specific modes and the benefits each provides.
What is a person's detection?
The definition is relatively straightforward; it can be viewed as a system that identifies human presence, which is somewhat accurate. However, this does not fully capture the technical explanation. Let me clarify: it utilizes computer vision technology to recognize individuals within the camera's field of view. With this feature, you can customize your video and alert settings to choose whether to receive notifications for all motion—such, such as people only—or to have them filtered out.
After understanding what person detection is, let's explore some of its key benefits.
  1. Minimizes Frequent False Alarms
Unlike traditional motion detectors that are easily triggered by any moving object—making them unreliable, especially for outdoor surveillance—person detectors offer significantly improved accuracy. This advancement greatly reduces false alarms, helping to maintain trust in the system.
  1. It is simple to access video clips that feature only people’s activities during playback.
By enabling the person detection feature, you can easily identify the locations of video clips that contain only individual activities. A convenient indicator is provided in the playback, helping you save considerable time when searching through extensive video footage for security verification or fact-checking.
What is Auto tracking? (Motion tracking)
Before diving into motion tracking, it's important to understand that it blends both motion detection and auto-tracking technologies. So, what exactly is motion auto-tracking? In essence, it follows moving objects, but that's just a basic overview. To explore this further, it is essential to note that mobility is a key aspect of the motion tracking function. With its motorized joints and advanced programming, the motion tracking system not only identifies when an object enters its field of view but also tracks it as it moves within that area.
As you are now familiar with motion tracking, here are some of the benefits it offers.
  1. Ensure robust security in low-traffic areas.
This system enhances your security and allows for customizable configurations. Similar to receiving a text message alert, it will notify you if motion is detected in designated restricted zones. Consequently, you will receive alerts whenever the cameras sense movement.
  1. Reduces the necessity for manual intervention, thereby minimizing operator distraction.
In contrast to conventional manual tracking, which requires operators to identify and click on monitoring targets, the advanced motion auto-tracking feature eliminates the need for constant operator focus. This allows the camera to automatically track and record the target on its own, enhancing convenience.
  1. Convenient to monitor potential targets in a large area with high quality images.
Additionally, even if the target is far away from the monitoring camera, the high quality image still can be retained with 20x or 30x or higher zoom technology. This makes it have a wider range of applications, like the main user would be the military, and then come sports and entertainment etc.
  1. Reduce the number of cameras needed.
This is due to the capability of motion tracking to automatically follow moving objects and cover a broad monitoring area by utilizing the pan-tilt-zoom feature. Consequently, there is no requirement to position cameras at regular intervals for comprehensive surveillance.
  1. Require less time to search for videos to obtain valuable information.
You can customize the system to record only when movement is detected, which helps minimize the time needed to review footage, as recordings will only include periods when events occur.
