Ⅰ. Introduction

The rapid development of security industry calls for the need of a more intelligent video monitoring. For the reason The rapid development of security industry calls for the need of a more intelligent video monitoring. For the reason that a massive amount of video is being recorded, but hardly ever being reviewed, it is ordinary to miss suspicious behaviors. To avoid such events and activities being missed, Milesight propounds intelligent Milesight Video Content Analysis(VCA). Embedded in network cameras, Milesight now has a complete VCA Solution, realizing 8 VCA functions via Network Cameras, NVR and CMS.

Ⅱ. What is Video Content Analysis?

Video Content Analysis(VCA), also referred to Intelligent Video Analysis (IVA), is the capability of automatically analyzing video to detect and determine temporal and spatial events. The algorithms can be implemented as software on general purpose machines or as hardware in specialized video processing units. It automatically performs an analysis of captured video, and automatically uses the resultant data. This technical capability is used in a wide range of fields including entertainment, health-care, retail, automotive, transport, home automation, safety and security.

Ⅲ. Milesight Video Content Analysis

Milesight VCA provides advanced video analysis for Milesight network cameras, NVR and CMS. It enhances the performance of network cameras through 10 detection modes, enabling the comprehensive surveillance function and quicker response of the whole VCA solution to different monitoring scenes. In addition, Milesight Network Cameras, NVR and CMS all support independent function settings for convenient user experience. The Milesight VCA solution ensures that video surveillance is more accurate and cost-effective.

· Region Entrance

1. What is Region Entrance

Region entrance helps to protect a special area from potential threat of suspicious person’s or object’s entrance. An alarm will be triggered when objects enter the selected regions by enabling region entrance.

Figure 4-1  Region Entrance

If you enable Detection Object(Human/Vehicle), the selected regions will display in“red”when the alarm is triggered.

Figure 4-2  Region Entrance Trigger

2. How to set Region Entrance with Milesight Network Cameras

Step1: Enable region entrance detection and draw a region by clicking the mouse. Any object entering into the region will trigger an alarm. The “Object Size” can be set to define whether an object is big enough for triggering the alarm when enter into the selected region.

Figure 4-3  Region Entrance

Step2:Set detecting sensitivity and object size limits. The “Object Size” can be set to define whether an object is big enough for triggering the alarm when enter into the selected region.

Step 3: Set entrance detection region;

Step4: Set detection schedule, you can set the schedule by checking “Edit” button. And then click [Save] or [Reset] after all done. You can also copy the settings to other channels.

· Line Crossing

1. What is Line Crossing

Milesight line crossing detection is designed to work in most indoor and outdoor environment. An event will be triggered every time when the camera detects objects crossing a defined virtual line. It is especially suitable for general monitoring of entrance and exit points in low-traffic areas, detecting objects such as people and vehicles that cross the defined virtual line.

Figure 4-16 Line Crossing

2.How to set Line Crossing

Enable line crossing detection. Click the mouse to draw a line in the monitoring view. Milesight allows to set up to four lines at a time. There are three direction modes to choose for triggering alarm. “A→B” means when there is any object crossing the line from the “A” side to the “B” side, the alarm will be triggered. “B→A” vice versa. “A←→B” means that the alarm will be triggered when objects cross line from either side.

Figure 4-17 Line Crossing Settings page

· Loitering

1.What is Loitering

When objects are loitering in a defined area for a specific period of time, it would trigger an alarm. Illegal activities towards the places like retail stores and banks would be nipped in the bud thanks to this function.

Figure 4-18 Loitering

2.How to set Loitering

Enable loitering detection and draw an area in the view. After setting minimum loitering time from 3s to 1800s, any object loiters in the selected area over the minimum loitering time will trigger the alarm. Also Milesight loitering allows to set “Object Size”. Only the object bigger than the set size will trigger the alarm.

· Object Removed

1. What is Object Removed

Object Removed is used to secure objects’ safety. When there is an object removed from a pre-defined region, it will detect and prompt an alarm. You can set the maximum 4 object left regions, the sensitivity and object size limits can be set in the “General Settings”.

Figure 4-22 Object Removed

2. How to set Object Removed

Enable object removed detection and set minimum time, then draw a region by clicking the mouse. Any object removed in the region over the minimum time will trigger an alarm.
