5.8 Setting IVS

This section introduces scene selection requirements, rule configuration, and global configuration for IVS (intelligent video surveillance).

Basic requirements on scene selection are as follows.

- The target should occupy no more than 10% of the whole image.

- The target size in the image should be no more than 10×10 pixels. The size of abandoned object in the image should be no less than 15×15 pixels (CIF image). The target height and width should no more less than a third of the image height and width. The recommended target height is 10% of the image height.

- The brightness difference of the target and the background should be no less than 10 gray levels.

- The target should be continuously present in the image for no less than two seconds, and the moving distance of the target should be larger than its width and no less than 15 pixels (CIF image) at the same time.

- Reduce the complexity of surveillance scene as much as you can. Intelligent analysis functions are not recommended to be used in scene with dense targets and frequent illumination change.

- Avoid areas such as glass, reflective ground, water surface, and areas interfered by branch, shadow and mosquito. Avoid backlight scene and direct light.

5.8.1 Global Configuration

Set global rules for IVS, including anti-disturb, depth of field calibration, and valid motion parameter for targets.

Calibration Purpose

Determine corresponding relationship between 2D image captured by the camera and 3D actual object according to one horizontal ruler and three vertical rulers calibrated by the user and the corresponding actual distance.

Applicable Scene

- Medium or distant view with installation height of more than three meters. Scenes with parallel view or ceiling-mounted are not supported.

• Calibrate horizontal plane, not vertical walls or sloping surfaces.

- This function is not applicable to scenes with distorted view, such as the distorted views captured by super wide-angle or fisheye camera.

Notes

- Calibration Drawing

◇ Calibration area: The calibration area drawn should be on one horizontal plane.

- Vertical ruler: The bottom of three vertical rulers should be on the same horizontal plane. Select three reference objects with fixed height in triangular distribution as vertical rulers, such as vehicle parked at roadside or road lamp poles. Arrange three persons to draw at each of the three positions in the monitoring scene.

◇ Horizontal ruler: Select reference object with known length on the ground, such as sign on the road, or use a tape to measure the actual length.

• Calibration Verification

After setting the ruler, draw a straight line on the image, check the estimated value of the straight line, and then compare this value with the value measured in the actual scene to verify calibration accuracy. In case of major difference between the estimated value and the actual one, fine-tune or reset parameters until the error requirement is met.

5.8.2 Rule Configuration

Set rules for IVS, including cross fence detection, tripwire, intrusion, abandoned object, moving object, fast moving, parking detection, crowd gathering, and loitering detection.

For the functions and applications of the rules, see Table 5-6.

Table 5-6 Description of IVS functions

RuleDescriptionApplicable Scene
TripwireWhen the target crosses tripwire from the defined motion direction, the system performs alarm linkages.Scenes with sparse targets and no occlusion among targets, such as the perimeter protection of unattended area.
IntrusionWhen the target enters, leaves, or appears in the detection area, the system performs alarm linkages.
Abandoned objectWhen an object is abandoned in the detection area over the set time, the system performs alarm linkages.Scenes with sparse targets and without obvious and frequent light change.Simple scene in the detection area is recommended.Missed alarm might increase in the scenes with dense targets, frequent occlusion, and people staying.In scenes with complex foreground and background, false alarm might be triggered for abandoned or missing object.
Missing objectWhen an object is taken out of the detection area over the defined time, the system performs alarm linkages.
Fast movingWhen the motion speed is higher than the configured speed, the system performs alarm linkages.Scene with sparse targets and less occlusion. The camera should be installed right above the monitoring area. The light direction should be vertical to the motion direction.
Parking detectionWhen the target stays over the configured time, the system performs alarm linkages.Road monitoring and traffic management.
Crowd gatheringWhen the crowd gathers or the crowd density is large, the system performs alarm linkages.Scenes with medium or long distance, such as outdoor plaza, government entrance, station entrance and exit. It is not suitable for short-distance view analysis.
Loitering detectionWhen the target loiters over the shortest alarm time, the system performs alarm linkages. After alarm is triggered, if the target stay in the area within the time interval of alarm, then alarm will be triggered again.Scenes such as park and hall.

Cybersecurity Recommendations Apper

Cybersecurity is more than just a buzzword: it's something that pertains to every device that is connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic steps toward protecting and strengthening networks and networked appliances will make them less susceptible to attacks. Below are some tips and recommendations on how to create a more secured security system.

Mandatory actions to be taken for basic equipment network security:

1. Use Strong Passwords

Please refer to the following suggestions to set passwords:

  • The length should not be less than 8 characters;
  • Include at least two types of characters; character types include upper and lower case letters, numbers and symbols;
  • Do not contain the account name or the account name in reverse order;
  • Do not use continuous characters, such as 123, abc, etc.;
  • Do not use overlapped characters, such as 111, aaa, etc.;

2. Update Firmware and Client Software in Time

  • According to the standard procedure in Tech-industry, we recommend to keep your equipment (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped with the latest security patches and fixes. When the equipment is connected to the public network, it is recommended to enable the “auto-check for updates” function to obtain timely information of firmware updates released by the manufacturer.
    • We suggest that you download and use the latest version of client software.

"Nice to have" recommendations to improve your equipment network security:

1. Physical Protection

We suggest that you perform physical protection to equipment, especially storage devices. For example, place the equipment in a special computer room and cabinet, and implement well-done access control permission and key management to prevent unauthorized personnel from carrying out physical contacts such as damaging hardware, unauthorized connection of removable equipment (such as USB flash disk, serial port), etc.

2. Change Passwords Regularly

We suggest that you change passwords regularly to reduce the risk of being guessed or cracked.

3. Set and Update Passwords Reset Information Timely

The equipment supports password reset function. Please set up related information for password reset in time, including the end user's mailbox and password protection questions. If the information changes, please modify it in time. When setting password protection questions, it is suggested not to use those that can be easily guessed.

4. Enable Account Lock

The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked.

5. Change Default HTTP and Other Service Ports

We suggest you to change default HTTP and other service ports into any set of numbers between 1024\~65535, reducing the risk of outsiders being able to guess which ports you are using.

6. Enable HTTPS

We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel.

7. Enable Whitelist

We suggest you to enable whitelist function to prevent everyone, except those with specified IP addresses, from accessing the system. Therefore, please be sure to add your computer's IP address and the accompanying equipment's IP address to the whitelist.

8. MAC Address Binding

We recommend you to bind the IP and MAC address of the gateway to the equipment, thus reducing the risk of ARP spoofing.

9. Assign Accounts and Privileges Reasonably

According to business and management requirements, reasonably add users and assign a minimum set of permissions to them.

10. Disable Unnecessary Services and Choose Secure Modes

If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks.

If necessary, it is highly recommended that you use safe modes, including but not limited to the following services:

  • SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication passwords.
  • SMTP: Choose TLS to access mailbox server.
  • FTP: Choose SFTP, and set up strong passwords.
  • AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.

11. Audio and Video Encrypted Transmission

If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission.

Reminder: encrypted transmission will cause some loss in transmission efficiency.

12. Secure Auditing

  • Check online users: we suggest that you check online users regularly to see if the device is logged in without authorization.
  • Check equipment log: By viewing the logs, you can know the IP addresses that were used to log in to your devices and their key operations.

13. Network Log

Due to the limited storage capacity of the equipment, the stored log is limited. If you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing.

14. Construct a Safe Network Environment

In order to better ensure the safety of equipment and reduce potential cyber risks, we recommend:

- Disable the port mapping function of the router to avoid direct access to the intranet devices from external network.

  • The network should be partitioned and isolated according to the actual network needs. If there are no communication requirements between two sub networks, it is suggested to use VLAN, network GAP and other technologies to partition the network, so as to achieve the network isolation effect.
  • Establish the 802.1x access authentication system to reduce the risk of unauthorized access to private networks.
