S5.2 IR - a robot with a thermal imaging CCTV system

Main pageProducts

The security robot features a dual-spectrum PTZ camera with heat and visible radiation sensors.

Thanks to these sensors, the onboard video analytics system can recognize people and machines from a distance of up to several hundred meters away, in total darkness.

 

In a surveillance position, the robot scans its surroundings by rotating the PTZ camera. When the onboard video analytics system detects a person or a machine, the PTZ camera starts tracking these objects. Video content and alarm signals are transmitted to the CCTV surveillance center through 4G or Wi-Fi networks. When zooming in on an image with the PTZ camera, a high level of detail is still maintained while keeping low traffic over the channel.

 

The S5.2 robots can autonomously patrol the guarded premises, following pre-programmed routes without any human intervention. These robots can either be integrated into existing stationary CCTV systems or work autonomously, and report suspicious activity by sending the relevant information to supervisors’ smartphones.

All S5.2 security robot models possess the following functional features

  • Autonomous movement along the programmed routes
  • The ability for a group of robots to patrol the premises
  • Transmitting ONVIF video and reporting suspicious activity through 4G or Wi-Fi networks
  • Video surveillance and notifications delivered through CMS or a smartphone
  • Voice Notifications and an IP intercom communication system to reach out to the operator
  • Automatic charging

The intelligent infrared CCTV system has the following features and components

  • A dual-spectrum PTZ camera
  • Detecting and tracking thermal anomalies
  • Human recognition and tracking with the PTZ camera
  • A CCTV system with six 360-degree cameras
  • Panoramic cameras for human detection and facial recognition

  • A highly efficient antenna system

NIGHTTIME VIDEO SURVEILLANCE WITH A THERMAL IMAGING CAMERA

Thermal Imaging Camera for Nighttime Video Surveillance and patrolling

The CCTV system installed in the security robots includes a PTZ camera with two sensors, one for detecting heat and the other for visible radiation. Thermal imaging allows tracking people and machines from a distance of up to several hundred meters away, in complete darkness. These robot models are equipped with a built-in supercomputer to process video received from both sensors installed in the PTZ camera, as well as to control the camera.

 

In surveillance mode, the PTZ camera continuously scans its surroundings by revolving around its axis. Whenever the camera detects people, machines, or other thermal anomalies, it starts tracking those objects. Video analytics tools employed in the thermal imaging channel can detect a thermal anomaly even if the object is far away. At the same time, a program for processing images received from the visible radiation sensor performs a search for humans, detects them, and captures their faces, provided there is enough ambient light. When there isn't enough light, the tracking system uses the information received from the thermal imaging camera.

Integrating Mobile Security Robots into a Stationary CCTV System

A robot’s CCTV system can be easily integrated into the ONVIF CMS. This allows the operator to watch video footage received from both of the PTZ channels, as well as the six panoramic cameras. The operator can turn off the automatic PTZ camera control system and switch over to manual control mode.

 

The image received from the PTZ cameras has television-level resolution, and a sufficient level of detail is achieved with the help of an optical zoom. At the same time, the flow of data arriving from these cameras is not large, which allows the reliable transmission of video footage through wireless communication channels.

 

Along with the video streams coming from the robot's camera, the CMS operator receives data about the robot's current location on the facility's map in two scales. Maps are transmitted in the form of video that does not require any software enhancements in the CMS.

Two Nighttime Patrolling Robot Models

Both security robot models in this series are equipped with six 360-degree panoramic CCTV cameras. These cameras allow continuous monitoring of the parts of the facility that are in close proximity to the robot. This kind of solution completely prevents humans from approaching the robot unnoticed, since the PTZ cameras work in all directions.

 

In closed premises, where there is no high risk of the robots being impacted by external forces, panoramic cameras do not have to be equipped with instruments to detect human beings; in this case, they transmit videos only upon the operator's request. For areas where unauthorized people may approach the robot, a model was created that can detect people standing within the panoramic cameras’ field of view. In this situation, the operator will receive an alarm signal and a video whenever a person standing close to the robot is detected. If nobody is near the robot, the videos received from all the panoramic cameras are sequentially displayed along a single alarm channel.

Human Detection and Facial Recognition with Panoramic Cameras

S5.2 IR IS security robots are equipped with panoramic cameras that have analytics instruments installed. These tools can capture the face of a person standing in close proximity to the robot. This feature makes it possible for security officers to control the process of patrolling the premises and reduce the number of suspicious activity alerts received by the operator. Face recognition takes place in the cloud.

High-Efficiency Wireless CCTV Antenna

Scanning PTZ cameras can monitor large territories. In these scenarios, the security robots’ performance depends entirely on how reliable the wireless communication channel is. In order to make the channels more stable, each robot in the S5.2 series was equipped with an omnidirectional antenna located at the top of the robot's mast. This efficient antenna allows establishing connections between robots through a Mesh Wi-Fi or a stable broadband 4G network.
