Virtual Sentry is a state of the art, scalable, software and hardware solution that seamlessly integrates various technologies and applications to provide an automated, real time, event-based remote video monitoring solution for outdoor applications. Visentry’s concept is designed to effectively monitor remotely multiple sites.


Virtual Sentry is implemented across three main segments:

-- A. Remote site (customer’s location)

-- B. IP networks

-- C. Visentry Central Monitoring Station (CMS)


A. Remote site
The remote site system includes the following parts:

1. Virtual Sentry Control Center – VIS-150
This product is the heart of the system and was designed by Visentry with the purpose to centralize all control function and allow for simple and low cost installation. The main functions of the VIS-150 are:

-- Management of alarm signals
-- Management of video (compression, transmission) signals
-- Management of audio signals
-- Transmission of video, audio and data signals via the internet to the CMS

2. Video system
The video system includes the video cameras that form the virtual perimeter around the site. They are Day/Night cameras that provide good quality images at night with very low level of illumination. We are also utilizing several PTZ (pan, tilt, zoom) cameras for investigative purpose once the alarm is triggered. They enable our security agents to follow suspects, zoom in for closer shots and cover areas inside or outside the perimeter as needed.

3. Audio system
The audio system includes several sets of loudspeakers and microphones strategically located to provide our agents the ability to listen in or to speak to any portion of the site with clarity.

4. Detection system
The detection system connects to the video camera feeds and continuously analyzes the video streams in real time to detect threats as defined in the site configuration. When a threat is detected the system sends via the VIS-150 a short video clip to the central station which in conjunction with the alarm notification from the VIS-150 begins the investigative process of the alarm at the CMS.

5. Recording system
We are recording all cameras continuously in order to provide more information for investigative purposes after the event has concluded.

B. IP Networks:
The communication infrastructure between the remote sites and the CMS is based on IP links. Virtual Sentry’s communication infrastructure provides:


• Bandwidth Management – ensures that interactive video applications do not saturate the network
• Quality of Service – provides the best video and audio quality at a given data rate
• Reliability and Backup – the VIS-150 detects network failure and switches the transmission automatically from fixed IP to wireless links

C. Central Monitoring Station (CMS):

The Central Monitoring Station (CMS) application allows the creation of a scalable video central monitoring station, capable of monitoring in real time a large number of remote sites. This is achieved through a video event queue, interactive mapping features, pop-up dispatch instructions, easy image capture and e-mail capabilities.


The CMS includes three modules:


Control Module – Allows the CMS operator to control, manage, monitor and record live events at remote sites. Using this module, the CMS Operator is able to initiate connection to any VIS-150 and receive real time live streaming video up to 30 frame seconds. The CMS operator is also able to initiate a connection with any site, or respond to any connection request from any site. Finally, the CMS operator is also able to activate a digital output in any VIS-150, which could be used, for example for remote door locking/unlocking at the remote sites. This module enables CMS agents to effectively review multiple live simultaneous video alarm events received from multiple sites.

VIQ Monitor - The VIQ Monitor enables the CMS agents to receive and review alarm clips from the Intelligent Detection Unit. This enables them to make an immediate determination if the alarm is true or false.

Monitoring Automation Module – This module includes all functions related to alarm management, multi-site operation, multi-agent operation, archiving of video and data and manages customer information. This module includes databases with customer information that are automatically linked to the site ID received during an alarm and populates the agent’s screen with the information required to process the alarm. This module allows for the creation and archiving of event video clips which are stored at Visentry. These clips are sent to the customer in e-mail that notifies the customer about the event.


Functional Description
1. Once an alarm is generated by the detection system at the remote site, real time automatic connection is established with the CMS application.
2. The signal received (video, audio and data) is displayed on the agent’s control and mapping monitors, enabling the operator to take full control of the site.
3. In case of multiple alarms, the alarm events will roll over to the next available agent’s control module.
4. The operator has multiple options of action:
• Send the alarm video to multiple security personnel (wire or wireless),
• Create real time two-way video/audio connection with the remote site or other security personnel.
• Control PTZ (Pan Tilt Zoom) cameras and view multiple cameras on a split screen.
• E-mail information (including video snapshots).
• Create video clips of the alarm event.
