Building advanced CCTV security systems: Control room components

October 1, 2009

Recording and Management Servers
Within the primary control room, there will be servers with sufficient storage to capture video at full frame rate DVD resolution from the cameras located around the site.

In addition to the recording servers, the primary management server will also reside within this location.  The management server stores all user and system configurations and enables the management of devices and alarms. Each of these servers will be protected from power loss by the inclusion of UPS battery backup devices.

Viewing and Replay
Each Operator workstations has dual 19” LCD displays and a Joystick for PTZ camera control.  These workstations will be powered by the Cware Control Centre application that enables the operators to view live or recorded video, manage alarms and control cameras.

The Control Centre user interface is designed to be as simple as possible while still providing advanced capabilities.  The main screen can be utilised as the operator’s spot monitor and facilitates viewing of multiple cameras in live or replay mode, export of footage, viewing of alarms, management of the video wall and so on.  To enable simple navigation through the cameras and provide vital information on camera positions, the second monitor can be used as the map interface.  The map interface can provide users with a zoom overview of the site and highlight elements such as alarm triggers and camera positions.

As well as the maps, the system can be licensed with the patented ICN feature.  ICN stands for Image Content Navigation and enables a revolutionary method of navigating through the system.  With ICN enabled, it is possible to setup predefined invisible links within the video image from a camera that link to another camera.  This offers the operator the opportunity to click on an area of the image and the system will automatically switch to the best view of that area.  For example, if you have a camera overlooking a doorway and you see a suspicious individual enter through the door of a building, ICN makes it possible to click on the door and automatically switch to the camera inside quickly and easily without having to search through a list of cameras to identify the correct one.

The Cware server within the central location will constantly monitor each remote IP camera and encoder (for existing analogue cameras) device for alarm triggers, such as motion detection.  In the event of an alarm trigger from a remote location, the alarm management and response configuration can allow for a variety of notification methods, including simply presenting the user automatically with the video on their spot monitor or presenting the alarm to the video wall displays.

In addition to the monitoring motion alarms, the system can also enable system health monitoring.  In the event of events such as loss of connectivity to a server or the failure of a video feed to an encoder, an e-mail can be sent out to system administrators who are responsible for maintenance and upkeep.  This ensures that the system can proactively prevent and notify of potential performance issues.

The system also provides comprehensive logging, including operator activity, alarms and so on.  The log viewer tool then enables system managers to search and extract valuable information as a CSV file. This can then be imported into 3rd party systems, such as excel, to assess performance such as response times, number of alarms and so on.

Videowall
Within the control room, there will be high performance rack mount workstations connected to a large screen LCD displays.  These workstations will be powered by the Cware Videowall application.  Each workstation can display up to 16 or more video streams from remote cameras on wither a predefined or custom layout.  The Control Centre clients can manage the display of the cameras onto the video wall by simply clicking a tab at the bottom of the screen and choosing which cameras they would like to display.  It is proposed to utilise one or more of the screens as a dedicated alarm display whereby all incoming alarms from cameras can be shown to highlight this to the user.

IP CCTV or analogue CCTV, which is best?

July 27, 2009

Info4security.com open a new dabate about the best technology to use for CCTV security.

Analogue CCTV has been around for a very long time, is expensive to maintain and difficult to integrate. IP based systems on the other hand deliver improved control of video data and integration with Access Control, Intruder and other external systems.

Is it now time to replace this technology and move to IP based CCTV?

What are the benefits of IP CCTV?

What are the challenges involved with moving to an IP based CCTV system?

How much will it cost?

Find out the answer to all these questions and post what you think here at the info4security discussion page.


IP CCTV can deliver huge benefits over analogue systems

June 24, 2009

Here are some reasons why….

Improved video quality
IP CCTV solutions support far greater image quality through Megapixel and High Density (HD) technologies that deliver higher frame rates. This enables CCTV to be of high enough quality to clearly capture an incident in progress and therefore identify the persons involved and if necessary bring in law enforcement agencies in order to prosecute with confidence.

Future Proofing
By deploying an IP CCTV solution future proofing can be achieved by enabling integration and support for new technologies and applications such as H.264, HD, Megapixel cameras, proximity access control and identification, Video Analytics, Facial Recognition and Automatic Number Plate Recognition (ANPR). Integration with these technologies enables CCTV to be extended to provide an additional level of security for traffic monitoring, parking, and access control applications.

Linking CCTV with Access Control technology can deliver real benefits. For example in a school a single card could be used for students and staff for access to secure areas, library card identification, time and attendance records and cashless vending. CCTV images can be linked to Access Control records so that in the event of crimes such as vandalism, pilfering or identity theft rather than simply having a database you have a visual image to quickly identify if the access records are correct and also avoid any rebuttal from potential suspects.

Secure access remote access enables an IP based solution to be monitored from anywhere not just in a central control room. Using the integrated intelligence of IP based solutions automated audio response and alarm escalation out of hours can also be achieved as well as incorporation of help points and streaming video to mobile phones.

Cost savings
• IP based surveillance typically has a lower total cost of ownership than traditional CCTV due to the application of recent technological advances.

• CAT 5 structured cabling reduces installation costs.

• Taking advantage of PoE technology means fewer cables need to be run to cameras than traditional cabling and resilience can be increased through the use of Uninterruptable Power Supplies (UPS).

• Latest recording compression standards such as H.264 also provide a saving of up to 75% capacity over traditional analogue solutions whilst maintaining high quality video recordings.
