Physical Security

DVI Communications has been a leader in the deployment of physical security systems for government, transportation, and financial services entities.  We will help you:

  • Deploy the latest security monitoring technologies
  • Improve responsiveness and situational awareness
  • Enhance privacy and reduce leakage
  • Eliminate or greatly reduce “blind spaces” by improving in-building communication (e.g., repeaters, gateways)
  • Deploy & test Public safety systems and dispatch (e.g., ruggedized systems)
  • Take control of all your corporate, transportation, and institutional security
  • Reduce risk while at the same time installing cost-effective solutions
  • Meet regulatory directives

We can assist you in all aspects of system implementation, from requirements collection and specification development, to technology selection, multi-vendor integration, deployment, and administration. 

SAVE® (Security Assessment Validation & Engineering), DVI’s comprehensive security consulting service, is based on the philosophy that in order to “harden the target” and make a facility more impervious to attack, it is necessary to base the security conceptual design on four key elements to thwart the wide range of threats to personnel, equipment, and the facility, as follows:

  • Prudent use of advanced technology including integrated, IP based CCTV, access control, perimeter protection, recording, biometrics etc.
  • The utilization of physical barriers, bollards, electronic security systems, magnetometers, mail scanners, protective window films, ballistic partitions, gas sensors, and air filtration systems to protect both the perimeters and the interiors of the facility;
  • Use of Crime Prevention Through Environmental Design (CPTED) principles to create a facility that is resistant to a physical attack;
  • Use of well-trained security personnel for lobby screening of all employees and visitors, and to protect the perimeter of the facility (armed where and if needed); and,
  • Development of written security policies and procedures to cope with the current range of threats.

This philosophy is what comprises the Unified Security Perspective, today’s proactive response to the broad range of security risks and the threat of national an international terrorism confronting organizations.  Working with our clients, DVI helps to define the level of protection that is needed for people and for equipment.  We weigh effectiveness against ease-of-use, and consider life-cycle costs and total cost of ownership.  We’ll help to define client contingency requirements, and then arrive at a thoroughly detailed plan that blends proven practices with the most reliable advances in security technologies. 

DVI is expert in the latest state-of-the-art in Video Surveillance Technology, Access Control, Intruder Detection and Telecommunications technologies.  This encompasses:

  • Camera Technology: Digital IP, high resolution, color cameras offer improved viewing under variable lighting conditions in conjunction with traditional pan/tilt/zoom controls; camera lenses and electronics placed in specialty enclosures (e.g. sacrificial glass), can operate in all-weather/temperature conditions, are vandal-resistant and suitable for indoor/outdoor applications.
  • Video Recording: Digital video recording using advanced video compression technology (e.g., Motion JPEG, MPEG II or H.264) can store months’ worth of full motion video archives. Depending on system requirements storage can be DVR, NVR or mass storage array based or tiered mixes of these devices. In addition, video compression can be utilized to accommodate multiple high – resolution streaming video sources delivered over modest bandwidth facilities to achieve cost savings.
  • FO & wireless Distribution Networks: Fiber optic distribution can deliver high quality signals many miles for remote as well as local viewing and recording operations.  Existing fiber optic network infrastructure in conjunction with LANs can be leveraged to offer centralized, regional and local monitoring. Wireless Backhaul networks can support multiple applications (Including video surveillance) to accommodate deployment of cameras in locations that cannot easily be served by wireline distribution.
  • Advanced Image Processing: Both real-time and stored digitized video can be subject to advanced image processing that goes far beyond simple applications such as motion detection.  Some of the advanced applications that are possible are:
      • Digital Image Enhancement can clarify images and extract views of objects that may be shadowed;
      • Criteria can be established to define events which should be recorded and/or alerted to monitoring personnel;
      • Aberrant Behavior Detection Software can be programmed to monitor and detect “unusual” behavior
      • Customized graphical User Interface: This digital video processing technology, coupled with advanced/customized graphical user interfaces are used to allow hundreds of camera inputs to be displayed on dozens of screens in a more “intelligent” manner.   The simplistic notion of “fixed vs. variable views” is thus augmented to determine cameras/views of interest based upon event triggers.
      • Video over IP:  Video over IP distribution technology using IP-addressable cameras also allows more graceful system expansion and greatly simplifies the support of local/remote viewing and recording options as well as multipoint broadcast distribution.
      • Integrated CCTV/Access Control Security System: Video Security Systems integrated with card access and biometric access control, panic/duress alarms, 1-/2-way emergency intercoms and building/facility management systems can support the development of a sophisticated security infrastructure.
      • Use of 2-Way Audio (in conjunction with Video): The effective use of two-way audio communications can be integrated with the Video Surveillance system (talkback/speakers). For example, a verbal warning could be issued via an open speaker/microphone, or used to question an individual who may have fallen on the stairs in order to assess their physical condition.

DVI also can address Networking Impacts taking into account:

  • Centralized vs. Regional/Centralized Monitoring Schemes
  • Recording Backup
  • Selective use of Wireless Distribution and backhaul
  • Interoperability with other systems (e.g. Access Control, Intruder Alert, PDA’s)

As well as ancillary considerations necessary for a complete working system:

  • Lighting
  • Inventory/Logistics/Maintenance/Backup/Requirements
  • Vandal -Resistance
  • Expandability
