Network Cabling & Structured Cabling

Network cabling systems serve as the backbone of a comprehensive communications system. It provides a secure and reliable way to transmit data, information, and communications.

Structured cabling refers to all of the cabling and components, designed and installed in a logical, organized way.

Single-mode, Multi-mode, and Photonic Fibers.

Outside Plant Cabling

OSP stands for Outside Plant Cabling. It refers to cabling infrastructures external to buildings, typically run underground, via conduit systems, or above ground via telephone poles

OSP networks are most commonly used to provide a network connection between two or more separate buildings in a campus environment up to extended connections between communities, cities or even states.

Security & Access Control

The three components of a physical security plan to keep a place secure include access control, surveillance, and ongoing system testing.

These four layers of a physical security system work together to prevent breaches:

  • Deterrence
  • Access Control
  • Detection
  • Identification

  • IP (Internet Protocol) Video Surveillance Camera – Also sometimes referred to as network cameras, IP cameras follow internet protocols to transmit data over a network. This allows video data to be accessed anywhere there is a reliable internet connection.
  • Closed Circuit Television Cameras (CCTV) – Run on a traditional analog system, cameras use a DVR to record video.

A Security Digital Video Recorder (DVR) is a device that is compatible with CCTV cameras and converts video from the camera into a digital format recorded on a hard drive. A Security Network Video Recorder (NVR) is only compatible with IP camera, but functions the same as a DVR.

Yes. Some IP video surveillance cameras offer audio recording capabilities. However, CCTV video surveillance cameras do not offer audio recording as a built in option. You would need to purchase after-market add-ons for audio recording capabilities.

Motion detection is a software feature that detects when pixels in an image change. It alerts the system to begin recording when motion is detected.

  • Physical Access Control Systems
  • Cybersecurity/Digital Security Systems

  • Control Environment
  • Risk Assessment
  • Control Activities
  • Information and Communications Control
  • Monitoring

Audio/Visual

Audio/Visual technology can help improve communication, increase efficiency, upgrade security, and add interest/improve cognitive retention.

DAS: Cellular Distributed Antenna

DAS stands for Distributed Antenna System. It is a network of antennas that sends and receives cellular signals generated by other sources (and typically doesn’t generate it’s own signal) to improve connectivity. A basic DAS has two primary components: a signal source and a distribution system.

The four main types of DAS distributions systems include active, passive, hybrid and digital. The hybrid distribution system is the most common.

Public Safety Radio Systems

Public Safety Radio Systems are wireless communications systems used by first responders to respond to emergency situations and/or prevent situations that may pose a danger. These systems are especially important because they allow first responders to stay in contact during emergency situations when other forms of communication may be down.

Almost every city and county in the United States has some form of local ordinance or building code requirement for in-building first responder communications coverage. For most buildings, coverage must meet all NFP and/or IFC requirements. Plus, for most buildings to get occupancy permits, first responder communications systems will need to meet any additional specific requirements of the local Authority Having Jurisdiction (AHJ) and pass their testing protocols

GPON

GPON is an abbreviation for Gigabit Passive Optical Network. GPON is a point-to-multipoint access network offering a fiber-to-the-home solution. It uses passive splitters in a fiber distribution network to enable providers to serve multiple homes and small businesses via a single feeding fiber.

EPON is an abbreviation for Ethernet Passive Optical Network. Both are optical fiber networks that enable computer network connections over a telecommunications infrastructure. However, GPON provides three Layer 2 networks: ATM (voice), Ethernet (data) and a proprietary encapsulation for voice. EPON only provides one Layer 2 network that uses IP to carry data, voice, and video.

POWER OVER ETHERNET (PoE)

Yes. Cat5e and Cat6 Ethernet cables can carry 10/100/1000 Mbps of data and 15W, 30W, 60W, and up to 90W of power budget to devices for a maximum distance of 100m.

The device that transmits power is a PSE, while the device that is powered is a PD.

PoE devices using the PoE standard 48V 802.3af or 802.3at use active POE, while devices not using the PoE standard use passive PoE.

Standard PoE has Ethernet cable distance restrictions of 100 meters (328 feet) for data and power transmission, whether for IEEE 802.3af (PoE) or 802.3at (PoE+). However, when utilizing high current DC Power distribution, which is safe to the touch, distances up to 1931 meters (1.2 miles) can be achieved.

PoE delivers data AND power over one Cat5e/Cat6 Ethernet cable, making it easier/faster to install and installation is less expensive.

Yes, this is a convenient and cost-effective way to upgrade a system utilizing non-PoE devices already in place. However, as non-PoE devices, they will still require an additional outside power source.

Lighting PoE & Controls

PoE technology is a collection of standards whereby both power and IT protocols are sent over the same standard Ethernet cables. It’s used for lighting setup and controls, thus eliminating the need for separate electrical wires.

Customers who switch to PoE lighting can save up to 33% in energy costs. Plus, proponents of PoE say that the power supply is more reliable. Customers can also see savings on CAPEX and OPEX (by utilizing the IoT capability of the system).

PoE technology eliminates all the high voltage circuit alignment in the ceiling and any associated metal conduits required to run those high voltage wiring. This benefit plus less expensive low voltage installation labor charges, PoE based connected lighting installations tend to be significantly more cost effective than traditional lighting installations. However, the actual savings varies for each market and is heavily influenced by the local labor charges.
