LAN


Gemini designs and installs voice and data copper cabling, fibre optics and wireless solutions to cross section of industrial and small and medium enterprize customers.

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.

LAN cabling


Local Area Networks are the basic means by which we provide access to a variety of information resources. LANs are usually limited to a specific location, such as a site or department. At the heart of every IT system is the data cabling infrastructure, the nuts and bolts that hold the whole system together. Without a good quality data cabling system data will be transmitted slower, information can be corrupted or lost and, in the very worst cases, systems will simply fail to run.

Modern IT systems transmit data at up to 10Gigabits per second (10 billion bits per second).  Cat 6 has been approved for publication by the EIA. Category 6 is capable of transmission frequencies up to 250Mhz and has a positive power sum attenuation to crosstalk ratio upto 200MHz using improved cables and RJ45 connectors. From Cat5, Cat5e to Cat6 and beyond, Gemini has the engineers and the skills to install or upgrade your network. Gemini offers a fully warranted cabling supported by its principals.From a simple network point test to the installation of a fully operational system, customers can rest safe with Gemini.

As cabling systems become larger and the need to transmit data at ever increasing rates becomes greater the case for fibre optic cabling becomes more relevant. Whether it is used in the vertical backbone or to link buildings across a campus, fibre optic cabling offers the modern, cost-effective solution.

Optical fibres are now used in almost every aspect of the communications network and are widely accepted as the ultimate structured cabling medium. Gemini supplies full optical cabling solution incorporating an extensive range of cable and connector types, supported by the required patch panels, joints, patchcords, and other accessories necessary to effect a complete optical installation whatever the intended application or environment.Our extensive experience of fibre cabling throughout the last 3 decades enables us to offer you the optical fibre solution you need.

Gemini also offers maintenance contracts on all existing cabling systems large or small.

Gemini's experienced engineers will survey your site and offer, where possible, a detailed account of your system structure and any recommendations to improve performance.

Voice Cabling


Gemini's experience and knowledge of voice cabling is second to none. The voice cabling often provides the interface between the Private Automated Branch Exchange (PABX) and the structured cabling system. To facilitate ease of management Gemini can present your PABX extensions on 25 or 50 port RJ45 patch panels so that voice services can be easily patched through to the appropriate work area outlet. Where workers are spread across multiple floors of a building or multiple buildings of a campus then Gemini can provide multi-pair backbone cables to link the various work areas. For companies looking at voice and data convergence Gemini offers Voice Over IP (VOIP) solutions on demand

Most of our engineers began their careers in this field and have over the years progressed to become excellent all round communications specialists.


IP Surveillance


Introduction


Closed circuit television systems have been a major tool for physical security for nearly 5 decades. These systems require guards to watch monitors, remotely control cameras, and change and store videotapes. These systems are not upgradeable and not easily integrated with physical security devices, so their functionality remains fixed from the day they are installed until the day they are thrown away.

With IP-Surveillance most of the “action” moves to the camera, including “intelligence” functions like motion detection and others. For IP-Surveillance, the recording function is performed by a network video recorder (NVR), which is a standard PC Server loaded with video recording software. When compared to the DVR, the IP-Surveillance solution sacrifices no functionality; it simply moves it from the DVR to the camera.

Wide variety of monitoring options:

  • High Resolution Digital Quality images
  • Supports multiple monitors
  • Supports “wall-of-monitor” software
  • Supports remote viewing

Wide variety of playback options:

  • Instant search and retrieve from archive database
  • Instant search on time, date, or activity alarm
  • Instant playback with optional audio
  • Digital zooming into recorded images
  • Export of recordings in JPEG or AVI format, audio in Wave

Remote WAN Accessibility (via the Internet)

  • Managed via VPN rules to assure secure remote access via LAN and Internet
  • Multilevel password protect
  • Worldwide remote viewing
  • Worldwide access to video archive
  • Remote PTZ and record control via Web

Growing list of advantages of IP-Surveillance

A. Standards-based Open Architecture

  • Inherent cost advantage due to open systems components and architectures
  • Interoperable with other network appliances
  • Can utilize existing IP infrastructure
  • Standard video compression techniques
  • Leverage emerging wireless trans mission technologies

B. Functional capabilities

  • Remote and shared viewing via Internet
  • Remote and shared viewing via wireless
  • Facilitates Intelligent Surveillance
  • Windows based to integrate with emerging software
  • Facial Recognition
  • GIS
  • Object Recognition
  • License plate recognition
  • Automated alert/response
  • Automated email generation

C. System Benefits

  • Scalable – DVR systems must be added in blocks of 16 channels. IP-Surveillance cameras an be expanded one-by-one. Systems can expand with the addition of more disk space and more servers.
  • Increased functionality per camera (either at the camera or in management software)
  • Various sensor inputs
  • Relay I/O
  • Motion detection
  • Motion dead areas
  • Selectable frame rates
