It doesn’t matter whatever age you may begin your driving lessons, the possibility is both exciting and nerve wrecking. Driving will bring you a whole fresh found independence. If you’re young and just starting out, a chance to drive yourself wherever you wish without depending on your folks is priceless. For those starting driving sessions slightly later in your life you’ll discover you’ve more independence and a new kind of self-belief.

Things to keep in mind when beginning driving lessons

A vey important decision you’ll make when you choose to start driving lessons is who to choose as your instructor. It is essential to go with a teacher that you feel comfortable with. Your driving instructor needs to be properly accredited and also posses patience and understanding, this is the key important requirement for those worried new drivers.

How to get a excellent driving instructor

Finding an instructor is straightforward, if you live in Plymouth for instance why not use good old Google to look for instructors, just enter in ‘driving lessons Plymouth‘ and you will then obtain their internet site and contact details. Local knowledge is a really important skill that a good approved driving instructor will posses. First time drivers really need to first become accustomed to handling the car so the instructor needs to be able to take the pupil to a secluded road. If for example you hire a driving instructor in Exeter, they ought to either reside in the area or nearby so that they are familiar with the roads and daily traffic such as work and school access.

You and your driving instructor

It is important you will get on with your instructor, you need to be able to clearly understand their guidelines as this will quicken your progress. Many people begin with one driving instructor and then switch to another, don’t be afraid to do this. If you are going to pass with flying colours, you need to be in a position to work with your instructor.

CCTV and surveillance technology is constantly evolving and today’s digital IP cameras provide increasingly sophisticated capabilities for monitoring, recording and reviewing activity inside and outside your property. With a wide choice of products available, understanding your options can be confusing, whether you’re new to CCTV or planning to upgrade an existing system. Here are the top ten things you need to ask yourself to get the right CCTV system for your needs.

1: Defining criteria
Why do I want to install CCTV?

It’s essential to start with a clear idea of what you want your CCTV system to achieve. What suits your neighbour or another business may not suit you. Are you considering the investment as a deterrent to intruders and thieves? To record access to a building or car park? To monitor movement in particular areas of your property? To record activity round the clock or at specific times, for example when your property is unoccupied? You also need to think about what you want to do with the information once you have it. How long do you want to keep it? How often do you want to review it? With clear objectives, it’s easy to determine the criteria – such as picture resolution, camera focal length and image storage requirements – that will ensure your chosen system is fit for purpose.

2: Basic requirements
What equipment will I need?

Essentially, a CCTV system comprises one or more cameras and either a software- or hardware-based image recording facility. Until recently CCTV cameras operated by transmitting analogue video signals through copper cables to a central location where the video signal was recorded. While analogue cameras still have their place, today’s more sophisticated IP cameras produce digital output and use IP networks to relay their images. The number and type of cameras you choose will depend on the subject and the extent of the surveillance area.

3: Recording options
How can I store images?

Images can be stored on the camera itself, on a computer or on a digital video recorder (DVR). The output from an IP camera is digital and is recorded without change; the output from an analogue camera is first digitised and then stored. DVRs and computer software offer the ability to record multiple channels, ie images from several cameras at the same time, regardless of the camera type. With analogue cameras, the number of channels that can be recorded is limited by the number of physical connections on the DVR, whereas in an IP system it is usually limited by software licensing. The number of camera sources you want to record from, the image quality you require, and the length of time that you want to store those images will all influence which recording device is best for you.

4: Ongoing surveillance
How can I monitor images?

A key consideration in getting the right system is to know how you want to view the images from your cameras. Will you have a central control room with trained operators constantly monitoring screens? Do you want a third-party to monitor your property? Will you want to access your CCTV images remotely while abroad? Do you want to receive email or text alerts if suspicious activity is detected by your CCTV system? IP cameras can be connected to the internet to relay images anywhere, and both IP cameras and DVRs have the capability for motion detection.

5: Static or not
Do I need fixed or moving cameras?

Camera housings can either contain fixed cameras, trained on a single location, or PTZ (pan/tilt/zoom) cameras that can rotate 360° and provide pre-programmed ‘tours’ of an area. Motion detectors can be added to a PTZ camera system so that the camera can respond and focus in on suspicious activity. Depending on the rationale for your CCTV system, you might want a mixture of fixed and PTZ cameras to cover different zones and applications.

6: Camera features
Do I need IP or analogue cameras?

While an analogue camera is ideal if you want to monitor one location from a fixed position, an IP camera is more flexible and can enable more sophisticated surveillance, recording and review. IP cameras can deliver high definition or megapixel images, which give greater detail and can cover a greater range. They can also be powered over a network using Power over Ethernet (PoE), so do not require a separate power supply. Some IP cameras have audio recording built in which allows recorded messages to be broadcast automatically to warn people that they are being watched. However, this functionality can be integrated into any camera’s housing and is not a specific benefit of IP. Both types of camera can also feature infrared technology to capture full-colour images during the day and black-and-white images in low light or even complete darkness.

7: Intelligent security
Should I integrate my CCTV with my other security systems?

CCTV cameras can be easily integrated to enhance your security. When integrated with an intruder alarm, your CCTV system can be set to record images at a higher resolution when the alarm is set or activated. When integrated with an access control system, CCTV can provide additional visual verification that a person has authorised access. Your specific integration requirements will influence the type of camera and recording equipment you need.

8: Investing wisely
How do I make the most of my budget?

This depends on what you want your CCTV system to achieve. IP cameras are more expensive because their image quality is better and they are more flexible, but analogue cameras are often sufficient for the job. If you only need fixed-point monitoring, a low-spec, low-cost analogue system would be the right choice. On the other hand, if you need to monitor a large area, it may be more cost-effective to use one high-resolution PTZ camera in the place of several fixed analogue cameras.

9: Going digital
Should I upgrade to a digital system?

The need to upgrade will depend on what equipment you already have, your surveillance requirements and your budget. By replacing a VHS video recorder with a DVR, the feed from existing analogue cameras can be digitised and more easily stored. The system can then benefit from features, such as motion detection, which are supported by DVRs. IP cameras can also be introduced to work alongside analogue cameras allowing you to benefit from their technology where appropriate.

10: Industry validation
What accreditation or references should I look for in a CCTV installer?

Credible CCTV installers will have industry accreditation such as recognition by the NSI (National Security Inspectorate) which promotes compliance with relevant British and European Standards as well as the requirements of the police and the insurance industry. A reputable company will not have any problem with you asking for their credentials, and should also be able to introduce you to existing customers for reference.

If there was ever an argument for the benefits of fiber optic technology, it played out this summer 2.5 miles under the sea at the wreck of the RMS Titanic.

The Titanic was the largest passenger steamship in the world when she set off on her maiden voyage from Southampton, England to New York City on April 10, 1912.  Four days into the crossing, on April 14, the ship sank—resulting in the deaths of 1,517 people.  As one of the deadliest maritime disasters in history, the story of the Titanic has become timeless legend.

Today, RMS Titanic, Inc., a wholly owned subsidiary of Premier Exhibitions, Inc., is the only entity in the world permitted by law to recover objects from the wreck site of Titanic. The company has conducted seven research and recovery expeditions to the sunken vessel since its discovery in 1985.

However, this August, 23 years after divers first visited the wreckage of the Titanic, a new mission of a different kind was launched. This one, working with the Woods Hole Oceanographic Institution, involved mapping and documenting the Titanic site with the long-term goal of creating an archaeological management plan.

One of the major parts of this summer’s expedition was possible due to recent advances in digital photography, sonar and computer imaging software. Robotic submarines were built to trace a detailed two by three mile grid measuring the wreck site. Software was used to convert that into a 3D digital map of the wreckage.

Fiber optic technology played a major role in the research. One of the robotic submarines, the Remora 6000, which can reach the depths of 6,000 meters, was attached to the research ship, the RV Jean Charcot, by a fiber-optic tether. Telecast Fiber’s tiny three-inch long Rattler 3G was used aboard the Remora 6000 to transmit high-definition and 3D HDTV video and other data via fiber up to the ship.

The Rattler 3G, a flexible device that can conform to a wide variety of video-over-fiber transmission needs, was employed in several configurations on the Titanic project. At one point the Advanced Imaging and Visualization Lab at Woods Hole Oceanographic Institution used over eight HD and UHDTV cameras on the Remora plus some other devices whose signals were multiplexed and sent back to the main ship over a single strand of single mode fiber running more than 32,000 feet.

Thousands of photographs were fused with “location” data, while the bow and stern were closely photographed with the 3D cameras. The imaging was merged with acoustic data to create the largest ship wreak site photomosaic ever made.

Co-expedition leader Dave Gallo called the new technology used this summer “the great-great-grandchildren” of the equipment that first explored the Titanic in 1985. We at Telecast Fiber are proud to have participated in this extraordinary project.
