Features of Different Types of Alarms

 There is a large variety of alarm systems available to those who wish to make their premises safe and secure Some alarm systems are geared more towards monitoring, others are to detect intrusion, others to detect smoke and fire. Below we look at some of those different types.

Burglar alarms
Most home owners who want to install an alarm system will want it to help prevent unwanted intrusion and theft through burglary. Any burglar alarm is in its basic form designed to detect intrusion and raise an alarm. There are three main ways in which this is done:

• detection of motion
• unauthorised opening of windows or doors
• visual detection of intrusion through cameras

Intrusion and unexpected motion can be detected through motion detectors signalling movement to a base unit, sensors on doors and windows signalling that they have been opened, or remote cameras sending visual evidence of intrusion.

Monitors, sensors and cameras can be linked to base units either by ‘hard wiring’ or wirelessly. Most base units will be wired to the premises’ electrical system but will also have back up from an internal battery ensuring they continue to function in the event that electrical supply is cut off either accidentally or intentionally.

Notification
Notification is the term used to describe what the alarm system does when it detects intrusion. Notification can be by siren, an audible alarm that alerts occupants, neighbours and passers by that the system has been activated. These are termed ‘Audible only’ systems.

As well as raising a localised alarm systems are available that notify a nominated person or company by telephone or text messaging; these are called Speech or Voice Dialler systems. The nominated person or company will hold a key to allow access to the premises on which an alarm has been raised. Both landline and mobile telephone networks are used.

More sophisticated is an Alarm Transmission System that broadcasts signals by radio and/or telephone to a continuously monitored receiving centre that then contacts specified persons and key holders. These are known as Monitored Alarms. Some of the options available for this type of alarm also contact Police.

Surveillance
Surveillance systems are typically a system of remote-controlled cameras linked by cable or wireless to a receiving unit that displays the visual information. This is monitored and evaluated by an operative who then makes a decision as to what action should be taken.

Surveillance cameras can be added to a burglar alarm system to allow occupants to visually assess any callers or intruders.

Fire alarms
Fire alarms use smoke and heat detectors to raise an alarm when fire is detected. There are three different types of detectors normally used with fire alarm systems:

• ionisation detect small smoke particles
• optical detect larger particles
• heat detect increase in temperature

These detectors are linked to a base unit which sets of an alarm.

Smoke alarms
Most homes will now have smoke detectors either built into the domestic electrical system or added. Detectors can be hard wired into the electrical system with back up power from a battery in case the electrical supply is interrupted, or can be ‘stand alone’ units mounted on ceilings and powered by a battery that needs to be regularly changed.

Risk assessment
It is worth remembering that a thorough risk assessment should be undertaken before any choice is made regarding which alarm is best suited to any premises. These assessments are very often carried out by companies that supply alarm systems.

Technical Information About Two Companies: Apple

Apple was established by Steve Jobs, Ronald Wayne and Steve Wozniak. The company started by making personal computers but soon diversified into other types of technology. Today, Apple is one of the world’s most recognised companies, with products like the iPhone and iPad must-have tech items for millions of people. The company is, perhaps, best known for its innovative design. Apple products are minimalist, chic and carry an almost-uniform design (sharp edges, contemporary shapes etc.). They have inspired several startups with their unique approach to aesthetics.

Apple has also proved extremely popular. After an initial boom, the company faced competition from Microsoft, another brand that specialised in personal computers. During the 1990s and early 2000s, Microsoft’s products and operating systems became the status quo. However, this was soon to change with the introduction of brand new tech like the iPod. This product revolutionised portable music computers, letting users download music tracks from the Internet. They could then play music on their personal devices. iTunes, a digital music platform, lets users customise their own playlists and choose from various genres.

Then, the iPhone launched, instantly becoming one of the most popular smartphone brands in the world. Users could listen to music just like the iPod but could also make calls and browse the Internet. The iPod Touch combined elements of both the iPhone and iPod, transforming the appearance and functionality of music players. The iPad, which has seen several incarnations over the last few years, was another game changer. This tablet lets users browse the Internet on a sleek screen with touchpad compatibility. Just like the iPhone, users could access the App Store and download applications onto their device. The online store included games, photo editing software and educational resources.

Recently, Apple branched out into smartwatch technology. The new iWatch has already proved a huge success and lets users access the Internet from their wrist.

Technical Information About Two Companies: Samsung

Samsung dates back to the 1930s, making it older than Apple. The company was established by Lee Byung-Chul and started making consumer electronics in the 1970s. In recent years, the company has also transformed digital media. The Samsung Galaxy range lets users access the Internet from their mobile device, talk to friends and family online and download applications.

The company has produced a plethora of smartphones and tablets and has pioneered a range of new technologies. The company has also cornered markets that Apple hasn’t: Samsung televisions can be found in homes around the world.

Samsung is based in South Korea and continues to innovate.

Takeaway

Samsung and Apple are two tech success stories that have dominated consumer electronics over the last few years. Today, Samsung televisions and Apple iPhones are owned by hundreds of thousands of people around the globe.

The best ways to optimize the functioning of your laptop

The Best Ways to Optimise the Functionality of Your Laptop

Laptop surrounded by sports training equipment and healthy food, weight loss, workout and technology concept

 Have you been looking for information about laptops and how to improve their functioning? If so, there are several methods to be examined should you find that your device seems to be lagging. Let us take a step-by-step look at some of the most effective (and simple) ways to ensure that your laptop remains fast and reliable.

A Basic Physical Examination

If you find that certain aspects of your laptop have suddenly stopped functioning such as the keys, the USB port or the mouse pad, make sure that there are no physical obstructions such as dirt or crumbs. It could also be a good idea to use a spray air cleaner to remove any debris that may be hard to reach otherwise. If you choose to remove the keys, be certain that they can be reattached when you are finished. Avoid sticking any foreign objects into the USB port. You can examine the link at http://uk.pcmag.com/input-devices/8458/feature/laptop-keyboard-not-working-heres-what-to-do for more details.

Run a Speed Test

There can be times when your computer seems to be running extremely slow. Is this due to an Internet connection or a memory issue? One of the best ways to determine this is to perform an online speed test. This quick and simple examination requires no type of download. Instead, a dedicated website will send small packets of data to your laptop and examine the “lag time” between when they are received and when they are transmitted back from the computer. If you find that this time is very slow, an Internet connection is likely to be the problem.

Utilise Anti-virus Software

Another common issue that laptops will encounter from time to time is the presence of viruses and other types of malware. Not only can a virus be a nuisance, but there may even be chances that your system will become corrupted. The best way to be certain that this is not the case is to download and install trusted anti-virus software. While free scans can be helpful, keep in mind that they may not detect all issues and in the majority of cases, they do not have the ability to remove any infected files.

Perform a Disk Defragmentation

Much like a room that has not been cleaned in a very long time, your hard disk drive (HDD) can become “cluttered”. This could be the issue if you have noticed that the laptop has been running progressively slower over the past few months. Your system has a built-in defragmentation option. This frees up memory as well as detects and deletes damaged files.

The System Restore Option

Assuming that none of these steps work, you have the option to restore your operating system to a previous date when the laptop was functioning properly. However, be sure to back up all of your files to make certain that they are not lost during the process.

This is only some very basic information about laptops and how to improve their functioning. If you find that none of these tips have helped, it is best to speak with a trained professional. He or she will likely be able to provide you with additional advice and options.

What has the new iphone 7 got to offer

What Has The New iPhone 7 Got To Offer?

 Exciting New Additions

Apple showed off their latest water resistant brighter iPhone 7 next to its larger option, the iPhone 7 Plus, on September 7th. The new iPhone 7 is a state-of-the-art brilliantly designed, perfected unification of software and hardware. This is the best iPhone so far, and its functions are extremely fast. It beats all the rest of the iOS devices, and is substantially quicker than Samsung’s most resent offerings.
While this latest model, which comes in an exciting range of colours, resembles the iPhone 6 and 6s, there are a number of innovative changes. Firstly, its antenna is now integrated inside the enclosure, making the phone less cluttered, which is also helped by the removal of the 3.5mm headphone jack. The colour choice includes: matt or gloss jet black,rose gold, gold and silver. The water resistant level is covered by an IP67 rating.

Great Improvements

The list of improvements include the A10 Fusion processor which offers another substantial speed bump set that has two cores.a front facing home button which is now static-state and force sensitive; as well as meliorated vibrations and sounds which the phone gives off when the user makes an action. This is because Apple have updated this model’s “taptic engine,” and so all its vibrations sound more distinct and sharper. Now, changing to silent mode just needs a speedy tap, and different settings and sounds also offer phone rumbling improvements. And when the user adjusts the time of the clock, you can wheel’s click can be felt whilst you spin it.

Better Quality Pictures

The iPhone 7 boasts a 12-megapixel camera which incorporates a new internet service provider, a brighter flash comprising a four-LEDs flash which helps light up a shady room. There is more cutting-edge OIS (optical image stabilization), and a marginally broader aperture lens, which also allows more light in when you are taking photos at dusk and in low-light surroundings. The OIS feature is very useful, as it allows iPhone 7 users to take clear photographs, even if their hand is shaky. Also, as the live photo aspect works to slow down the speed of the shutter, it can be switched off for speedier takes. And The FaceTime front facing camera is now higher at 7 megapixels, which is great news for anyone who loves to take videos or selfies.

Getting More From A Speaker Unit

The phone’s receiver at the phone’s top has also been upgraded with a more professional speaker unit which offers the same power level as the receiver at the end of the phone. This makes it much better for listening to someone you are on a call with, especially if you are in a noisy environment such as road traffic. And if the user is not speaking on the phone, they can change the device to landscape orientation so they can hear music in stereo. This is because the two speakers have been engineered sufficiently apart.

Greater power Efficiency

Better battery power is another great iphone 7 feature, and Apple’s strive to greater power-efficient processing will be much appreciated. There is a mode for lower power battery optimization attached to two other cores, and the phone automatically changes between them.

The best reasons to choose an unlimited data plan

The Best Reasons to Choose an Unlimited Data SIM Card

 In a world now defined by 4G speeds, the rapid transmission of data and dedicated smartphone applications, the ability to save money on a monthly mobile contract is always attractive. One of the best ways to enjoy the best of both worlds is to utilise what is known as an unlimited data SIM calling plan. What are some of the reasons why consumers would select such an option and what can you expect to take advantage of when compared to a more traditional contract? The answers to these questions may surprise you!

Truly “Unlimited” Data

One of the first things to appreciate is that many providers claim to offer an “unlimited” plan only to have this data usage capped at some point. Unfortunately, this is normally only discovered after reading the decidedly fine print within the terms and conditions. The options offered at 3 data sim are made quite clear from the very beginning. Customers will know exactly what it is that they are receiving.

Not Just Data Alone

Another advantage that is normally associated with unlimited data plans is that they can be purchased alongside some of the most modern smartphones in existence. Some examples here include:

  • The Huawei Y3
  • The Samsung Galaxy S7
  • The Apple iPhone 6S
  • The Samsung Galaxy S6

Not only are the plans themselves amazingly economical, but these phones are a handful of the best in the industry. Impressive graphics, user-friendly interfaces and superior levels of reception are now realities.

Avoiding Needless Contracts

Over the years, many smartphone contracts have become complicated and convoluted. Customers might not be sure what they are receiving and in some cases, they may be paying for services that they hardly ever use. One example can be if a customer requires a phone to work remotely but rarely uses this phone to make calls. He or she may very well be charged a flat rate for minutes that are never used each month. Such a needless expenditure can be avoided with unlimited data SIM cards. In other words, these cards are specifically designed for those who require large amounts of data alone. They can certainly be one of the most economical choices.

At-Home and Public Access

Modern technology has allowed unlimited data plans to provide streamlined services whether one is at home or out and about. Some data limits can be as high as 25 gigabytes while at home and up to 12 gigabytes when at a specific public location (such as a coffee shop or an Internet cafe). Thanks to 3G and 4G reception, accessing online portals has never been easier.

Different Phone? No Problem

Unlimited data SIM cards also offer an amazing level of flexibility. Should one need to upgrade his or her current phone, there is no need to be concerned with having to cancel a contract. The card can simply be taken out of an existing model and placed into the new device.

These are some of the benefits that plans such as those found http://www.store-3.co.uk/3-unlimited-data-one-plan.html will provide. Please have a further look to determine which option may be the best for you.
