Home Security Monitoring

Posts Tagged ‘Don’

Little Rock,AR-According to the FBI, a burglary occurs every 14 seconds. Don’t wait until it’s too late for a security system. ADT monitored home security promotions are available in your area. Call today!

Many people don’t appreciate a home security system until it actually goes off. That’s the story I got from my next door neighbor at four in the morning a week ago this past Friday. Torn from a deep sleep by the klaxon-like baying of Randy’s burglar alarm – Randy’s my neighbor – I wandered over to his house about 30 minutes after the police had gone. While the police hadn’t made an arrest, Randy’s home security system did the job, scaring away the burglar before he had entered the house.

If what happened to Randy isn’t enough to convince you that home security systems can pay for themselves many times over, consider the fact that insurance companies will substantially discount insurance premiums for a private home outfitted with a security system or burglar alarm. My own insurance company discounts my home owner’s policy by twenty percent because I have a security system installed and monitored by a nationally certified company. The savings make a big difference in defraying the cost of my alarm system.

Home security systems come in many different flavors and are able to detect events ranging from forced entry to smoke, fire and even high levels of carbon monoxide. A plain-vanilla setup consists of a keypad, motion detectors and a link to a monitoring center that contacts the police or fire department if the alarm is triggered. Costs for a basic system usually amount to about one hundred dollars for installation and then a monthly monitoring fee that normally ranges between thirty and forty dollars.

Finding the right company to install your home security system needn’t be a tedious job. You’ll usually have a number of friends and relatives who already have security systems installed and they’ll be happy to make a personal recommendation. If you don’t know someone who already has a system, take time to visit the website of the National Burglar and Fire Alarm Association (NBFFA). They’ll be happy to supply information about home security systems and recommend companies in your area that install home security systems and provide monitoring services.

Depending on your location, your list of companies will probably include such nationally known names as ADT and Brink’s Home Security, along with many local companies. Try to narrow the list to three to five companies located in your area. Good selection criteria include membership in the NBFAA, as well as participation in the industry’s Installation Quality (IQ) Certification Program. The IQ program gives consumers a yardstick for identifying alarm companies that are active in quality and false alarm issues.

Once you’ve narrowed your list, call each company and arrange a meeting with a company representative in your home. Price isn’t necessarily the most important issue in selecting the company to install and monitor your security system. Here’s a quick checklist with questions to ask and things to do:

How many years has the company been in business? Longer is better!

Will it monitor your home security system’s operation twenty-four hours a day, seven days a week, fifty-two weeks a year? Make sure they’re working 24/7/365!

Does it have a backup power supply so it can monitor your home even when the power goes down? A good company will continue to operate, even when the lights go out.

Does the company have an in-house training program and are employees well-trained so they are able to correctly install, monitor and service your system should repairs be necessary? Make sure the answer to this question is yes!

Finally, have the representative survey your home and explain in detail your security needs and options. Don’t forget to get a written list of recommendations and a quote in writing for the cost of the security system and monitoring services.

Once you’ve met with the companies on your list, compare equipment, services and pricing. Then, make the call and have your system installed. And don’t forget to cut your premiums by telling your insurance company that you’ve installed an alarm system.

You’ll probably never need your home security system, but you’ll sleep better for having it, just like me and my neighbor Randy.

WHY IS SEA WATER VERY HIGH IN SALT CONTENT?

The average salinity of sea water is about 3.5%. One cubic mile of sea water contains 166 million tonne of salt. The salts of the sea come from the breaking up of rocks and gradual wearing away of mountains releasing salts that are washed down by rainwater. It is estimated that more than 400 million tonne of dissolved salts are brought to the sea every year by 27,000 cubic km of water. The second source of salt is rocks beneath the ocean bed. There has been a constant slow addition of sea salinity due to evaporation from the ocean surface, combined by discharge from land.

WHAT IS A CHEMICAL BOND? HOW IS IT FORMED?

A chemical bond is one in which atoms of different or same elements combine to become stable. There are two types of chemical bonds —electro-valent bond and covalent bond.

WHY DON’T THE TEETH OF ANIMALS DECAY THOUGH THEY NEVER BRUSH THEIR TEETH?

According to WHO, decaying of teeth is a localized, post-eruptive pathologic external process, involving hard tooth tissue and formation of cavities. There is demineralization of teeth by acids produced in the oral environment, due to action of oral acidogenic bacteria on carbohydrates found in cooked food and drinks. Animals are either herbivorous or carnivorous or both, and survive on uncooked, raw food, rich in fibre, which needs a lot of chewing to digest, thereby cleansing the teeth naturally It is like brushing teeth and massaging gums the natural way But tooth decay is common in pets like dogs, which eat cooked food and junk food like biscuits etc.

WHAT IS THIGMOTROPISM?

Thigmotropism is the growth of a plant around a support. Tropism is a phenomena by which a plant, usually climber like money plant and ivy, responds to a stimulus. Stems of the pea plant, for instance, are weak and have coil-like structures called tendrils. When tendrils approach a support (stick), a phytohormone called auxin is released in the side of the tendril away from the support. Auxin, a growth hormone, elongates the cells of that portion and makes it strong. The other portion, devoid of auxin, becomes weak and coils around the support.

WHY DO THE EYES OF SOME ANIMALS GLOW IN THE DARK?

Some animals have a special, reflective surface right behind their retinas, called the tapeturn lucidum, which helps animals see better in the dark. When light enters the eye, it hits a photoreceptor that transmits the information to the brain. But sometimes light doesn’t hit the photoreceptor, so the tapetum lucidum acts as a mirror to bounce it back for a second chance.

WHY DON’T WE FEEL THE TONES OF ATMOSPHERIC PRESSURE? 

Atmospheric pressure, which is about 1 kg per’sqcm of area, presses down on our body from all sides, but we don’t feel it as it is balanced by fluid pressure from inside our body We can feel the difference during rainy season or when we go. to places where atmospheric pressure is less, like hill stations, where due to higher fluid pressure, blood oozes out in blood vessels, making the skin over those pink. The reverse happens under water.

WHY DO FOOD PACKAGES CARRY KCAL WHEN THEY ACTUALLY SPECIFY CALORIES AND NOT KILO-CALORIES?

Kilocalories are commonly known as calories and abbreviated as kcal. One calorie (Kcal) has the same energy value as 4.186 kilojpules-(kJ), while one kilojoule is equivalent to 0.24 calories. One calorie contains the amount of energy that raises the temperature of one litre of water by 1 degree Celsius.

WHAT IS SPIDER SILK?

Spider silk, also known as gossamer, is a protein fibre spun by spiders. Spiders use their silk to make webs. They can also suspend themselves using it.

Employees hope to put pressure on the company and force it to meet their demands.

WHAT IS UNBREAKABLE GLASS MADE OF, AND IS IT REALLY UNBREAKABLE?

The presence of micro cracks on the glass surface (called Griffith’s micro cracks) makes glass breakable under tension or impact. Such micro cracks are unavoidable as the glass surface comes under tension while cooling from a high temperature into various shapes. However, one can increase its impact resistance by various methods, so it can withstand even the impact of a bullet. The idea is to remove the surface micro cracks by chemical etching, or putting the glass surface under compression by physical or chemical toughening. One can even laminate two such toughened glass plates with resin in-between. These glasses are unbreakable, but when the threshold value is very high, it eventually breaks or cracks.

WHAT IS UNIVERSAL TIME COORDINATED?

Universal Time Coordinated (UTC) is a time standard based on International Atomic Time with leap seconds added at irregular intervals to compensate for the Earth’s slowing rotation. A leap second is a positive or negative one-second adjustment to the UTC scale that keeps it close to Mean Solar Time at the Royal Observatory, Greenwich. The difference between UTC and Mean Solar Time is not allowed to exceed 0.9 seconds, so if high precision is not required, the general term Universal Time may be used. Time zones are expressed as positive or negative offsets from UTC. While each day contains 24 hours and each hour 60 minutes, the number of seconds in a minute can be 60,61 or 59.

HOW DO SENSOR DOORS WORK?

Sensor doors use motion sensors or presence sensors. The first are used to activate the door when it detects a moving object, such as a pedestrian or shopping cart. Motion sensors can distinguish between objects moving toward the door or away from it. They use microwave technology and utilize the Doppler Effect principle. The sensors emit a high frequency microwave signal — when the wave encounters a moving object, it bounces back and its frequency changes in proportion to the object’s speed; Presence sensors detect both moving and non-moving objects in the path of the door. Presence sensors use infrared technology — they emit an invisible pulsed light signal. The receiver looks for the reflected signal and reacts.

WHAT IS WEISURE?

Comets have been known to mankind since eons, hence it cannot be said that comets were discovered by any single individual. A comet, like planets and asteroids, orbits around the sun — with fee orbital period varying from a few years to thousands of years. A comet is formed of rock, ice, dust and a few frozen gases like carbon dioxide, carbon monoxide and methane. When a comet is close to the sun, the radiation from the sun causes the volatile matter in the comet to vaporize and spread out into space in the form of its tail, its dust particles and ions glowing due to sunlight falling on it.

WHAT IS HAY FEVER AND WHY IS IT SO CALLED?

Hay fever is a form of allergy belonging to a group of maladies including hives, asthma and skin problems caused by protein sensitization.During certain seasons, many plants, grasses release their pollens into the air in large quantities.

It is called hay fever because the symptoms of the disease appear during spring and fall in England.

HOW IS THE HEIGHT OF WATER TIDES PREDICTED?

As astronomical data is not sufficient to calculate tides, predictions are also based on actual tidal measurements in many areas, over ah extended period. A network of tide stations is equipped to take the following measurements every six minutes: tide levels, wind speed and direction, water current speeds, directions, air and water temperatures and barometric pressure. Stations that provide these daily predictions are called reference stations. Other stations are subordinate stations, which obtain predictions by applying a specific formula to this data. The formula is derived by observing how tides at the two stations related to one another in the past.

The Minskian Ponzi deal was a theory propounded by American economist Minsky, in 1986. Such deals are both unsustainable and hazardous. In Minsky’s view, periods of economic and financial stability lead to a lowering of investors’ risk aversion and a process of releveraging. Investors borrow excessively and push asset prices excessively high. In this process, there are three types of investors/borrowers. First, sound or hedge borrowers who can afford to pay on their own. Second, speculative borrowers who can only service interest payments out of their cash flows. Finally, there are Ponzi borrowers who can service neither interest nor principal payments, and need to keep on refinancing their debts.

WHAT IS A SINKING FUND?

It is a fund set aside as a means to repay funds borrowed through a bond issue. The issuer makes periodic payments to a trustee who retires part of the issue by purchasing the bonds in the open market. Rather than the issuer repaying the entire principal of a bond issue on the maturity date, another company buys back a portion of the issue annually, and usually at fixed par value or at the current market value of the bonds, whichever is less. From the investor’s point of view, a sinking fund adds safety to a corporate bond issue: with it, the issuing company is less likely to default on repayment.

WHY DOES SNOW LOOK WHITE BUT WATER IS COLOURLESS?

Snow is a block of individual ice crystals arranged together. When a light photon enters a layer of snow, it goes through an ice crystal on the top, which changes its direction slightly and sends it on to a new ice crystal, which does the same thing. Basically, all the crystals bounce the light all around, so that it comes right back out of the snow pile. It does the same thing to all the different light frequencies, so all colours of light are bounced back out. The ‘colour’ of all the frequencies in the visible spectrum combined in equal measure is white, so this is the colour we see in snow.

WHAT IS THE FULL FORM OF AK-47 AND WHAT DOES 47 REFER TO?

AK-47 stands for Russian Avtomat Kalashnikova 1947 (Automatic Kalashnikov 1947). Designed by Russian Mikhail Kalashnikov, it was the assault rifle used by most Eastern Bloc countries during the Cold War. The rifle was adopted and standardized in 1947, thus the name.

HOW IS THE TIME DIFFERENCE BETWEEN TWO COUNTRIES CALCULATED?

The earth has 360 imaginary lines called longitudes or meridians running vertically between the poles. Each of these longitudes is called a degree. The 0 degree longitude passing through Greenwich, near London, is considered as standard and the time of all other time zones are calculated accordingly. The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on. In India, the standard meridian is 82-and-half degree. So the time difference between Greenwich and India is 82.5 x 4, which is 330 minutes (5 hours 30 minutes).

HOW ARE ULTRA-VIOLET RAYS BLOCKED BY THE OZONE LAYER?

The ozone layer contains ozone molecules — 03 molecules — which are formed by the action of ultra-violet rays on atmospheric oxygen. This oxygen, which is 02, converts into 03 when UV rays fall on it. When these rays fall on the surface of the atmosphere, they are absorbed in the conversion of oxygen into ozone. As a result, ultra-violet rays are blocked by this ozone layer.

HOW IS THE TEMPERATURE OF A STAR MEASURED?

As stars are very far away, their temperatuce cannot be measured directly. Fortunately, the light coming from stars can be analyzed through several scientific instruments. Although all stars appear white, they have different colours when carefully viewed. The variations are a result of their temperature — cold stars appear red, and hot ones blue or white. The colour of a star is measured by an instrument called photoelectric photometer, which involves passing the light through different filters and finding the amount that passes through each filter. The measures from the photometer are converted to temperature, using standard scales.

WHY DOES A FALLING OBJECT HAVE NO WEIGHT?

Every body on this earth is attracted by the gravitational pull of the earth. A freely falling object has weight W=mg, where W-weight, m-mass of the object and g-acceleration produced due to the earth’s gravity An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.
