Home Intercom Systems Installation

Home intercom systems are used as a private communication home network in a small building or a group of small buildings. It is deployed to utilize the resource for communication in a small defined area. This intercom networks are basically wired but are available in wireless constructions also. These are administered independently without any intervention of public network. It can be used with a public network also.

It can be taken as a division of a single phone into a number of significant units. All the units have separate functionality and can be used on both a public and intercom network. There is a criteria of extensions defined that can be used to connect to the intended person of contact. These intercoms can be a permanent system and can be portable systems. The efficient use of home intercom systems has led to the increased demand. Maximum apartments, societies and small buildings are deployed with intercom systems. These intercom systems reduce high landing call charged in public communication systems, in fact this system provides efficient and managed free calls between the local receivers.

This system has led people to find an efficient technology to escape paid public networks to free, efficient intercom services. There may be issues in the public network sometimes due to some technical problems in the system but installations of intercoms are safe and managed and also provide high availability over its domain area. This system enables a neighbor to talk to the other neighbor on the intercom free of cost. There may be some maintenance charges may be cost to maintain the system in working condition but that has no comparison with the six pence made in the public network. Suppose if you want to talk to your neighbor just in the same building you live in, on some hot sunny day and you do not want to move out of home this intercom will help you to make free unlimited clear calls to your neighbor. Now suppose if you call the same neighbor on the public network that surely will cost you a lot. This system also enables a conference call that allows other people to join the call simultaneously. This may help you to get efficient access among your neighbors.

You don’t bother talking to your neighbor just because the public network costs you a lot of hard earn money. A home intercom system installation will ease your relation with your neighbor.

Home Security Systems – Using Home Security Sensors to Burglar-Proof Your Home

Getting a home security system is not something to put off for the future, to jot down on that list along with getting fit and picking out a great outfit for your cousin’s wedding. It’s something that should qualify as a top-level priority for anyone seriously concerned about their own well-being, that of their family and that of their personal possessions. These days, installing a security system is far from being the colossal hassle it was in previous years, when the technology was still fresh and adequate knowledge confined to those with an understanding of sophisticated electronics and complicated, arcane computer user interfaces. Wireless security cameras and home security sensors, of both the infrared and contact variety, are sufficiently easy to install that you can learn all you need to know in an hour of web-surfing. What’s more, they’re cheap enough to make the cost-risk equation a real no-brainer.

Wireless security cameras: simple and easy to install

It’s possible to set up a wireless webcam to serve as your personal, wireless security camera, even if you possess the tech-savvy of an 8-year-old. These devices, which are getting smaller by the day even as the resolution available increases to levels of sharpness far beyond the human eye, can be concealed in any desktop ornament – you can install them, Hollywood style, in teddy bears, toys, paperweights, even behind two-way mirrors. It’s as simple as drilling a hole in your table or mantelpiece for a feeder cable, cutting a sufficiently wide lens-hole in the side of the ornament to be used as their disguise, and arranging the camera within it. By running the feed cable to a USB port on your computer, you can simultaneously charge the device and record footage. Simple motion detection software, such as that available for download at Bit.ly, can ensure that your computer records only when there’s a disturbance in the camera’s visual field, making your new home security system both functional and efficient.

Save disk space by making the most of your home security sensors

It’s also possible to have the device activated by various kinds of home security sensors. Infrared sensors activate when an object of sufficient heat moves across their detection field. Contact sensors, by contrast, are activated by the opening of a window or door, an action which either opens or closes the circuit made by the two installed sensor pads, which in turn sends a signal to the central home security system hub to which the sensors are wired. Another type of home security sensor utilizes UWB (ultra-wideband) radar. For the purposes of motion detection, these sensors function by ‘staring’ over a fixed range and sensing any change in the average time taken for the signals the device emits to be returned.

These are the same kinds of motion sensors that activate your porch light when someone walks across the driveway. The technology has been around for a long time, and has just about been perfected, to the point that upper-range home-security systems incorporate sensors with pet-human discrimination technology. PIR detectors can be made to discriminate between pets and humans by use of a modified lens or mirror that vertically stretches the zones in regions closer to the sensor, an effect that reduces the size of the ‘blip’ created by, say, a cat, and increases that created by a person. The industry term for such discriminator home security systems is ‘pet immune’. Wireless security cameras can be programmed with software for a similar effect.

If you plan to install a home security system incorporating wireless security cameras and home security sensors all by yourself, there are a few important considerations you’ll want to keep in mind. One is location. Ideally, cameras and sensors should cover those areas through which an intruder will have to pass in order to access the house. So doors, windows and skylights should be first. Be more concerned about those entry points that are off the street and shielded from public eyes, as they’re the ones morel likely to be used by intruders.

Sign up with a good security agency

Perhaps even more importantly, you’ll need to think about the monitoring of your system. If you’re going fully independent with your system, the best thing you could possibly do is install a loud alarm siren to be activated upon intrusion, or, if you’re really willing to go the extra mile, an automated telephonic system to contact the police with a looped, pre-recorded voice message. Neither of these options is as effective as being signed up with a good home security company. Home security companies, such as ADT, offer better response times than police in most parts of the world. Furthermore, if consulted from the beginning, such security companies will install your wireless security cameras and home security sensors in a fully integrated home security system that they’ll be responsible for monitoring – which, for a relatively small fee every month, will really be the ultimate assurance of peace of mind.

Buying a Home Security System FAQ’s

How do I know what to buy?

Unless you’re comfortable taking all the responsibility for your family’s security and you’re an avid do-it-yourselfer, your best bet is to call a professional. Most security companies provide a no cost evaluation and will make appropriate recommendations for your home.

How expensive is a home security system?

Home security equipment costs can range from nothing upfront to well over $1,000. It depends on the features that you want and whether you are buying the equipment or leasing it along with a monitoring agreement. Some security companies will provide the basic equipment for free or a minimal fee when you sign a contract for their monitoring service but have additional charges for additional sensors and functionality. Comparison shopping for the specific features that you need can save you a bundle.

You can also buy a variety of home security equipment from home centers and electronics stores. There are single window/door alarms for as little as $10 or you can custom design a system to fit your needs. Just as using a security company, each window, door or other area of protection will generally cost more money.

Are there recurring costs for a home security system?

If you go for a monitored system, you’ll incur a monthly fee that will range from as little as $6 to well over $50 depending on the company and the options that you choose.

There are many companies in this business and they all offer a variety of plans. There are also differences in the reliability and type of monitoring from company to company. Monitoring plans are offered for basic burglary protection to live video from anywhere in the world and everything in between. The largest companies with great reputations tend to have the highest prices but generally offer the best overall service.

What do I need a monitoring service for?

Since most burglaries occur when your home is empty, your security system may not do any good without a monitoring service. A loud siren may scare off a burglar but you can bet that they’ll silence the alarm quickly if they do stick around. Some do-it-yourself systems are capable of dialing out, but beware as a telephone line won’t work after the burglar cuts it. Since most of the monitoring services use cell phone technology as the main or back-up communication method, you are protected even when your phone line is cut.

Do I have to sign a contract with a monitoring service?

Maybe; since there are so many different companies out there, they all have different terms and conditions. Generally speaking, the largest companies in the business as well as any company providing discounted or free equipment will require a contract. Three year terms are typical and I know at least one company that uses a five year contract. These are similar to cell-phone plans as they typically carry hefty penalties for an early cancellation.

If I invest in a security system, what happens if I move?

Most of the security systems installed today are easily moved. As hard wired systems are not cost effective to install, chances are you would get a wireless system that can easily move along with you. Some of the larger security companies have provisions for reinstallation upon moving built into their contracts. If you own the equipment, you can include it when selling your home as a security system does add value to a home for sale.

Can I get a security system if I rent my home?

Absolutely; in most cases the security company would require permission from your landlord prior to installation. I don’t know too many landlords who wouldn’t welcome the idea.

Do I lose my protection if there’s a power failure?

Any decent security system has a battery back-up that would power the system for hours, if not days. So when lights and other things that rely on electricity may not benefit your security during a power failure, you can have peace of mind with a security system.

Does a security company cover any losses from a break-in?

That would be a no. Your homeowner’s or renter’s insurance covers any losses beyond your deductible. The only exception to this is in the contracts of a few companies where a few hundred dollars may be payable if losses are a direct result of negligence on their part. This would usually cover your insurance deductible. The good news about insurance is that you’ll get a discount on your premium after a security system is installed!

Can a security system do more than guard my home from burglars?

Today’s security systems have matured to the point of home automation. Fire, smoke and carbon monoxide detection are very common and thermostat and lighting control are available in many systems. Communication technologies and the internet allow monitoring and complete home control from anywhere in the world.
