What is an Intercom?

An Intercom (intercommunication device) is a communication tool that allows two or more people to carry a conversation or communicate in some manner through different rooms or compartments in a structure (ie. a building, ship, airplane, etc). This communication over an electric circuit device is mostly found mounted permanently within building structures (whether business or residential) or vehicles (ie. airplanes, ships, buses, etc.).

Intercom connections can come in the form of walkie-talkies, telephones, and cell phones over a phone line or data line. Intercoms are used to mainly communicate within a building. For example, you can have an intercom system within your house to monitor what’s going on in your child’s room or to communicate with your spouse or other family member in a different part of the house.

Intercoms come in a variety of styles. Some are extremely easy to use while others can be very complicated. There are audio intercoms, video intercoms, integratable and multi-tenant intercoms. Top of the line intercom manufacturers include Aiphone, Quantometrix and Vitec Group Communications. These companies offer a wide variety of communication systems consisting of audio, audio visual, IP network intercoms, apartment entry intercoms, nurse call, and bowling alley intercoms.

Audio Intercoms

Also known as voice intercoms, audio Intercoms have one main unit and other smaller units in different parts of a building allowing communication between the main part of the building such as a living room or a kitchen and smaller part of the building such as bedrooms or restrooms. Some audio intercoms play music over the system. If you have a baby in the house, audio intercoms can be used as a baby monitor. This allows you to hear when the baby is crying or if the baby is sound asleep.

Video Intercoms

Video Intercoms have the same capabilities as their voice/audio-only counterparts but in addition to voice or audio communication, they allow you to see what activities are going on in different part of the building via a small video screen. This is a great tool for families with kids. Parents or other adult family members can check your kids while they are playing in their room or backyard while they are making dinner in the kitchen. Video intercoms are also useful to find out who is at the door before opening it. Some sophisticated video intercom systems allow you to unlock your front door from a different location.

Business Intercoms

Intercoms provide a number of uses for businesses by allowing them to communicate to multiple employees at the same time. For example, a large office or warehouse full of employees can be reached simultaneously through a single employee’s use of an intercom. Department and grocery stores use intercoms to communicate with both employees and customers. These stores are able to keep customers up-to-date on sales, closing times, or any other subject.

Intercom Systems

Intercoms are made up of different parts, and are thus sometimes referred to as intercom systems. These parts include master or bases stations, door stations, bus stations, belt packs, handsets, headsets, and power supplies. Intercom systems come in a variety of types including Two-wire broadcast intercoms, Four-wire broadcast intercoms, Wireless intercoms, and Telephone Intercoms.

Advantages Of Plain Old Telephone Services (POTS) Lines Over The Modern Telephony

In most parts of the world, plain old telephone services POTS lines, commonly known as landlines, have remained the major form of connection to telephony networks for both businesses and residential users. This is a voice grade phone service dating back to the late 19th century. Though technology has brought a lot of changes, these have capabilities that modern telephony like ISDN, cell phones and VoIP do not.

This could be a major reason that despite introduction of advanced telephony service, most offices and residents still maintain their POTS network. These provide a full-duplex voiceband channel where human voice can travel both ways, concurrently. Other provisions are operator services like conference calling, subscriber dialing and call progress tones. These form the basics of any phone service.

In addition, those with landlines network today can order broadband service if they need their computer systems to run faster. In this case, POTS will act as a basis for the new service since one can now connect to the provider through the existing phone line. Once you add the broadband, your business uses the same cable network for both phone and internet.

It is also good to note that the plain old telephone services lines are very consistent compared to modern telephony. This ensures that your business is not getting irregular cut outs at any time of the day. This is a common problem with the newly introduced technologies like the cellular phones and Voice-over-Internet-Protocol.

Users should note that, both cellular phones and VoIP are greatly affected by weather changes. Other disruptions on these kinds of telephony communication include cell tower location problems, satellite positions and even power interruptions. On the other hand, POTs are highly stable as they will not even need power to operate especially if using it for calls only.

Another advantage of using landlines is that, in case of an emergency where people have to contact 911, the operator can easily tell where this is coming from. This way, the caller can receive immediate help. However, this is not the case with most types of VoIP or GSM phones. With VoIP, ability to instantly track a caller will depend on the service provider. Use of GPS tracking for cellular phones without the service is through cell tower triangulation which may take a lot of time. This means one is not going to receive timely assistance from 911.

There is no special instruction required to operate the POTS equipment. Most of its features are basic and familiar to most people who have made calls before. This means a business will not spend resources training employees on how to operate it. However, this is not so for modern communication systems. Some cell systems may require special training for people to operate.

The above are some of the benefits of using the plain old telephone services POTS lines. Since this can also integrate easily with new technologies, it is vital to keep it along the advanced communication systems. One does not have to completely do away with this kind of network. It can save your business a great deal of money and time especially during an emergency.

The Perpetual Inventory System: The Good and Bad

Inventory management is needed in order to keep track of a company’s goods and services. If you do not know what you have in stock and what products you are selling, then you have no way of maximizing your profits. When it comes to controlling inventory, there are two main systems that can do it. They are the perpetual and periodic inventory systems. The difference between the two is basically the manner in which they are updated. But, for the purpose of this article, we will concentrate on the perpetual system.

With the perpetual system, the inventory is always updated. Whenever an order is placed, received or shipped, the corresponding product will be updated in the system at that exact moment in time. This is mostly possible due to technological advances that allow computers to be updated in real time. When product is received, it is put into the system via bar coding technology. The perpetual inventory system is extremely popular because all retrieved and delivered information is up to date and in real time. You are guaranteed that the information that that is received within the reports is the most up to date information available.

However, if there are any mistakes, it is usually due to human error. The information is only as accurate if it is entered into the system. It cannot be seen, analyzed or corrected if it is never keyed into the system. This is why it is important that all orders are handled at the time that they are placed, received or shipped.

Of course with any type of system there are going to be both pros and cons. Other than real time updating, one of the main benefits of using the perpetual inventory control system is that it is a time saver. For instance, if sales personnel must know how much inventory is in stock before they can sell it to potential customer. This is especially true if the customer is expecting same day delivery. With a perpetual system, a salesman can check inventory stats on his laptop or mobile phone. He has the information that he needs at his fingertips. It is a smart way to check inventory before placing a same day order for a customer and finding out that the product is not in stock.

In the past this one little task would have involved calling someone in the company to check to stock levels. Many times this would have meant sending someone out to the warehouse in order to do an actual physical count of the inventory. Depending on the company and how well it is organized, a simple task like this could take hours to complete. This is why the perpetual system is used by plenty of companies. It saves time by always being consistently updated.

When it comes to the perpetual inventory system, there are few cons. The main complaint is that it requires a hefty investment on the front end. The software for this type of system is not cheap. However, most companies find the system very beneficial, once the software has been purchased and installed. Secondly, as stated throughout this article, the system has to be constantly updated. A lot of information has to be consistently feed into the system in order for it to work properly.

As you can see, the perpetual system has both pros and cons, but it is a very good inventory management system to have.

Ten Impediments to Effective Communication

There are countless reasons why high-quality, effective communication can be difficult. We are all individuals, with different ways of viewing the world, different biases and objectives and vulnerabilities. We so often judge what we see and hear based upon our own experiences and predispositions. We should remember, however, that effective communication begins with mutual respect, a give-and-take exercise that should ideally conclude with a better understanding than was present at the beginning.

The following impediments are worthy of consideration when attempting to improve and augment one’s communications skills:

1. Lack of Focus – What are you trying to communicate? Are you rambling? Are you starting off in one direction and steering toward another? Stay on your message so that your course becomes a straight line.

2. Lack of Clarity – Are you using the right words, expressions, or examples to paint the mental picture? Do you see in the faces of your audience that they get it, that you’re all on the same page? It matters little how fancy your prose or how funny your jokes if the audience connection isn’t there.

3. Lack of Specificity – This deals with precision, and goes a step further than focus and clarity. So, lieutenant, you want us to take the hill. Which hill? And with how many men? And within what time frame? Remember: Who, what, where, when, why, and how.

4. Lack of Enthusiasm – Have you ever heard a speaker say, “We’re excited about it,” with about as much conviction as if he were delivering a lecture on the disposal of cat litter? It’s not necessary to become Richard Simmons espousing the benefits of exercise, but enthusiasm does help in elevating the energy levels between a speaker and an audience.

5. Lack of Empathy – If you are a boss addressing your employees, are you measuring your remarks with how your words and body language and delivery are being viewed by those employees? If you are a physician delivering bad news to a sick patient, are you considering the news from the patient’s perspective? If not, you most certainly should.

6. Lack of Trust – Do you have a general openness about you? Do you maintain steady eye contact? Is your posture erect and confident? If you don’t believe in what you’re saying, rest assured your audience will notice. The trust will be gone. The message will be lost.

7. Lack of Reinforcement – Remember the old adage: Tell them what you’re going to tell them; tell them; tell them what you just told them. Give them the primary takeaway early, then reinforce.

8. Inappropriate Language – Choose your words carefully. Fit your words to your audience. Not too many, not too few. And be careful with profanity and other inappropriate language. It can greatly distract from your message to the point where it shuts down a listener.

9. Condescension – Do you enjoy being lectured to by a pompous jackass? Then don’t become one yourself.

10. Showing Anger – Keep your anger and aggravation in check. There may be the rare occasion where a strategic show of anger is effective, but in general it can reflect a lack of self-control or respect for the opinions of others.

Remember, there are several techniques for improving one’s communication abilities, but be aware of the foregoing as potential communication impediments.

Good luck and good communicating.
