Security Tips and Industry Musings
The most commonly used motion detector in alarm systems uses passive infra-red (PIR) sensors to detect movement. These sensor are sensitive to the surface temperature of the object in contrast to the background’s temperature. Some higher end motion detectors are dual technology devices. These devices add a microwave emitter to the PIR detector. The microwave emitter operates on the same principle as Doppler radar. Both sensors would have to indicate movement in order to go into alarm, thereby reducing false alarms.
Motion detectors are ideally used as “internal traps”. What this means is they are used as another layer of the security system in case the previous layer is penetrated. For instance if a window contact is bypassed, the motion will alert you as the intruder moves through the viewing area.
When deciding on the placement of motion detectors consideration for the way you live in the home, children and pets must all be taken on account. For instance, while a hallway is a great place for a motion detector to catch an intruder it is a difficult place to have one if your children may get up to get a glass of water in the night. Likewise if you have pets that you allow to roam the house, a motion detector may not be a good fit. With some thought there are compromise solutions available in most cases.
Smoke detectors, heat detectors, panic buttons and carbon monoxide detectors are some commonly used devices that contribute to the protection of the premises, while at the same time adding an essential layer to the safety of the people who live or work there. We will take a look at the variety of life safety devices in this installment.
Smoke detectors detect the presence of smoke in the atmosphere. When they have detected smoke they will cause the security system to alert the premises with an intermittent siren tone, while sending a signal to the monitoring center. Using atmospheric sampling makes the smoke detector able to read false positives under certain conditions. Dust, water vapor and aerosols are some contaminates that can create false alarms. Care should be taken to avoid areas that may make it easy for these to enter the smoke detector. Avoid areas next to bathrooms and air vents as well as non-air-conditioned spaces. Smoke detectors are the most useful in the air-conditioned spaces of the premises. It is recommended to have at least one monitored smoke detectors
per level of air-conditioned space. As most areas have an existing code requirement s for number and location of smoke detectors which must be met before occupancy is granted, these smoke detectors are largely of a secondary system in nature. As a secondary smoke detection system, the smoke detectors are placed in addition to the currently existing units.
Heat detectors are similar to smoke detectors except that they only detect the heat produced by a fire. Because of this they are typically used for spot detection in areas that a smoke detector would not be appropriate. As heat detectors do not use atmospheric sampling they are not affected by the same conditions that may cause false alarms in smoke detectors. Areas that should be considered for heat detectors are garages, near furnaces/ water heaters, rooms with fireplaces and kitchens.
Carbon monoxide (CO) detectors detect dangerous levels of CO gas in your home or works atmosphere. These devices have gained from rapid improvements over the years. When they were first introduced you could expect 1-2 years of service before they needed to be replaced. Today their life expectancy is rated at 5-7 years. It is recommended to have at least one CO detector on the premises.
Panic buttons allow the user to quickly alert the monitoring center to send the authorities when they are activated. Panic buttons can come in a wide variety of forms depending on the needs and uses of the client. Most commonly encountered are the three panic buttons included on the keypad. One for each of the emergency response agencies. Additionally, there are single alert type buttons. These buttons are set up at install to alert a pre-arranged agency. For older clients we may set up a key fob type button to call the medical services in case of a fall. While for a business we may setup a hard wired button under a counter to call the police in case of a robbery. The variety of panic buttons available allow us to tailor the system to the specific needs of the client and their expected risks.
Today, we have many methods for the security system to communicate with the monitoring center. The days of having to have a traditional land line from the telephone company are gone. It’s a field ripe with choices. I’ll touch on several of them and the pros and cons of each.
POTS- Plain Old Telephone Service, is a reliable form of communication. The POTS system allows voice transmissions through a direct wired point to point connection. The security system is connected to your existing home phones in a manner that will disable your phones temporarily in the event of an alarm condition that it needs to call out. After the communication is sent to the monitoring center, the phones will be restored for regular use. Some of the benefits of this system include no additional monitoring charges and reliable service. The drawbacks include the ease with which the service can disconnected (By a burglar or storm cutting the wires to the premises) and the need to insure that your security system is still functioning properly if ever there is service performed on your phone system.
VOIP- Voice Over Internet Protocol, is very similar to POTS system in the manner that they are connected to the security system. The major difference between POTS and VOIP is how the voice signal is transmitted. The VOIP system utilizes a portion of the bandwidth available from your internet service to send its signal. They are not recommended for security system use. There seems to be a wide gap in ability to use these systems for security systems between the different providers. The basic rule of thumb that we have seen is the old adage of you get what you pay for. The less the VOIP system costs the less likely it is to be able to transmit alarm signals reliably. These systems have the same limitations as a POTS system with the added problem of needing a battery backup to work in power outage conditions. Additionally, if you have service performed on your phone or data network it is possible to affect the security systems connectivity.
Internet Monitoring- Utilizes the current internet bandwidth to transmit signals to the central station for security system monitoring. It has the drawbacks of being easily defeated by cut wires or power outages (as in the above examples). The costs involved are similar to a primary cell system (below) because of the need to purchase an internet module and server time.
Cellular Monitoring- Also popularly known as wireless. A cellular system requires the purchase of a cell communicator that is designed to work with the security system. It is essentially a cell phone that is mounted with the control panel equipment. Like all cell phones there are airtime fees involved to keep the system active. The advantages are that they are completely independent of the other systems on the premises. They are not subject to cut wires and are connected to the security systems back up power supply in the event of a power outage. They do suffer, to a lesser degree, from some of the same issues as cell phones.
This is one of my first questions when talking with a prospective client. Many times there is some confusion on the client’s part of what they actually need. While we can’t cover every possible situation, here are the most frequent situations and how we proceed from there.
I do not have any security system. This is pretty straight forward, you need a new installation. One factor that will significantly affect the price is whether or not the premises is pre-wired.
Pre-wired premises have had the wiring for the security system already run throughout the home; usually at construction. It is rare to see a commercial space that was pre-wired. The pre-wiring usually dictates a lot of the characteristics of the security system. Example: location of motion detectors, master control panel, etc. Pre-wired systems are generally “trimmed out” at a substantial discount when compared to installing the same system from scratch.
I have a working security system on premises. This is the simplest service to perform. We come out and reprogram the existing system to call our monitoring center and make sure the system is in good working order. Proprietary or locked out panels may impact this. I’ll come back to this below.
My current security system is not working or its condition is unknown. This may require service and reprogramming to get it operational or to upgrade it altogether. It is difficult to forecast without seeing the individual system however, a good rule of thumb is if the system is eight years or older it is likely that it will need to be upgraded.
Proprietary systems are security systems that are designed to work with a specific security company only. They typically have their programming access restricted in one way or another. This restriction can be in the programming itself or require the need of a special programmer that is not generally available. Either way, the system will need to be upgraded.
Locked out panels are similar to proprietary systems in that their programming has been restricted however, they can be unlocked with the correct installer code (this would be supplied by the company that installed it.) thereby allowing the system to be reprogrammed. Proprietary and locked panels would require an upgrade to the security system.
Upgrading a security system involves replacing the control panel and the keypad(s). Most other devices on a system are universal regardless of the manufacturer or the proprietary nature and as a result, should not need to be replaced.
The brains of any security system is called the control panel (panel), or more universally, the motherboard. It can come in several different styles that we’ll go over later. As a rule, the control panel is the center of your security system. It determines the functions that you and your security company have available for programming. The specifications of a panel can be quite extensive. Generally speaking though, the average user will be a good fit for most of the panels available. The three most important considerations that we face with the average user is the number of zones available, the number of user codes available and the ability to upgrade the panel for future needs.
As I stated earlier in the series, the manufacturer of the panel really doesn't matter too much. As long as your choice stays inside the major manufacturers you will find this to be relatively true across the board. They all produce a high quality product. They all offer a wide variety of options. The difference for most applications usually comes down to the preference of the installation company. This preference is very similar to the age old Ford/ Chevy argument; personal preference.
There are two major panel styles available. Self-contained and the traditional panel.
The self-contained panel has all of its components inside one box that has the keypad on the front. They offer compact size (in comparison to the traditional panel) and ease of installation. While some of these of these offer hardwired zone connections, most current panels of this type do not. Most self-contained panels are designed to use wireless security equipment. Typically the only wiring necessary for these type panels is for the power supply and the communication connection if you are choosing a source other than cellular. These units are more expensive and due to the wireless nature of the systems are quicker to install.
The traditional panel arrangement consists of a circuit board that is contained inside of a metal box. This type of system typically offers a wider variety of options than the self-contained type. Most of these type control units are designed for use with a wired security system, adding a wireless receiver allows for the incorporation of wireless devices as necessary.
The self-contained units are a good fit for applications where the owner may move frequently. Their nature of installation makes them easy to remove and reinstall at the new location, often without the need of reprogramming. The more traditional panel is Atlanta Home Alarms recommended system for almost every other application. The additional time and lower cost allows for a more personalized installation.
The keypad is the standard user interface for your security system. It allows you to turn the system on and off as well as giving you access to system controls, such as assigning new user codes. Every system needs one. They come in many different variations.
LED or Icon displays are the lower end of the keypads available. Typically they display system information by lighting a led light or an icon that the user then needs to interpret. For instance, the “number 1” will illuminate to show that zone 1 is open.
Fixed displays are the most common these days. They display the system information from a fixed selection of words and numbers on an LCD screen. Zone violations are typically displayed as a number. These keypads do require a little interpretation on the part of the user.
The next step up in usability and price would be Custom displays. These keypads display the system information using a customizable list of words and numbers. For example, instead of the keypad displaying a “1” to mean that zone 1 is open, it would display “front door”. Many of the security systems higher functions require this type of keypad for them to be displayed. These keypads are typically a little more user friendly because of the way they display the information.
Touchscreen keypads have been available for several years now. They offer the flexibility of the custom keypad with a much cleaner look. Many of these kind of keypads offer the ability to act as an electronic picture frame as well. There is a pretty steep price climb to this keypad though. Touchscreens also allow some aspects of home automation to be utilized through one device.
How many keypads are needed? Generally speaking, it is best to have a system control on each floor of the premises. This allows for the most flexibility when using your security system. A typical installation would have one within reach of the entry door(s) and one in the master bedroom. Which leads us to the other forms of system controls available.
Key fobs are an inexpensive convenience item that can expand the usability of your security system considerably. They key fob is a small remote control for your security system that is limited to about a 50 feet range. It can be put on your keychain and used much like your cars remote fob. They typically have several buttons (we only install 4 button key fobs) Armed Away, Armed Stay, Disarm and a police Panic button. An interesting use that a customer of ours uses their key fob for is to allow the cleaning crew access to their home without giving them a code. They have a prearranged location to leave the key fob on cleaning day. On days the cleaning crew is not to have access to the home the key fob is moved from that location. Simple but effective.
Another control that is gaining in popularity is the smartphone app. It gives the convenience of the key fob, minus the Panic button. It also allows the user to see the systems event history. For instance, if you are at work you can see what time you kids get home from school. Smart phone apps also allow the user access through a standard web browser.
Whether you are currently in the market for a security system or simply need some additional information; I hope to provide you with enough information to get an idea of the different devices usages and capabilities. Armed with this information, you should be able to better assess your security system requirements and your specific needs.
Most of the information will be universal in its application. Security system manufacturers have similar products in terms of products and capabilities.
You can never truly compare an apple with an orange. Because many alarm companies essentially finance the installation costs with contracts and higher priced monitoring, home security systems are, just as hard to compare. Here are is a method to help you with the comparison.
Select the components you want in your security system. Once you have identified your needs, have all of the companies you are interested in quote exactly the same system. Different brands of equipment are fine. The components of the system need to be the same. Be sure to have companies include in their quotes the free items that other companies may include with the sale.
Note which of your prospective companies have contracts (and their term lengths) and which do not. Make note of any cancellation fees and if the system is leased or purchased outright.
Here’s the formula:
Cost of Equipment + Activation Costs + Labor + (Total Monthly Monitoring * Length of Contract) + Cancellation Fees = Total Cost of System
Once you have run each of the quotes through the formula a clearer picture will emerge. From there you will be able to make an educated decision.
Garages have evolved into an odd assortment of space. Consider yours for a moment. If you are like most people, it has become your main entrance, a large closet, odds and ends collection point, home for your pet and a general project workspace. I’m sure I left some uses out, but you get the idea. With that much going on there, think about what someone looking at your garage could tell about you. The first thing is, are you home? Do you have expensive items visible? Is the door cracked to allow air flow for your dog? By the way, this means Fido is not inside your home protecting it. A potential thief can tell a lot about you and your family by simply looking in your garage. There are some simple steps you can take to avoid giving too much information to the wrong person, and improving your home and families security overall.
To start with we should make it as hard as possible to see inside. Keep the garage door down as much as possible. If you have windows in the garage cover them so someone cannot see into it. There are several films that can easily (and cheaply) be applied to the windows to obstruct the view. Curtains or blinds work for this as well.
Overhead doors have some special considerations you need to think about. That cord hanging from the automatic door opener is a problem. Cut it off. It is possible to push the door from the top, reach in and pull that cord to release the door. Use the doors locks when you go on vacation. If your door doesn’t have locks (a lot of them don’t now days), you can attach a C-clamp to the rail right above a roller on both sides to block the doors travel.
The interior door should be as solid as your front door. Add a peep hole so you can see into the garage without entering.
Take a look at what you store there. The more expensive items should be out of sight from the street. Maybe move that tool chest to the back of the garage? Trash cans towards the front? The less conspicuous your belongings are the better.
Consider expanding your security system (or getting a security system) to cover the outer garage doors and windows. Low cost, no-contract alarm monitoring from Atlanta Home Alarm Systems can add lots of security for a small price.
While doing my morning read through of the news, I came across this article By Clark Howard in the AJC. Clark has some excellent points to consider before you make your security system purchase. While many of the ideas are fairly old fare for those of us that have followed Clark’s words of wisdom. It’s good to get a refresher and put it in front of people that may have missed it in the past. The last point is probably the most important. Do your security shopping before you need a system. Emotions run high after a break in. Many people overbuy when trying to secure their home after the fact.
Rereading this was good for me. It made me reexamine something that I already knew, and add my observations from my experiences from the other side of the sale. After years of selling security systems I have seen several points that most people overlook. Understanding your goals helps the representative you are going to meet best serve you.
Before you contact any companies for quotes, take a minute to understand what you want to do. Do you want to protect the Picasso’s in the living room or have additional piece of mind while on vacation. There can be a large cost difference between the levels of security.
Take stock of how your family lives in the home. Do the kids get up early while you sleep in on Saturday? If so, you may need several keypads or fewer motion detectors. Do you have pets that are given free roam of the house? Would you be alright with limiting their access while the alarm is on? Do you travel for work? Will this impact how you want to use the system? Maybe adding remote access and cameras is something you would like to do. These are some of the most common items we run across while working up an estimate for our clients.
Once you have done the first two steps, you are almost ready to start calling security companies. The last thing you should do is take stock of your home. Walk around the outside of the house. Are there points that look like good opportunities for burglars? How do you want to address them? Will adding physical barriers (more/better locks, stronger doors, less glass) solve the issue for you? If not, add that to the list to talk to the security company’s representative about. While you are walking around the outside, count the number of doors and windows you need to cover. This helps us be able to give you a ballpark estimate over the phone.
Now that your homework is complete, you are ready to start calling Companies. Friends’ referrals are a great source to start with. Call/email those companies and ask for a quote. One thing to keep in mind if you use email is to check your spam folder. (Many times I have responded to prospective clients, but have received an angry call the following week complaining that I haven’t responded yet; only for it to be found in the spam folder!) Most companies will insist on sending a representative out before quoting, some (like Atlanta Home Alarm) will be happy to give a quote based on what you tell them you need.
