No, this site only provides information about home security systems.
If you have a system that needs immediate service, search for a local security company. Using Google or your favorite search engine, try entering “security systems service”, followed by your zip code.
If you are looking for an alarm company to install a system, you can get free home security systems quotes from companies in your area. There is no obligation to buy anything, and no credit card information is needed. Getting these free quotes will give you a good idea of what it would cost to have a system installed, as well as how much you could save by doing it yourself.
Much like a car, an appliance, or any other product, the “best” security system is one that fits your needs, based on cost, ease of use, and your security comfort level.
A cheap alarm system that doesn’t make you feel safe and secure isn’t really worth even the “cheap” price. Likewise, a high-end system that you can't afford, is difficult for you to operate, or that you don’t trust won’t help you much either.
Each person or family has their own security “needs”, and good alarm professionals have learned to match those needs to the best home alarm that’s useful and affordable.

Alarm system costs can vary widely, depending on what you’re looking for.
In simple terms, you can have a basic system installed for free or nearly free, provided you’re willing to sign up for alarm monitoring for a year or more.
If you don’t want to commit to a monitoring contract, you can pay for a security system outright. Basic systems for a 3-bdrm/2-bath home might consist of a main control panel, a keypad or two, a motion detector, and several door and window contacts. Depending on where you live, this may run from a few hundred dollars to over a thousand.

One of the best ways to get an idea of what a system would cost is to get a few free home security systems quotes from companies in your area. Just answer a few questions about the type of system you would like, and you'll receive free quotes via email. Best of all, it's free!
There really is no catch, as long as you understand what you’re paying for.
It all boils down to a trade-off between equipment and labor costs versus monthly payments for alarm system monitoring. If you commit to monitoring, you can get a free or nearly free system. Decide not to take on the monthly monitoring cost, and you’ll pay up front for the equipment and labor charges.
Which way to go depends mainly on your situation and preference. Many people find it easy to pay monthly over 2 or 3 years, in order to get a complete home security system installed. Others don’t want to be tied down to one alarm company, and choose instead to pay for a system outright.
In most cases, no. Most people don't like the inconveniences that go along with "bugging" the overhead door. Long exit and entry delay times must be programmed, to allow you time to move the vehicle in and out.
I often recommend a twist on this idea: Connect the garage overhead door to the alarm, but program it to display status only. This will give you a visual indication that the garage door is either open or closed, but it won't trigger alarms or cause entry and exit problems.

Small dogs are sometimes not seen by many motion detectors, while larger dogs are;
Cats are often more active than dogs and tend to climb, making them more likely to set of motion detectors;
Pet immune motion detectors are available, and most work well. They do require proper positioning and adjustment to make sure they aren't tripped by the animals.
Check out this page on How to Run Motion Detector Wiring. It gives some good details on what's involved in setting up a security system that will accommodate your pets.
Many cities and towns do require you to have an alarm permit, even for DIY and non-monitored systems. Alarm permit fees are usually charged annually, and they help offset the expenses caused by false alarms.
If the police respond to an alarm from your system and you don't have a permit, you could be fined.
Check with the police department or an alarm professional for information on alarm regulations in your area.
Brinks has been out of the safe and alarm equipment business for many years, and I know of no reliable source for safe keys or combinations.
If the safe contains valuables, you can contact a local locksmith for help getting it open. They may even be able to cut a key for it, although replacing the safe may be a smarter choice if it is very old and has a lot of wear.
Brinks Security was bought out several years ago by Broadview Security, which was in turn bought out by ADT shortly afterward. If you have one of these systems, your best option will usually be to replace the system.
In some cases, you can keep your older Brinks system running a while longer.

If your system is monitored by an alarm company, call the 24-hour service phone
number and/or the central station for instructions.
If your system isn’t monitored or you don’t currently have a security company to do service, check the alarm system keypads. The display should indicate what the problem is. (You may need to consult your alarm user manual to pinpoint the cause.)
Depending on your situation, see these pages for details on what to do:
For general help, see My Alarm Keeps Beeping - What Can I Do?

For DSC systems, see My DSC Home Alarm is Beeping! -Causes and Solutions.
For ”Low batt” or alarm low battery, see

For ”Fire”, see How to Stop a Beeping Smoke Alarm.
”FC”, “fail to communicate”, or “Comm fail”: This usually means the security panel has lost its connection to a phone line, and can’t send signals to the central station. Check for dial tone in the house phones, and check phone wiring to the alarm panel.
As a last resort, you may have to completely shut down a system that won't reset or respond to keypad commands.
I get this question a lot, and unfortunately there is no easy answer. I don't know of any source for keys alone; most sources only sell the alarm cabinet locks and keys as a set. You can try searching for keys by your alarm panel brand name on Amazon and eBay.
Here are a couple of other things to try:
If you can't find a key, you can always pay a local alarm company to open the box, since most technicians have keys for the most common brands. They can then sell you a replacement lock and key set (or they might sell or even give you a key.)
As a last resort, you can either drill out the lock, or pry the lid open with a heavy screwdriver. Not very subtle options, I know! Once the can is open, you can either re-secure it using just a screw, or buy a replacement lock set.
Absolutely! There are more choices available for DIY home security systems now than ever before.
Labor is the single biggest cost of an alarm system, so doing it yourself can be a big money saver. If you’re reasonably handy and are able to use basic tools like wire strippers, screwdrivers, and a drill, a DIY security system may be the perfect choice for you!

Perimeter wiring should include all doors and movable windows that lead to the outside of the home. Add any areas where you'd like more security, like garage overhead doors, detached workshop or storage shed, gates, etc.
Interior wiring primarily includes motion detectors and glassbreak sensors. Also run wires to any areas of special concern:
System wiring includes everything the alarm panel needs to operate:
Fire alarm wiring for smoke alarms, heat detectors, carbon monoxide (CO) detectors, etc.
For more information, see these pages:
For doors and windows, use either 2-conductor or 4-conductor, 22 AWG (22 Gauge) wire. Also referred to as "22/2" and "22/4" for short.
For keypads, motion and glassbreak detectors, and other powered devices, use 22/4.
For smoke detectors and heat detectors, use fire rated 22/2 or 22/4, depending on the device. Heavier 18 gauge fire wire, AKA 18/2 and 18/4 can also be used, and are often easier to find.
For telephone line connections, any type of wire designated for phone use will work.
For more details, see:
When an alarm system doesn't seem to be responding to programming changes, there are a couple of common causes.
Multiple parameters must be specified for several functions, including test timers and zone definitions. For example, to send a test report, most systems will need you to specify:
In addition, some systems have a location to turn the test timer off or on. If any of the parameters aren't programmed, the test signal is never sent.
Rebooting is required for certain programming changes to take effect. If you make a programming change that the system doesn't seem to respond to, try powering the system off, then on. This requirement for a reboot is often documented in programming manuals, but not always.
This is one of the first things that the average homeowner should
consider doing on their own. If you’re not currently
under contract or monitored by an alarm company, any outside company you
call will have to charge you for the battery and a service fee.
If you are contracted with a home security company, check with them first. Some companies include certain services in their alarm agreements, so you may get service at a discounted rate.
For details on what’s involved , see this page on alarm system battery changes.
The battery in the main panel should last about 3-5 years. This can vary depending on conditions.
High temperatures are not good for batteries, so I always prefer to locate the main panel in an air conditioned room of the house.
This isn't always possible, due to floor plan and construction details. Panels installed in hot locations will likely need more frequent battery changes, possibly every 2-4 years or so.
Loose or missing magnets
Surface-mount magnets often come loose when the adhesive backing dries out and loses its grip. You can simply re-attach them by following these steps:
contacts will eventually wear out and need to be replaced. You can save
money by replacing faulty door and window contacts yourself.
If you’re with a company, check with your alarm representative before doing any work on the system.
If you don’t currently have a security company servicing your system, check out these pages to see if you might want to try the repair yourself:

Neither is type is “better”, but one may be better suited to your situation than the other.
Generally, hardwired home security systems are better for new construction, or in existing homes with attic or other crawlspace to run wiring. Wireless home alarm systems are the best (and often only) choice for existing homes without crawl spaces for running wires.
If you have the option to use either type, get estimates on both kinds. Then, weigh the cost versus benefits of each system. While hardwiring is more reliable than the radio signals used in wireless systems, it may not be worth the expense to add the wiring.
home security systems consist of cameras and at least one monitor, to
view the activity. Today, a home security system video setup will
usually include a DVR (Digital Video Recorder) to record activity.
Recorded video can be viewed later, or burned onto a disc for use by
police or other authorities.
Live and recorded video can also be viewed remotely, using a network enabled DVR. This allows you to watch camera footage from a PC, Mac, or laptop. Lately, many products enable viewing video surveillance on smartphones as well.
