What makes a security system

The good the bad and the Ugly

The starting point of any security system good or bad is the main control panel, sometimes referred to as “the brains”. When it comes down to it, the majority of security systems on the market today are similar. Differences lie in whether the system is hardwired, wireless or hybrid (wireless / hardwire combo) as well as the various advanced features.

Without getting into too much detail, having worked with both wireless and hardwire systems, I will always choose hardwired over wireless hands-down. For more information on the differences between hardwire and wireless security alarm systems, see the truth about wireless security systems.

While many people will decide on a security system based on advanced features, it is important to consider all those using the system both now and in the future. In saying that, I am by no means suggesting you stay away from the advanced features. In fact I believe in choosing a system which will cover all possible preferences and requirements. Typically I recommend systems which are modular in design with room for future expansion.

Systems designed around a communication bus with a large selection of modules are the best way to go. If the manufacturer is up on the latest features within the security alarm industry you will be sure to have a system which will outlast the typical toilet alarm by decades. For my installations, I prefer a Canadian manufacturer by the name of Paradox. They have a large selection of modules ranging from zone expanders, relay modules, wireless arm/disarm, Remote telephone access, TCIP & direct connect PC modules. With a highly competitive price point, Paradox systems are suitable for all sizes of installations from small one bedroom condo’s and retail outlets to large mansions and industrial complexes.

Having covered the control panel, the effectiveness of any security system, regardless of complexity is largely controlled by the quality of the installation. In fact, choosing the right installation company is often more important than the choice of a control panel. Many factors go into the proper installation of a security system; these can range from the ability to conceal wires, choice of detectors, installation standards as well as quality of after installation service.

It has become increasingly difficult to find quality installers who take pride in the quality of their installations. For that reason, many alarm companies are opting for the easier to install wireless security systems. Unfortunately this leaves the customer with a security system which could result in a lifetime of problems. Whereas a properly installed hardwired security system will out last and outperform pretty much any wireless security system on the market.


When looking at installation standards, it is often difficult to tell whether a company is really as good as they say they are. Of course no company will tell you their installers are lazy and have sub-standard installation practices. One way to determine the accuracy of their sales pitch is to ask to see samples of their work. Although not much can be seen from a picture of the wiring in a control panel, a general idea of pride can be determined. A messy wiring job in the control panel is often the sign of poor standards in the field. Important factors in the proper installation of a security alarm system are the splices at the contacts, proximity of electric interference to alarm wires, and quality of detectors used.

The most common issue when it comes to poorly installed hardwire security systems is the splice. If done properly, there should be no issue for as long as the system lasts. If your security system door contact is false alarming, typically this would be as a result of a bad splice. Other causes of door false alarms include mis-aligned magnets (Also a result of poor installation standards) as well as contact failure. Contacts also tend to fail if the wood frame around them expands and crushes the glass tube containing the magnetic switch.

With alarm panels becoming more and more sophisticated, electrical interference can be a source of headaches for both hardwire and wireless security systems. More prevalent in wireless security systems, Electrical interference can happen in hardwire security systems as a result or improperly run wiring. For example, a keypad wire run along a large length of high voltage wire can result in false signals being generated or the keypad not functioning properly. Although many modern control panels allow for electrical filtering, it is always a good idea to follow the electrical code when in comes to low voltage wiring and their proximity to AC lines.

Although more on a managerial level, the choice or detectors is a very important aspect of the reliability of a security system. After all, the ability of a security system to properly detect an intruder is largely controlled by the detector itself. For more information on the types of detectors, see False Alarm info.

As you can see, the choice in the alarm company you decide to trust with your security should be based on more than just who has the best ad campaign. Although determining the installation standards of a company can often be difficult, it does help to talk to friends and neighbours. Also, ask to see photographs of their work, most companies who do not take pride in their work will not keep photographs. Look for proof behind the marketing words.
