Burglar Alarms are electronic alarms designed to alert the user to a specific danger. Sensors are connected to a control unit via low-voltage wiring or a narrowband RF signal which is used to interact with a response device. The most common security sensors are used to indicate the opening of a door or window or detect motion via passive infrared.
New construction systems are predominately hardwired for economy. Retrofit installations often use wireless systems for a faster, more economical installation. Some systems serve a single purpose of burglar or fire protection. Combination systems provide both fire and intrusion protection. Systems range from small, self-contained noisemakers, to complicated, multi-zoned systems with color-coded computer monitor outputs.
Video Surveillance helps you to keep an eye on what’s most important to you whether you are in the home or not. A home security system is a great start to protecting your home, family, and property, but a video surveillance system gives the added protection of allowing you to see exactly who’s in or around your house at all times, often even remotely from a web-enabled computer, your PDA, or even your cell phone.
The Panel is the metal box that holds the circuit board of the actual alarm system, along with the back-up battery that powers your alarm during a power outage. In a standard installation, this devise is installed in the basement, usually somewhere near the circuit panel and telephone demarcation point (where the telephone line first enters your home). In an apartment or condo, it may be installed in a closet or above a drop ceiling. Be sure your panel is installed in an area where it cannot easily be tampered with.
Line Seizure – Your alarm system must have priority access to your phone line, above all telephones, internet modems, answering machines, etc. Line seizure simply means that your alarm panel will disconnect these secondary devices if the alarm needs to send a signal to the central monitoring station.
Installer Code – Your alarm can be armed and disarmed with a standard (usually four digit) user code. Your master code is a step above a regular user code. It can also be used to turn the alarm on and off, as well as programming or erasing a regular user code. You can also use your master code to bypass certain devices. The installer code is the most important, it gives your alarm technician access to program your system during installation e.g. what type of device is being installed to each zone, entry/exit delay, telephone number of the monitoring station, etc. Most alarm companies use the same installer code for all of their installations, and the vast majority will never give their installer code to a customer, for obvious reasons.
Keypad is the device you use to enter your code to arm or disarm the system and to see which device caused an alarm. Your installer will use the keypad extensively to program your alarm. The keypad is much different to the similar sounding ‘control panel’ discussed above.
