There are so many alarm system choices on the market today and it may be difficult to discern what features your home really needs.
First time buyers can get confused, frustrated and even talked into a system that goes above and beyond what they really need.
Outlined below are bare bone features that all home security systems should include.
Installation Wiring - Should your system be wired or wireless? The major decision in deciding this factor should be the type of construction your home has and whether or not your location is wiring friendly (meaning extensive labor costs might be involved).
With wireless systems, consider whether the wireless devices you are using can communicate with the main alarm box.
Thick plaster walls that consist of any interior metal can sometimes block frequency signals.
Believe it or not, every door and window in your home does not need to be hard wired into your main alarm system.
If you're on a tight budget, single area access points can be protected with inexpensive wireless alarms and sensors at a later date.
Hard wired or wireless, make sure the system you purchase meets your expectations and can provide you with future expansion if need be.

• Panic Buttons - Every alarm system should include panic buttons that allow the homeowner the ability to alert authorities such as fire, Police and emergency medical services.
  
• Interior or Exterior Motion Detection - Alarm systems at the very least should include some kind of interior or exterior perimeter protection that allows movement to set off the system or trigger the alarm.
  
• 2-Way Calling Features - Your home security systems main panel should be wired to allow for two-way calling with your responder company.
  Generally, this usually means if the alarm is triggered, you'll be put directly through to your responder so they can check in with you and you can instantly report a false alarm or send the corresponding emergency services such as fire, medical or police.
  A 2-Way audible voice system is always a good idea for people who are disabled, elderly, or living with someone who is.
  A 2-Way Voice feature allows you to talk and respond from up to 75 feet away.
  
• Panel lights and audible alert indicators - Generally, most systems should always have backlit panel lights and alert indicators to let the homeowner know when the system is armed or disarmed.
  Panel lights allow for better visibility at night when entering pin codes and audible alerts are even better for the elderly who sometimes need verbal confirmation that the system is "On" or Off".
  
• Digital Entry Keypad- Alarm systems require a main control panel or keypad that allows the homeowner to enter their security codes when entering or exiting the house.
  Digital keypads should be positioned properly and installed in an appropriate place that allows for easy and convenient use.
  

The above basic key features will ensure that you have the best access to your home security systems responder and provide a more convenient alarm system that will meet all of your needs.
