First of all, our advice is to contact a specialist company because you are most likely not able to save money from this venture. But if you decide to go on your own after collecting information, you need to know the following.
To purchase an alarm system, you will first need to study which peripheral components (magnetic contacts, motion sensors or radar, crystal break detectors, smoke detection / gas leak detectors / water leakage sensors, infrared motion detectors, keyboards, sirens, remote controls and communication units, etc.) will be needed.
Then, you should choose the quality of the products you will use and the company that will supply them.
You will need to buy the tools you will need for installation.
Finally, you should study the programming and wiring instructions of the materials you have purchased so that you can put the system into operation.

To do the study you should act as if you were the burglar.
Take a walk around your house, your store or the space you want to protect.Note the possible points the thief could access such as windows, entrance doors, balcony doors, bathroom windows, staircase windows, garage doors etc. These potential violation points will have to be protected and to ensure their non-violation. Follow the instructions below for a proper and complete study.

Step 1
Determine in how many windows and doors you will place magnetic contacts to surround your area. You can also place beams around your area to detect a potential attacker before reaching the windows or doors. Specify the areas you want extra internal protection to place motion detectors. If you have a pet wandering in the room at night or day, it should affect the type of motion detectors you choose to install.

Step 2
Specify the possible position for the central control unit.Find the right place so it’s not easily accessible for everyone.

Step 3
Find the right place to place the keypad near the entrance door. It should be easily accessible so you can easily and quickly arm and disarm the alarm when entering or exiting your home.

Step 4
Once you have determined how many windows and doors and how many detectors or beams will be connected to the central control unit, you should select the central panel, which must be able to control all the zones in your home. Any window, door, detector or beam embedded in the system may be considered a zone. A basic alarm system usually contains eight zones. However, many alarms allow their extend to systems up to 32 or 96 or more zones.

Step 5
Be sure that the central alarm control unit you select can accept fire sensors, carbon monoxide sensors, gas detectors and water detectors. Additionally, make sure the panic buttons are included or can be included in the alarm system.

Step 6
Select a user-friendly alarm system. Confirm that entering the codes on the keyboard is not a complicated process and it is an action that each family member can learn quickly and use it comfortably.

Step 7
Specify the paths for placing the cables that connect the sensors to the control unit, which can be time-consuming and expensive process. The easiest solution is a wireless alarm system that does not need cables and is easy and quick to install. However, there are peculiarities for the wireless system, and its materials are clearly more expensive than wired.

Step 8
Decide if you want a alarm monitoring center service that will check your area 24 hours a day. However these services are checking your home for a monthly fee. An alternative solution is to place an auto diler in the alarm system that can connect to your phone line and in case of a violation of your home you can immediately notify by phone. And here it needs a careful study of what you gain and what you lose in any case.

Step 9
For proper system programming, consider your lifestyle. Some family members often get up in the middle of the night eg for a snack or a glass of water, so you should think about where you are moving during your stay at home. Your habits, such as the other members of your family habits should be taken into account in order to properly program the alarm system that will protect you.
