the alarm system codes are the same and the reason a License for alarm system installation is required in most states is because you need to know what you are doing and how, more if this is for save life’s or keep the bad people outside your properties. A local security company will give you a better understanding of what you need, the extra $200 you may pay with a security copany is value if they are the ones who will handle you a 1 year warranty and if you have any issue after that they will be there. Keep in mind the license is because the F. B. I check background and they pass the state test to be installers. You hqve a good point here. For security cameras yes anyone can do it. For alarm systems where is involved
lives, I am 100% people we love to know every thing works fine and it will be working agter is installed it, also people forgot the liability point of view of insurance. If you install by your self a new set of brakes
in your vehicle to save some dollars and you got an accident and the accident was on investigations and show at the end it was because you forget to place the safetu device and the insurance found this issue and ask where you do your breaks so we can go and claim every thing we are paying to you…you will say, I did it by my self. Where you thing the investigations and suspicious will go. More and more people install alarms system by it self and more and more you see them in courts defendant their self from insurance claim they did it in porpuse, insurance think they did that wrong to claim millions.
