"It went great!  From Travis the sales person to Noah the installer I couldn't have asked for a more professional and through team to deliver my home security needs.  We just bought a new house in a neighborhood that's up and coming but there's still an element that we want to protect our home and valuable from.  Security One helped us find a system that we could monitor while we're away and that would make my girlfriend feel safe when I'm not a home.  We highly recommend them especially Travis and Noah.  Ask for them by name!

"About 4 years ago I need my home protected by something other than my dog while I was not home looking for a job. I needed something affordable, simple to use and install my self as my house was not prewired. I found Protect America and it had all I needed and more. Over the years I have added to my system more sensors, motion detectors, camera's, carbon monoxide sensor, and monitored smoke detectors. All of it was simple enough to do with some help with their Installation Technician walking me though everything on the phone. I have had other companies try to get me to switch to them, but what I have works and they could not beat the price so I told them no thanks."

"LOVE this system!  Customer service was extremely nice and made my experience effortless.  Speaking of effortless, the self-installation was super easy.  It took me less than 30 minutes from start to finish to get my system up and running.  Highly recommended!"

"First, I am a paid member and get unlimited services for a year. The
cost you pay for a years membership is nothing, compared to other
companies out there. If you want 24 X 7 available assistance not just
for your computer but visit their site and find out how many things
Geekatoo works on, you'll be surprised and pleased.
Youhave to down
load Team Viewer. You simply open chat box in Geekatoo, supply the
information from Team Viewer for the technician to remotely fix your
computer. You will also have to supply your Microsoft pass codeas well. 
Don't be concerned with giving out this information, as the technicians
are extremely professional.  I have had the service for about 6 months
and I have had them look at my computer at least 7 times. Not an issue
with Geekatoo.
The technician will communicate with you via chat
on Team Viewer. They will tell you when they are going to begin work.
All you do is walk away and let them work. Since Geekatoo is so thorough
the whole process will take at least 2 - 3 hours. You have sincere
professionals working on your computer to resolve your issues, not
someone looking at the clock and charging you $150 / hour.
Getting
a yearly membership is the most cost effective, but if you want to try
them out, you can pay for individual service. I think virus removal
would run you around $129  A years Green membership is $179.00  Plus you
get service for up to 3 devices at that price ! Services Included:
Computer Repair & Tech Support, Networking, WiFI and Internet,
Mobile, Smartphones and Tablets, TV and Audio (Except TV Mounting),
Smart Lock, Smart Home Hub, Sprinkler, Video Doorbell, Home Theater,
Device Help, Laptop, Printer, Router, Cell Phone, Wearable
Geekatoo
is the best money I've ever spent for computer repair. Many times the
technician has also called me at home to see if the computer is working,
and if there is anything else that they can do. How many companies
these days actually care about their customers ? It's common sense
business, with common sense technicians. What else could you ask for ?
Without hesitation, when my contract expires I will immediately re-new without hesitation.
Everyone
need their computer worked on from time to time. Why not have a proven
company, with 24 X 7 access for a reasonable fee be the on call computer
specialist for your worry-free on line experience? You're right, there
isn't any viable reason.
Geekatoo is my Geek to go to !

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Home Security Systems FAQs, answered by experts

A home security system can be a worthwhile investment for several reasons. Financially, it may qualify you for a discount of up to 20% on your home insurance premiums, which can help offset the initial setup costs and any ongoing monitoring or subscription fees. For many, the primary benefit is the peace of mind that comes with enhanced security, especially for those living in areas with higher crime rates. Ultimately, whether a system is worth it depends on your personal preferences, the value of the assets you wish to protect, and your overall safety concerns.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

Understanding the pros and cons of installing a home security system is the first step to deciding which one is right for you. A few of the advantages and disadvantages include:

Pros

  • Added security for your household

  • Reduced home insurance premiums

  • Many smart home integrations available

  • Security companies can monitor your home 

Cons

  • Expensive setup costs 

  • Subscription costs can add up quickly

  • Features may be vulnerable to hackers

  • Weak signal reduces the security of a wireless system

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

You likely can reset your house alarm without the code, but it depends on many factors like how it’s wired and whether or not there’s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. 

But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.
