"I responded to a flyer that I received from ADT as I had been thinking  about installing a security system for extra peace of mind as I am a single woman living alone.  It sounded like a deal that was too good to pass up.  I did not realize until I did some research later that ADT subcontracts all of their installation out to local providers so I am not sure which parts of this review should be directed at ADT vs Protect your Home...who provided the installation service but it is clear that their business practices have  common core and most of my interaction has been with Protect Your Home.  Apparently, after 3 months Protect your Home is no longer responsible for my system and after some research I am starting to wonder what will happen when ADT becomes responsible for addressing any issues with my system if there is no local service provider.
Here's an overview of my experience. It was easy to set up the appointment and the installers arrived right on time.  I want to state that my low grade has nothing to do with my overall experience with the installers who came out and installed my system.  They were friendly and courteous and very professional in completing the install. Nor am I dissatisfied (for the most part) with the system that has been installed. However, the reason that I would not recommend Protect your Home is that I  do have a problem with the sales tactics that they use which I have to believe come via ADT and then through the local installer Protect Your Home.  I was definitely oversold and my monthly premium is too high and much higher than I was initially quoted.  I am also locked in for 3 years which is  too long and should be unnecessary if your product is worth the cost. I believe there are better ways to set up business practices so that your salespeople are not so dependent on the commission they receive from a sale.
After evaluating my home my installer did some neat number tricks (this is sarcasm) to give me an estimate that was supposed to convince me that getting the highest upgrade was actually going to be the best deal for me after all of the credits had been applied.  I didn't really buy it but at that point I didn't completely understand all the components and the implications.  I was also prepared to invest in a security system and could also see the value in most of the parts of the system.  I ended up agreeing and the installation was completed that night.  I'm not sure what would have happened if I had asked to think about my options...my installer was a smooth talker and knew how to take advantage of me as a single woman.  Over the next few days as I reviewed the contract and started using my system I realized that I did not need the security camera or the supposedly handy clicker for disarming and arming the system that was supposed to be a bonus but was listed at $150 on my invoice.   The clicker is pretty much useless if you go with the Pulse system and can control the entire system from your iPhone. I also thought my monthly premium was higher than it should be.  I called ADT to inquire and the rep told me that I could return any equipment for a refund for 30 days.  I was also quoted a monthly rate that was lower if the camera was returned.  They set up an appointment for my installer to come out to collect the equipment that I did not want.   However, when the installer came back out he contradicted the information that I had received from ADT.  At that point I didn't argue and didn't want to deal with the frustration of navigating between all these parties so I kept my camera, my unused clicker, and have a higher monthly premium than I believe I should have.
As a customer I would be much more likely to recommend this company if you set up your practice so that your salespeople came out for an initial evaluation and clearly explained the options and pricing. THEN, gave the customer time to consider the options and choose the system that best suits their needs.  Yes, it takes more time but now that I have done some additional research I understand from first hand experience why ADT has lost credibility to other home security providers.  Until this changes I would recommend that anyone looking for home security system do their research before setting up an appointment with ADT based on their name value alone.
Finally, I also have yet to receive my $100 VISA gift card which required extra hoops to jump through in order to have it sent out.  I sincerely hope that both companies consider their business practices and make some changes or I definitely be considering another company when I move and/or at the end of my contract."

"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!"

Home Security Systems FAQs, answered by experts

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.

A study from the University of North Carolina found that security system signs were one of the top ten deterrents for burglars when choosing a target, so they do have some effect. However, you can get into legal trouble for putting up fake signage, so it’s best only to put up signs when you have the alarms to back them up.

The cost of home automation averages around $1,000, with most projects falling between $200 and $2,000. The total cost depends on several factors, including the level of automation, brand, system features, home size, and location. For a DIY approach, basic home automation technology can cost between $100 and $500, though the scope and interaction between products may be limited. High-end, all-inclusive systems for larger homes can cost anywhere from $10,000 to $150,000, especially when they include smart appliances like refrigerators and dishwashers that require extensive wiring. Additional costs, such as subscriptions for maintenance services, can also impact the total price. It's often helpful to set a budget and consult with an expert to determine the best options for your home.

Although some pet doors allow easier access for burglars or stray animals, there are ways to make pet doors more secure. To increase your home’s security, choose locking or electronically activated doors, use additional motion sensor security cameras, and install pet doors on a wall where door locking mechanisms are difficult to access.
