"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"Good price. Typical monitoring services. My only real issue is that most of their account servicing needs to be done via snail mail or over the phone--they do not have a website to update contact info, billing info, or other details."

"Frontpoint is very easy to use... it's one of the only DIY services out there. You can install all the sensors yourself (they are all wireless). You stick them where they need to go with very clear instructions, and if you do need help Frontpoint support is excellent. You always get someone on the phone, and they are always happy to walk you through any issues you're having. I've had issues a few different times with dead batteries in a sensor, or misplacement of a sensor causing issues, and in all cases they've resolved the issues quickly over the phone. Because of this, I can manage the system myself (and that's pretty much installation upfront, updating equipment every few years/as needed, and support very rarely). We've yet to have a breakin or anything like that, but we've had several false alarms where my wife accidentally set the alarm off... and in those cases, Frontpoint calls you immediately, asks you for a password, and then asks if you need assistance. Of course we don't, but if they can't reach you... which has also happened... they call the next person on the list (my wife). If they can't reach that person, the cops are already on their way while Frontpoint works down the list of family members, neighbors, etc. to let them know there is an incident at the house and the cops are on their way. This has happened a couple times (due to user error). But it's good to know they have our backs if there is ever a real issue. A+ for Frontpoint."

"The service provided by CSI Secure Solutions was second to none. From the start the team was professional, diligent and tenacious in their quest for answers. This was not an easy case but Chris and his team went above and beyond the call of duty. If you are looking for a quality investigator with integrity, compassion and skill, I highly recommend CSI Secure Solutions."

"It was a long process and very involved as the routine Windows Update process did not work and required a work-around to get to the latest version of Windows 10. Things that should have worked didn't but Robert hung in there and made sure the update did get done and that my system was properly set for security as well. Kudos to AIO Integrations LLC and to Robert specifically. I'll certainly be using their services again, without a doubt. When ya find someone that does a great job, ya stick with them!"

"After researching online about Safe and Sound Security and Monitronics made an appointment with Brian Jaime to meet at 6pm. Brain was on time for the appointment and very professional. Brian was polite, respectful, not pushy, transparent, and explained the packages and what is best suited for our home. He was a good listener too which something you may not see in some of the business developers. I know instead of calling Brian a sales person I called him a Business developer this is because a sales man or woman is only interested in selling his product for a certain price and bad mouths other competition. When I mentioned to Brian that I have been talking to other outfits, he explained the difference in service and methods of business operation between them and the others. His first point was all about quality. Safe and Sound located out of Walnut Creek has been the #1 dealer in quality aspect for the last 5 years. This impressed the heck out of me as myself  working in a big Corporation where we internally compete every year to bag the top spot in quality and I will tell you that is not easy. Therefore with him defining what he and his team brings and the value of it from others definitely made him get my contract.



I signed into their standard 3 year contract for a reasonable price for the package I got. I am writing this review at this time and giving Safe and Sound Security 5 stars for their professional approach towards developing their business, transparency, quality, genuine interest towards their customers.  



They are a local outfit and the way this outfit works is, the contract, equipment installation, maintenance, and any trouble shoot calls will be handled by Safe and Sound Security team in house. you call their local customer support number during normal business hours of Mon - Sat 8 am to 9 pm and on other hours the call is answered by Monitronics and a ticket is issued and forwarded to Safe and Sound for action. you can call and if you are local you can walk into their office to request service. Being local is a plus for me. Monitronics renders 24/7 monitoring support. However, your contract is with Safe and Sound security.



Safe and Sound have been around for 8 years and to bag 5 years of #1 spot in quality service is great achievement and I expect that same service moving forward :) So far my experience has been great, have scheduled installation with tech today. will update my review with the installation experience and my future experience with this team
