As per reviews, I was very satisfied with the entire process. I recently purchased a home that already had ADT installed, which is why I initially wanted to stay with ADT. After that decision, finding who would install made the next most sense.  They didn't try to make me purchase anything I didn't need, they were straightforward with what were "add ons" versus just basic service, and their installation with quick, seamless, and very professional. On the sales side I worked with [Kyle](https://www.californiasecuritypro.com/ADT-California/ADT0San-Ramon/Kyle-Madison), on install I believe his name was Ray, and again, the entire process was great.  I ended up adding 7 (one was thrown in to make sure my son's room was completely covered since it has a door and windows to the outside) more sensors and 1 motion detector. I also added the ADT Pulse app to my plan (it allows you to arm and disarm from an app, along with other features) - [D S.](https://www.yelp.com/user_details?userid=Td8llceu52-QSjthjArNew), **Lafayette, CA**   **----------**   1/20/16![describe the image](https://www.californiasecuritypro.com/Portals/137046/images/yelp_stars1.gif) #### **"I've had no issues over a year later."** Fish Araya from California Security Pro was very friendly, responsive and helpful with my home security installation.  The security system has been working well and I've had no issues  Over a year later, I asked [Fish](https://www.californiasecuritypro.com/adt-san-francisco/California/Fish-Araya) a technical question about the system and he was again very helpful.  Would recommend this system to my neighbors and friends.

Justin was the salesman who came out. He was very attentive, listened carefully to our needs and concerns and provided some great recommendations. He even gave us tips on things that we could do on our own to make our home even safer. He was very patient when we told him we were stil shopping around and invited us to call him at anytime and he'd come back out at our convenience. After talking to other alarm companies, we felt ADT offered the best equipment for our needs. True to his word, Justin came back to our home the same day that we called him back, finalized everything and arranged for installation the very next day. Rene was our installer and was also great. There was a minor glitch in the installation, but Rene came out the next day and quickly fixed it. We've had the system for a week and it's working great. Everyone we dealt with at California Security Pros was very professional, knowledgeable and attentive to our needs.
