CSI SECURITY REVIEWS

This was a wonderful company to work with, they helped me out alot with one of the assisted living facilities. I want to thank George for being a huge help, not only was he great at communication but also came to the facility at no cost for a walk through to help us figure out what we needed. Thank you George for being kind and patient we appreciate everything you've done for us! You can definitely trust this company to help you with your needs.

CSI was just great!! I interviewed all the local companies large and small. They were the best; big enough to provide everything I needed but small enough to be very personalized service. They have been out numerous times to adjust/modify as necessary and really wonderful to work with. Thank you.

I am an estate manager for a prominent family in Santa Monica. We switched to CSI Security five years ago and have had no complaints since. The staff is very forthcoming and helpful when any situation arises. Whenever the occasional problem happens, they send a technician as soon as possible, which is usually same day. Some of their staff members, Al, Greg, and David have gone above and beyond when consulted for aid. We highly recommend CSI Security.

POWERCCTV REVIEWS

The security camera system at our home was not working properly and a couple of cameras were not displaying a clear picture. We called Edgar about this concern, and he was able to provide us with an estimate and resolved the issue the following day. We are very pleased with the results. Edgar's quality of work reflects extensive experience in his profession. We will definitely seek his services should we experience any future concerns or if we upgrade our current system. Thank you, Edgar, for a job well done!!!.

Excellent service from PowerCCTV. Edgar is truly a professional and meets all our security camera needs. He's been taking care of us for 8 yrs. He's always responsive, courteous and professional. Thank you.

Frank is an awesome Chapin , worked with me on getting my cameras back online , Great Job Frank!!.

ACS SECURITY REVIEWS

I’ve had such great service from ACS. The repair guy Steve has been on time and so knowledgeable on my old system. He’s a really nice guy too. He’s been here a few times in the last few years and always professional and cheery. They are quick to respond when I had an activation and when it’s been a troubleshooting problem, they find out why.

Fantastic experience with ACS! Chris diligently guided us through our best security options. Gellert & his assistant did a terrific!! job installing everything, as well as walking us through the logistics of using the system. The technology part was very easy to implement. I highly recommend ACS.

Ray, the ACS rep who provided the service was excellent. He was here about two years ago and knows our system very well and efficiently put it back into working order in less than an hour. Arranging for the appointment was easy and the confirmation was much appreciated.
