We've sent them feedback emails…read moreevery time the system failed and they said they'll review and recover but no improvements over the years. The main issue is the person who's watching the intrusion is either not reacting when a thief coming (like literally 20 sec to 2 minutes of full inaction), or they incoherently saying "this is deep sentinel" - like it's suppose to do anything and it doesn't. When they did react (always late), they haven't called the cops not a single time when we had intrusion on our private property (a guy tried to open our garage door at night, another person was stealing stuff from a trash bin right next to the entrance door at night). When it was obvious theif stealing amazon packages from the porch, the DS guiard after watching it for 20 seconds, introduced herself and wished him a good day (facepalm). On a search to replace this joke.

I recently decided to upgrade my security system since technology has come a long way in 10 years…read more California Security Cameras did the upgrade for me and the entire experience was exceptional from start to finish. A quality security system is truly invaluable when you consider the peace of mind it brings, and this is a company you can absolutely trust. The process began with excellent communication from the office before any work was even scheduled; they provided quotes in a timely manner that were easy to understand and fit perfectly within my budget. What impressed me most was that they use only quality equipment, and Israel took the time to review both what I needed and what I didn't need, which was equally important to me. Israel and his team can be counted on to show up right on schedule and complete the work in a timely manner. The installation itself is top-quality, with a lot of care going into strategic placement to ensure total coverage. Before any work started, Israel walked through the property with me and openly listened to my needs before deciding on the final camera placements. Additionally, they are respectful of your home and animals while working. they take care to close gates and doors when coming in and out which was important to me. Once the installation was complete, he tested the entire system, ensured all cameras were adjusted properly, and then personally went over how to use the system. I'm the type of person who asks a lot of questions about projects before, during, and after, and Israel and his team made sure that I fully understood everything before wrapping things up. If you are looking for a professional, reliable security team, I highly recommend California Security Cameras!

The cost for a new system was in the thousands. I called a computer repair company in Walnut Creek.

Cost of the industrial quality CCTV HD (4 times larger capacity than the original HD) was $150.00!!! Works great !!!

Wow. Dan just came in and did some incredible and detailed work at our single family home to help…read morelevel up the wifi speed with two Cat6 ethernet cables - one to the living room and one into the abyss that was my garage (where I work.) When he came, he did a thorough assessment of our options based on what we had available (checked the attic in our main home and our garage attic), provided me a quote, and got the work done in two hours. He even pointed out some items in our attic that might need attention (a weak beam), and even engaged in some friendly conversation with my two year old that was wondering "What's he doing?" every 5 minutes. (Sorry if that slowed you down, Dan.) Bottom line: Dan's approach is genuine and authentic, and we highly recommend. The Saturday visit was not expected, but I'm actually looking forward to working on Monday. Thanks, Dan!

Not only did he do an exceptionally clean and professional job with the cabling, but he also provided some great, logical suggestions to optimize the setup. What really sets Dan apart is his willingness to go above and beyond. He didn't just stop at his assigned task; he troubleshot and connected an exterior cable that Xfinity should have handled in the first place, ensuring my internet was fully up and running before he left. I truly appreciate his expertise and work ethic. I wouldn't hesitate to work with him again in the future. Highly recommended!

Mike and his team were absolutely incredible from start to finish while installing my full home NVR system. Suntech stands out above the rest with their unparalleled technical expertise and exceptional value for the quality delivered. When choosing a company for something as important as your family's safety, it's crucial to pick one that really understands the technology inside and out and how to optimally utilize it to secure your home. During my consultations with various security companies, I kept going back to Suntech because I just felt like Mike was the sharpest out of them all. He fully understood my situation and grasped the entire NVR ecosystem more fluently than all the others, and he has an excellent memory too! On top of that, I feel that Mike truly cares about his clients- he's not in the business only to make money, but rather to make a truly positive impact in his clients' lives. The actual installation went smoothly and it feels so much better knowing that my whole house is now covered both inside and out at every angle with 24/7 continuous surveillance. Having that peace of mind is priceless and I'm so thankful to Mike and the Suntech team for it!

We had a very disappointing experience with this company…read more We paid $11,170 upfront for camera systems across two business park locations. Only one location was completed (Osgood Rd), with a total project cost of $10,668.58. The second location (Selden) was never started, despite this process beginning back in September 2025. Despite being paid in excess of the completed work, the contractor is now demanding an additional $5,348.58 and claiming we do not own the installed system unless we pay more. He has came in the middle of the night specifically at 11:48pm and removed the installed equipment since we disputed his extortion and would not comply. At no point was there a written agreement stating that deposits were non-refundable, tied to specific projects, or forfeited if work was not performed. From our perspective: One project was completed One project was never started Funds already paid exceed the value of completed work Instead of resolving this professionally, the situation has escalated into demands for additional payment and threats. Based on our experience, I would strongly recommend that anyone considering this company run!!! Charlie is a con man.
