I recently contracted with Post/Peninsula Security. From sales to installation it was one of the best customer experiences. Knowledgeable, personable, efficient, helpful. I have confidence and respect and am grateful for the expertise provided. Highest recommendation. read more

We have used Peninsula Security for the past 8+ years and have found the company (specifically Maria and Jeff at the ofc.) to be responsive and efficient. I'd also like to acknowledge the stellar customer service provided by Matt Bishop. He is extremely knowledgeable, informative, punctual, and patient. I highly recommend this company for any security needs. Outstanding experience! read more

Now owned by Post Alarm company. Efficient. Timely install. Only negative was initial sales person left the company within days of signing up and no one bothered to tell me so I had to reach out to see what was going on. Communication could have been better. read more

Mark and his team are outstanding. Did the full wiring for my new home construction. I had originally gone overboard on what I had planned and he helped scale back the work to only things that would actually help and be beneficial for home security (ie, I dont need sensors on non-operable windows on the second floor, dont need motion sensors EVERYWHERE, etc etc). Really knows his stuff, works with a variety of systems, explained pros and cons of each until we determined what would be best for my situation. Enjoyed working with the team so much I recently convinced my parents to upgrade their system with Peninsula too read more

Excellent company, always a good experience to have the crew working in the house to set up the system. Very knowledgeable, very helpful and easy to work with. I have worked with several companies over the years. This one is a keeper. Highly, highly recommend these guys. read more

They are awesome! We looked into several alarm companies and are so thankful we went with Peninsula. Everyone is so helpful and kind, attentive when needs arise and our system is top notch. We can sleep peacefully at night thanks to these wonderful people. read more

My name is Magdy Ghabrial and I live in Palos Verdes since 1984. This is my third review for Peninsula Security. The installation of a very customized security system (that meets our unique requirements) by Peninsula Security, compelled me to acknowledge their their excellent work. Kudos to Mark for assembling his company competent team that I interacted with, from the technical skills of Matt to the friendly responsive office staff. I highly recommend this company. M.

We've been using Peninsula Security for about 5 years now. We found them after realizing out that our previous alarm from a big company was not only installed poorly, it was still registered to our old address (we found that out when it went off and the police never came). Peninsula came in, redid the install, fixed some sensors that were misplaced and upgraded a few components. Then registered it to their monitoring service. (We are using Alarm.com as well). We're 5 years in to using their system and monitoring and have only used them for routine maintenance calls or add-ons. Everything has stayed in perfect working order. They are reliable and very offer fair prices. I wouldn't hesitate to recommend them to anyone. read more

Highly recommended! They safeguarded out new office headquarters to the Max. In this day and age it's important as ever. The crew sent out was great to be around and did a really professional job. If there was any problems I'm sure they would be easy to deal with but there hasn't been none. Great company from start to finish! read more

Ours is an older system and we have since replace the battery ourselves without any problems. Recently I had a different problem and Janelle and Mark were very helpful and immediately responsive. The problem was on my end and they went above and beyond help figure out a solution, to include loaning me diagnostic equipment. I am upgrading this review because the battery thing was a one time issue and the current service was outstanding. Issue totally resolved. Thank you team @ Peninsula Security. read more

A nice gentleman just left our office about 10 minutes ago. We are so happy with Peninsula Security's customer service they deserve a cyber-high-five! They came out for a quick change in our system and I asked him about 2 other things. He had both maintenance items (like our showroom door beeping) fixed in 10 minutes. I wanted to give this guy a big hug for being so easy to work with. We have used Peninsula Security for over 10 years now. Every time we have a weird problem (2 months ago a power outage and the alarms were going nuts) and have called them, they have been polite, helpful and have resolved our issues in a timely manner. I HIGHLY recommend. Clark Adams Co. loves you folks! read more

Very caring and professional staff; patient with questions, thorough with information (and I've needed them to repeat instructions often!). Personable and I'm always happy to have them in my home when needed. They know what they are doing and they do it well, in a timely fashion, and with kindness and consideration. Also, they are reasonable for the service they provide. Can't recommend them highly enough. read more

Great service. I've used them for my last three homes so about 20 years. They are always honest. Never try to upsell. Always friendly. When they say they will be there, they are. They do a great job installing and making it look good. Just what you want in a security company. If I could give them 10 stars I would. read more

We are so incredibly happy with the work from Peninsula Security!!! Their quote for upgrades and installation was very reasonable. On the day of our new installations the crew arrived on time and were wonderfully professional and respectful! As with any security system that your learning it just takes one phone call to their local office to have questions answered by their very competent support team. And this is why it is so important to shop local and support community based businesses!!! Thank you Peninsula Security! read more

Mark and his team have been so helpful over the years and very quick to come out when something happens, which has only been with something not related to their system (damage to wire by a city truck). We can't wait to upgrade to a new system. But the old system has been very dependable and easy for our sitter to use! read more

Of all the home security options that have become available in recent years, we're glad to have had Peninsula Security for many years. I'm so pleased with the customer service they provide. I've become accustomed to impersonal service in general so when I've ever called with a question, I'm always pleasantly surprised to be treated like a friend. Janelle goes above and beyond to insure that our system is working properly when I've ever had issues (local cell coverage interruptions, etc). She is thoughtful, helpful, kind and knowledgeable. I've recently had the pleasure of meeting the owner Mark who educated me on the equipment (originally installed by another provider) and not only replaced a malfunctioning sensor, but upgraded our alarm.com equipment and removed and inspected motion detectors. There's no point in having all of this equipment if it isn't working properly so I'm not sure why I didn't call them sooner. I'm so appreciative and wish more local businesses could emulate this standard of caring and service for their community. Thank you! read more

I've known Mark for years and believe he is one of the most honest in the business. I read a review from someone else(Gary Putz or some such name) about a service call that his wife had requested and that they got charged for. Gotta tell you dude, nothing is free especially when you have called for service. Do you get free service when you call for repairs on your washing machine or air conditioning? Of course you don't (unless you expect everyone should work for free). And when it's a phone line that's not even related to the alarm then why on God's green earth should Mark take responsibility for that? Oh ya, so you think they should eat the battery charge since the tech. that came out didn't spell out in CAPITAL letters there might be a charge for that-well again Mark couldn't give you the kind of service that you expect if he gave things away!!!!!(guess when you go to the doctor and he charges you $15 for an extra Q-tip that he had to use on you without quoting you first you also whine) Regardless, my own experience with Peninsula Security has been great and I truly believe that their practices and business ethics are hard to match. read more

The service is prompt and courteous. Good company! We've had them for many years. We would definitely recommend them.
