Exceptional service throughout the camera installation process. HM Security provided a great price, and Tony, the technician, was professional, knowledgeable, and always available to answer any questions I had. The installation was completed efficiently, and the overall experience was excellent. read more

If you're looking for a security company that cares only about pumping up their installation numbers and absolutely not about the customer, congratulations -- you've found it with ADT. They extended my contract an extra year without even telling me, just casually expecting me to sign off on it. When I refused (because who wouldn't?), they ended up not even finishing the install -- leaving me with ugly holes in my wall and zero accountability. Apparently, your home is just collateral damage in their rush to hit their quotas. Customer service? Forget it. Transparency? Nonexistent. Special thanks to Rey Zendejas for the stellar experience (note the sarcasm). read more

HM Security - iPhone - Security Systems Near Me - Downey, California

I called this alarm company to ask a few basic questions about their services, specifically about how they differ from ADT directly since they claim to be an "authorized retailer." Instead of a professional explanation, I was met with attitude and defensiveness. As a potential customer trying to do my due diligence, I found it extremely off-putting that they couldn't handle a simple question about their own reputation without getting upset. If this is how they treat someone before a sale, I can only imagine how they'd treat customers after installation. Totally unprofessional and a red flag. I'll be taking my business elsewhere. read more

What a great company to deal with, could not have asked for anything better. We were unfortunately broken in to living in El Serreno for over 10 years. We never though it could happen to us but it did. We were in need of a security system and a reputable company to help us feel safe again and we found them. We got our business protected with them as well. Thank you Jose and Rey from HM. You guys are the best! read more

I appreciate their professionalism, clear communication and efficient installation process. They worked with our budget and provided transparent pricing. The equipment and installation was included in a flat upfront Fee that required a 24month contract. I recommend them to anyone seeking a credible surveillance and alarm company. read more

My experience with HM security and Rey in specific is amazing. He went above and beyond to meet my requirements in limited budget, beat other quotes like Vivint and eventually earned my business.

I can't say enough great things about this security company! Their professionalism, reliability, and dedication to safety are truly unmatched. A huge thank you to Reynaldo for going above and beyond--his attentiveness, professionalism, and commitment to excellent service did not go unnoticed. He made us feel secure and well taken care of at all times. If you're looking for top-notch security services, look no further. Highly recommend! read more

OMG! This company is awesome. I was instructed by my employer to get 5 estimates for security cameras for a small commercial property. I had the pleasure of communicating via phone and text with Rey. He was very prompt & patient at responding and providing answers to my MANY questions. He never made me feel like I was bothering him. Rey clearly explained how each plan works and what the differences are so that I can make the right decision. After getting several estimates it was clear that HM Security was definitely A CUT ABOVE ! They were not the "cheapest" I found, but what they offered outweighed the competition BY FAR! The installer Alex came out and in 2 days had installed 13 cameras for us to cover the entire property. He patiently took the time to install the software onto our phones and show us how the system worked. The HD quality is phenomenal! They surpassed all the competition in customer service and experience. I have referred them to several friends and plan to use them for my home security cameras as well! Excellent product with outstanding customer support. No other business like this for security cameras. Would highly recommend them for your business and home use! read more

In 2018/2019 We had HM Security install our ADT, a month later we had many malfunctions with the sensors, no one would return our call for service. I filed a complaint with the BBB, no reply. In 2020, we moved and went with Blue system with ADT. Rey Zendejas called and indicated he would have a technician come and hook up our new service if I removed the negative comment from BBB because he was trying to rebuild. No problem, I did. However, he failed to deliver. I am posting today in 2021, because not only would I not recommend HM Security, I would not recommend ADT service. read more

Outstanding service!!!!! Will definitely recommend to my friends and family!!! Very helpful and timely and professional service!!!! read more

This review is long over due. My Friend referred me to HM Security when I told her I was looking for a security system back in June. I spoke with Rey, told him I was looking for cameras as well as an alarm system, and he gave me multiple package options. Once we spoke details, he immediately set me up with one of his specialists and they were at my house within a few days. Rey's point of contact, Ana, kept me up to date with the process, what to expect, and how long the installation would take. Any questions I needed answered, Ana was available to answer and still does to this day. They were extremely professional and their pricing is great; they're even there to help you out AFTER your system has been installed. I've already referred them to my Family and will continue to do so to anyone who needs an alarm system. Thanks HM Security! read more

Julian did a great job setting up my home security system fast, flexible and friendly.

This review is for Rey Zendejas who came to our home for an upgrade of our existing home security system from Brinks. He came to our home as promised and was very responsive to our calls and texts after we agreed on a plan. His team took care of the cancellation of our old Brinks account. We have had the system now for a couple of weeks and we are very pleased. Also, Shout out to our Tech, Hector Vela, who put up with me and our loud family as he worked on the wireless connection of the cameras at our home. He did a great, clean job despite all the distractions going on around our house with our children, our dogs, my wife and me. I highly recommend Rey and HM Security. Well done guys. read more

I just had my alarm/camera system installed. From day one, Hector our Technician went out of his way to help me select the right system for the right price. He works fast, is organized and cleans up after himself. Hector made sure my kids and I knew how to use the system before he left. I will definitely refer him to all my friends and family. read more

They have been reasonable with their prices. The few times that I have forgotten to turn off alarm before coming in the house , they have called right away to make sure everything is okay. read more

HM security is awesome!! We had quite a scare when our home was broken into last week so we knew we had to take action in protecting it. One of my close friends referred me over to this business and specifically Rey. Rey was so helpful and friendly from start to finish. He helped us pick out the best package based off of our needs. We ended up choosing an alarm system and cameras and we couldn't be happier. Everything works great and the customer service is exceptional. Thank you HM security and thank you Rey for all your help! read more

They did it again!!! Ray and his team are so amazing. I couldn't be any happier with the service they provided this time around and two years ago on our previous home. Ana worked on her own for over 4 hours due to the massive amount of windows we have in our new home. She was knowledgeable and gave us the run down with the new app this system and new touch screen panel provides. If anyone of you are looking for an alarm system I recommend you give Ray a call and I guarantee you won't regret it! Thank you all so much for all you do and for always keeping my children and I safe! read more

HM Security - I'm in love with our new touch screen panel! It's so user friendly, she's a beauty. - Security Systems Near Me - Downey, California

I'm so glad I called Rey to get my house Alarm. I couldn't be happier with the service he provided. He sent his technician hector to install my alarm and it was a job well done. Came on time and was very professional. He explained in good detail what he was going to do and how to use the alarm system after he was done. I highly recommend Rey and his team they did an awesome job. One of my favorite features is that I can now monitor my home when we are away and know we are protected as well. Yay!!! read more

I've had my business for 9 years now. We've never had any incident happen or any reason to cause anyone a reason to do so. Last week someone came in to my business at held my daughter at gunpoint. Took her to the restroom, tied her moth shut and robbed us. We have been terrified and in fear. We called HM security and they sent Rey to give us an estimate. We were expecting to pay a large amount of money and we were shocked to learn he was able to do everything we needed at no cost. We still feel shaken up but a lot better knowing we have a panic button and cameras to record us while conducting business. Don't think you're safe because nothing has happened. Take the measures and steps to protecting yourself. I will be recommending Rey and HM security to all my family and friends. read more

Our firm hired HM Security to install cameras and alarm systems in 3 locations, including my home.

Thank you Ray for an amazing service. We've worked with him for a while now and he's the BEST. We got a couple location that he helped us set up and I have no complaints. Will definitely keep working with him in the future! Highly recommend!!! read more

My elderly father in law had been living by himself for a few years until he had a bad fall which caused him to be hospitalized for a few months. Aside from worrying about his recovery, I was also stressed that someone would invade his home while he was gone. I searched for home security and i'm very happy that I came across HM security. Rey Z. was the person that helped me through this worrisome situation, he quickly put me at ease and made me feel confident in his abilities and expertise that my Father in law's house would be safe and secure. I really appreciated that Rey displayed professionalism from the very beginning to the end. Not only that, but he went above and beyond to get me the proper security I needed for the complexities of the home which I thought would be impossible to do. It's been about two months with the home security and I am loving it! The home security can be accessed through an app and it has been so convenient. Rey also installed cameras and I am very impressed to see the clear picture(not pixilated at all).I'm very grateful for the amazing job Rey was able to do for not only me but my family. DON'T HESITATE, ask for Rey! He is very passionate about his job and takes it very seriously. -Susie read more

My abuela is finally feeling secure.. Thanks to HM Security and their amazing service!

José was gReat! Really nice and patient, I arrived late and he was very nice about it, he did a great job no messes everything clean for my business. Great work and people read more

Horrible service and communication from Rey Zendejas... His tech installed cameras for me 2 years ago and i wanted to upgrade, so after so many calls and texting i finally was able to get an appointment so they can come out and install the new ones.. I took a day off to wait for his tech to come out and do the job... That day, it rained alittle...Rey did not have the courtesy to call or text me and let me know that his tech was not coming.. Instead he calls me the next day saying he was sorry his tech did not come out to install the cameras... I hired someone else.. I would not recommend Rey Zendejas read more

Jennifer was awesome didn't try to sell me something I didn't want or need she was very professional and I loved that she was straight to the point. Awesome we were done like in 10 minutes I'd most definitely recommend her to friends and family Thank you read more
