1. Colorado Security Company

Contact: (303) 756-1000
Hours: Weekdays, 9:00 AM – 6:00 PM
Finding a security setup that actually fits your floor plan can be tricky. Luckily, Colorado Security Company delivers customized solutions.
Instead of selling you a generic, pre-packaged box of sensors, they build a customized plan tailored to the exact layout of your home or office.
I also love that they use their own in-house rather than random subcontractors. This means that the person installing your gear actually knows how it works and is accountable for the quality of the job.
They also run their own local monitoring center right here in the area. This is a huge plus, as it guarantees that emergency services are dispatched rapidly when needed.
While their service quality is excellent, finding a convenient time for setup can be a challenge. They have limited availability for weekend or after-hours installation appointments, so you’ll likely need to adjust your weekday schedule.
Customer Reviews:
20/10 experience with everyone at Colorado Security Company. Brandon was very down to earth and honest about what we needed after assessing our home. Todd and Sara were great communicating every step of the way getting our appointment set up. Rustin was awesome to work with during the install and helpful with getting us set up. Couldn’t recommend them more over the big competitors.

The team I worked with – Brandon, Todd and Cody- were fabulous. Professional, responsive and helpful. Based on the customer service alone I would recommend Colorado Security Company. The product and accompanying tech look sleek and user friendly, even for a non tech guru like myself.

2. Security Central Inc.
Website: https://www.securitycentralinc.com/
Address: 67 Inverness Dr E unit b, Englewood
Contact: (303) 713-1000
Hours: Mon – Sat, 7:30 AM – 5:30 PM; Sun, Closed (Monitoring is 24/7)
Security Central Inc. is a family-operated firm that has been serving the Denver metro area since 1969.
They provide a high level of defense through their own monitoring facility, which is a top-tier, UL-listed station located right here in Colorado.
By utilizing a private station, they bypass third-party call centers entirely, giving clients direct access to local support.
I spoke with a local property manager who has recently upgraded their buildings. They specifically praised how this company handles environmental hazard detection alongside standard break-in protection.
Their flood and freeze sensors are a lifesaver during unpredictable Colorado winters, too. Their cellular backup keeps things running even during power outages.
One downside to consider is that they’re strict about quality; they require professional installation for every system. You can’t go the DIY route here to save on costs, so the initial investment is slightly higher than standard kits.
Customer Reviews:
An amazing team- 2 men and 2
women- installed our system today. They worked all day, were attentive to requests and questions and found solutions for all the difficulties posed by a 1932 era brick home. We were really impressed with their ingenuity and knowledge and last, but not least, they also cleaned up before they left. We initially felt the estimate was high, but the service would probably be good at that price. It was worth it. So far on day one we are happy !

It’s clear they truly care about their customers and the level of service they deliver. I’m grateful for their reliability and highly recommend Security Central.

3. Denver Secure LLC

Hours: Sun – Thurs, 8 AM to 8 PM; Fri, 8 AM to 4 PM; Sat, Closed
A strong alarm is great, but physical barriers are just as important to completely protect your space.
I’ve found that Denver Secure LLC is one of the few teams that bridges the gap between old-school locksmithing and modern electronic security. They offer a complete physical and electronic barrier for your property.
Furthermore, technicians are experts in both heavy-duty commercial access doors and standard residential setups, which gives them a very well-rounded defense strategy.
I love that they provide 24-hour emergency response for any immediate security issues in the metro area. They also use a transparent, flat-rate pricing structure, so you won’t be surprised by the bill.
However, because they’re a smaller boutique team, you might run into a minor drawback. Their size can lead to longer wait times for non-emergency upgrades, which could delay your routine home enhancements.
Customer Reviews:
After trying to DIY my own solution, Denver Secure came to the rescue and sorted out what was needed, where things could be improved, and installed and configured everything exactly as it should be. Trevor was fantastic, knowing all the ins and outs of the installation and helped troubleshoot a way to tie it into our home automation system. Really happy with the end product, I’d certainly recommend

4. SafeStreets
Website: https://www.safestreets.com/home-security-systems/colorado/
Areas Served: Denver
Contact: (844) 936-0563
Hours: Mon – Fri, 8:00 AM – 8:00 PM
SafeStreets is an authorized provider that pairs a massive national equipment network with local installation pros to give you the best of both worlds.
They install highly tested gear known for long-term stability. And for easy remote control, they connect intrusion panels directly to smart home devices, which is convenient.
A friend of mine who recently moved into a large suburban home used them and told me how seamlessly they managed to link the new locks and lights to a single smartphone app.
I also love that the company uses a national network of monitoring centers. With this, if one center goes down during a regional disaster, another one picks up the slack instantly for continuous coverage.
They’re also great if you are in a rush, since they accommodate same-day installation requests.
The main catch involves their long-term service agreements. You’ll usually need to commit to a multi-year monitoring contract, which might not suit short-term renters.
Customer Reviews:
Great experience with Joe from ADT! The installer was on time, courteous, and very thorough. He made sure everything was working perfectly and answered all of my questions. I really appreciate the care and professionalism. He made sure we were covered!

5. Security Surveillance System
Website: https://www.ssscamera.com/
Address: 10630 E Bethany Dr a, Aurora

Hours: Mon – Fri, 8:00 AM – 5:00 PM; Sat – Sun, Closed
Sometimes, seeing exactly what is happening on your property is the most critical part of staying safe, and Security Surveillance System is the go-to for high-definition video networks.
For starters, they focus heavily on advanced camera placement to back up your traditional fences and alarms.
Since they specialize in video analytics, their cameras are smart enough to differentiate a stray cat from a person. Plus, their high-resolution hardware provides incredibly clear footage.
As for their expertise on multi-building commercial sites, I like their scalable systems which enables clients to start small and easily add more cameras as the business grows. They even provide detailed training after the install.
One thing to consider is that because they are so focused on video, their basic alarm options are a bit limited.
Their non-video packages aren’t quite as robust as what you’d find with a specialist, so extra equipment if you only want standard door and window sensors.
Customer Reviews:
Michael did a wonderful job adjusting our cameras. He was professional, knowledgeable, and made sure everything was set up perfectly. What really stood out was that he asked us to review his work to ensure we were completely satisfied, which shows how much he cares about doing things right. Overall, we’re very happy with the service and would definitely recommend him.

Security Surveillance System should be your go-to security specialists if you’re in their area. Their techs are knowledgeable, extremely good at what they do, and friendly! They helped me find the right equipment for my needs, they arrived promptly at the appointed time and even brought spares of equipment in case I’d forgotten to order it or what I got was DOA (I very much appreciate people who prepare appropriately!), and the install was done and dusted in under an hour. Absolute bloody legends, if you need a security solution call SSS now!
