1. Indiana Alarm
Website: https://in-alarm.com/
Address: 8770 Guion Rd, Suite K

Schedule: Monday – Friday: 8:00 AM – 5:00 PM
Securing a home should not mean signing away your flexibility, which is why Indiana Alarm made it to our list. They operate on month-to-month agreements that let you fully own your custom-designed equipment from day one.
Instead of forcing you to buy a brand-new setup, they can seamlessly reactivate your pre-existing hardware and connect it to their Underwriters Laboratories (UL) Certified 5-Diamond Central Station monitoring.
I recently spoke with a homeowner who appreciated how this local team skipped the high-pressure sales tactics in favor of a free, customized design evaluation.
While their transparent pricing structure is refreshing, the highly advertised $18 monthly base rate strictly requires an active traditional landline. Upgrading to a modern cellular connection will noticeably increase your monthly bill.
Plus, the initial hardware and installation costs run higher than those of massive national chains, making the upfront investment a bit steep for tighter budgets.
The system and user interface is amazing!
Dustin showed up promptly today for my home security install. He communicated thoroughly, not too much, and did a great job on the install. The outside lights are blunted perfectly, you can tell her knows what he’s doing. When someone has worked there 7 years, and loves their job, that’s a company I want to work this. Hats off! The system and user interface is amazing! He always helped setup all the camera perimeters and showed me the app.

Very thorough and knowledgeable
Justin Fields is a very thorough and knowledgeable technician. We changed routers in our home and tried very hard to connect our video cameras to the new internet router without success. Justin was able to do this and help us with another issue and give us an estimate for some additional work. He’s extremely friendly and easy to understand.

2. Nelson Alarm
Website: https://nelsonalarm.com/
Address: 2602 E 55th St
Contact: 317-255-2125 | [email protected]
Schedule: Monday – Friday: 8:00 AM – 5:00 PM
Keeping your security management completely local eliminates the frustration of distant call centers, and Nelson Alarm handles everything directly out of Indianapolis.
They don’t rely on generic kits for commercial spaces. Instead, they design specific business packages and maintain a massive inventory of in-stock parts to ensure immediate repairs.
Property managers can use smart integrations to assign temporary access codes. Advanced systems also provide environmental alerts for carbon monoxide and extreme temperature changes.
The main drawback of this hands-on approach is that it requires professional installation. This rules out any budget-friendly, self-setup options.
My tech Mitch was soooooo helpful
My tech Mitch was soooooo helpful and very knowledgeable about his work!!!! I would recommend Nelson to anyone looking for reliable service!

Nelson has been incredibly amazing
Nelson has been incredibly amazing. We had a few kinks in the beginning, as is such with any technology. They worked everything out exactly as it needed to be and are always available when we need them. The technicians are knowledgeable, and they seem to all be a great team.

3. Guardian Protection
Website: https://guardianprotection.com/service-areas/smart-home-security-in-indianapolis-in/
Address: 4013 Vincennes Road
Contact: 800-776-8328
Schedule: Available 24/7
Building a robust defense for your property requires proven expertise. Guardian Protection brings over 75 years of experience backed by an award-winning monitoring facility.
I really love that they offer a comprehensive, free professional installation performed by their in-house technicians. It ensures your system integrates flawlessly with modern smart home automation.
If you are currently working with top construction companies on a new commercial build or residential renovation, their team can come out for a no-cost, on-site estimate to map the layout.
This level of white-glove service guarantees that every door lock and thermostat communicates securely.
That said, the company outright refuses to sell self-installed configurations. This means you cannot order the hardware to set up yourself.
You also need to watch out for their billing guidelines. Requiring technical support that results in an on-site or virtual service appointment often incurs additional charges.
I highly recommend Omar for any installations!
Omar, our security tech, was incredibly knowledgeable, experienced and professional. There were a couple hiccups with our devices going into the installation, but Omar knew what to do and how to fix it. I really appreciated his thoroughness in explaining all the functionalities of the system. I highly recommend Omar for any installations!

4. OnGuard Security Solutions
Website: https://www.weareonguard.com/
Address: 5355 E 38th St
Contact: 317-572-5777
Schedule:
- Monday – Friday 8:00 AM – 5:00 PM
- Available on call 24/7
Fusing your fire and burglar alarms into a single cohesive platform drastically reduces maintenance headaches, and OnGuard Security Solutions specializes in this exact type of integrated defense.
They utilize advanced Long-Term Evolution (LTE) and 5G cellular transmitters, ensuring your system stays online during power outages, and back their custom fixed-bid projects with a strict $100 quality guarantee from the owner.
When I visited a recently upgraded retail space, I saw firsthand how their cloud-based access control provided the staff with seamless video tracking and intuitive user management without bulky hardware.
Unfortunately, their sales department operates strictly by appointment only. This limits immediate purchasing options if you are in a rush.
Plus, they mandate professional installation, meaning do-it-yourself (DIY) enthusiasts are entirely out of luck.
Extremely professional and efficient
Tony was sent out to our commercial properties for Sherfick Companies and was extremely professional and efficient. Had our problem resolved within a couple hours and allowed me to ask questions while working for further understanding. Would recommend to anyone in the future!!

The technician was friendly and knowledgeable
Had an issue where I couldn’t view any of my cameras whenever I was away from home. So we scheduled a service visit. Tony came out and had us back up and running in no time. The technician was friendly and knowledgeable, fantastic customer service. Thanks Onguard and Tony!

5. Hoosier Security
Website: https://hoosiersecurity.com/
Address: 7828 E 88th St
Contact: 317-644-0570 | [email protected]
Schedule: Monday – Friday: 9:00 AM – 5:00 PM
Industrial facilities require heavy-duty oversight, and Hoosier Security delivers by utilizing advanced 3D software to virtually map out your entire property before pulling a single wire.
Because they strictly avoid long-term monitoring agreements, enterprise clients fully own their customized equipment from the start. They also benefit from a unique three-year commercial warranty.
I also learned that the team resolves technical issues within 1 business day to minimize disruption.
Even better, they can choose the best hardware from different brands to fit your needs since they’re an independent contractor.
While their high-end setups are incredibly impressive, they focus almost exclusively on commercial and industrial operations. This leaves standard residential homeowners to look elsewhere.
Business owners must also adhere to strict billing timelines, as the company reserves the right to charge a steep 12 percent annual penalty on late payments.
They did an awesome job
We were up against a tight deadline, and Dhasha and Joe worked their magic to get everything scheduled quickly. Brian M then did an awesome job with the install. Even though we had a difficult run getting the system connected, he stayed on it and got everything resolved. He was courteous, professional, and great to work with. Hoosier Security is lucky to have such an awesome team, and I highly recommend Hoosier Security.

The Hoosier Team has been a great help
The Hoosier Team has been a great help with us completing our camera project! A huge recognition goes out to the techs that came down to get this done for us; David Z, David B, and Nathan! We’d love to have these guys assist us again in the future if possible. Many thanks again!
