“Free” alarm systems are the industry’s dirtiest trick.

Companies that give “FREE” systems are simply hiding the equipment cost in a high monthly rate of $50-$90/mo under contract. They’ll claim it’s a way to finance the equipment for you to reduce your upfront cost. First of all, that proves it wasn’t really “FREE” in the first place, but lets talk about that. If they are financing it for you, shouldn’t your monthly rate go back down after the equipment is paid off? It doesn’t. You will be stuck overpaying for 3-5 years, and your contract will auto renew. We’ve been around since ’78, and we know what parts really cost. That equipment is actually paid off within the first year! With us, you may pay a little more upfront, but you’ll pay a lot less long term. You’ll know exactly what you’re pay for, no secrets.


We offer transparent pricing.

With us, you know what you’re REALLY paying for. The equipment price is separate from the monthly monitoring rate. Once the equipment is paid for (whether you pay upfront for a discount, or finance it), all you have left is our low monthly rate. No contract. If you do the math over a typical 36 month term like most companies require, you’ll find we’re a MUCH better deal.

Small Biz FAQs

We are primarily a residential company, but we can handle light commercial applications up to 4,000 sq ft. If you’re not sure, just give us a call we’ll be happy to see what we can do. If you have a large structure, we highly recommend DSS Security.

Yes- High risk locations like jewelry stores, 24HR locations, coin laundry, and liquor stores are a few examples of places we can’t monitor for insurance and liability reasons (we are primarily a residential company). For locations we can’t monitor we highly recommend DSS Security or Kelltech Systems.

Because we are primarily a residential company, we are not set up to for garage or warehouse applications. We only handle light commercial spaces like offices and small retail spaces. For warehouses, garages, or larger spaces, we recommend DSS Security or Kelltech Systems.

Yes! The touchscreen IQ2 automation system starts at $39.95/mo for commercial applications. That includes the full-featured alarm.com app, with stay/away arming, and notifications. The IQ2 is compatible with cameras, lights, locks, thermostats, and more.

Our technician will collect with check or credit card on-site for any equipment we’ve sold you, as well as the first billing cycle of monitoring to get your service started. We have two billing cycle options to choose from: Monthly Auto-Draft, or you can pay annually and receive 1 free month (pay for 11 and get the 12th free).

There is no contract! Since 1978, we’ve been able to keep our customers with great service. Should you need to stop service though, all we require is a standard 30 day written notice.

A dispatcher immediately calls you on any number you would like us to call. If we don’t receive an answer, the police or fire department are dispatched to your home. If we do receive an answer we verify your password, and at that point you can decide if you want us to dispatch or not. We never charge for false alarms.

Yes! We have a true online quote system here. Or give us a call during business hours, and our sales staff will be glad to help you out. Dial 888-888-1695, press option #1.

Your city probably requires a monitoring permit (not an installation permit). Contact your local police department, or search their website for more info. Most cities allow you to at least download the registration form off their website. Once you’re registered, be sure to call and give us your permit number.

We do not. Commercial fire monitoring is typically handled by a separate fire system that the building’s management controls. For that reason, we do not carry commercial fire licensing.

We do not. Because we are set up for light commercial applications, and most light applications don’t require them, we aren’t set up for open/closing reports. A better option would be to install a wireless camera from ARLO. That way you also get a video clip with your timestamp, as well as increased security in general. We also recommend speaking with DSS Security and Kelltech Systems.
