Congrats on getting your company started. Let me share my opinion as someone who was recently in the market for security systems. Hopefully some of this can help.
Who is your REAL focus thats makes you unique from other companies in this space? On your homepage title its "Why pay an installer when you can do it yourself?"
So you're after the DIY market. IMO, pretty cramped with the residential crowd and there are some great choices out there already. Pretty much the crowd, like myself, who didn't want the old school companies like ADT who jack you on the monitoring and shit contracts and were looking for a different soultion.
You got people with normal sized homes, condos, renters, etc.. They want DIY but have limited to no skills in this area and don't want to pay ADT prices. Do you know about SimpliSafe? I beileve this company will utterly destroy all competition in this space in the future. Hit up their site: simplisafe.com
From a marketers perspective they have it ALL covered. Right on their front page you got everything you can think of: benefits, features, famous testimonials, videos, plays on emotion, they just make everything seem easy for the prospective buyer. And it is. That whole web 2.0 feel to the entire site, I can tell you that design like that can win over more customers then the product itself sometimes. On top of it their product is super simple for the average DIY'er and the prices for the equipment and most importantly the central station monitoring, really can't be beat. I have referred numerous people to them and they all rave about it, especially the ones coming from the big national companies. They really got a lock on this growing market - DIY who want plug and play, no real skills.
For the DIY'er with a decent skill set and knowledge of the space, you got "HomeSecurityStore". I've used them when I purchased my new home, I know a decent amount but nothing on par with a home security pro. I put together a good system that was priced right and their monitoring is priced very competitively. Site has a nice design, good feel to it with a ton of details and information. Articles, videos, etc.. Has established trust in this niche. I know pro installers who use this site for thier customer installs. They seem to have a good stronghold in this market - DIY who already have skills and like to tinker with shit.
On to business/commercial. I haven't really looked into this niche of the market, is it untapped? DIY alarms for business owners? Not sure, but I know when I was doing risk management for an insurance company, I met with plenty of business owners - meaning commercial storefronts to multi-unit residential, who wanted systems but didn't want to pay pros or the national account prices. Maybe something like a SimpliSafe for commercial?
Also take a look at this thread over at fatwallet:
2012 Alarm Monitoring Thread: Get Rid of ADT/others - smarthome.com, alarmrelay.com - $8.95/mo w/ one time $35 setup fee
Pretty much residential but they dissect everything regarding DIY alarms. Maybe you can gain some tips from the consumer prospective.
