The Good

Over 50 Years Experience
More Transparent in Pricing Than Its Competitors
No Landline Requirement
Z-Wave Compatibility

Security Instruments Corp. offers security systems and monitoring for residential and commercial customers. The company has been providing services since 1960, and is one of the more experienced in the industry. The company shares its pricing, which is more than most of its competitors do. Security Instruments Corp. offers its new customers a package that will cover most needs, with a control panel, several door/window sensors, and an interior siren. The system can easily be expanded, although the company does not disclose the pricing to do so. Customers are able to have a system even if they do not have a home landline, as the company has equipment that works on a cellular network. Customers can have equipment installed that can employ a high-speed internet connection to communicate with the monitoring center. While many companies blur the line between home security and home automation, Security Instrument Corp. offers its customers a true security solution. Customers can add home automation components into their system, which is compatible with most Z-Wave devices.

The Bad

Small Geographic Service Area
Lack of Transparency on Contracts
Some Reports of High-Pressure Sales Representatives

Security Instruments Corp. has a relatively small service area, so customers may not be able to continue their service if they move. The company, while more transparent than many of its competitors, still lacks some transparency with its contract, cancellation policies, and add on prices. Additional transparency would be beneficial to potential customers as they compare companies. Having an option for a starter package is something that many companies do not do. Security Instruments Corp's package should work for many homes, but is not custom-designed or quoted as are systems sold by other companies. Some customers complain that receiving answers from the customer service department is arduous. Others report that the company's sales representatives engage in high pressure sales techniques and even some scare tactics to close sales, which methods are generally unappealing to many.

The Bottom Line

There are many positive aspects of Security Instruments Corp. for customers in its service area. The company's experience is significant in an industry that is filled with companies that have only been in business a few years. Customers can add home automation to their system with the widely used Z-Wave communication protocol. Of concern, as it is with most of the companies in the industry, is that the company is not transparent with the full terms of its monitoring service contract. While similar to other companies in the industry, improved transparency would benefit customers greatly.
