In choosing a supplier, the security officer should focus on the reliability and reputation of the company and its ability to handle local installation and centralized monitoring. While the family's configuration and lifestyle are important determinants of the type and amount of security equipment needed, most systems should include contacts on doors and ground floor windows, fire protection, motion detection, a panic or duress alarm, and central station monitoring. Prices for home alarm systems can vary from an average of $1,300 to tight security systems exceeding $10,000. Contract central station monitoring costs typically range between $12 and $30 per month. While some companies consider the alarm system an employee benefit, this may result in it being taxable on the executive's income. Because such a system is more a necessity than a luxury, a sensible alternative is to absorb the costs of the system in the security budget. A good home security system reduces the changes of burglary robbery, home invasion, and even kidnapping and increases the chances of apprehension.
