Protection One Inc., a Lawrence-based company that provides monitored-security services, reported last month that it had recorded an increase in revenues for the fourth quarter, including a boost in its recurring monthly revenues.

Total revenues in the fourth quarter were $69.1 million, up 3.9 percent from $66.5 million during the same period a year earlier. Recurring monthly revenues totaled $20 million, up from $19.9 million a year earlier.

Such recurring revenues are up, year over year, for the first time in seven years, said Richard Ginsburg, Protection One’s president and chief executive officer.

The company’s retail additions climbed by 10.7 percent during the year, he said, while retail cancellations fell by 2 percent.

“We look forward to an exciting year,” said Ginsburg, whose company is following through with growth plans. “I believe we are well-positioned to consummate a merger with Integrated Alarm Services Group early in April and to tackle the related challenges of reducing costs, increasing RMR additions, lowering attrition and upgrading critical systems.”

For the fourth quarter, rising interest costs widened the company’s losses: $4.7 million, or 26 cents per share, compared with $2.2 million, or 13 cents per share, for the same period in 2005.

Protection One, with headquarters in the I-70 Business Center in North Lawrence, provides security monitoring services in the United States. Including its Network Multifamily subsidiary, which provides security services for apartments and other multifamily housing projects, Protection One provides monitoring and related security services to about 1 million residential and commercial customers.
