Frequently Asked Questions

Common questions about private security services in Northbrook, Illinois:

QWhat are the licensing requirements for private security companies operating in Northbrook, Illinois?

In Northbrook, Illinois, private security companies and their employees must be licensed through the Illinois Department of Financial and Professional Regulation (IDFPR). Security guards must complete 20 hours of training, pass a background check, and hold a valid Permanent Employee Registration Card (PERC). Companies themselves must also be licensed. Northbrook may have additional local ordinances, so it's important to verify with the Northbrook Village Clerk's office that your chosen provider meets all municipal requirements.

QWhat types of private security services are most commonly used by Northbrook residents and businesses?

In Northbrook, common private security services include residential security patrols for the village's many single-family homes and upscale neighborhoods, access control and concierge services for condominium and apartment complexes, and event security for gatherings at local venues like the Northbrook Sports Center or the Northbrook Public Library. Businesses, particularly those in the Northbrook Court area and the industrial parks, frequently use alarm response, video surveillance monitoring, and on-site guards to deter theft and vandalism.

QHow much does it typically cost to hire private security for a home in Northbrook?

The cost for private security in Northbrook varies based on the service. For a single, unarmed security guard for a residential event, you might pay $25-$40 per hour. For ongoing, dedicated patrol services for a home in a neighborhood like Techny or Stonegate, costs are often structured as a monthly fee, typically ranging from $200 to $600 or more, depending on the frequency of patrols and level of service. It's best to get quotes from several licensed Northbrook-area providers, as prices can be influenced by local insurance and operational costs.

QWhat should I look for when hiring a private security firm for my Northbrook business?

When hiring a security firm for your Northbrook business, first verify their Illinois state license and PERC cards for all guards. Look for a company with specific experience serving businesses in the Northbrook area, as they will be familiar with local crime trends and have established relationships with the Northbrook Police Department. Check for proper insurance, including general liability and workers' compensation. It's also wise to ask for references from other local businesses, perhaps in your same plaza or industrial park, to gauge their reliability and professionalism.

QCan private security guards in Northbrook make arrests or detain individuals?

In Northbrook, private security guards have the same arrest powers as any private citizen under Illinois law, which is often referred to as a 'citizen's arrest.' This means they can detain someone if they have witnessed a felony or have reasonable grounds to believe a person has committed a felony. For misdemeanors, they can typically only make an arrest if the offense was committed against a person or property they are contracted to protect. However, their primary role is to observe, report, and deter crime, and they must immediately contact the Northbrook Police Department to handle any formal arrest and custody situation.
