Fence jump detection
The moment someone goes over a wall or gate, the camera flags it and an agent is on the live feed.
The LandMark Group provides security and intelligence for Chicago's property managers, corporate entities, private residences and executives. Every plan we build begins with the people it protects.
The same intelligence-led approach is tailored to each client's priorities, risks, and environment.
Protect the property, its tenants and its reputation.
Secure your staff and your proprietary information.
Protect your family and home. Identify and stop a threat before it's too late.
Discreet protection wherever life and work take you.
Whether it's a family home, a Class-A office property or a corporate headquarters, every engagement follows the same disciplined process.
We assess the people, the property and the routines around them to find where you are exposed.
Each vulnerability is weighed by likelihood and impact, so you know which risks matter most.
We assign the appropriate level of protection, from officers and monitoring to training and policy, then reassess.
Whether you manage the property or lease space in it, the lobby is the first impression and the first line of defense. Our officers are hired and trained to handle both.
Sworn, off-duty police officers offer a discreet but commanding presence in your lobby.
Staffed by off-duty police officers, with regular check-ins at your property, response when requested and focused attention wherever a problem keeps recurring.
Officers respond, document and keep property management informed, with clear reports you can act on.
For private homes, LMG agents watch your cameras in real time and stop an intruder before anyone reaches your door. Watch how a response unfolds.

The moment someone goes over a wall or gate, the camera flags it and an agent is on the live feed.

Motion in the yard after your set hours is treated as a priority event, not a notification you'll find in the morning.

Our agent speaks directly to the intruder through the camera's speaker, and escalates to police when the situation calls for it.
For executives, their families and visiting principals, we combine close protection with the intelligence work that comes before it: knowing who is around you, what is being said about you, and where the risk actually is.

The LandMark Group was founded by Steve Peterson in 2011 and is run today by Matt Peterson. Our team is a small, hand-selected group of experienced professionals, and that experience shapes everything we do: assess the threat first, then build protection that acts on it.
Every client, from a downtown office tower to a family home, gets a plan designed around their property and the people in it, and a team that knows both.
Whether it's a property, your company, your home or your family, we start by walking it with you, identifying its vulnerabilities and showing you where a threat would come from. Private and confidential.
Serving office properties, residences and executives across the Chicago area.
