Security Systems in Lexington, MA

An addition, an accessory apartment or a change of tenants can leave a good alarm protecting yesterday’s layout. Cunningham Security installs and services intrusion alarms, cameras, access control and professional monitoring for Lexington homes and businesses, with a plan for the entrances and people using the property today.

Tell us whether you are starting fresh, renovating or taking over an existing system. We can assess the equipment and the building before recommending what to keep and what to change.

Plan around the doors you actually use

A front-door camera alone may miss the entrance your family uses most. Begin with a walk through the garage connection, side doors, basement access and any rooms added after the original house was built. The resulting plan should make arming the alarm straightforward when everyone leaves and allow suitable perimeter protection when people remain at home.

Older home or existing wired alarm

Check the condition of contacts, cable and accessible wiring before replacing them. If walls are plaster, masonry or otherwise difficult to open, compare retaining sound wiring with adding compatible wireless devices. Test radio communication in the actual locations; an attractive floor plan does not show every signal obstruction.

Addition, finished basement or new layout

A renovation can create a new entrance or a route through the house that the original alarm never covered. Review the whole perimeter and everyday movement instead of simply moving the old keypad. Discuss device positions while wiring routes remain accessible.

Accessory apartment or second household

Lexington’s accessory dwelling unit guidance describes apartments within a house or in a separate building, with separate entrance arrangements. Decide whether each household needs independent arming, app permissions and emergency contacts. Identify shared doors so one person’s arrival does not unsettle the other household’s security. For a detached unit, check its power, network and alarm communication options on site.

Our home security systems guide explains the wider choices. A Lexington site assessment turns those options into a specific equipment and installation scope.

Historic district work: settle visible equipment early

Lexington’s Historic Districts Commission reviews exterior work within the local historic districts. Before fixing an exterior camera, reader, enclosure or cable route, check whether the property and proposed work need review. An older house is not automatically within a local district, and the commission should resolve the applicability question.

For a project that does need review, identify proposed mounting positions and visible wiring before installation is booked. That allows us to discuss discreet placement and service access while preserving the view a camera needs. Concealing a camera behind a deep porch beam may improve its appearance but leave faces obscured; the design needs to satisfy both goals.

Register the alarm and teach everyone how to use it

Lexington Police directs residents, businesses and organizations with alarm or security systems to complete its alarm registration process. The town also publishes a false-alarm fee policy. Use the Lexington Police alarm registration and false-alarm page for the current form and terms.

Make registration part of activation or a change of ownership. Keep the people who can respond to an alarm current, and make sure household members, cleaners or employees know the correct entry route and disarming procedure. Repeated alarms deserve investigation: a loose contact, changed pet routine or confusing entry delay calls for a different correction than forgotten instructions.

Business security for changing buildings and tenants

Lexington’s commercial property needs extend beyond a storefront alarm. The town’s development project register includes multifamily approvals along Hartwell Avenue and Bedford Street. For owners adapting or managing a building, access rights and camera coverage should follow the actual occupancy and lease boundaries, rather than an old tenant’s layout.

For a small office, separate staff entry from visitors and deliveries. In a shared building, establish which doors and recordings the landlord controls and which belong to the tenant. A credential that opens the main entrance need not open every interior room. Our access control systems can help manage those permissions, subject to the building’s door hardware and life-safety requirements.

For security cameras, choose the result first: a recognizable person at an entrance, a useful view of a delivery, or an overview of a parking area. Those tasks call for different placement and coverage. Review lighting, trees, parked vehicles, recording retention and who may retrieve footage before selecting equipment.

Moving into a property with an existing system?

Send the panel make and model, photographs of the keypad and control cabinet, and a brief description of what works. Do not include alarm codes or account passwords in a general inquiry. An existing-system takeover review checks compatibility, ownership or account restrictions, communications and device condition. A keypad lighting up does not establish that signals reach a monitoring center.

Where suitable, professional alarm monitoring can receive signals when you cannot respond to your phone. Interactive app features depend on compatible equipment and the selected service. We will explain the proposed communication path, backup arrangements and recurring charges in the quote.

Ask for a scope that matches your next step

For a house, send the entrances to protect, pets, additions and existing equipment. Mention an accessory apartment or historic-district review at the outset. For a business, include opening hours, staff access needs and who controls shared areas. Cunningham’s Wakefield office is part of our Massachusetts service network.

Commercial life-safety work has its own approval and maintenance needs: see Lexington fire alarm installation, testing and monitoring. For another property nearby, explore our Bedford security guide or Burlington security guide.
