Security Systems in Exeter, NH
You should not have to damage a building’s character—or complicate everyday life—to improve its security.
Cunningham Security designs and supports alarms, security cameras and access control for Exeter homes and businesses. We can work from an existing wired alarm, add coverage in a finished building or plan the system while a renovation is underway. The goal is straightforward: protection that suits the property and is comfortable to use.
Exeter had an estimated 16,213 residents in July 2025. Census housing estimates for 2020–2024 put owner occupancy at 69.1%. Those figures describe the town rather than the smaller downtown census-designated place. See the Census profile for Exeter town. For owners and landlords alike, the right questions are who may enter, how the building is occupied and which changes the property can accommodate.
Check the exterior before choosing camera locations
If your building is in an Exeter historic district, the town’s Historic District Commission review guidance says proposed exterior changes need review before work. Ask whether your planned cameras, readers, visible cable or mounting changes require approval. A small device can still change an exterior feature.
Bring photographs and proposed locations to the discussion early. A camera may fit neatly near an existing entry light, but the view still has to show the person using the entrance. Concealing it too far under an eave can trade appearance for an unhelpful picture.
Inside, we can evaluate wireless contacts in rooms where new wiring would disturb plaster or trim. Sound existing cable may still be the best way to serve other openings. The choice can vary within the same house; it does not have to be all wired or all wireless.
Start with the place you want to protect
A house that has changed over time
Walk through the original rooms and each addition. Check basement access, the everyday entrance and any garage connection. Where an older alarm is still present, ask whether its zone descriptions match the current layout. A remodeled room should not remain a blind spot simply because the panel still appears normal.
A downtown shop or professional office
Separate customer access from storage and staff-only rooms. Think about the rear entrance used for deliveries and whether a cleaner arrives after everyone else has left. Individual credentials and clear opening schedules make those routines easier to manage.
A rental or shared building
Decide which entrances and equipment belong to the landlord and which belong to the occupant. Common-area camera access should have a clear purpose and a named administrator. Plan tenant changes so credentials can be removed without replacing every lock or sharing a permanent code indefinitely.
Exeter asks for people who can actually get inside
Section 820 of Exeter’s published alarm ordinance asks for site information and at least three contacts able to enter the building before a system becomes operational. It also sets escalating charges after three false alarms in a calendar year. Confirm the current filing process and applicability with Exeter Police at 603-772-1212.
For someone who travels, a contact list made entirely of people traveling with them will not solve an after-hours problem. Ask each contact whether they have current access and can reasonably respond. Review the list when a tenant, employee or property manager changes.
Good setup also prevents avoidable alarms. Users should understand their normal arrival and departure routine, while contractors and cleaners need access suited to their schedule. If one door repeatedly fails to close properly, have it investigated rather than repeatedly working around the problem.
Read local incident reports without turning them into a scare story
Exeter Police publishes weekly press logs. They are useful for following reported local incidents, but a selection of log entries does not establish an annual crime rate.
For your property, a more productive discussion is concrete: Is a delivery entrance out of sight? Are tools left in a detached garage? Does a shop have trouble keeping track of staff access? Would a useful recording help resolve an incident? Those questions help select the right mix of physical locks, detection and cameras while keeping the budget focused on useful coverage.
A river-town property can have more than one kind of loss
Exeter publishes C-RiSe flood and infrastructure maps to support planning. Flood exposure varies by parcel, and a planning map should not be used to declare that a specific property will flood. During a walkthrough, ask about actual basement water history, plumbing equipment and places where a leak could remain unnoticed.
A leak sensor near a vulnerable water heater, laundry area or mechanical space can add a useful alert. A low-temperature alert may help an owner discover a heating problem while away. Neither replaces maintenance or the person who responds, so decide what should happen when a notification arrives.
Also ask what keeps working when the internet or power fails. Panel communication, app access and camera recording can have different dependencies. Backup arrangements should match the functions you rely on most.
Keep the system easy to own
The cheapest installation is not always the least expensive system to maintain. Count the devices requiring batteries, consider whether any need a ladder to reach, and ask how recordings and access permissions are managed. In a finished historic property, cable routing and careful installation can be a larger part of the price than the panel itself.
An existing-alarm assessment can show what is worth retaining. If you are starting from scratch, the home security cost calculator offers an initial residential estimate. The final recommendation should explain the protected openings, monitoring, camera views and expected service needs in plain language.
Businesses changing door access should also consider the Exeter commercial fire alarm requirements affecting the renovation. For another Seacoast property, see Hampton security systems and Seabrook security systems, or return to our New Hampshire service hub.
Exeter security questions
Can you add security to an Exeter historic home without opening every wall?
Often, yes. We can assess existing cable and suitable wireless devices, then choose the best route for each area. Exterior changes may need historic-district review, and wireless performance should be checked in the actual building.
Can a family member help manage the alarm remotely?
Compatible systems can provide separate authorized app access and notifications. We will discuss who should be able to arm, view activity or manage users, rather than sharing the owner’s login. Remote access is most useful when someone can also act on an alert.
Does a camera over the door need historic approval?
Ask Exeter’s Historic District Commission if the property lies in a local historic district. The town requires review for qualifying exterior changes; the proposed mounting, visibility and materials should be discussed before installation.
