Best Home Security Systems for High-Value Homes and Collections

Homes with expensive collections often need more than basic entry-point protection. Art, jewelry, collectibles, firearms and other high-value property may be concentrated in specific rooms, cabinets or safes. That makes it useful to think beyond a single alarm and instead build several layers of protection around the areas that matter most.

Those layers can include entry sensors at doors and windows, motion detection inside the home, cameras near key access points and environmental sensors where water or temperature changes could damage sensitive items.

ADT currently supports all of those functions within its broader security platform, including professional monitoring and cellular backup on qualifying systems. Here are the features worth prioritizing when building a security setup around valuable property.

If you’re protecting a large collection or several high-value areas, ADT can design a system around the home’s layout rather than relying on a standard package.

What Is the Best Security Setup for High-Value Collections?

The strongest setup uses multiple layers of detection rather than relying on a single alarm or camera. Start with the exterior doors and accessible windows. Add interior motion detection around hallways or rooms leading to valuable property, then consider additional sensors around cabinets, storage areas or other restricted spaces (see below).

Another item to consider is ADT’s Premium Door/Window Sensor, which includes shock detection for abrupt or forcible entry attempts. It can also be used on cabinets and drawers containing valuables such as jewelry or cash.

Why It’s Important To Protect the Room Before Focusing on the Safe

A safe is an important physical barrier, but the security system should ideally detect trouble before someone reaches it. A door sensor on the room containing the collection can provide an early alert, while interior motion detection adds another layer if an intruder enters through an unprotected route.

ADT motion detectors can trigger an alarm and smartphone notification when unexpected movement is detected while the system is armed. Sensitivity can also be adjusted based on factors such as pet size. This layered approach is particularly useful for dedicated collection rooms, home offices, workshops and other spaces where valuable property is concentrated.

Can You Put Alarm Sensors on Cabinets and Storage Areas?

Yes, depending on the type of opening and sensor compatibility.

ADT specifically notes that its wireless door/window sensors can also be placed on cabinets, drawers and interior doors, allowing homeowners to monitor access to areas containing personal records, medicine or valuables. The company’s Premium Door/Window Sensor also includes tamper alerts and shock-sensing technology.

For safes themselves, installation depends on its design and sensor configuration. Rather than assuming any contact sensor will work properly on a heavy steel safe, it makes sense to confirm compatibility during installation.

Why Cellular Backup Matters in a High-Value Home

A sophisticated security system isn’t very useful if it loses its communication path during an internet outage. ADT’s current professional monitoring plans include cellular alarm-event backup on qualifying systems. If Wi-Fi disconnects, supported alarm signals can still leave the ADT Base over cellular data or cellular SMS.

The Base and supported security equipment also provide up to 24 hours of battery backup during a power outage. That redundancy is useful for any home, but it becomes more important when the contents being protected are difficult or expensive to replace.

Where Should Security Cameras Go Around Valuable Collections?

Cameras are most useful when they complement sensors rather than replace them. For high-value homes, exterior cameras can cover approaches, driveways and entrances, while indoor cameras may be appropriate in dedicated collection rooms or other areas where privacy isn’t a concern.

ADT’s current wired Google Nest Cam Outdoor records up to 2K video. It offers a 152-degree diagonal field of view and uses encrypted video and two-step verification through the associated Google account.

Camera cybersecurity also deserves attention. The Federal Trade Commission recommends strong, unique passwords, two-factor authentication, current software and WPA2 or WPA3 encryption on the home Wi-Fi network.

Don’t Forget Water and Temperature Damage

Security doesn’t only mean burglary protection. Water leaks and extreme temperatures can pose serious problems for artwork, paper collections, instruments and other sensitive possessions.

ADT’s Water & Temperature Sensor can detect water as well as user-defined hot, warm or cold temperature conditions and send alerts through the ADT+ app. ADT specifically lists basements and attics among potential locations for the sensor.

For a collection stored near plumbing, below-grade spaces or areas with temperature concerns, environmental monitoring may be just as useful as another camera.

Is Professional Monitoring Worth It for High-Value Property?

Professional monitoring provides an additional response path when the homeowner isn’t available to respond to an alarm. That can matter when you’re traveling, asleep or simply away from your phone.

ADT’s professionally monitored systems can send supported alarm events to its monitoring centers, while cellular backup provides an alternate communication path if Wi-Fi is unavailable. For a high-value home, the goal isn’t necessarily to install the largest possible system. It’s to identify where losses would be most significant and build layers of detection around those areas.

That might mean entry sensors around the house, motion protection near a collection room, additional monitoring around cabinets or storage spaces and environmental sensors where heat or water could cause damage.

If you’re protecting art, jewelry, collectibles or other high-value property, ADT can evaluate the home’s entry points, storage areas and connectivity and recommend a customized security setup.
