UltraPro Personal Security Window and Door Alarm, 4 Pack (45174)

Quick take

UltraPro’s window and door alarms are a simple DIY way to detect when a protected entry point opens. Each alarm uses a magnetic sensor and a bright LED low-battery indicator, and you can select either a loud 120 dB siren or a gentler chime. The main catch is mounting and alignment, since the system depends on the magnet and base staying properly positioned.

Pros and cons

Pros

  • Wire-free installation with included double-sided tape for quick placement.
  • Selectable alert style, chime for everyday awareness or alarm for situations that need louder deterrence.
  • Instant alert concept when the door or window separates the magnet and sensor.
  • Battery-operated operation, powered by included LR44 batteries with a low-battery LED indicator.

Cons

  • Magnet alignment depends on your door or frame, some setups may be harder than others.
  • Not a smart, app-based system, so it won’t integrate with phone notifications.
  • Review evidence is limited for long-term reliability, since most buyer comments focus on setup and immediate use.

What buyers think

Reviewed productBuy on Amazon

Buyer feedback points to how quickly these alarms can be put in place and how noticeable the alerts are. Many comments highlight the tape installation being fast and straightforward, with the units working well on bedroom doors, sliding doors, and other interior entry points. The loud alert is repeatedly described as sufficient to get attention during the night, while the chime mode is viewed as useful for gentler day-to-day monitoring. There is also some limited evidence of occasional out-of-the-box issues (for example, one unit not activating immediately), plus a recurring theme that alignment and mounting surfaces can affect whether an installation works cleanly on certain door frames.

How this door and window alarm system works

This is a compact, non-smart alarm kit designed for entry-point awareness. A magnetic sensor pair detects when the door or window opens or closes. When the magnet separates from the sensor, the unit triggers your selected alert type. Each unit includes a switch that lets you choose between chime for lighter alerts or alarm mode for a louder siren-style response.

Installation and everyday usability

The biggest selling point for most shoppers is the no-wiring setup. These alarms mount using included double-sided tape, which is meant to work on doors, windows, cabinets, drawers, and similar surfaces. Because it is tape-based, success depends on surface cleanliness and stable mounting locations. Some buyers also note that achieving proper magnet alignment may require careful placement, particularly when door frames or hardware create an angled or uneven surface.

Alarm vs chime mode

If you want something that does not constantly interrupt daily routines, chime mode is positioned for everyday awareness. If you are securing a more critical opening, alarm mode is the option that delivers a 120 dB audible alert when triggered. This makes it easier to use the same product across rooms with different expectations, for example chime in one area and alarm mode in another.

Battery life and low-battery indication

Reviewed productBuy on Amazon

Each alarm runs on four LR44 batteries (included). There is also a front LED indicator intended to alert you when battery power is low. Practically, that means you can plan replacements before the alarms become silent, rather than discovering the issue only after a trigger.

Who it’s best for

  • People who want a low-cost, DIY way to add audible awareness to common entry points without installing a full system.
  • Households looking to protect night-time movement, such as caregivers and families monitoring bedroom doors and windows.
  • Renters or apartment dwellers who prefer wire-free mounting and do not want app-based smart home monitoring.
  • Anyone who also wants flexibility to place alerts on non-traditional openings like cabinets or drawers.

Who should skip it

  • Shoppers who specifically need smartphone notifications, app control, or integration with other smart devices, since it is not smart-home compatible.
  • Buyers with door or window frames that make magnet alignment difficult. If the geometry prevents the magnet from staying close to the sensor base, the alarm may be harder to use reliably.
  • Anyone expecting a monitored security solution. These alarms are designed for local audible alerts, not professional response.

Pros and cons recap

Reviewed productBuy on Amazon
  • Good fit: tape-on, no-wiring alerts that help you notice openings fast, especially in bedrooms and other high-priority areas.
  • Main tradeoff: correct placement matters. If your door frame prevents clean alignment, you may need a different approach for that specific opening.

Price and availability

UltraPro’s 4-pack is typically positioned as an affordable entry-point alarm option. Check current pricing and availability before ordering, especially if you want to cover multiple rooms since the kit is sold as a bundle.

Alternatives to consider

  • More complete DIY entry sensor kits: If you want the same door/window detection concept but with app alerts or a hub, look for kits designed for smart notifications instead of standalone audible alarms.
  • Camera-first security: If you need video verification of what triggered the alarm, a camera setup may be a better fit than an audible-only detector.
  • Hardwired or monitored systems: If you want professional monitoring or centralized alarms, consider a full system rather than tape-mounted standalone units.

Verdict

Reviewed productBuy on Amazon

The UltraPro 4-pack is a practical choice for adding immediate awareness to doors, windows, and other openings using a simple magnetic sensor and wire-free tape mounting. It’s especially appealing for renters, families, and caregivers who want louder alerts during critical times and a chime option for everyday monitoring. Just plan for placement, because clean alignment between the magnet and sensor is essential for reliable performance.

FAQ

How loud is the alarm?

The audible alarm is rated at 120 dB, and you can switch between chime and alarm modes depending on how noticeable you want the alert to be.

Does this work with a phone app?

No. It is not smart-home compatible and is designed to provide local audible alerts rather than app notifications.

How do you install these alarms?

They use included double-sided tape for tool-free mounting. You attach the alarm base and magnet so they stay aligned, then the unit triggers when the door or window separates the two parts.

What batteries do they use?

They require four LR44 batteries per alarm (included) and include a front LED low-battery indicator.

Will these work on my front door?

They can work well when the magnet and sensor can be mounted on stable, aligned surfaces. Some door frames and angles may make alignment difficult, so it’s worth verifying placement before permanently mounting.
