When you think about protecting your home or business, what’s the first thing that comes to mind? For most people, it’s the front door or the main entry point. But in reality, intrusions can happen through any door, window, garage, or glass panel—and a strong security system needs to address every possible vulnerability.
At M&M Security, we offer a wide range of devices to secure entry points and detect threats before they escalate. Whether you’re a homeowner looking to safeguard your family or a business protecting people and assets, comprehensive door and window protection is essential.
Let’s break down the devices that make up a well-rounded intrusion detection system—and why they matter.
1. Door and Window Sensors
These are the foundational devices of any security system. Door and window sensors detect when an entry point is opened or closed, immediately alerting the system to any unauthorized access.
Where to Use Them:
- Exterior doors and all ground-floor windows
- Second-floor windows for extra peace of mind
- Entry points in garages, basements, and back doors
Why They Matter:
- Immediate alerts when doors or windows are breached
- Essential for intrusion detection when the property is armed
- Easily integrated into monitored systems for automatic notifications or dispatch
✅ Available in wired or wireless options to suit any installation type
2. Overhead Door Sensors
These specialized sensors are designed to monitor garage doors, roll-up bays, or warehouse entrances—areas that standard sensors can’t always cover effectively.
Perfect for:
- Homes with attached garages
- Commercial buildings with loading docks or storage areas
Why They Matter:
- Overhead entries are often overlooked and vulnerable
- Provides status alerts (open/closed) for high-risk access points
- Can trigger system alarms if the door is opened unexpectedly
3. Glass Break Detectors
While most sensors detect if a window opens, glass break detectors listen for the specific sound frequencies of breaking glass. This gives you an extra layer of protection even if a burglar tries to bypass window sensors by smashing the glass instead of opening it.
Great for:
- Homes or businesses with large glass windows or sliding doors
- Retail storefronts with exposed glass
- Buildings with vulnerable, secluded windows
Why They Matter:
- Detect break-ins that don’t involve opening a window or door
- Fast response with minimal false alarms
- Covers a wide radius, protecting multiple windows in one area
4. Shock Sensors
Shock sensors detect vibrations or impacts on windows, doors, or walls—like someone trying to force their way in or hammer through a weak point.
Ideal for:
- Commercial buildings with rear entrances or metal doors
- Homes with older or reinforced entry points
- Locations that have experienced attempted break-ins in the past
Why They Matter:
- Detects tampering before actual entry occurs
- Adds proactive protection for vulnerable structural areas
- Excellent early warning system when paired with other detectors
5. Motion Detectors
Motion sensors detect movement within a space and are an important backup in case someone bypasses entry sensors altogether.
Types of Motion Sensors:
- Passive Infrared (PIR): Detects body heat
- Dual-Tech: Combines heat and motion for better accuracy
Where to Install:
- Hallways, main rooms, entry points, and office spaces
- Areas with limited foot traffic during closed hours
Why They Matter:
- Wide area coverage inside buildings
- Triggers alarms if motion is detected during armed periods
- Can reduce false alarms with sensitivity adjustments
✅ Offered in both hard-wired and wireless models
6. Indoor and Outdoor Motion Viewers
Motion viewers go one step further by combining motion detection with a built-in camera. When motion is detected, it captures a short video clip and sends it to your phone or monitoring center.
Perfect for:
- Businesses monitoring after-hours activity
- Homeowners who want to visually verify alerts
- High-risk or high-traffic areas where false alarms are more likely
Why They Matter:
- Immediate visual confirmation of events
- Helps verify real emergencies vs. false triggers
- Enhances your system with smart surveillance capability
Seamless System Integration
All of these devices can be tied directly into your monitored security and fire alarm systems, ensuring:
✅ Real-time alerts to your phone or security panel
✅ Optional notifications to monitoring centers or emergency responders
✅ Unified control and visibility under one platform
With customizable zones and sensor combinations, M&M Security designs systems that work exactly how you need them to—whether you’re protecting your family home or a multi-site commercial operation.
Why It’s So Important
1. Burglary Prevention & Early Detection
Entry sensors and motion detectors stop crime before it starts—or catch it the second it happens.
2. Code Compliance & Insurance Requirements
For many businesses, verified security systems are necessary for insurance coverage or code compliance.
