9 Essential Security Upgrades For Side Doors And Back Entries For Empty Nesters

As the kids move out and your home transitions into a quieter, more personal space, it is natural to look at your property with fresh eyes. While the front door gets the lion’s share of attention, it is the side entries and back doors that present the most enticing targets for intruders. Securing these vulnerable secondary access points allows you to travel, focus on hobbies, and enjoy your home with total peace of mind.

Why Secondary Entries Need Better Security Now

Side alleys, walk-out basements, and back patios are shielded from street view, making them the most common entry points for home break-ins. When a home transitions to an empty nest, daily routines shift; you might spend more time in a dedicated upstairs craft room or traveling for weeks at a time. A standard lock on a back door simply is not enough when an intruder has the cover of darkness and privacy to work against it.

Upgrading these entryways does not mean turning your home into a fortress or dealing with overly complex technology. Instead, it is about implementing smart, physical, and digital layers that work together to deter intruders before they even touch the door handle. Modern security upgrades are designed to integrate seamlessly into a relaxed lifestyle, offering automated protection that runs quietly in the background.

With the right combination of physical reinforcement and smart alerts, you can eliminate the anxiety of “did I lock the back door?” forever. These upgrades are practical, highly effective, and easy to manage once set up. Let us look at the essential tools that will secure your secondary doors and keep your home safe.

Smart Lock – Schlage Encode Wi-Fi Deadbolt

A side or back door is often the preferred entry point for utility workers, pet sitters, or visiting family. A smart lock eliminates the need to hide vulnerable physical keys under doormats or flowerpots, replacing them with secure, temporary digital access codes. It acts as the primary gatekeeper for your secondary entries, ensuring the door is always locked when it should be.

The Schlage Encode Wi-Fi Deadbolt is the premier choice for this task because of its exceptional build quality and hassle-free connectivity. Unlike older smart locks that require a separate plug-in hub, this unit connects directly to your home’s Wi-Fi network. It features a robust BHMA Grade 1 security rating—the highest residential standard available—meaning it can withstand significant physical force.

• Key Specs: Built-in Wi-Fi, stores up to 100 access codes, built-in alarm sensor, works with Alexa and Google Assistant.
• Door Compatibility: Fits standard doors with a thickness of 1-3/8 inches to 1-3/4 inches.
• Power Source: 4 AA batteries (included).

Before purchasing, ensure your side door has a standard deadbolt prep with a 2-3/8 inch or 2-3/4 inch backset. Keep in mind that heavy battery usage can occur if your Wi-Fi signal is weak near the door, so a Wi-Fi extender may be necessary for distant back entries. This lock is perfect for homeowners who want top-tier physical security and easy remote access management, but it is not ideal for those who prefer a purely mechanical system with zero technology.

Video Doorbell – Ring Video Doorbell Plus

Many side doors face gates or driveways where deliveries are dropped off or where uninvited visitors might linger. A video doorbell on a secondary entrance extends your field of vision to these neglected areas, allowing you to screen visitors without opening the door. It serves as both an active visual deterrent and a reliable communication tool.

The Ring Video Doorbell Plus stands out because of its expanded 1536p HD Head-to-Toe video feed. This wide vertical view is critical for side entries, as it allows you to see packages left directly on the ground and detect anyone attempting to crouch out of sight. The battery-powered design means you can install it on any door frame without worrying about existing doorbell wiring.

• Key Specs: 1536p HD Video, Head-to-Toe view, Color Night Vision, Two-Way Talk.
• Connectivity: 2.4 GHz wireless internet connection.
• Power Source: Quick-release rechargeable battery pack (can be hardwired).

Keep in mind that accessing video history and receiving specific package detection alerts requires a monthly Ring Protect subscription. You will also need to remove and charge the battery every few months, though purchasing a spare battery makes this swap seamless. This product is ideal for those who want a clear view of their doorstep and package drops, but it is not the right fit if you want to avoid recurring subscription fees.

Motion Floodlight – Ring Floodlight Cam Plus

Intruders rely on the cover of darkness to target side alleys and back patios without being seen. A motion-activated floodlight strips away this advantage by instantly bathing the area in bright light the moment movement is detected. Adding an integrated camera to this light source ensures you capture high-definition footage of any suspicious activity.

The Ring Floodlight Cam Plus combines two powerful 2,000-lumen LED floodlights with a 1080p HD security camera. Its motion detection zones are highly customizable, allowing you to ignore passing cars on a side street while focusing strictly on your property line. The built-in 105-decibel siren can be triggered remotely from your phone if you spot an active trespasser.

• Key Specs: Dual 2,000-lumen LEDs, 1080p HD video, 140-degree field of view, customizable motion zones.
• Installation: Requires hardwired mounting to an existing outdoor electrical box.
• Smart Integration: Fully compatible with the Ring app and Echo devices.

Because this unit requires hardwiring, you must have an existing outdoor light fixture or hire an electrician to run power to the desired location. The unit is physically larger than standard lights, so ensure you have enough clearance on your siding or trim. It is the ultimate choice for securing dark, wide-open backyards, but it is not suitable for renters or those who cannot perform basic electrical installation.

Security Bar – Buddybar Security Door Jammer

Electronic security is excellent, but heavy-duty physical resistance is what actually stops a motivated intruder from kicking in a door. A security bar wedged under the door handle utilizes the strength of your floor to brace the door shut. It provides a simple, bulletproof layer of defense when you are sleeping or traveling.

The Buddybar Security Door Jammer is far superior to cheap, flimsy alternatives because it is constructed from 16-gauge powder-coated steel. It is engineered to withstand up to 8,200 pounds of force, meaning the door or frame will give way long before this bar does. The thick, non-slip rubber foot ensures a solid grip on carpet, tile, hardwood, or concrete without scratching the surface.

• Key Specs: 16-gauge steel construction, adjustable length from 36 to 51 inches, weighs 8.2 pounds.
• Floor Compatibility: Works on carpet, wood, tile, and concrete.
• Portability: Easily moves between doors as needed.

This is a strictly manual device, meaning you must set it in place when you are inside the house and remove it before you leave. Because of its robust, heavy-weight design, it requires a small amount of physical effort to adjust and position correctly. It is a must-have for maximum physical security on service doors at night, but it is not practical for doors you use frequently throughout the day.

Reinforcement Kit – Door Armor Max Combo Set

Standard door frames are made of soft wood that easily splits under a single, well-placed kick. A door reinforcement kit encases the weak points of the door and frame in solid steel, distributing the force of an impact across the entire wall structure. It is the single most cost-effective way to prevent kick-ins on out-of-sight back doors.

The Door Armor Max Combo Set is the gold standard for physical reinforcement. It includes a 48-inch door jamb shield, two hinge shields, and two door max covers made of galvanized steel. This comprehensive design reinforces the three main failure points: the strike plate, the hinges, and the door edge itself, making the entry virtually impenetrable to blunt force.

• Key Specs: Made of 16-gauge galvanized steel, white finish (paintable), includes 3.5-inch heavy-duty screws.
• Compatibility: Fits standard 1-3/4 inch doors with any lock spacing.
• Testing: Passed extensive police and laboratory testing against kick-ins.

Installation requires a power drill and about 20 to 30 minutes of time. You must check that the clearance between your door and the frame is at least the thickness of a nickel, or the steel plates may cause the door to stick when closing. This kit is essential for anyone with a wooden exterior door frame, but it is not necessary for heavy commercial steel doors or metal frames.

Glass Break Sensor – Ring Glass Break Sensor

Back doors often feature decorative glass panes, or sit adjacent to large windows that can be quietly shattered to reach inside and turn the deadbolt. Standard motion sensors or contact sensors will not trigger if the glass is broken but the door remains closed. A dedicated glass break sensor fills this critical gap in your security perimeter.

The Ring Glass Break Sensor uses advanced acoustic micro-technology to listen for the specific frequency of shattering glass. It ignores everyday sounds like television audio, clinking glasses, or a dropped plate, virtually eliminating frustrating false alarms. With a 25-foot range, a single sensor can protect multiple windows or glass panels in a single room or entryway.

• Key Specs: 25-foot detection radius, battery-powered (3 AA batteries included), dual-stage glass break analysis.
• Mounting Options: Can be mounted on walls or ceilings.
• System Requirement: Requires the Ring Alarm or Ring Alarm Pro Base Station.

This sensor is not a standalone device; it must be paired with a Ring Alarm system to send alerts to your phone. It should be mounted with a clear line of sight to the glass, avoiding heavy curtains or blinds that might muffle the sound of a break. It is ideal for homes with French doors or large sliding glass entries, but it is useless if you do not already own or plan to buy a Ring home security hub.

Security Camera – Arlo Pro 5S 2K Spotlight

Keeping an eye on the expansive area of a backyard, detached garage, or side walkway requires a camera with high resolution and flexible placement. A wire-free outdoor camera lets you monitor these zones in real-time, sending smart alerts to your device before an intruder reaches the door. It provides the visual confirmation you need when you are away from home.

The Arlo Pro 5S 2K Spotlight is an outstanding camera due to its crystal-clear 2K HDR video resolution and powerful color night vision. It operates on dual-band Wi-Fi, which automatically switches between 2.4 GHz and 5 GHz networks to maintain a strong connection even at the edge of your property. The integrated spotlight automatically illuminates the immediate area when motion is detected.

• Key Specs: 2K HDR video, 160-degree viewing angle, color night vision, integrated spotlight, rechargeable battery.
• Connectivity: Dual-band Wi-Fi (2.4 GHz and 5 GHz).
• Weather Resistance: IP65-rated to withstand rain, snow, and heat.

To access advanced features like cloud storage, person detection, and activity zones, you will need an Arlo Secure subscription. While the battery is long-lasting, heavy motion traffic will drain it faster, making an optional solar panel accessory a smart add-on for high-up mounts. This camera is perfect for those seeking high-definition video detail and wide-area coverage, but it is less suited for those who want local storage without paying monthly fees.

Patio Door Lock – Securityman Sliding Door Bar

Sliding glass patio doors are notoriously easy to breach because their factory latches are often flimsy and easily pried open. An adjustable security bar placed in the inner track physically blocks the door from sliding along its rails. It acts as a highly visible, mechanical stop that deters opportunists at a glance.

The Securityman Sliding Door Bar is built from high-grade iron and adjusts easily to fit almost any sliding patio door. It features a dual-function design: it can be mounted inside the track as a physical block, or mounted at chest height on the frame to prevent kids or intruders from sliding the door. When not in use, it simply folds up against the frame out of the way.

• Key Specs: Adjusts from 19 to 51 inches, high-grade iron construction, includes a child-proof anti-lift lock.
• Installation: Mounts into the door frame using included screws.
• Design: Folds down/up for easy operation.

Because this bar screws directly into your sliding door frame, some light drilling is required for installation. It is critical to measure your door track length to ensure it falls within the 19 to 51-inch range before ordering. This bar is an excellent, reliable solution for standard sliding glass doors, but it will not work on swinging French doors.

Door Sensor – YoLink Outdoor Contact Sensor

If you have a side gate, a detached garage service door, or an outdoor shed, standard indoor sensors will not survive the elements. An outdoor-rated contact sensor alerts you the instant a perimeter entry point is opened. This early warning system lets you react before an intruder ever reaches the main house doors.

The YoLink Outdoor Contact Sensor utilizes LoRa (Long Range) wireless technology, giving it an incredible transmission range of up to 1/4 mile from the hub. It features an IP67 weatherproof rating, meaning it can survive heavy rain, snow, and extreme temperatures without skipping a beat. The low power consumption means the batteries can last up to five years before needing a replacement.

• Key Specs: LoRa wireless technology (up to 1,320 feet range), IP67 weatherproof, 5-year battery life.
• Mounting: Includes screws and double-sided heavy-duty tape.
• App Integration: Sends real-time push notifications to your smartphone.

This sensor requires the YoLink Hub to connect to your home network and send alerts. While the sensor itself is incredibly rugged, the magnetic contact must be aligned precisely within 0.78 inches for accurate open/close readings. It is the absolute best choice for distant gates, outbuildings, and exterior barn doors, but it is not necessary for doors that sit close to your main Wi-Fi router.

Simple Installation Steps for Solid Reinforcement

Installing physical upgrades like the Door Armor Max or the Securityman Sliding Door Bar is straightforward, but taking your time ensures maximum strength. Start by clearing any debris from the door frame and checking the clearance around the door edge. A tight fit means you will need to adjust the placement of metal plates slightly to avoid binding.

When installing long wood screws into your door frame, always drill pilot holes first using a drill bit slightly smaller than the screw shank. This prevents the old, dry wood of your home’s structural studs from splitting when the heavy-duty 3.5-inch screws are driven in. Use a high-quality drill driver to sink the screws fully flush so they do not catch on the door.

For smart locks and video doorbells, check your Wi-Fi signal strength at the installation site using your smartphone before mounting the hardware. If the signal is weak, consider plugging in a Wi-Fi extender inside the house, close to that outer wall, before finalizing the setup. Testing the digital connection first saves you the frustration of mounting a device only to find it cannot connect to your network.

Maintaining Your New Safety Habits Effortlessly

The secret to long-term home security is creating simple routines that do not feel like chores. Start by setting up automatic locking schedules on your Schlage Encode smart lock so it secures itself at 9:00 PM every night, even if you forget. Pair this with a quick glance at your smartphone app before bed to confirm all sensors are closed and armed.

Keep your battery-powered devices running smoothly by putting a recurring reminder on your digital calendar every six months. Check the battery levels for your video doorbell, outdoor cameras, and contact sensors all at once, charging or replacing them before they drop low enough to compromise security. Keeping a spare, pre-charged rechargeable battery on hand reduces camera downtime to just a few seconds.

Finally, do a quick physical sweep of your side and back entries every spring and autumn. Ensure tree branches or bushes have not grown to block the view of your cameras or motion floodlights. Wipe down the camera lenses with a microfiber cloth, clear any dirt out of the sliding door tracks, and verify that the security bars still fit snugly and operate smoothly.

With these nine targeted security upgrades, your secondary entries will no longer be the weak links in your home’s defense. By combining physical steel reinforcement with smart, responsive monitoring, you can step out your front door with the confidence that your home is safe, secure, and running beautifully in your absence.
