15 Products and Tips to Protect Your House Against Whatever Comes to You
Advertisement
Your house has one job: keep what you love on the inside and everything else on the outside.
Most people protect it backwards. They spend eight hundred dollars on cameras that record a man walking through a door that cost eleven dollars to defeat, and call it a security system. The real threats to an American house rank almost exactly opposite the way we shop for them: water gets in more often than men do, the power goes out more often than either, and the food runs out quietly while everyone watches the front porch.
Fifteen products and the tips that make them work, layer by layer — flood-proofing, water and food that survive an outage, generators and batteries, perimeter detection, hardened doors and locks, and a straight answer on which gun belongs in a house.
Counting down from #15 to #1 ‚and the last pick is the cheapest thing on this list, which is exactly the point.

🔍 How We Screened These 15
It has to work when the power is out. Anything that dies with the grid was cut or paired with a backup that does not.
It has to be installable by the homeowner — or by one electrician in one visit. No contracts, no monthly fees, no subscription holding your own footage hostage.
It has to have a real service record. Every product below is in stock, rated 4.0 stars or better, and most carry thousands of verified reviews.

🌊 #15 → #13 — Water Gets In Long Before Anyone Else Does
Insurers have said the same thing for thirty years: you are far likelier to file a claim for water than for theft or fire. Start here — it is cheap, and it actually gets used.
#15 — Geevon 4-Pack Water Leak Detectors, 100dB Alarm
$24.99 ¬∑ 4 sensors ¬∑ 100 dB alarm ¬∑ 2-year battery ¬∑ no hub or wifi required ¬∑ 4.5★ (3,057 ratings)
Best for: Catching a burst supply line at 2 a.m. before it becomes a $30,000 claim
Every list like this starts with guns and cameras. It should start here. The most likely thing that will ever damage your house is not a man at the door — it is a quarter-inch braided supply line behind the washing machine letting go while you sleep. These drop behind the water heater, under the sink, next to the sump and the furnace, and they scream at a hundred decibels the instant they get wet. Four of them cost less than one hour of a plumber's time, and they buy you the only thing that matters in a leak: minutes.
#14 — Quick Dam Grab & Go Flood Kit, 10-Pack (50 ft of Barrier)
$139.13 ¬∑ 10 barriers ¬∑ 5 ft each (50 ft total) ¬∑ water-activated ¬∑ no sand, no shovel ¬∑ 4.3★ (482 ratings)
Best for: Damming a garage door or basement window when you have twenty minutes of warning
Sandbags require sand, a shovel, a truck, and about two hours you will not have. These are dry, flat, and stack on a shelf in the garage until the creek comes up or the storm drain backs up, then they swell into a barrier the moment water hits them. Fifty feet is enough to seal a garage door, two basement window wells, and a walk-out slider. Buy them in the dry season, because the day the forecast turns is the day every hardware store within forty miles is empty.
#13 — Basement Watchdog Combo Primary + Battery Backup Sump Pump
$469.00 ¬∑ preassembled primary + battery backup ¬∑ dual float switches ¬∑ audible failure alarm ¬∑ 4.5★ (312 ratings)
Best for: The house whose basement floods the same hour the power dies
A sump pump is a single point of failure with your foundation on the other side of it, and the storms that fill your basement are the same storms that take out the power line. This is a preassembled combo: a primary pump for normal duty and a DC backup on its own battery that takes over when the grid drops or the primary quits. It alarms on low battery, on primary failure, and on rising water anyway — the part cheap backups leave out. Buy once and cry once here, because the alternative is a finished basement and an adjuster explaining the difference between flood and seepage.
🥤 #12 → #10 — Water, Food, and Heat That Outlast the Outage
Three days is the number the government plans around — and roughly when the grocery store is empty. Plan for thirty and you never think about three again.
#12 — Big Berkey 2.25 Gallon Gravity Water Filter System
$367.00 ¬∑ 2.25 gal ¬∑ 304 stainless ¬∑ 2 Black Berkey elements ¬∑ gravity-fed, no power, no plumbing ¬∑ 4.4★ (4,218 ratings)
Best for: Turning creek, pond, or boil-notice tap water into drinking water with zero electricity
Municipal water fails in two directions: it stops coming, or it keeps coming and you are told not to drink it. Gravity filtration answers both, because it needs no pressure, no electricity, and no cartridge subscription. The Berkey sits on a counter and pulls creek water, pond water, rain barrel water, or boil-notice tap water through two elements rated for thousands of gallons. It is the most boring purchase in this guide and the one you will use during a normal bad week, not just a catastrophic one.
#11 — Ready Hour 120-Serving Freeze-Dried Entr√©e Bucket
$149.99 ¬∑ 120 servings ¬∑ freeze-dried entr√©es ¬∑ 25-year shelf life ¬∑ sealed bucket ¬∑ 4.6★ (2,718 ratings)
Best for: Thirty days of hot meals that need nothing but water and heat
Long-term food is not about doomsday. It is about the week after a hurricane, an ice storm, or a job loss, when you want to eat something hot without standing in a line. A hundred and twenty entrée servings is roughly a month for one adult or a week-plus for a family of four, and it stores flat in a closet for twenty-five years. Buy an extra bucket every quarter until you have thirty days per person, then stop thinking about it.
#10 — Mr. Heater Big Buddy PRO 18,000 BTU Propane Heater
$146.48 ¬∑ 4,000 / 9,000 / 18,000 BTU ¬∑ heats up to 450 sq ft ¬∑ low-oxygen shutoff ¬∑ tip-over shutoff ¬∑ 4.3★ (3,607 ratings)
Best for: Keeping one room and one family above freezing when the furnace has no power
A house without heat in February becomes uninhabitable faster than a house without food becomes hungry, and furnaces do not run on natural gas alone — they run on electricity for the blower and the igniter. The Big Buddy runs off two one-pound cylinders or, with a hose, a twenty-pound tank, and it is rated for indoor use with both a low-oxygen sensor and a tip-over cutoff. Plan on heating one room, not the house: pick the smallest room with a door, move the family into it, and let the rest of the house go cold. Crack a window an inch anyway — the sensor is a backstop, not a permission slip.
⚡ #9 → #7 — Power When the Grid Quits
Buy the switch before the generator. A generator without a transfer switch is an expensive way to run three extension cords, and a battery without a panel is an expensive flashlight.
#9 — Reliance Controls Pro/Tran 31406CWK 30-Amp 6-Circuit Transfer Switch
$313.65 ¬∑ 30 amp ¬∑ 6 circuits ¬∑ UL listed ¬∑ wattage meters ¬∑ pro install recommended ¬∑ 4.5★ (1,712 ratings)
Best for: Running your furnace, well pump, and fridge off a generator legally and safely
This is the least exciting item on this list and the one that separates people who own a generator from people who can actually use one. A transfer switch wires into your panel so you can power hard-wired loads — furnace, well pump, sump, fridge — by flipping breakers instead of running a spiderweb of extension cords through a cracked door. It also physically prevents backfeeding the utility line, the failure mode that kills linemen and burns houses. Have an electrician install it on a Tuesday in September, not by flashlight in January.
#8 — Westinghouse 12500 Peak Watt Dual-Fuel Home Backup Generator
$1,049.00 ¬∑ 12,500 peak / 9,500 running watts (gas) ¬∑ dual fuel ¬∑ electric start ¬∑ remote start ¬∑ transfer-switch ready ¬∑ 4.4★ (819 ratings)
Best for: Whole-house backup that runs on gas or propane so one fuel shortage can't stop you
Twelve thousand five hundred peak watts is genuine whole-house territory: well pump, furnace, refrigeration, and the freezer in the garage, all at once. Dual fuel is the real reason to buy this over a cheaper single-fuel unit — gasoline goes stale and vanishes from stations during the exact event you bought this for, while propane sits in a tank for a decade and does not care. Pair it with the transfer switch above and a hundred pounds of propane, and a four-day outage becomes an inconvenience instead of an evacuation. Run it outdoors, twenty feet out, exhaust pointed away, every single time.
#7 — EcoFlow DELTA 2 Max 2048Wh Power Station + 400W Solar Panel
$1,549.00 ¬∑ 2,048 Wh LiFePO4 ¬∑ 2,400W AC output ¬∑ 400W solar panel included ¬∑ 3,000+ cycles ¬∑ 4.4★ (368 ratings)
Best for: Silent indoor power that recharges from the sun and never runs out of fuel
A generator is loud, needs fuel, and cannot run indoors. A battery does none of those things, which makes the two complementary rather than redundant. The DELTA 2 Max runs a CPAP, a fridge, the wifi and the cameras, and every phone in the house through the night in silence, then takes the included four-hundred-watt panel back to full during the day. LiFePO4 is the detail worth paying for: three thousand cycles means a decade of camping trips and outages with most of its capacity intact.
👁️ #6 → #4 — Eyes on the Perimeter
Detection beats recording. Recording tells a detective what happened; detection tells you it is happening. Build outward-in: driveway, then door, then whole property.
#6 — eMACROS 1/2-Mile Solar Wireless Driveway Alarm
$49.99 ¬∑ 1/2-mile range ¬∑ solar-powered sensor ¬∑ weatherproof ¬∑ expandable receivers ¬∑ 4.4★ (11,487 ratings)
Best for: Knowing someone turned in off the road before they reach your porch
Cameras tell you what happened. An alarm tells you that something is happening, and that difference is the entire point. This sensor mounts at the end of the driveway or on a gate post, charges itself off the sun, and chimes inside the house the moment a vehicle or a person crosses it. Eleven thousand reviews at four and a half stars is not an accident — it works, it keeps working through winters, and fifty dollars for advance warning is the best money-to-security ratio in this guide.
#5 — eufy Security Video Doorbell E340, Dual Cameras, 2K
$119.98 ¬∑ dual 2K cameras ¬∑ package view ¬∑ local storage ¬∑ wired or battery ¬∑ no subscription required ¬∑ 4.0★ (4,355 ratings)
Best for: Front-door and package-level coverage with local storage and no monthly fee
Most porch cameras see faces and miss everything below the knee, which is where the package, the pry bar, and the dog are. The E340 runs two cameras — one at head height, one aimed down — so you get the person and the doorstep in the same event. It stores locally on the device or on a eufy base station, which means no monthly fee and no footage of your family living on somebody else's server. Hardwire it to the existing doorbell transformer and stop thinking about batteries.
#4 — Reolink RLK8-800B4 8-Channel 4K PoE Camera System with 2TB HDD
$594.99 ¬∑ 8 channels ¬∑ 4K/8MP ¬∑ 4 bullet cameras ¬∑ 2TB HDD included ¬∑ PoE, no subscription ¬∑ 4.4★ (2,220 ratings)
Best for: Wired, cloud-free 4K coverage of every approach to the house
Wifi cameras fail in exactly the moment you need them, because wifi is the first thing an outage takes. Power over Ethernet means one cable per camera carrying both power and video to a recorder in a closet, and that recorder keeps writing whether or not the internet is up. Four 4K bullets cover a typical house: front approach, driveway, back door, and the blind side nobody thinks about until they see the footage. Mount them at eight to ten feet — high enough to be out of reach, low enough to actually identify a face.
🏹 Which Gun Actually Belongs in a House
Most articles dodge this one. There is no single correct home-defense firearm; there is a correct one for your house, your walls, and your training time. Three honest options:
A pump or semi-auto 12-gauge, loaded with #1 or 00 buckshot. The classic answer, and still right for a lot of people: enormous authority, cheap practice ammunition, a manual of arms simple enough to stay learnable. The costs are real — heavy recoil, four to eight rounds before a reload, and buckshot that passes through interior drywall. A 20-gauge gives up very little on target and takes a great deal off your shoulder; if recoil is why a shotgun sits unused in a closet, buy the 20.
An AR-15 carbine in 5.56, loaded with soft-point or bonded defensive ammunition. Counterintuitive to most people; the ballistics are not. Lightweight 5.56 projectiles are more likely to fragment or destabilize in drywall than 00 buckshot or a 9mm round, and you get low recoil plus a magazine that solves the capacity problem. The trade-off is muzzle blast indoors — punishing without hearing protection staged next to the rifle.
A duty-size 9mm handgun. The worst of the three at stopping a threat and the best at being there when you need it, because it is the only one you can carry room to room while you hold a phone or move a child. If you own one gun and it lives in a bedside safe, this is usually it.
The tips that matter more than the caliber argument:
Put a light on it. You cannot defend against what you cannot identify, and most of these scenarios happen in the dark against someone you may recognize. A rail-mounted light such as the Streamlight TLR-1 HL is not an accessory; it is the difference between a defensive shooting and a tragedy.
Know what is behind your walls. Walk the house and map where a missed shot goes — the neighbor's bedroom, your kid's room, the street. That map, not a ballistics chart, picks your load.
Store it locked and staged, not loose and hidden. Hidden is not secured, and a small safe left unanchored is a portable box of guns. Bolt it to the bed frame or a floor joist on the side you can reach without standing up — the only arrangement that satisfies both speed and responsibility, and in a growing number of states, the law.
Train with what you staged. A gun you have not fired in three years is a prop. One box of the actual defensive load you keep chambered, once a year, is the minimum honest standard.
None of the picks below are firearms. What we can help with is the part most people skip: where it lives when you are not holding it.
🔒 #3 → #1 — The Hard Shell and the Last Line
The layer everyone starts with and almost nobody finishes — and the cheapest tier in this guide.
#3 — BILLCONCH Biometric Fingerprint Handgun Safe
$69.99 ¬∑ biometric + keypad + app + key ¬∑ steel body ¬∑ pry-resistant ¬∑ interior LED ¬∑ 4.5★ (6,495 ratings)
Best for: Fast access for you, zero access for a curious eight-year-old
A defensive firearm has two jobs that fight each other: it has to be available to you in four seconds in the dark, and it has to be unavailable to a child, a guest, or a burglar for the other 86,396 seconds of the day. A quick-access safe is how those two jobs stop fighting. Fingerprint opens it in about a second, the keypad works when your hands are wet, and the key gets you in when the battery is dead. Seventy dollars is not a vault and it is not meant to be — it is a defeat-the-opportunist box, and it is the difference between owning a gun responsibly and leaving one in a nightstand drawer.
#2 — Schlage Encode Plus Smart WiFi Deadbolt (Grade 1)
$319.00 ¬∑ ANSI Grade 1 ¬∑ built-in WiFi, no hub ¬∑ Apple Home Key tap-to-unlock ¬∑ 30-code capacity ¬∑ fingerprint-free access log ¬∑ 4.5★ (2,566 ratings)
Best for: Ending the hide-a-key habit and knowing every time a door opens
The hide-a-key under the flowerpot is not a security system, it is a hobby, and everyone who has ever cased a house knows the six places it lives. Grade 1 is the commercial-duty rating — the tier used on storefronts — and this one adds codes you can issue and revoke for the dog sitter, the contractor, and the kid who keeps losing keys. The log tells you when each door opened and whose code did it. Set it to auto-lock, because the most common way a house gets entered is not a broken lock; it is an unlocked one.
#1 — Door Armor MAX 5-Piece Door Reinforcement Kit
$95.99 ¬∑ reinforces jamb, hinges, and strike ¬∑ 3-inch screws into the stud ¬∑ fits standard 36-inch doors ¬∑ install in about an hour ¬∑ 4.7★ (2,071 ratings)
Best for: Stopping the single most common forced entry in America — the kicked front door
Here is the part nobody selling you a camera wants to explain: the deadbolt is not the weak point. The jamb is. A standard jamb is half-inch pine held to the framing by three-quarter-inch screws through a stamped strike plate, and a two-hundred-pound man defeats it in one kick — the bolt stays locked and the wood simply leaves. Door Armor replaces the strike, wraps the jamb in steel, and reinforces the hinge side with three-inch screws that reach past the trim into the actual stud, turning a one-kick door into a several-minute problem that makes noise the whole time. Every other item on this list buys you information. This one buys you time, and time is the only thing that has ever mattered.
🛠️ Three Cheap Upgrades Worth Doing This Weekend
Security window film — BDF S8MC 8-mil safety film (about $64) laminates the glass so a break-in becomes a loud, slow, still-blocked mess instead of one quiet elbow.
A floor-anchored door brace — the OnGARD Security Door Brace (about $90) holds thousands of pounds. Overkill daily, correct for a house alone on a rural road.
Trim the shrubs and add light. Free, and it beats most of what money buys. Burglars are not looking for a challenge; they are looking for cover.
🧮 Which Layer Should You Buy First?
If you have never done anything at all: spend $121 today on the Door Armor MAX and the leak detectors. The two most likely bad days your house will ever have.
If you lose power more than twice a year: buy the transfer switch and the dual-fuel generator together, installed before the season turns.
If you are rural or on a long driveway: detection first. The driveway alarm and the wired 4K system beat another lock, because your response time is measured in minutes, not seconds.
If you have a basement, a crawlspace, or a creek: the battery-backup sump pump is not optional and it is not a project for the week it floods.
❓ Frequently Asked Questions
Is a monitored alarm system better than what is on this list?
Better at one thing — dispatching police when you are away — and worse at nearly everything else. Monitoring cannot stop a door from opening, cannot record with the internet down, and stops the month you stop paying. The layered approach here costs less over three years than most contracts cost in one, and you own it.
Will reinforcing my door and jamb cause a fire-egress or landlord problem?
Reinforcement kits install inside the existing jamb and do not change how the door opens from the inside, so egress is unaffected. Barricade bars and floor braces do restrict exit — nighttime routine only, never on a door a child sleeps behind. If you rent, ask first; most landlords say yes.
Do I really need a transfer switch, or can I just run extension cords?
Cords work for a fridge and a lamp, not for a furnace, a well pump, or a sump — those are hard-wired. And the shortcut people reach for instead, a double-male cord backfeeding a dryer outlet, energizes the utility line outside your house and can kill the lineman restoring your power. Buy the switch.
Generator or battery — if I can only afford one?
Generator, if you have a well, a furnace, or a freezer — runtime is limited only by fuel. Battery, if you need silent indoor power or your outages last hours, not days. They pair well: run the generator twice a day to top the battery, and live off the battery in between.
🏁 The Bottom Line
Door Armor MAX — $95.99. Ninety-six dollars and one afternoon turns the weakest structural point in your house into something that takes minutes and noise to defeat. Nothing else on this list returns as much per dollar, and everyone skips it.
Westinghouse 12500 Dual-Fuel Generator — $1049.00. Paired with the transfer switch, it keeps the furnace running, the well pumping, and the freezer full through the four-day outage that is far likelier than anything involving a stranger at the door.
Harden the door. Keep the water out. Keep the power on. Then worry about who is on the porch — and by then you will already know, because you built the layer that tells you.
