"Someone was in our backyard last night. Our Ring didn't catch anything."

"Garage broken into. We have cameras on the front but nothing on the side of the house."

"Police said there's been a string of break-ins in our area. They're coming through back fences."

These aren't random posts. This is a pattern. And when I see these reports, as someone who has designed security for a living, the same thought hits me every single time: these people had cameras. The cameras just weren't pointing at the right places.

Local news covers this constantly. "Burglar caught on doorbell camera." Great headline. But read the actual story. The burglar was caught on camera walking up to the door. Then they walked around the side of the house and broke in through a window or back door. The doorbell camera gave the homeowner a false sense of security. And that false sense of security is exactly what the burglar was counting on.

Here's what twelve years of reviewing incident reports, working with police investigators, and analyzing security footage taught me.

A doorbell camera covers roughly 10 to 15 percent of your property's vulnerable perimeter. That's the front door and a small slice of the front walkway. That's it.

The other 85%? Your backyard. Your side gates. The back of your garage. The sliding door. The first-floor windows on the side of the house. These areas sit in total darkness at night, completely unmonitored and unrecorded.

Criminals are not stupid. They see the doorbell camera. Every third house has one now. They don't care. They walk around the side, check the gate, and go to work on the back where there's zero coverage, zero lighting, and zero witnesses.

I've seen this pattern hundreds of times. The crime happens in the blind spot. The homeowner shows police a doorbell recording of an empty front porch. And the case goes cold.

I've worked alongside law enforcement for over a decade. I've sat in rooms where detectives review home security footage after a break-in. And the frustration is palpable.

The homeowner hands over their Ring or Nest footage. The detective pulls it up. And 9 times out of 10, it's one of two things: either the camera didn't capture the actual entry point, or the footage is so dark and grainy that you can't identify anyone in it.

Officers I've spoken with say the same thing: "If the footage can't show us a face, a license plate, or something identifiable, it's essentially useless in court."

Think about that. You spent hundreds of dollars on a security camera, plus $10 to $45 a month on a cloud subscription, and when you actually need it, the police can't even use the footage.

This is the dirty secret of the home security industry. The cameras look good on your front door. They make you feel protected. But when something actually happens, the footage fails the two tests that matter: Did it capture the crime? Can you identify who did it?

For doorbell cameras, the answer to both is almost always no.

Here's where this gets uncomfortable. The big security companies know everything I just told you. They have access to the same FBI data. They've seen the same incident reports. They know that doorbell cameras don't cover the areas where crimes actually happen.

So why don't they sell you a solution that actually covers your whole property?

Because their business model doesn't work that way.

Ring, Nest, and ADT are subscription businesses. The camera is the entry point. The real money is the $10 to $45 per month you pay to access your own footage on the cloud. Ring's parent company, Amazon, made over $1.8 billion from Ring subscriptions alone. That's not hardware revenue. That's people paying monthly to watch their front porch.

If they sold you a complete solution that actually secured your property with local storage and no fees, you'd buy it once and never come back. No recurring revenue. No subscription. No lock-in.

The longer you feel just safe enough, the longer you keep paying.

The obvious answer is to install more cameras around your property. Cover the blind spots. Simple, right? Not quite.

Outdoor cameras require drilling into your exterior walls, running cables, weatherproofing, and in most cases, professional installation. Budget $150 to $250 per camera plus $500 or more for installation. For a typical home that needs 3 to 4 extra angles, you're looking at $1,000 to $1,500 before a single month of subscription fees.

And if you rent? Forget it. Your landlord isn't going to let you drill holes in their property.

What about regular indoor cameras pointed through windows? I've tested this dozens of times. Standard infrared night vision bounces straight off the glass and creates a complete white-out glare. Completely useless after dark, which is exactly when 65% of break-ins happen.

This is the gap the industry doesn't want solved. Because as long as you can't cheaply cover your blind spots, you're stuck paying for their monitoring plans and hoping for the best.

But a few years ago, I found something that changed everything about how I approach residential security.

The Thrumina 2K Window Security Camera mounts on the inside of any window. That's the entire breakthrough.

It sticks to the glass from inside your home. Protected from weather. Protected from tampering. Completely out of reach from anyone outside. While recording everything happening on the other side of the glass in crystal clear 2K resolution with full-color AI night vision.

No infrared glare. No white-out. The night vision technology works through glass without bouncing back. You get sharp footage of faces, clothing, license plates, and details that actually help police identify someone. Even in total darkness.

I tested every window camera on the market before recommending this to a single client. This is the one I installed in my own home first. Then my brother's home. Then I started recommending it to every client I work with, regardless of budget.

Because it works. And it costs less than a single month of some people's monitoring subscriptions.

Most security cameras give you grainy, pixelated footage at night. The kind where you can tell someone was there, but you couldn't pick them out of a lineup if your life depended on it.

The Thrumina uses AI-powered full-color night vision that doesn't rely on infrared. That's the key difference. No glass glare. No washed-out images. No guessing at shadows.

You see faces. Clothing colors. License plates. Tattoos. Shoe brands. The kind of details that actually lead to an arrest.

I've sat in police briefings where detectives said, word for word, that better camera quality would double their clearance rate on property crimes. The Thrumina's 2K resolution solves that problem completely.

False alarms destroy trust in security systems. You get pinged every time a car drives by or a leaf blows across the frame. After a few weeks, you stop checking the notifications. And that's when something real happens and you miss it.

Thrumina's AI motion detection distinguishes between routine movement and actual threats. It learns the difference between your dog crossing the yard and a person climbing your fence. It alerts your phone in real time, only when it matters.

I'm in bed. I get a notification. I tap my phone and I can see exactly what's happening on any side of my house. Live. In full color. In the dark. From my pillow.

That's the difference between hoping you're safe and knowing you're safe.

This is where the big security companies make their real money. The camera is the bait. The monthly subscription is the trap.

Ring charges $12.99 a month for their Plus plan. Nest charges $12 a month for Aware Plus. ADT's monitoring plans start at $28.99 a month and go up from there. And what are you paying for? The privilege of watching your own security footage on their cloud servers.

Thrumina records to a local micro SD card. Free 16GB card included, supports up to 128GB. Your footage stays on your property. No cloud servers. No monthly fees. No company holding your recordings hostage behind a paywall.

Over 5 years, the average Ring customer spends $780 just on subscription fees on top of the hardware. Thrumina costs $49.99 once. That's it. Forever.
