we all use home security cameras, they give us footage. lots of it. but footage is not security. footage is evidence after something already happened. unless you’re actively watching it.
and, the tech has evolved, most smart cameras today are reactive. they record everything, send us notifications for every thing, every delivery person, every cat that walks by. you get alerts, you check your phone, you check the video, and decide if it matters. sometimes it might even be silly that you’re watching the video of a random dude walking by.
the best security cameras out there, the nest cams, the ring doorbells, the arlo systems, they're good at what they do. they record in high quality. they have night vision. they have motion sensors. they connect to your phone. but they're still just watching and recording. sending you notifications for every single movement.
and this home guard is a tiny advancement for these.
it's smarter. something that processes what it sees and tells us what matters.
cameras and motion sensors read metallic movement, posture, the way someone carries themselves. if there is a likely weapon, you get a clear alert inside the house. an actionable signal so you can lock doors, call for help, or step out and stay safe.
the point is speed and clarity. notice danger early. act faster.
I’m not quite sure of to what extent that it makes sense but the tech already exist but haven’t gone wide spread. there are lot of places where cameras like these are already in use.
and to build this, these are what we’d probably need
hardware:
high resolution cameras with wide field of view, covering entry points.
motion sensors that detect metallic objects.
posture recognition tech, the kind that reads body language and movement patterns.
edge processing unit, all analysis happens locally, no cloud delay.
alert system inside the house, visual and audio, immediate and clear.
software:
computer vision models trained on threat detection. (lot available on hugging face)
pattern recognition for repeat visitors vs new faces.
real time processing and a very low latency.
smart filtering, only alerts that matter, no noise.
integration with door locks, lights, emergency contacts.
the app (mobile/web):
live view when you need it.
alert history with context.
settings for sensitivity levels, you decide what counts as suspicious.
emergency contacts integration, one tap to notify or call.
zone customization, which areas to monitor more closely.
**the ideal things it should have:**
instant threat assessment, no lag between detection and alert.
low false positives, shouldn't cry wolf every time someone walks by.
privacy first architecture, all processing on device, no footage sent to cloud unless you choose to.
works offline, doesn't need internet to function, only to send you alerts remotely.
simple installation, no complex wiring or setup.
weatherproof and durable, handles outdoor conditions.
integrates with existing smart home systems without friction.
the individual technology pieces already exist today, and the real spark will be in combining all those pieces and assembling them together with a nice user centered design.
and as the usage of AI becomes more mainstream and getting embedded into most of our daily aspects, security would also obviously mature to much smarter systems.
note: i’m no expert in building security systems. i could be wrong.
happy to get corrected. just tell my agent on the right.
