In this project we will be using the 4G LTE Network and a Radar Human Presence sensor to create a new and modern alarm system. Due to the 4G Network and LTE-M you can send alarm notifications super fast to your phone, while it costs you pretty much nothing. Combine that with a precise radar and loud siren and you got yourself an awesome alarm system that will protect your treasures ;-) Let's get started!

The main issue i see with this is the power dependence.. If a thief cuts your power, this thing turns off. It might be worth it setting up a small UPS inside the case as well for power in the case the power is cut.

7:36 Just a warning, the way you blurred the map location you can easily figure out your exact location, by automatically comparing google maps to the blurred content. You should always use black boxes, or maybe colored pixel noise instead. I can tell it's google maps by the color scheme, and I can tell it's not just noise because the blurred UI elements are where I would expect them to be. But it could easily be done with some Javascript and some image processing.

As somebody who work myself for an international IoT/M2M telecom operator, we have a lot of customers having this kind of setup (although still with 2G.... so props for using LTE-M). I'd recommend to make some check on the device so that it's always connected to the cloud or that it can atleast ping it. Due to technical maintenance on the cells we send a "CancelLocation" event to disconnect the SIM and perform works and some devices think they still have a PDP session ongoing and keep trying to send MQTT payload and are stuck behind this loop where the operator already closed the PDP session but the device still sees it being open and uploads data without checking if it's acknowledged. Make sure to once in a while send some TCP type of packets and if they don't succeed then fully reboot the device or send the AT command AT+CFUN to reboot the whole module. It's best to fully reboot reboot the module rather than check if the PDP session is still open and try to reopen it. Also You might try to check the NB-IOT technology it's even more light weight incase you want to use it in an area where there's no electricity and you send data only when the module wakes up (coverage is even better than LTE-M) These are my two cents good luck and great video! :)

Awesome project!!! I want to give few hints regarding radar sensors: 1. you can buy those sensor based on different frequencies. Ensure that the choosen frequency is allowed in you region for your application. Having a wrong radar running might disturb other electronics near by... and at least in Germany you can get serious trouble if someone calls the autorities because you block a certain frequency band. 2. Be aware that radar might be disturbed by any metal. Facing this e.g. to the garage gate might cause some problems. 3. Be aware that the sensor might look through walls 🙂

Yep, more complicated but what modern alarm doesn't have code based security. I don't want to get too much into feature creep but that is a very low cost add on (a 4G receiver/transmitter rather than just a transmitter). And a small lithium ion battery backup. Easy and right down Great Scott's alley. I see an alarm 2 point zero coming.

Great project and nicely done. I would have made one different decision. I can't tell from your video if you turned down the volume when the alarm was on, but it doesn't sound very loud or piercing. If not, I would have scrapped an old smoke alarm for its siren - they are loud, annoying, and would definitely cause intruders to not stick around. Additionally, that flashing alarm is awfully expensive if some of us out here wanted to recreate your project.

You should mount the alarm box in a safe all by itself. Run the wiring for the accessories (sensors, speakers, lights, cameras, microphones, etc.) Out of the bottom or out of the back of the safe. Secure the safe to the floor or the wall, if you can. A burglar could waste so much time on trying to take or to breach that safe. As they waste their time, notifications are being sent, photos, audio recordings, or video could be taken, and sent. Alarms could be making loud noises while strobe lights flash and disorent the intruder. So even if they smashed the speaker or the lights, they still wouldn't be able to stop the notifications or the audio/video recordings from being sent. Another option would be to mount the alarm box in some other location, still use a dummy safe that is either too heavy to move or bolted to the floor or wall, and mount all of the alarm accessories in the areas needed to protect your valuables.

Here in Germany they can't shut down GSM that easily. A lot of stuff depends on GSM and it would be really expensive to replace everything. GSM is used in a lot of alarm systems or fire alarm base stations for larger buildings. Also a lot of older people still use older phones that won't work anymore then. I found out that on a certain point in the next village you still have 3G reception till today although it should be shut down. I don't know why that is the case, but it is a bit weird.

I had a similar system using a PIR sensor. It triggered an led floodlight along with the buzzer from a washing machine. However it kept scaring the locality dogs and cats and kept me awake and sleepless all night with the false alarms

i would remove the switchs on the side, add a pin pad, a battery, paint the box a color that matches the wall, make the sensor the brain and the sciren wireless, so i can hide the the "central", and a heart beat to monitor if everything is okay every seconds otherwise notify aswell but good video :) any plans for the green house ?

Couple of unknown aspects/suggestions: how do you "disarm" it ? Flipping a switch like you show is way too vulnerable for an alarm system (suggestion 1: at the very least, it should have a keypad to punch in a code). Suggestion 2: remote arming/disarming via the phone. Cheers

@cmh-re Жыл бұрын
actually you could had used just a pir sensor facing the entrance. just by opening the door the change in detected ir is enough to trigger, it's damn cheap and it doesn't pick you if you are outside. great project tho. I would suggest moving outside to arm switch to a keyed switch whit tamper protection, outside, so you don't get blasted by the siren every time you open the door

Nice project! I wonder if this siren/led would really distract thiefs especially in a sparsely populated area. Maybe adding some really bright lights in and outside of the garade could draw more attention. Did you also think of adding a camera which makes snapshots in case of a burglary?

I think its a great idea. It would be also pretty easy to add a keypad for code entry. And also maybe integrate smart lightning etc to this same 'box' as well.

My only concern is it looks like you installed it right next to the door with the buttons facing anyone entering. A thief could just hit the off button quick before any detection. Might make more sense to mount it on the backwall facing the door, and trigger a way to disarm it from a text before entering.

Well an awesome project, but there is one point thats really disturbing and thats the on / off switch on the side of the case. What if, in theory, a thief would make it into that garage without triggering the alarm, switches the whole system off and get the whole stuff out of there. As you are using an Arduino tho i think the best way to deactivate the system is a numpad with a special code or a fingerprintsensor or an RFID Card.

Notice that the mosquitto test instance is not guaranteed to be available in any way - it's a test instance only. Also, Android phones love to shutdown or delay background services for battery saving. I wouldn't want to rely on an alarm set up like this. (Sorry for the negativity, but I've been working in IoT long enough)

random thought if you could add manual triggers run a wire to say your bike and use magnets around it as a switch so if the wire is removed without entering a code into the console the alarm activates this idea can be improved on but be a nice manual trigger for more expensive stuff could be used on the door also to just send an alert with option to call police when the door is opened
