Key points:
- Remote barn (1km+) with no internet, only mobile.
- 2 entry points: door && gate.
- Detect intruders -> send SMS/call && send video to a remote server.
Setup:
- Raspberry Pi 4 or 5.
- Door sensors (Zigbee/LTE)
- Night camera
- GSM/LTE-M module
- BLE/Zigbee button
Life cycle:
Shutdown detection on off-hours (hours where there's no need to act upon detection). Generally, between 7 am and 7 pm.
When movement is detected by the BLE/Zigbee sensor, the Raspberry Pi should receive the notification and then in parallel do the following:
- send an SMS message/make a phone call to my mobile phone (or my parents)
- start taking an X-second video with a night camera, then compress the video and send it to a remote server that I control
- start playing some siren sounds in an external sound system
Other considerations:
- Local BLE/Zigbee button for system control.
- Remote system stop capability.
Questions:
1. Raspberry Pi 4 or 5? I'm considering at least 2GB RAM for video processing. Is it enough/too much?
2. Small (64GB) M2 SATA or NVME SSD. Recommendations?
3. Zigbee or BLE for the door sensors? The walls to the secondary door have +-50cm thickness and the door is ~8 meters from the place I'm thinking of placing the Raspberry Pi. I've read about some interference between Wifi/USB3 modules and Zigbee but don't know how much of a problem this is.
4. Night camera recommendations?
5. Considering an LTE-M module. Any recommendations?
Appreciate overall recommendations and feedback on the system's design and potential improvements or flaws.
