Hello,
I'd like to know more details about this project. Is this paper writing or developing project?
If you need this surveillance system to be built, I've done similar things using MQTT broker, also supported by clouds very good for notification and alarms on multiple devices. Also, each device can be used to control the systems.
Also, if you already have project hardware specification please let me know. If you don't have I can help you to make one.
Feel free to check my profile.
Thanks in advance,
Stevan
