Concept de maison intelligente Idea para un hogar conectado
I’m interested in exploring networks and related projects for my bachelor’s degree. One suggestion was setting up smart home devices, like IP cameras and sensors, which would trigger recordings and send messages via SMS. My project leader thought this might be risky because similar ideas were done before, so I’d aim to make it more affordable and feature-rich. I’m considering starting with basic functions such as lighting control and dimming. The challenge is finding a balance—avoiding over-reliance on platforms like Alexa while still delivering a practical solution. I’m unsure how difficult this would be in real life, but I’d like to have concrete examples or references for my presentation.
The core idea behind cameras detecting motion and saving footage to a NAS revolves around standard NVR and IP camera systems. You can purchase 4MP PoE cameras around 50€ each, a PoE switch for roughly 100€, and then a NAS for storage. The NVR’s firmware typically comes with motion detection features—like email alerts, SNMP, or similar—so you just need an email account to receive notifications. Adding Alexa or similar services adds complexity because most NVRs aren’t built for virtual assistants. A practical approach is to build the setup yourself: use tablets to view recorded footage on the NAS as soon as motion is detected, and connect it to smart home controls like lights or alarms via web interfaces. Many NVRs also send alarm messages directly, making notifications straightforward. Overall, these components can be assembled with reasonable ease.
the entire setup using cameras and triggers is very straightforward, requiring just one Synology NAS and four Raspberry Pi Zero devices each equipped with a camera. the overall expense should be under 500 dollars. a smart home system of this kind resembles what you find in new construction projects—centralized control with individual power lines for lights, sensors, and other components. the challenge lies in connecting everything and ensuring power, which is why it’s mainly used during building new homes. this simplicity also explains why small wireless smart home solutions like Alexa devices thrive; they avoid wiring but offer limited functionality.
I believe your school has some IP capabilities and networking equipment such as PoE switches for cameras. Setting up a NAS shouldn't be too challenging. I'm aiming to skip Alexa and similar services until I’m sure everything else works. Once I have the necessary skills, I’ll explore integrating NVRs—especially since I’ve never heard of this before. That sounds promising. The surveillance and security system is just one component I’m focusing on, along with watching videos for smart lighting and other related tasks that seem straightforward.
The core problem I notice here is what I can add without having to overhaul everything, like replacing all the electrical wiring. Running new Ethernet cables seems to be the only exception since the main goal is functionality rather than perfect aesthetics—so some mess is acceptable. From what I've seen, Philips Hue uses standard bulbs that are controlled via an app (primarily Wi-Fi), but overall I'm aiming for solutions that work with PoE.
The situation becomes clearer if you consider POE; it would naturally prompt a complete overhaul of the electrical setup. In both scenarios, the goal is to capture a trigger signal from one point and send it to a control unit. For Ethernet, this means all devices must support IP addressing and connect to a central system. Off-the-shelf smart home solutions are preferable here—they typically rely on a straightforward 12V line for triggers, needing only a switch and operating independently of network links.
Hello again, thank you for your message. I appreciate you taking the time to clarify this. From what I’ve seen, it seems like using NVRs is the best approach when you need to monitor more than one camera simultaneously. It’s clear you prefer practical solutions over just watching videos. Regarding your question about recording directly into a NAS, there are a few possibilities: some systems let you record straight into the NVR’s internal storage, while others require a third-party plugin to bridge the gap between the NVR and NAS. As for file formats, most NVRs store recordings in standard video formats like MP4 or AVI, but sometimes they need manual conversion to match your needs. If you want seamless recording to a NAS, it would be helpful if there were examples showing how to set this up together. Let me know if you’d like more details on specific configurations!
For instance, I handle Dahua NVRs and cameras, allowing me to configure both for direct recording to a NAS using FTP, NFS, or other methods. They technically store files in mp4 format, but many need you to save a specific time range before access is possible. The process varies depending on the device.
SmartThings motion/door sensors connect through IFTTT to Blue Iris via webhooks and can activate any action you desire. It’s not a school assignment—I’d say someone familiar with both platforms could set it up quickly, maybe even in an hour. If you’re new to either, a full day might be needed. The key is now that everyday users can achieve what you want using ready-made parts over a weekend. Google voice control functions similarly to Alexa within SmartThings, though Alexa excels at complex routines and voice interactions. Alexa remains the most affordable voice input option, which explains its popularity. Under the Echos, there are many choices, but behind the scenes you have various options. The simplest choice is SmartThings, while more advanced setups can use OpenHAB or HomeAssistant.io. The most straightforward solutions are closed systems tied to specific brands like Apple, Philips, Nest, Echo Plus, etc., though they often lack broad compatibility with other devices.
