What can be done with motion sensors, security systems, how outdated are they?

Question

Arduino

Hello.
I have a grandfather, a very cool engineer, who once said let's stir up a startup) - I will make controllers, and you will program them (a tracking system in the house). He can easily make them, and I'm studying Big Data at the moment.
He worked in this area for a long time, and after retirement he received orders, then he stopped ...
I look at him and feel guilty, he has all the equipment and spare parts, a set and contacts, maybe it’s really possible to really launch something ...
I want to I began to understand how much the technologies used to assemble, for example, video door eyes for 5 years, have changed?

Answer 1

Well, how can I say ... Everything is switching to digital and, in general, the same analog eyes / cameras as they were 3 years ago, and now they work the same way, except that the resolution has increased, the interference has decreased (in general)
But in the digital version, everything changes , earlier the same volumetric volumetric sensor was connected by cable to the "brains", but now it more often has its own brains, autonomous power supply, and wireless communication facilities. Ordinary IP cameras now have enough brains to detect motion, transmit a video stream in parallel, and connect to the Internet to send notifications.
Everyone is trying to make "smart" devices.
In security systems, just do a little chaos, a dozen interaction protocols, various central devices. Now it is fashionable to take ready-made home security kits, for example, Xiaomi offers to buy a head unit and any security sensors (all wireless) and connect home automation there: controlled sockets, thermostats, lamps, etc. And don't worry about compatibility

Answer 2

home tracking system

Who will follow whom: are you following your grandfather or is your grandfather following you?
But seriously, I propose a simple system. Gerkon on the door. After opening (if the system is armed, it means that a person enters and does not exit), it is necessary to attach a key fob (card) to the reader within 1 minute (30 seconds, choose the time). Otherwise, an SMS about hacking is sent to the owner (you can also turn on the siren and flashing light).

Answer 3

Everything flows, everything changes.
5 years ago AVR and PIC were popular, now they are slowly being replaced by ARM.
As for sensors, limit switches have not changed much over the past 50 years, at least the principle of operation

Answer 4

Master machine vision with your grandfather, he has a lot of applications and there is a future.

Answer 5

IMHO there are changes, but not so significant that it was impossible to understand them. It is quite realistic to do something like this, I think under certain conditions the demand for "household" automation will be quite good.

Answer 6

no. became clear. it's unrealistic.
grandfather was unrealistically passionate about his work and is now passionate about building what breaks, fixing and ... but I need to help my grandmother and rake.
I can’t love him, but it’s clear that everyday life wins. it's a pity that many minds of that generation are almost never used, but perhaps it could be interesting,
one hope for me and future work,
thanks.

Answer 7

Grandfather needs to quickly break stereotypes and study new technologies, tools and the modern market of microelectronics and components. We need to decide on the suppliers of these components, establish good logistics, and not order parts from China. It is necessary to observe the culture of development, to study new concepts in electronics design, to try to do less "loose" in the presence of integrated solutions, to strive for the overall integration of components.
A lot has changed in electronics in 5 years, you need to keep abreast of news in the background, pay attention to promising solutions and developments. There are, of course, many branches that update more slowly.
If both of you are ready for such decisive alterations, then you can try, he is the brain in Africa too.
Alas, one cannot create a viable marketable product, for example, as the only mastered technology, but one can become a scientist. Translating technological advances into something tangible requires the efforts of different people.
