I'm trying to figure out if it would be feasible to build a hidden camera out of the following stuff:
>old tv/ac remote to use as shell
>camera sensor in place of the IR diode
>raspberry pi zero with wifi adapter
>old phone battery + makeshift transformer (cheaper for me) / usb power bank (more bulky and expensive)

I would like to hide it in a random pile of stuff on a bookshelf, and I can't afford to have it plugged to a wall charger. This would be an ideal usage scenario:
>want to take a peek
>send Wake-On-Lan trigger via wifi and connect to the camera via vnc or whatever else
>turn off the pi when I don't need it anymore
>...
>retrieve the remote-cam when the battery runs dry
>charge the battery and place the remote somewhere else

I did some research but I can't figure out if the raspberry pi zero is able to wake from a turned-off/stand-by state via wifi.

Also, can Anon give me random ideas/suggestions?

Easily doable if you don't want the remote to work, still possible with a working remote. I'm surprised this doesn't exist off the shelf.

What happens when someone picks up the remote to try to use it though?

it does already exist, but where I live the only way to get it is to have it shipped from China. It would take literally months and it's not exactly cheap. Furthermore, it wouldn't be accessible via wi-fi.

I'm planning to put it in a messy place, where it should add to the heaps of stuff already there. I don't really think that someone would try to use it, and even if they were to do it, they would simply think that the remote is not working and they would put it back where it was. Probably by the wrong end for me to look, but at least it wouldn't be a dead giveaway.

I also thought about simply laying the raspberry + camera somewhere in the mess without any shell at all, since most people don't know how a camera sensor looks like, it would only seem a bunch of cables and electronic stuff. Still, it would be something that could catch the eye more easily than, say, a tv remote.

At the moment my main worries are about the setup's battery life, and the ability to turn the device on through the wifi network.

that doesn't look like something that I could remotely turn on and off whenever I want.

Some kind of home surveillance. I have the feeling that one of my flat mates is doing strange stuff in our kitchen while nobody's there.

>>1235559
I'm quite a noob, I wouldn't know what to do with that. Why should I prefer it to a Pi Zero W + camera + power bank?

>> No.1235569

What if flatmate shuts down the Wi-Fi while dicking around in the kitchen?

Oh you clever motherfucker

Maybe install a hidden sensor in the fridge to count the times the door opens, then check the count against your own count

the raspberry pi doesn't support wake on lan period. As long as it's plugged into power it's on. Now if you can retrieve it, why do you need wifi? You could get a tiny camera that records to a microsd card.

Could you use pi zero but it's crazy overkill and it takes way more power and boot time - just to operate a switch. Ud still need something to switch on the camera with regardless (transistor, relay, bilateral switch) . I dunno how ud fit all that in a remote, but the esp8266 is the size of a postage stamp. I use the 12e.

Lurk and read more.

>something that I could remotely turn on and off whenever I want.

if you drop this silly requirement, then an entire world of cheap, high-quality, spy products can be used which can be set to record only when it detects motion. just go in once in a while to change the battery and replace the SD card with a blank one.

>> No.1235857

Just get a spycam that has motion detection. In addition to having a long runtime due to motion detection, you can fill the rest of the remote control with addition batteries for mega capacity. I don't particularly see the need for wifi of manually turning the camera on or off. If you get a really good spycam, you can configure the sensitivity, time to turn off, etc...
