And what about eight digit lock code?

"nice pics" - green dark from small camera and none (shutter closed) from main camera.

Thanks for the stories.


What about debugging it? You might run out of time if thief switches off the device and re-flashes it.

Create a poll. I do use a lock code, even though I'm often angry at having to input it again.

Reward is mostly for case when you genuinely lost the device.
If the device was stolen, you might have to reward a thief in the end (if he is clever enough that he cannot be tracked down for the police).

I don't make backups. I have enough mess without multiple "backup" copies.


The simple way to protect a device against a thief: always have it in your hand (or at least no more than one meter away from you). First, it's difficult to steal it without attracting your attention. Second, you might call the police before he takes the device. Third, other people around might notice it (if he is that stupid). Fourth, if you have a second camera/phone in your pocket/bag, you can photograph him/call the police while he isn't far away.

A clever thief would switch off the device immediately and re-flash it at home and remove the SIM card (and no software would remain on the device to take photographs/GPS coordinates/etc). And lock code, as mentioned, can be circumvented. Then, the only mean to track down the device would be the IMEI code (it's non-trivial to change it), so keep it written down separately. It would be the final proof (when the suspect is found) that the device in question is yours, even if it is unfortunately wiped clean.

Having a software sending information from the device to identify thief is good only for the first moments of theft, until he switches everything off. So, when there is a possibility of theft, leave camera shutter open, and let the device continuously send new information (both camera's photographs and GPS coordinates and connection information) to your server (home computer?) through Wi-Fi/Bluetooth/cellular connection. When there is no theft, just clean up old files from the server; when there is theft, you don't need to turn on a special signal, you just need to stop deleting files from the server. Even if thief switches off the device as soon as possible, you still may have photographs of him coming closer to the device before he takes it.

When you report device as missing, serious thief has already wiped clean the device. That's why the suggestion is to turn logging on not when it is stolen, but when there is high probability to become stolen.

If there are several devices nearby (company of friends), you can set up a Bluetooth sending/receiving ring: A->B->C->A (alarm can be set to sound when a connection fails), so that if one human loses a device, the other one pulls out the photographs and GPS coordinates received from the device and shows where he lost it. Works only if the company walks together all the day long, but it has the advantage of working in subway in absence of Internet and cellular connection.
