Re: How to make N900's camera a spycam(video recording while screen is locked)?

Could probably do it with gstreamer, look at recording video to file.

Re: How to make N900's camera a spycam(video recording while screen is locked)?

theres also the problem of the little red light at the back while recording (it can be fixed with live focus)
i dont think there is an app for spy recording right now, but what you could do is just cover the screen with a black piece of paper :D

You need a wireless connection, ssh and gstreamer-tools on N900, and VLC mediaplayer on PC (and probably a lawyer if you aren't whether sure you're performing hidden surveillance with proper authority)

The following example is performed with the following settings. You may customerize them for your own use:

Wireless network: Bluetooth-PAN
IP address of PC: 192.168.1.99
IP address of N900: 192.168.1.1
TCP port for streaming: 5354

1 Installation
1.1 Install gstreamer-tools in N900 if you haven't done so

Code:

apt-get install gstreamer-tools

1.2 Install VLC Mediaplayer on client side if you haven't done so (google search for vlc download)

2 Server-side setup
2.1 SSH to your N900. Start the streaming server as user:

Code:

gst-launch v4l2camsrc device=/dev/video0 ! \

                   dsph264enc ! \

                   rtph264pay ! \

                   udpsink host=192.168.1.99 port=5354

3 Client-side setup
3.1 Create a .sdp file with the follwoing content:

Code:

v=0

m=video 5354 RTP/AVP 96

c=IN IP4 192.168.1.1

a=rtpmap:96 H264/90000

3.2 Play this sdp file with VLC

Usual warning on doing above in legal way. I don't want to see the headline tomorrow "Nerd Caught for Illegal Surveillance with the Advices Got from Underground Forum of Cult Device and OS". ;)

Edit: typos

Re: How to make N900's camera a spycam(video recording while screen is locked)?

you can always turn the red light off using "live focus"
good software for live focus while recording. turrning flaash light when making video (isnt possible without live focus)

Re: How to make N900's camera a spy cam(video recording while screen is locked)?

yes i use live focus to hack red led

@ 9000 i want something that could work offline (anyways thanks for your help)

is there any other way to do this???(without using internet 3g or wifi)

there's this concept called multitasking, where software keeps running even when in background. N900 has it.

That could be done. Let me experiment a bit to see if it works properly under N900.

sorry this can not be done with video rec. it puts camera to "stand by" mode and stops rec.(you should have checked it before posting)

Re: How to make N900's camera a spycam(video recording while screen is locked)?

I hope this becomes a reality. I believe the N800 had a program that could motion detect and record. I currently use an old iBook with webcam for home security (motion detects--records video or jpeg--emails file to my phone). When AT&T renders my 2 N900s useless for 3G, I hope there is a program to make them useful as home monitoring devices instead.
