i ordered several different type on ebay and the first that arrive is this jelly lens:

lg gt540 as a poor man’s security camera

i am finally satisfied re-purposing my old and neglected lg optimus gt540 swift. as mentioned in my previous posts, i installed motion detector as motion detector. it may not be as good as a CCTV system with night vision and infrared (ir) for clear captures with limited light but this setup cost a fraction if none at all.

to obtain the fullest of being a poor man’s device, installing kWS – Android Web Server will do the job. this makes an android phone accessible anywhere (port forwarding and or other configuration may be required).

plain, simple and no root required

drawback is that you will be scrolling a very very long page after a while... (click image to see what i mean)

moving on, i enabled ftp upload in motion detector app to move the captured images to a more viewable web interface. basic goal is to make php file that will: sort the images descending (latest captures shown), option to upload to (google) picasa & flickr and, most importantly, delete to maximize space.

old android phone as security camera part ii

so i ditched RL Watcher because i could not seem to make it work with my lg optimus gt540 swift.

now comes Motion Detector by Jastrzab. one quite powerful app. tons of features including friendly developer and the only one i wanted, ftp upload. the only downvote i find is the maximum image size the app can save. on my gt540, i can only use the app with a maximum image resolution of 640×480 pixels but the application’s maximum is 800×600.

i am now left with one problem before i can deploy my camera. that is, to make it work plugged directly on an outlet but without the battery. i tried to reduce my phones cpu speed down to 480mhz, removed all other applications (especially those that run in the background) but i still could make it run for more than 5 minutes without the battery.

cpu frequency set to 480mhz

…’til then.
