I use the Ubiquiti Cameras which are PoE and they work quite well.
(Snapshot example URL: http://192.168.1.95/snap.jpeg)
I have a process on a Raspberry Pi that will grab an image every minute and
saves it to /dev/shm (the ram disk - which saves wear and tear on the SD
card). The image can be viewed via a php webpage grabbing the image from
/dev/shm. See code below for example:
<?php
$content = file_get_contents('/dev/shm/webcam.jpg');
$type = 'image/jpeg';
header('Content-Type:'.$type);
echo $content;
?>
Hope this helps.
