I like this time of year, a chance to reflect on the last 12 months and take stock of accomplishments and realise the achievements. And something I like to gauge a success on is the longevity of a solution, and a time-lapse comparison 6 months apart is seemingly my go to example.
To elaborate on this achievement, earlier this year was the setup of a homebrew CCTV solution using an array of Raspberry Pi’s with cameras, and a VM Cent OS server acting as a PVR host. A surplus Pi W Zero was pointed at the hills and used as a time-lapse experiment.
The real achievement is that since its conception in early June,
it has been stable enough to run in the background, capturing footage for such an
So here I present my latest time-lapse, a split screen video on the difference between a June day and a December day:
Its been a year since my time-lapse post, and since my server has been working away without external input capturing and archiving the view from from my window the entire time.
Something I wanted to capture is a time-lapse of of summer and winter from the same perspective, in order to see the difference between the two polar seasons in terms of sunlight.
Now with a year’s worth of capture and as a tribute to the reliability of the code, I thought to quickly splice together a June and December time lapse video:
Its interesting to see how the webcam when left at the default settings interprets light values over a sustained period of time. As even in the summer it will get as dark as the winter night at some point, I thought of this as a natural reset point for the cam’s light values.
Choosing a similar weather conditions at both ends of the daylight spectrum (23/06 and 19/12) the camera seemingly registers a different light strength.
Anyways it is still an interesting watch regardless of the date its being viewed at, hope you enjoy, and wishing you a happy new year!
A while ago I worked on a simple CCTV system for work, which involved using software to capture images every second then batch convert them to video every five minutes. It was crude but did the job.
I also dabbled in the past with time lapse videos, however this was a more manual process with images capturing to a folder, then personally loading them into Windows Movie Maker to create the video. With the tedium of creating the videos, the software I used for capturing (YAWCam) would hang after a few weeks constant running, not to mention without upkeep, the hundreds of thousands of image files populating the hard drive.
As a project it was time to combine the learnings from these and create an automated time lapse video creator, a program that would capture images, then create a 5-minute video that contains the days’ footage, and finish by deleting the temporary images to leave just the days video.
