6 Reasons to set up a motion activated web-cam
- Maybe you live in a questionable (at best) part of East Vancouver and you’ve already been broken into (while you were doing the dishes). It would be helpful next time to have pictures of the intruder.
- Maybe you’re trying to prove to your landlord that some of the more questionable members of the general East Vancouver public are using the pathway between your building and the one next door as a shortcut between streets. Often with very large bags of cans (it’s a Vancouver thing). Loudly. At all hours of the day and night.
- Perhaps you want to catch someone using your PC after you’ve asked them repeatedly not to use it (because they seem to go out of their way to install spyware, toolbars you don’t want, and leave behind Britney Spears mp3s on your desktop)
- You’re bored?
- You want to get pictures of the pretty birdies eating from your new bird feeder.
- Yeah I know what you were expecting here, that’s lewd. Get your mind out of the gutter, this is a family site.
For this tutorial you’ll need:
- a PC running Windows 98, ME, 2000, XP (the software is untested on Windows 95 and NT, but should work)
- a webcam (or two, see advanced)
- Dorgem – an open source (free) webcam utility. Update: Though Dorgem has been discontinued, the download links still work, as does the software. The author will not be updating it anymore, and won’t be answering email support questions.
To upload images ‘off-site’ (in case someone steals your computer) you’ll need an FTP account. See the Advanced section when you’re done the initial setup.
- Install (if it isn’t already) your webcam. If you’re pulling one out of the closet and have long since lost the install CD, here are links to download the drivers for some of the most common webcam vendors:
- Download and install Dorgem. The installation is very straight forward, you’ll mostly click Next a bunch of times.
- Launch Dorgem and select your Webcam from the Camera selection drop-down list.
- Click the Preview button to display the view your webcam has. Physically adjust the camera to face the area you want to monitor.
- Click the Source button and make any adjustments to the Brightness, Contrast and/or other settings. Click OK when you’re happy with the results.
- Click the Options button
- Place a check in the box labeled Use motion detection. Certain Webcams (most often Labtec) can require Dorgem to “reconnect” after a certain period of no motion being detected. For now leave this box unchecked. If you notice that your Webcam isn’t capturing any images even though it should have, revisit this section and place a check in the box. It should be noted that if you do need to use this setting, your cam will likely take a picture every time Dorgem “reconnects” to it, so try using 5 minute (or higher) intervals. Otherwise you’ll end out with a LOT of pictures, most of which won’t have captured actual “motion”.
- Click OK after you have enabled motion detection to return to the main Dorgem window. Now you’ll need to create a ‘profile’ – which Dorgem refers to as Storage events. Click the Store settings button to create an event.
- Choose File and click OK (adding an FTP event is covered in the Advanced section, set a local file first to make sure everything works)
- Enter a Name: for this event, make sure Enable is checked, and then set an interval. Since you’ll be using motion detection, you probably want to capture images fairly “closely together” – so try 1 or 2 seconds. If you know for certain that this camera will detect a lot of motion (your camera faces an area with a lot of movement) you may want to set this somewhat higher. This setting can always be changed later, so experiment a bit. Click the … button next to Filename:
- Here you’ll be setting the folder to save images to, and the actual filename for each image. Dorgem allows special characters in file names so that each name is unique (otherwise each time your camera detected motion it would take a picture and over-write the previous one). Somewhere in the file name, enter the characters %g – which will give your file name a time-stamp. If you use %G in the file name, it will also add the current year.
Because my camera is taking pictures of movement on my patio, I named the file patio-camera%G%g. This results with images being saved as patio-camera20060926165001.jpg. Broken down that’s patio-camera – the current year – the current month, day, hour, minute and second. Click Save after you’ve selected a folder and file name.
- Click OK
- Click Close to return to the main Dorgem widow
- Wave your hand in front of the camera. Or throw something within its view. Jump around in front of it like an idiot. If everything was set correctly, you should now have some images in the folder you specified. Go take a look..
- If it didn’t work, start again at step 3 and double-check everything. The built-in Help file included with Dorgem is actually pretty helpful – use it for troubleshooting. Feel free to leave a comment below and include as much info as possible and I’ll try to help as well.
Multiple Webcams
If you can get more than one Webcam to work in Windows (not always an easy task, esp. if they’re Labtec), Dorgem can support them all. You don’t need to install another copy of Dorgem, but you do need to start each instance differently. To do so, follow the steps below..
- Right-click on your current Dorgem desktop icon and select Create Shortcut
- You should see a new Dorgem (2) icon on your desktop – right-click on it this time, and choose Properties
- Make sure the Shortcut tab is selected, and change the Target: to:
“C:\Program Files\Dorgem\Dorgem.exe” /c:cam2
If you installed Dorgem to somewhere other than the default location, make the appropriate changes.
- Click Apply and then
Sending pictures to a remote location (FTP)
If you’re using this as a personal security system for your residence, you may want to store the files off-site, in case someone steals your computer (rendering your security totally useless). To do so, follow these steps.. (note: you’ll need an FTP account – check to see if your ISP provides one for you, eg. Personal Web Space/storage).
- Click the Store settings button and then click Add.
- This time select FTP and then click OK
- Enter in the required information. The file name can use special characters (see step 11 in the first How part of this tutorial). You may have to experiment with some of these settings. For example, I have to use Passive mode because of the way my home network is set up. You may not. Click OKwhen all of the required info has been entered.
- Wave your hand in front of the webcam (or throw something through its field of view). Check your FTP site and you should see a new file (or files) there. Note: when I have both save to my local hard drive and save to FTP enabled, only one works. You may need to disable the local copy if you want FTP to work. If you figure out a way for both to work, by all means let me know.
How to duct tape the light off your webcam (super-stealth)
- Does your webcam have an annoying light that gives away its location when you try to hide it?
- Find some duct tape that matches the colour of your camera. Or, masking tape and a marker.
- Place tape over the light.
- Your camera will now blend in like a ninja. Extra bonus: use the duct tape to hold your hidden camera in place.
Examples (from the first day I set this up)
Yes, birds will trigger the motion sensing webcam.
Seriously, this isn’t a shortcut for you to use.
How patio furniture gets stolen.
I don’t care if you’re practicing your tight-rope walking, stop using this area as a shortcut.
You too.
My webcam lets me know when not to open my blinds. AKA get an unrequested view of some carpenters crotch.

Thank you – after discovering my boyfriend’s mother in our bedroom when I came home unexpectedly at lunch, I now have a way to check whether she is a repeat offender.

Indeed, that is a great tool. For me I combine its usage with DropBox (2Go free) which automatically synchronize a files between different laptop/network. So when, I am at work, I can be notified instantly if there is any move at home. Please use (more…)

THANK YOU!!!! If I only read your post a couple of weeks ago the Police would have had proofs of the Fu..kers that stole my PC. Do you know if it can store both in an external drive and in an FTP root? It would be great to have a backup in the case the internet is down or they also steal my external drive.
Can someone please help and give me advice please, as to whether it is illegal to record someone on webcam without their knowledge/consent?
This is great!
Just to let you know I am the developer of a piece of software called TeboCam which does the same thing as Dorgem plus you can set the sensitivity by training the program to recognise movement (and avaoid birds triggering the webcam).
TeboCam is fairly feature rich (even now includes a web publishing tool for all you webcam publishers) and is free although it is not open source as I want to keep the rights to the software.
TeboCam is still in development, there have been some 18,000 dowloads in the four months since I released it.
My user community drives the development of TeboCam so please give it a go and let me know how you find it

Thank you for your time.
I wonder if you can help me. A friend gave me a security cam and it has a s-video cord.. I’m wanting to set it up to view outside. I already am using a creative web cam on my PC. Is it poss to set this cam up to my PC using a s-video port. I understand I may not have sound, thats alright.It worked fine on TV using s-video cord but it will not work on my PC. Is there a download I need to run this.
Please, I truly need your help
Great tutorial. I can’t wait to try it out. Even if this software doesn’t work out for me, I can always find another free software that’s similar to this one. Life is good.
Thanks for the wonderful and simple tutorial.
