Cover that Webcam, Before you’re a Star!

Webcams, are a subject that I have covered before with friends and family. This is an opportune time to share some of my knowledge, with blogging friends. While they are a great tool in visiting one another during this worldwide shelter-in-place, they can be an embarrassment, perhaps even a danger without the proper precautions. Remember, once somethings out there on the Internet, it’s out there forever.

Why should I be worried

During this time of boredom, you will have kids home from school, others that no longer have to work and have a lot of time on their hands. Some will entertain themselves with video games. Some, will entertain themselves with the sport of hacking into your devices. Most of the time, it is just to see if they can accomplish the exercise of gaining control of something they aren’t supposed to. Thrill of the game type of thing.

Your security is important

Most webcams are plug and play. This is nice for those of us that don’t care for complication in setting up devices. Most, if not all webcams, come preconfigured with “default” user and password settings. They can range from user=admin or simply user=user. Then we have the password. They can generally on the simple side from the factory. Password=password, or Password=(nothing, blank).

If for whatever reason you don’t take the time to change those items of security, then someone may be watching your baby cam, or your home, or seeing whatever the webcam on your desk, or built into your laptop can see. There may be moments, that might be embarrassing. If you do opt to change your password, make it a decent one. There’s no guarantee this will happen to you, but erring on the side of caution is best.

They can do that?

When I bring this subject of webcam security up (which by the way I’m no expert at), the first question is usually,”They can do that? How”. Without getting into the technical geek speak, the method is out there. With Google, you can find “anything”. There are other research types of search engines, that are not generally used by the normal public. These can be used to search for certain “strings” that have to do with webcams that have admin, and password set to default.

]There are the websites that do auto searches using these search engines and compile lists for people who would like to see the world. Some webcams are purposely set, so hotels, or venues can share their beauty or location. These search engines, also find other webcams that have factory set passwords and list them.

Examples for you to see.

There is a site called insecam. While it says that all cameras are filtered as having no password set, or requested to be added to the directory, there have been some spotted that obviously were from laptops and home webcams. Now, there are cameras of birds, aquatic life, locations of beauty, all of them have one thing in common. No password set.

Things to do.

  1. First and foremost, set a password for your webcam, if it is connected to the Internet. If you use it for security, or perhaps video conferencing then it has access to the Internet.
  2. Purchase or make a cover for your webcam. It can be as simple as a post-it note, or piece of frosted scotch tape, or one purchased from online.

This is where I keep my webcam for my desktop. Pointing away toward a wall, when not in use. I use a small piece of post-it or opaque scotch tape for my laptop and tablet (Yes, I’m cheap). If you have questions, or more tips to help others secure their webcams, please share them with everyone.

Something that I enjoy. Time lapse photo/video

I have always enjoyed photography. Certainly by no means a professional, but I still enjoy experimenting. My camera,  an older Canon EOS digital SLR, is aged now. Far out-distanced by modern cameras with special features. It still takes good photos.

I find watching clouds, and other things of the world in compressed time. You can see more detail, secrets and wonders when you are able to watch something change over minutes, instead of hours or days. It never did storm during the 4 hours that the camera monitored the sky, but it appeared imminent.

This was done using my cheap Raspberry Pi 3 computer
The Pi Camera 5 mega pixel
1 Frame/shot/ every 3 seconds.
I produced the movie at 30 frames per second.
I didn’t add any audio/music to this one, but may in the future.

It’s nice to just sit and unwind while watching the clouds. I use a video software player that can vary the speed if I desire. My apologies for the power lines in the video, it was the best shot I had that day. I hope you enjoy the video as I do.

Modifying an old webcam, for infrared imaging.

I ran across this infrared project some time ago, and thought I would like to give it a try. All our cameras have filters in them that filter out most of the infrared spectrum. Removing this filter makes for interesting infrared photography.

First, I located an older spare webcam. Then removed the housing, which was really snapped together well.  I needed access to the camera circuit board. If you’ve never had the opportunity, to see how small the image sensor is, this is your chance.  The small black rectangular object in the center, is the sensor chip.  The lens housing, sits over this and focuses the image onto the sensor. This one also has a small microphone, actually large by today’s standards. In the bottom of the lens housing, is glued a small piece of infrared filter glass. You have to remove it to allow the infrared through. It was stubborn, but I donned my magnifying headpiece, and pictured myself as a mad scientist. I was as careful as possible, but I still broke/chipped the glass square. It not being much larger than the sensor chip, and glued in securely.

Glass filter removed

This is an example from Wikipedia of infrared photography.

 

 

 

 

 

This is what my old webcam produces now. The trees across the way are filling out with leaves. This makes them look less leafy. The shrubs and grass are a rich green. I forgot that infrared light causes a slight focus shift. I need to adjust the focus for clearer pictures.

Time to find another project now.

Have a little Pie with your Internet. Zero calories to boot!

I know many don’t care for technical type posts as a rule, but just in case someone happens to be searching for information on a RaspberryPi, they can see the set up I have made.

I thought I would try one of these small computers that were developed in the UK just a few years ago. They are very small, some can be had for as little as $29 bare bones. I wanted a better one so opted for the newer version. Raspberry Pi 3 B. This one has a quad core processor that runs about 1.2-1.6ghz. It has 1GB of on board memory you share with video. (4) 2.0 USB ports, Wireless, Bluetooth HDMI and Ethernet. A lot packed into a small computer slightly smaller than a playing card. Michelle ordered this for me as a late birthday present. She ordered the deluxe Kit, which is more at around $69 but comes with everything including a fan, and SD card 32GB, HDMI cable, power adapter.

  • 1.2GHz 64-bit quad-core ARMv8 CPU, 1 GB RAM
  • 802.11n Wireless LAN, 10/100Mbps LAN Speed
  • Bluetooth 4.1, Bluetooth Low Energy
  • 4 USB ports, 40 GPIO pins, Full HDMI port, Combined 3.5mm audio jack and composite video
  • Camera interface (CSI), Display interface (DSI), Micro SD card slot (now push-pull rather than push-push), VideoCore IV 3D graphics core.

You can get a kit with everything but the micro SD card, for around $49.

For something to play with it is fun and interesting. Much cheaper than a desktop. It runs  various Linux distributions which are free, the most popular being “Raspian” which is a mix of some Raspberry programs and Debian Linux. You can install Ubuntu or other Linux flavors. It has an HDMI port so you can hook it to a monitor, I don’t have a monitor with HDMI so I am using VNC to connect into it and use my computer monitor. Parts are cheap for the Pi, a simple case around $5-$6, power adapter $8 or cheaper, 32 GB SD card, if you want one that big. $14 at Walmart. The latest Pi with all the above listed features, just the board is $34. Webcam for it that plugs onto the board with short or long ribbon cable is only about $19 for a 5 mp or $26 for an 8 mp! I am going to save up and get me a 5 mp camera. Which brings me to the only shortcoming.

Shortcoming: The only thing I found wrong with it was limited webcams that work with it. It is hit-and-miss. Some super cheap USB cams work, some don’t. Unfortunately, none of my cheap ones work. But I can solve that with a Pi camera for what I pay for a cheap USB cam.

I have posted to the forum from it, after all it is a full Linux computer, just small and not super charged. You won’t do video editing I don’t think (but I bet I try). It has office software, mail, chromium or Firefox browser, just like larger computers. You can install what you want just like from a normal Linux computer.

I got this one to learn on, I wanted something that could run my weather station 24/7 and not use the main computer for that. So this tiny machine can sit on the desk off to itself and happily monitor the weather station and generate the pages and upload them to the website. I am still working on it, Trying out a simpler weather software. Anyway… here are some pictures of it’s size. This one is in a layered clear plastic case, with a tiny fan to cool the CPU. It currently is running wireless on the WiFi here in the house. The pictures and a video may show it with an Ethernet cable. I used that to set up the vnc and configure the wireless. The only cable running to it now is the weather station.

It’s small!! Just un-boxed it.

We have the case assembled and on it now. You can stack them one atop the other with some cases. Note the small, half-dollar size fan.

My car-keys look nearly bigger than the computer.

Future plans: Since it will run 24/7, I plan on

Running the weather station.Setting up a service on it to monitor my websites and alert me by email. Seems my “free” monitoring service, isn’t too reliable notifying me at times.A Time lapse, and picture upload program, for the forum, blog, and Wunderground weather service. It already uploads weather conditions to my Wunderground reporting station every 5 mins. Currently It updates the weather web page of my website every 10 minutes.

It seems to run very snappy for a 1.2-1.6ghz. It is running a server and SQL database, without noticeable lag. It is using about 400mb of the 1GB of memory when running the graphical interface through the monitor, but just running as a machine, it is using about 150mb of memory. Running cool as well. 36c

I scrounged around and found a Blue-tooth keyboard we aren’t using, and a wireless mouse. I stopped by the thrift store last week, there sat a 14 inch monitor for $10. I was pleased to see it worked being just $10.

Now I can say, I have Raspberry Pie (Pi) in my office. I just hope it doesn’t attract ants.
