Q. I need to stay at my parent’s home while my father is recovering from heart surgery. I would like to set up a surveillance system so I can see what the kids are doing back at my home. Can I use Webcams to watch the interior?
A. Sure, Webcams can be used for this. However, you will need software that can handle multiple cameras. You also want features like motion detection, audio and remote streaming. Visit www.komando.com/news for a free program that will help. Note that Webcams usually have poor low-light performance. USB gadgets are also limited to about 16 feet of cable. To go longer, you need to mess with hubs or wireless bridges. You might consider a dedicated security system instead. It will be easier to set up and use.
Q. I am looking for a new job. I know that prospective employers will search for me online. How can I remove my Facebook profile from public searches?
A. By default, your Facebook profile shows up in Facebook and Google searches. That can be dangerous to your job search. Fortunately, you can turn this off, if you know where to look. Sign in to your account. Then click Account>>Privacy Settings. At the bottom, find the Applications and Web sites area. Click the Edit Settings link. Then go to Public Search and click Edit Settings. Uncheck the Enable Public Search option. Your profile won’t show up in Facebook or Google searches. If your kids are on Facebook, you should set this option for them.
