Watch Bob from Rutland, MA Comments

Bob is looking for a good security camera with nightvision that he can monitor over the Internet. Which ones are the best for the money? Leo has a few choices, but he suggests checking for security issues because some are easily hacked. Here are Bob's options:

  • DropCam
    Leo likes these cameras. They're constantly on, and there's also a DVR capability that's available for a monthly fee.
  • VueZone
    These are battery powered so Bob could place them anywhere. The downside is that they aren't constantly on -- only when he accesses it. It can be set up for motion control though.
  • Axis
    These offer pan/tilt/zoom features that can be controlled over the internet.
  • FosCam
    This is a favorite among the chatroom.
Watch Andrew from Rochester, MI Comments

Roger wants an HDTV that he can use for gaming, and he needs it to have low latency. Leo says that the key feature is response time. Old style TV sets had a response time of virtually zero, which is why they're still the best option. LCDs are about 4 milleseconds, which isn't bad, but it does give some motion blur. Latency has to do with connectivity. If he can turn off processing, he'll get better performance.

The chatroom suggests going over to to learn more about specific TVs and what they're display lag is. They also have a great article called The Best HDTVs for Gaming. The best overall is the 2013 Sony KDL-55W900A.

Watch Theresa from Long Beach, CA Comments

Theresa dual boots her iMac with Parallels, and is wondering if she needs to have a backup of each operating system separately. Leo says she does not, if she's running the other operating system in Parallels. If she was using Boot Camp to run each operating system natively on her Mac, then she would need to have separate backups. When she runs Windows in Parallels, it's actually running within OS X. That means, when OS X backs up, so does her installation of Windows.

She's also wondering about AntiVirus. Leo says that a virtual version of Windows is sandboxed, so if she did get a virus, she can just throw away the virtual install of Windows and start over. It won't harm the rest of her system.

Watch Sundeep from Orlando, FL Comments

Sundeep is a physician, and he needs to upgrade his computers, but he's concerned that his current SSD drives won't be secure if he replaces them. Can he erase them securely? Leo says that's a genuine concern. While some claim there are erasers out there, Steve Gibson of GRC says SSD drive data is never really erased, just overwritten. That's why using whole drive encryption from the very beginning is key to protect that data. If he accesses the data on his smartphone, then he'll need to use the harder encryption, not just the simple 4 number code.

Sundeep also wants to know what the best settings are for his HDTV at home. Leo says to use the movie mode, not the dynamic mode. Dynamic is ideal for the show room floor, but for home, movie mode is best. If he wants to calibrate his HDTV, then Leo recommends Digital Video Essentials by Joe Kane.

Watch Anne from Woodland Hills, CA Comments

Anne's cellphone is now off contract and she wants to know what new phone she should get for T-Mobile. She's been using a Samsung Galaxy SII.

Leo says that T-Mobile has dumped the subsidized contract in favor of either buying the phone up front or financing it. Leo says to go to and click on Plans. Scroll down to the Pay as you go plan. There's a $30 a month unlimited data and text plan with 100 minutes a month. It's a great deal if she doesn't spend much time on the phone.

Leo says that the Samsung Galaxy SIII or the SIV is what Anne wants for her phone. The SIV has a ton of bloatware on it though. However, the phone itself is excellent. Leo also says that the Motorola Moto-X is fantastic, and it's a pure Google phone, so it won't have that bloatware. Google just dropped the price of the Nexus 4 by $100, so it's just $200 now.

If Anne can wait a few weeks, the next two weeks will show a host of new phones coming out. The IFA conference in Berlin usually has a ton of new phone announcements, including the Samsung Galaxy Note III. And Apple will announce a new iPhone (most likely) on September 10.

Watch Stan from Woodland Hills, CA Comments

Stan's wife has an iPhone 5, which is their first computer. They don't really know how to use it, though. What's the best book to get to read? Leo recommends going to the Apple Store and taking their "one to one" course. They'll sit down and show them how to use the phone. Leo says that's the best way to start. Books can be confusing because technology is moving faster than publishers can keep up. If their eyesight isn't that great, that could be an issue with the iPhone, but there's also accessibility features built in that will help.

Watch Nef from San Antonio, TX Comments

Nef's keyboard is suddenly typing strange letter and numbers. Leo says to be sure that the numlock or capslock isn't enabled. Keyboards can also get dirty and that could cause it. Keyboards are dirt cheap, and he can buy one and make sure it's just the keyboard that's wearing out. He can plug it in a different one, and if it works, he'll know his keyboard is going bad.

Before he tosses the keyboard out though, he can actually try running it through the dishwasher to clean it. Understand though, that there's a risk that he'd break it, but a lot of times it works great. He should also make sure not to use the keyboard again until it's completely dry.

Watch Boris from New York, NY Comments

Boris sold his iPad in preparation for the next iPad coming out in September. Leo says there's no guarantee that a new iPad will be out in September, though. It's unclear. Leo says that Boris looking at the Google Nexus 7 is a good idea. It has a better screen, and is only $229. But what about his apps? Leo says that most of the apps available on the iPad have counterparts on Google Play, and it wouldn't cost much to replace them.

It would be great if the iPad Mini came out with a retina display, and there are rumors. They aren't confident rumors, but it's worth waiting a couple weeks at least.

Watch Roger from Gladstone, AL Comments

Roger is thinking of getting rid of his Dell and going with an Apple. He has an iPad already, which he loves, but he's thinking of getting a Mac. It's more expensive, but Leo says it's also a professional grade computer. Since Apple has a smaller market share, there's really no viruses to worry about. If price is the issue, Leo recommends getting a refurbished Mac. Leo only recommends getting a refurbished computer from Apple, though.

What about used? Leo says if he buys used, he'd also buy someone else's problems. He shoulid always buy from the manufacturer so he gets a warranty.

Watch Bob from Riverside, CA Comments

Bob's computer won't wake up from sleep mode. Leo suggests checking the cable, and the video card. Since he used different monitors, and put in a new video card, it has to be a problem with Windows. He says he just installed Windows 7, and that's when it started. When installing Windows, the Microsoft Installer looks at the hardware and decides what power saving features to put in. In particular, the APCI power saving mode may not have been enabled when he upgraded. Leo suggests doing a clean install of Windows. He should back up his data, format the drive, and install Windows again.

Watch Rob from Tarzana, CA Comments

Rob is wondering if there's any danger in using his BlueAnt bluetooth device mounted on his visor. Leo says not at all. Worst case scenario is that it could fly off and hit him on the forehead. There's really no risk with radiation or any other frequency issues.

Watch Joe from Buffalo, NY Comments

Joe used to take his hard drive backups to work with him. When he was laid off, however, they wouldn't let him bring home anything, so he lost his backups. So he advises keeping them somewhere else. Unless you own the company. Leo says that's a very good point since they usually escort you out of the building to make sure you don't take anything company owned. This is also a reason to encrypt backups, just in case. It's also a good idea to send backups to someone else so they are off-site as well.

Watch Martin from Bellflower, CA Comments

Martin got a popup saying he's been infected and he needs to buy a Moneypack card and send it to the FBI. Leo says that's a ransom ware scam. Bad guys rely on users to run software through social engineering. AntiVirus will protect him from everything but himself. If he chooses to install something bad, even if he isn't aware it's bad, he's defeated the AVS protection, and that's what they rely on. The only way to get rid of it is to backup his data, format his hard drive, and reinstall Windows from a known, good source.
