Personal security--
The answer is subjective and depends on what the person is trying to feel secure from. You can be tracked and you can bet I believe our government is not beyond using this information for nefarious ways. Used to be they needed a warrant, but not anymore, all under the names Homeland security, terrorism, and the Patriot act.
I have reason not to trust the feds. 12 months investigation based on 2 anonymous letters. See, that is all they need for proof to track you. In my case, I do not keep up with all the neat smart phone technology just for that reason.
You may say, you have nothing to hide. I will not get into all the capabilities that are current or planned in the future technology.
There are many cell phones with video camera capabilities nowadays. Although the video quality might not be what you would like it to be. You may find these phones at your local wireless provider's shop, or at retailers like Best Buy.
People who are looking for affordable security cameras that are also easy to use should install wireless surveillance cameras. These cameras eliminate the lengthy cables and wires that are used in traditional home security cameras. In fact, standard cameras literally have hundreds of feet of wires. Wireless surveillance cameras use the same type of technology as routers, such as 2.4 GHz frequency for transmitting signals. However, the biggest concern with wireless cameras is interference with other wireless devices including routers and cordless phones.
