There are a wide variety of security devices that you can use to protect your home and family, from finger print locks to trip wires. Many devices which could only be seen in movies in the past now have become a reality. Even better, the prices have also dropped over the years.
One of the most popular security gadgets today is spy camera. Depending on the type of the camera, you can choose to have professional installation or set it up yourself. However, many can be installed in minutes. Even multiple wireless spy cams can be installed easily.
Wireless spy cameras make use of radio frequency to transmit the images/videos captured. Many of them come with a built-in transmitter. The source of power comes from batteries and/or AC adaptor. Just make sure the camera is well powered and then connect the receiver to your TV set which has been set to a specific channel.
There are also wireless spy cameras with a rechargable battery. Such devices can be found in the form of a cellphone. People will not recognize that the cellphone is actually a wireless camera. With this type of camera there is no need to perform batter replacement. Another advantage of using such dummy cellphones is its mobility.
Spy cameras are available in various forms, from pens to sunglasses. These types of camera are very suitable for you who want to use a hidden camera when travelling. Normally such kits cost a few hundred dollars. However you may be able to find the ones cheaper in the market.
The maximum distance where the receiver is still be able to catch the videos transmitted should also be considered. Normally, the maximum distance between the camera and its receiver is about 30 metres (without obstruction).
There are also spy cameras which come with a built-in digital video recorder. The advantage of using such cameras are that their presence are harder to detect. You can of course purchase a spy camera and a recorder separately.
Another thing to consider is the audio feature that allows for both sound and video recording. Notice that not all of spy cameras are capable to transmit audio signals. Frequency transmitted (e.g. 1.2 or 2.4 GHZ) and resolution are some other things that you should think about in order to find a spy camera that will fit your needs.
The beauty of spy cameras today is you can connect them to a PC to extend its functionality. If you install a surveillance software on your PC you can even perform remote monitoring and surveillance via internet without having to spend much money. This way, your PC also acts as a video recorder.
A spy cam can be a great investment for home protection. In the market you can find the ones which are hidden in various things, from penholder to clock. However you can try to hide the camera in other common stuffs such as inside a doll or a wall picture. It depends on what you want to accomplish.

By: amcnreject | 27-03-2008
My question is about a Digital Video Disc Recorder. If you have recorded three shows and put them as three different titles. When one is done playing should it play the second or should it return to the disc menu? If it continues to play the second, does anyone know how to program it to always return to the disc menu after playing a title?

Simple Video Editing Software to Resize Files With
By: OrenB | 17-07-2007
I'm looking for a simple video editing software, preferably open-source, that allows me to resize a video file (in resolution, not length). I tried VirtualDub but I couldn't find how resize files with it, and SUPER, which gave very poor results (the file size was too big and the colors were very poor). I also tried Kino on Ubuntu 7.10, but it didn't work at all -- probably because I installed this development release too early, I should have stayed with a stable one :-\Other ideas are most welcome. Thanks.
