If you are a school bus driver and you have bus surveillance cameras, you know what a blessing they truly are. Equipment that is visible (whether it's actually working or off) has an incredibly large deterrence factor. This doesn't apply to just school buses but all kinds of buses and public transportation.
Infrared Surveillance Cameras or Day/Night Cameras are becoming very popular as business and home security cameras. They provide a full color picture in daytime or adequate light situations. Gradually switching to BW at night or low light to maintain picture quality, Infrared cameras, as their name suggests, contain an array of Infrared LED's that turn on in low light and can provide a B/W picture in complete darkness.
Portable Surveillance cameras are becoming more and more popular these days especially with technology advances yielding smaller and smaller cameras. Generally but not always, the smaller the camera device the easier it is to hide or disguise and the smaller it is the easier it is to make it portable.
Capturing video footage with your digital video camera system is great, but there may be times when audio is also needed. In this case you will more than likely want to have some good surveillance camera microphones.
Today's surveillance camera CCTV systems have made "leaps and bounds" in technological improvements compared to the systems from just 10 to 15 years ago. Not only that, but the camera's prices have steadily decreased with the increase in technology. All of this has lead to video surveillance cameras becoming a "household word" for family protection and safety as well as business protection and workplace documentation.
