Nothing has more “global” access in the digital video security camera industry than an IP (Internet Protocol) security camera. These cameras use the Internet as the means for their transmissions so anyone with a broadband Internet connection and a computer can access these cameras. The outreach available for use and/or monitoring has been extended even further with the increased technology in cell phones, namely 3G and 4G broadband Internet access. In the following article we’ll take a look at some Internet security camera systems and how they work.

Nanny cams are hidden cameras that have been installed in common, every day household items. The camera is used (secretly) to monitor and record the daily activities of home caregivers; hence the name “Nanny Cam.”
A Nanny cam can be used remotely, where it’s video is transmitted by radio waves to a receiver hooked up to other devices (Digital Video Recorders or DVRs, sent over the internet,) or you can use a “hardwire” run which, unless your careful, will more than likely stick out and be easily seen.

Security camera lines of resolution are one of the factors that determine the size, fineness, or quality of a high resolution CCD camera. Most often, this figure is referenced in TVL which stands for Television Lines and is usually used to reference analog type video quality. Digital resolution is usually referenced in terms of pixels. Let’s take a look at both and see how the lines of resolution relate to high resolution CCD camera picture quality.

PTZ or Pan Tilt Zoom Internet cameras have the freedom of mobility to move about a horizontal and vertical axis thereby increasing the field of view for the camera. In fact in some situations one Pan Tilt Zoom Internet camera may be able to perform the work of two or more stationary cameras. In addition, the zoom function allows combinations of lenses to create telephoto enlargements for better clarity of objects that may be too far away from a normal camera lens. These cameras also have the benefit of using the Internet too monitor and control the cameras.

There are certain applications for surveillance and security where a “standard” Digital Video Recorder or DVR is just too large. For these applications the best choice is a micro DVR. Micro DVRs can be so small as to fit inside the casing of an ink pen. Let’s take a look at a digital video system that uses standard size DVRs first, and then take a look at micro DVRs.
A standard DVR is about the size of DVD player. The front of the DVR has buttons and switches to control the actions of the DVR. The back of the DVR is where all the connections are made to cameras and other items.
