How Do Infrared Illuminators Work? CCTV specs For larger areas or for real-time monitoring you will probably need to add cameras, monitors and other special devices. If things are going bump in the night, there's no reason you can't watch them. Of course, WCCTV cameras aren't cheap (they range anywhere from about $50 to over $600), but considering the money you save on installation and maintenance-not to mention the quality and convenience of long-distance wireless surveillance-a wireless camera is well worth the investment. Hard drives are smaller and more convenient to maintain than VCRs. Special brackets and tile clamps can support a camera destined to be located in difficult positions. Many people are under the misconception that a personal computer with additional hardware installed, will do the job. Buying Tips Something to note, if you have a laptop rental and plan to use wireless accessories be sure to ask if the equipment is wireless capable.
These days, you can get motion detectors, telecentric lenses, and high-resolution digital. For example, why use cameras with 500 TV lines of resolution with a monitor that offers only 380 or less.
Pinhole lens cameras are often called "spy" cameras and may be mounted in a concealed way for covert surveillance purposes. When choosing a camera you'll have to consider two more aspects: the viewable image size and your preference of B/W or color. Many wireless cameras are basically board cameras with built-in transmitters. Board cameras are sold as plain circuit boards, for integrating into hidden camera devices. The larger the number of TV lines, the better the resolution and hence, overall picture quality. The plug and play cables are easy enough to install by non-experienced users. With crime on the rise in more areas than most of us would like to imagine, most are not aware of the many many ways one can use the current innovations in security to protect you and your family without spending a fortune.

Each group differs from the other by means of function and size, although some features are shared by both groups. We recommend this type of security cameras for commercial installations. There are three main types of IR illuminators: diodes, lamps, and lasers. Diodes are small, inexpensive, and good for short-range illumination. They also require relatively little power to operate. Infrared lamps are more expensive to buy and maintain, but they can operate at greater distances and are often better for facial identification. Lasers are excellent for long-range image clarity, even in inclement weather, but they're big, expensive, and potentially harmful to the eye if not handled correctly-which is why they're usually only reserved for military use. A receiver locates the signals the transmitter sends and translates them into viewable images.
CCTV systems Because wireless cameras don't use cables, they're portable, low-maintenance, and easy to install.
