Security Gadgets to Protect Yourself and Your Family some bullet cameras will even have an infrared LED feature built-in. You can determine the resolution by the cameras TVL datum. If you are concerned that large intimidating cameras might make people uncomfortable, consider using smaller cameras or hidden ones. Board Cameras are basically a fixed lens mounted on a circuit board. Once again, before buying a CCTV system or a spy camera it is always wise to consult a professional. This type of surveillance system is extremely efficient in monitoring large crowds in real-time. CCTV stands for Closed Circuit Television. On the other hand color cameras offer more realistic and natural pictures. In some systems you can also find a special monitor.

Many people are under the misconception that a personal computer with additional hardware installed, will do the job. It can be your new alarm clock or pillow, but not a teddy bear (unless of course furry stuffed animals are a common sight in your bedroom). We strongly suggest having a DVR recorder in your CCTV system. Add to that the risk of tampering or damage to the cables, and you have a strong case for wireless. Types of IR Illuminators Once again, before buying a CCTV system or a spy camera it is always wise to consult a professional. 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. Monitoring software could always be updated and you can always add more memory space. Any camera installation will require proper wiring. CCTV security cameras produce images using CMOS or CCD (Charge Couple Device) chips.

for professional installation, security monitors are as important as cameras. They offer extended life to a picture tube (necessary with any static picture, that can cause picture burnout) and much better resolution. Therefore many customers shopping for complete CCTV monitoring and recording systems are confused by such a veriaty of available products.
