So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

Bullet Security Cameras -- Why Flexibility Matters in CCTV Systems

By Tony Sporando

Bullet cameras are extremely adaptable security cameras and are the bread and butter of the security world. Many have both day/night viewing. The quality of a Bullet Security Camera is based on two metrics: Chip Set and Resolution. The higher the resolution the sharper the video quality. Chip-sets in a bullet security camera range from a quarter inch (1/4") to to a third inch (1/3"). A larger chip-sets means the CCD image processor can take in more light, resulting in better video quality. All these factors play a role in the price and performance of each bullet camera.

In addition to their flexibility, bullet cameras are inconspicuous. They are not obtrusive, ugly cameras. Since bullet security cameras can often fit in your hand, they are know for their smaller sizes. This means that they are light weight, can be installed in smaller areas, and not clunky and thus difficult to install.

Bullet cameras are extremely versatile. They can be used indoors or outdoors. They are generally very tough, and withstand heat, cold, rain, and the snow. Bullet cameras can withstand temperatures 180 degrees Fahrenheit to -20 degrees Celsius, and can even survive hurricane conditions.

Bullet Security Cameras also utilize both color and infrared video capturing methods. Many models have sensors that know when to automatically switch between the two. Infrared cameras are a type of black and white video capture that allows one to see in the dark.

Bullet security camera models also differ by the number of LED lights that they have on them. When picking a model, it is important to know the location that you are going to install it, as bullet security cameras with more than 12 LED lights should not be used indoors as the amount of light that will reflect off of interior walls will wash out the video when it is in infrared mode.

It is also important to not use a bullet camera if you have lots of reflective surfaces (such as shinny objects, large windows, doors with windows, or even sometimes of reflective paint) as this can cause the infrared sensors to malfunction. You do not face any of these restrictions when using these cameras outdoors.

Although most models can be purchased with both types, the other major decision you will need to ask is "What type of lens will I need?" There are two types: fixed and vari-focal lenses. Fixed has one viewing angle, whereas vari-focal allows for multiple angles. Again, what makes bullet security cameras so flexible is that these lenses can generally be changed out when needed.

A bullet camera allows a security expert to purchase one product that can be used for almost any purpose that arises. It is truly the jack-of-all-trades in the security camera world. Because of this, bullet cameras are often the most economical solution to evolving security needs.
