Before Purchasing A Home Security System By Victor Epand There are some really basic things that you may need to know before you decide to purchase a home security
system, whether you plan to self install home security or have a professional
install it for you. Homeowners are often overwhelmed with the amount
of products available for purchase when trying to select a security
camera system for their homes.
Often times, you will want to ask some basic questions that usually narrow the
product selection quite a bit. The first thing you will want to know is if the
system will include cameras for indoor, outdoor, or both. In most cases both
is the answer. Low light conditions outdoor require the use of infrared or very
low light capable cameras. Even some high resolution name brand cameras can fail
to provide coverage in no light or extreme low light conditions. can you self
install the home security system yourself is another question you might ask?
Special infrared cameras are often referred to as night vision cameras and can be used to ensure proper coverage in these situations without much added expense depending on distances being covered. Homeowners should be advised to cover all sides of their home and to take into consideration that wide angle cameras with night vision vary in the range the infrared covers. The longer range cameras can be costly, but they can also deliver a better quality image as these long range infrared cameras are usually higher resolution as well.
If the areas have adequate lighting so that one can walk around well during a dark evening, then color cameras can be used. Choices are then more about esthetic's and include styles in dome, bullet, or fixed cameras in more intimidating housings. Next,
you should ask how many cameras are needed, and remember that areas requiring closeup coverage will demand a single and separate camera. One camera can not show closeup detail and also show wide angle view.
The police with get many calls after vandalism occurs to mailboxes, cars in the driveway, and pets being mistreated by neighbors. Whatever the area needing coverage, certain areas may need special coverage requiring a telephoto lens depending on distance. Homes with long narrow driveways or those requiring perimeter coverage will require security cameras with vari-focal lenses. Distances of fifty five feet or greater would benefit from bullet or professional cameras with 5-50mm or 9-22mm vari-focal lenses. These lenses can be adjusted to widen or narrow the field of view to the proper focal point in question. In this case many bases are covered and if the focal point should ever change an adjustment will be easy enough.
Special infrared cameras can be used to illuminate areas several hundreds of
feet in distance if these areas have no light. Select manufacturers deal with
this type of camera. Careful observation of the home and lot should be taken
into consideration. Distances can be noted for these certain areas so they can
be matched to security camera specification sheets when shopping. Also, discussions
with trained professional can alleviate any anxiety about a purchase. Usually,
many styles of cameras are available from bullet cameras, dome cameras to very
elaborate pan,tilt and zoom cameras. Self install home security systems may be
cheaper, however discuss this with a professional first taking into account the
issues mentioned in this article.
