How does a Security Camera work?

Answer
Security cameras are useful in improving the safety of residential and business buildings. Home security camera systems have gained phenomenal popularity over the years. With spectacularly enhanced digital imagery and moderate working costs, the use of security cameras has become quite widespread. The use of security camera systems is no longer limited to banks or department stores but is increasingly being used for residential security also.

Home security camera systems let you keep track of children at play and simultaneously can keep an eye on the front door. They vary in their appropriateness and operation, and it is imperative that the proper selection is made based on individual requirements to ensure their effectiveness.

While choosing a home security camera system you must decide on the area to be observed, and the camera should be located at a suitable distance in order to focus on the preferred area. In case there is a need to mount the camera on a wall or structure, a mounting bracket can be placed at the predetermined spot, and the position of mounting screws can be indicated.

While opting for a wired system, the camera and monitor should be connected in accordance with instructions. Care should be taken to not expose the wiring, so the home security system cannot be sabotaged. And always remember to keep these gadgets out of reach of children.

Another crucial issue that should also be given adequate importance is the number of cameras that one would like to employ in the home security camera system. Some systems have room for only one or two, whereas other systems offer more. There are also camera systems which incorporate microphones, allowing you to hear and see the required object at the same time.

would like info on the best and affordable wireless security camera systems. Need at least 4-5 cameras. Need wireless, outdoor use, night vision, and zoom features for plate and face identification. a large area needs to be covered (about 3 acres). However, I mainly need to survelence for parking entrance/exit, Cash register, and 2 locations of shipping and receiving. need to know how to relay feed to central computer which in some cases is over 1200 feet away from the camera feed. thanks!


Answer
It sounds like you have fairly specific needs. If you are looking for licence plate recognition, night vision and zoom features it is not going to be cheap and you should probably stay away from wireless solutions - particularly inexpensive ones.
As for connection to a central computer, this is typically done with a DVR (Digital video recorder) Through IP. Although there are some IP specific camera's out there. Be careful on the equipment you choose as there is some pretty crappy offshore equipment out there. What looks good on a monitor locally may not look so good once the image is compressed and sent over the internet or LAN.

When you look at a system it is best to look at it as a whole. There is a term we use in the industry - crap in crap out. You may have the best the best camera but it doesn't matter one biut if your recorder is crap. Same goes for the recorder, if you have a great recorder and really bad spystore camera's you might as well be looking at a black and white TV in the middle of the bush with no cable.

I don't know what area you are in, but there is some basic info on my website at www.keepsafesystems.ca you may want to contact a professional in your area.

ExtremeCCTV just came out with a licence plate night camera. It is quite impressive but by no means a Costco / home depot unit.
