Video Security Camera Basics for Various Systems
This Article was taken from Spy Geeks written by Dave Norton and is informative to gain understanding of how these systems work
What is a Video Security Camera System?
A Video Security Camera System is an integral component of your home or business’s total security system and has two primary functions. First it is to act as a deterrent to unwanted access or theft of your home or business. Should unwanted access or theft occur, its second primary function is to record the event digitally, and provide as evidence, the series of events that occurred inside the contained perimeter of the video surveillance camera system. A Video Surveillance Camera System is also a tool used to monitor locations where supervision may be needed.
How does a Video Security Camera System work?
The two main components of a Video Security Camera System are the Digital Video Recorder (also known as a DVR) and the security camera. The two are connected via coax or cat-5 cable. When the DVR detects motion in a camera’s field of view it automatically starts recording the image from that particular camera. The image is stored onto a Hard Disk Drive (HDD) similar to the one found in your personal computer. This process of detecting and storing the movement from a camera is sometimes referred to as an Event. If the Event is an unwanted entry it can be easily transferred to a portable disk and given to the proper authorities. The system can also be monitored from an on-site location or remotely via the Internet allowing the user to immediately contact authorities should that be necessary.
Why should I consider purchasing a Video Security System?
While it is true that a Video Security Camera System is most helpful after an unwanted entry has occurred, know that many crimes nowadays are committed by associates of a home or business owner. Having a Video Security Camera System can be crucial in identifying a suspect either through face recognition or by recognizing mannerisms of the suspect, especially if he or she is an associate of the home or business owner. Adding a microphone to the system allows for analysis of the suspect’s voice, providing a tool for quicker identification.
It is also important to remember that your Security Cameras will act as a deterrent to unwanted entry of your home or business. Should a criminal see your Security Cameras and or signs indicating you have a Security Cameras, he or she will probably think twice about burglarizing your place and move on to someplace that won’t be such a hassle.
In some instances you may even get a reduction in your property insurance premiums. Contact your insurance company to see if this is the case in your situation.
Another reason many people choose to purchase a Video Security Camera System is to monitor their children or elderly relatives while away from the home. You can easily setup Security Cameras to monitor hallways, kitchens, and living areas to see if someone has fallen or is in need of assistance, or just to check to see if your kids have gotten home from school
The scenarios listed above are only a small fraction of why people choose to purchase a Video Security Camera System. Only you know the exact reasons why you need a Video Security Camera System. Whatever your reasons are, Spy Geeks can design a custom system to meet the specific needs of your situation at our Orlando Spy Shop.
One of the biggest steps in designing a Video Security Camera System is camera placement. When determining camera placement you should ask yourself the following question: What is the objective of my Video Security System? In other words: What do I want to be able to see? Think back to the reasons why you wanted a Surveillance Camera System to begin with. Our Orlando Spy Store can help you with answering this question.
Outdoor Security Camera Perimeter
Obviously, it would be nice to see everything. Depending on your budget for this project that might be feasible. But what happens when you’re operating on a limited budget? Your objective obviously has to change. Four cameras can be sufficient for your objective but obviously you’re not going to see everything in your yard and in your home. So where should you place your cameras?
Ideally you want to cover all possible entry and exit points to your home or business. Unlike an alarm system, where a sensor is placed at every door and window, each door and window does not need its own separate camera. In most instances you’ll want to place a Security Camera at each corner of the structure, looking down the side of the structure towards another corner. If one side of the structure does not have any doors or windows, there obviously is no point in placing a camera looking down that side.
In an Outdoor Security Camera System setup you can choose to place your Security Cameras either outside the home or inside in a corner window looking out. Know that if you choose to place a camera in a window looking out you will need lighting on the outside if you want to see at night. You cannot use an infrared night vision camera in the window, as the Infrared Light Emitting Diodes or “LEDs” will reflect off the glass and “blind” the camera.
For home applications, once you have found a general area to place the Security Camera make sure that you have access to the home’s attic from that location. Most of the time the wires needed to power the camera and transmit video run through the attic of the home. In an outdoor application, the security camera is most often mounted on the soffit material and the wires are run into the attic to the room containing the Digital Video Recorder. For indoor applications the wires are run through the ceiling into the attic and down the wall of the room containing your DVR.
Many times people want to monitor the inside of their home in addition to or instead of monitoring the outside. Usually their reason is to monitor a child or elderly parent. Placement for this type of situation would typically be in the kitchen, hallways, and common living areas.
Realize that you do not need to place a Security Camera in every room of your house to be protected, unless you just want a camera in a specific location. Living rooms and family rooms are a great place for a video surveillance camera since many times a burglar will have to cross these areas to gain access to other parts of the home.
In a business setting, Security cameras are usually placed in storefronts, lobby and waiting areas, stock rooms, conference rooms, and over the cash registers. Wherever you place your camera it is important to make sure that you have access through your ceiling into the room where your DVR will be placed for your wires to be run. Most commercial office and store space have suspended ceilings so running wires is usually not an issue.
Covert cameras or hidden surveillance cameras can also be used to blend in with the look and feel of your home or business. We sell many types of hidden surveillance cameras at our Orlando Spy Shop. Some of the types of hidden surveillance cameras that we sell include Clock Radios, Wall Clocks and Smoke Detectors.
