Defense Against Crime


Choosing the correct Security Camera

I received a phone call the other day for a customer looking for a good Nanny Cam or Surveillance camera. She wasn’t really sure what she needed to buy, so I thought I would discuss the different types of camera that are available on the market for those looking to add some type of surveillance in their crime fighting countermeasures. Catching someone doing a criminal act on camera can provide valuable evidence in court or much more.  A video record also provides intelligent data mining and information retrieval if you want to know exactly what happened in any place or situation you want to monitor.

If you have decided in taking responsibility of the safety of your home or business but don’t know what you need to get started , read on.  You need to decide whether to go for the classic CCTV (Closed Circuit TV) based surveillance, web cameras attached to your PC, or the more recent IP (Internet Protocol) camera technology, or even a digital video Recorder.

The CCTV Type

CCTV cameras can produce images or recordings for surveillance purposes, and can be either video cameras, or digital stills cameras. Originally, video surveillance was done using closed circuit television.  This tried-and-true technology uses analog video cameras, coaxial cable and video tape recording devices (VCRs, or DVRs).  These cameras devices transmit a signal to a specific, limited set of monitors.  CCTV systems typically involve a fixed communications link between cameras and monitors, using wires and cables.  This method records what is happening, but does not send you alerts.  CCTV works like a VCR, you have to change cassettes, image quality is average, storage tapes wear out over time, and storage is bulky.  Also, the cameras, monitors, and recorders must be physically close enough together to be connected by cables. This camera type is used by residential, businesses and governments.

The Web Cameras Type

A Web Camera (webcam)  is a video capture device connected to a computer or computer network, often using a USB port or, if connected to a network, Ethernet or Wi-Fi. Web Cams uses the PC to make video available to other viewers. They can be used in conjunction with programs like MS Messenger and Skype to have video conversations with your friends. Images from a web camera can be accessed over the Internet with the help of monitoring software.  Web cam images can be uploaded to a web server, either continuously or at regular intervals. Webcams are currently being used effectively for security purposes.  Webcams can be used to monitor and record activity in small offices, shops and homes.  Monitoring software, such as WebCam Monitor, is needed to complete a video security system.  A web camera works only if it is directly attached to a PC.  You will need a long cable if you want to monitor something that is not near the PC the web cam is attached to.  Web cameras can only be directly read and controlled by one host computer and cannot be shared across a network, but you can view it’s shared images from any internet connected computer. These devices can be found in almost any store which sell computer equipment (Wal-Mart, Best Buy, Staples, E-bay, or even

The IP Camera Type

With the age of the Internet, there have been great strides in video surveillance.  In many cities you can view traffic camera from your home computer.  An IP camera (network camera) is different to a traditional CCTV camera in that the device can transmit data directly over an Ethernet link. IP cameras have an Ethernet port for connecting a network cable, and stream digital video. IP cameras are stand-alone devices that connect to your Ethernet or wireless network. There are two types of IP cameras available – centralized and decentralized.  An IP camera acts like a computer on a network, allowing you to view its video feed from anywhere in your network or over the Internet.  You can monitor multiple cameras at multiple locations from one remote site.  The digital picture quality is superior to analog.  Recordings are highly compressed for easier storage.  Did you ever see the news story of the woman who used her IP camera to catch thieves breaking into her home?

The DVR Spy Camera Type

For all of you would be 007s out there. There is a line of miniature Digital Video Recording devices that can be used to capturing limited video recordings. A DVR Spy Cam is a type of micro DVR which is built into a deceptive package and made to resemble a small object, such as a clock, car remote, pack of cigarettes, sunglasses, or a wrist watch, Known by numerous terms such as cam stick, gum cam, nanny cam, thumb cam, etc., these devices will often function according to their apparent purpose, as in a pen cam that actually writes. Recently, spy cams have increased in popularity due to child care concerns. However, that’s just one possible implementation. The device can be used while your home is being cleaned, for occasional in-home sitter services, for security purposes and a host of other possibilities.  Starting in 2008, spy cams became increasingly popular due to their falling prices and advances in technology allowing for smaller cheaper memory. This meant that the cams could typically record over an hour of video onto built-in memory before needing to offload their recorded content. Many of these devices have a slot/receptacle for a micro SD flash memory card which will expand its recording capacity by several hours. In order to offload the recorded video, it must be connected to a computer’s USB port, at which point it will function as a conventional thumb drive that contains standard video files.

Where do you Start?

When you’re in the market for some security surveillance systems, you may want to ask yourself several questions before you determine what is most suitable for your needs. Do you want to stream over the Internet so you can view your cameras from multiple locations live via the Web? What are you intending to prevent or detect from having a camera system in place? Is a wireless surveillance system a more efficient surveillance system? These are just a few of the many questions you may want to ask yourself. There are several web site or blogs that could answer you questions in more detail

After you have selected the appropriate video surveillance system, take some time to plan and design your system is dedicated to meeting the safety needs of you, your friends, your family members or your business, by assisting anyone who is unwilling to become a victim of crime.  If you want to take personal responsibility arm yourself, or your business with our products and the knowledge of the best way to stay safe in an ever-increasing violent world. In today’s society being equipped mentally and physically is no longer an option.
