  IP Camera based Security Setup
   
     
  Once you have decided to opt for the IP camera based surveillance system, you can begin specifying the requirements for your video security system.  Before you buy an IP camera, you need to answer some basic questions.  
   
  While Buying an IP Camera:
     
 
  • How large an area do you want to view with each camera?  The distance to and the width of the area you want to view will determine the type of lens you need.  The higher the “mm” (focal length) the smaller the field of view and the more magnification you get.
 
 
  • How much light is available?  Do you want to monitor and record at night?  The amount of light determines how sensitive the camera needs to be.  You may wand to select a low-light camera.  The "Lux" rating tells you how well a camera sees in dim light.
 
 
  • Do you want to use the camera outside?  If the camera needs to be used in a wide variety of lighting conditions, you need an auto-iris lens that adjusts to the light.
 
 
  • Do you have a large area that requires a Pan, Tilt, Zoom (PTZ) camera?  You can select a camera with either digital PTZ or mechanical PTZ.
 
 
  • What frame rate is required?  A high frame rate is required if you want to record a fast moving object.  But if you are using the camera for general surveillance; you may only require 1 or 2 frames/sec.  The higher the frame rate the more storage space you will require.
 
 
  • How much image clarity and detail do you require?  If you want to view a larger area then you need a higher resolution camera.  Higher resolutions provide more clarity and better image quality.  But if you want to monitor a smaller area and do not want to see a detailed view, a camera with lesser resolution might do.  Higher-resolution images also mean larger recorded video and snap files, thus taking up more storage space.
 
 
  • Do you want to monitor manually or need automatic alerts?  f you simply want to view your IP camera from any location, you need either a PC or a mobile device like a PDA (Personal Digital Assistants) or cell phone with an Internet connection.  Surveillance software can automatically start video recording when motion is detected.  Special video software like WebCam Monitor is used to control the video from IP cameras.  It stores the video, sounds alarms when motion is detected, controls PTZ movement, and much more.  Once motion is detected you can be notified by email, sound alarm, or even receive a page.
 
  Taking these factors into consideration, you can choose among the many IP cameras available in market.  Some of the popular manufacturers are Panasonic, Sony, Cannon, Toshiba, and DLink.  
   
  It's important to consider the compression method used by an IP camera.  Compression reduces the size of the video files generated while monitoring.  Since video files contain a huge amount of data, compression is required to reduce the storage and bandwidth requirements.  The commonly used compression techniques are MPEG-4 and MJPEG.  Let us try to quickly understand how these work.  
   
  MJPEG (Motion JPEG)
  IP cameras using this type of compression can capture images at rates of up to a maximum of 30 frames per second.   In MJPEG recording, each frame consists of a complete JPEG image.  This is referred to as Motion JPEG.  By compressing each frame as an individual image, this produces high picture quality, but when compared with MPEG4, the bandwidth required for transmission and the disk space required for storage are both higher.  
   
  MPEG-4
  The Moving Picture Experts Group (MPEG) is the organization that defined the standards for this format.  With MPEG4, only a small fraction of the video frames are sent as a complete image.  For other frames, only information about the difference between this frame and the previous one are actually transmitted, not the complete image.  Frame to frame coding techniques are based on the knowledge that most frames are similar to the ones preceding and succeeding them.  This means that most of these frames can be transmitted as differences between their neighbors, which in turn means that a lot less information has to be transferred.  The result of sending only image changes is both reduced bandwidth usage and storage space.  However MPEG4 has a lower image quality when directly compared to MJPEG.  
   
  If you want your family and friends to watch the live feed, inform them of your IP address and the port (if you have specified one) to which they can connect to.  You may have to Configure Your Camera and PC For Internet Streaming.  
   
  Choosing MJPEG for Video Surveillance
  Most IP cameras currently available in the marketplace are based on MJPEG.  MPEG4 provides better compression so less storage is required but image quality is lower.  MJPEG offers higher image quality.  
     
  In video surveillance applications that require storage of the video, MPEG4 is not as easy to deal with as MJPEG.  To find a particular frame in MPEG requires first finding the reference frame with regard to which the changes in subsequent frames have been transmitted and then moving to the exact time period you would like.  MJPEG is a less complicated compression.  When you retrieve MJPEG video you can go to the exact frame you want very quickly and easily.  
     
  MJPEG (Motion JPEG) is the compression of choice for video surveillance because it has better image quality and shows graceful degradation at bandwidth constraint.  MJPEG guarantees a defined level of picture quality, which is vital in most security applications.  
   
  Using WebCam Monitor with your IP camera:
  Though IP cameras can be accessed from any location using Internet and can provide live coverage of an event, you need surveillance software for advanced features like motion detection and alarms, as well email and other automated notifications.  WebCam Monitor is an uncomplicated and inexpensive application that turns your PC and IP camera into a sophisticated security system.  
     
  Once WebCam Monitor is on guard, you do not have personally monitor activities recorded by the IP camera or start the recording and alarms.  It alerts you periodically or when motion or noise is detected, depending on your choice.  It can start and stop monitoring at any scheduled time.  You can monitor using multiple devices including IP cameras, web cameras and several audio devices.  Remote monitoring options like live video/audio broadcasting, FTP uploading and e-mail notifications with embedded images keep you informed on all motion and noise events.  You can view all event history and recordings from within the application.  WebCam Monitor provides customizable alerts like Video/Audio Recording, Photo Snaps, Sound Alarms, Launch Program, E-mail and SMS Notifications.  
   
  To work with WebCam Monitor once you have installed an IP camera, you need to follow the procedure given below:  
   
 
1. In the File menu, click on Add Camera Wizard.
2. Click Next on the welcome page.  Choose the Select or add a Network IP Camera option.  Click Next.
3. Click on Add new IP camera button.  Give the IP address and other details of the camera you want to use for monitoring.  Click Ok to add the camera.
4. Click Next.  The camera is added.  You can choose to Add another camera, Start Monitoring with Alerts or Configure Alerts.
5. Click Finish to exit the Add Camera Wizard.
6. If you choose the Configure Alerts option, Auto Configuration Wizard opens.
7. Select any of the five commonly used monitoring scenarios listed.  Every scenario comes with presets that automatically configure WebCam Monitor.  You are required to configure some frequently used settings.  You may even configure advanced settings for the scenario if you want.
8. Click Finish to exit the Auto Configuration Wizard.
 
   
  Quick Settings allow you to easily configure WebCam Monitor depending on your surveillance requirements.  
   
   
     
  You can use the Schedule Devices option if want monitoring to start automatically at a specified time, using an IP camera that is already added.  You can schedule one or more device pairs using this option.  Each pair will monitor for 60 seconds and then switch to the next device pair in the list.  
     
  Under the Which Alerts do you want to run? option, you can select the alerts you want and configure them if you haven’t already done it while using the Auto Configuration Wizard as mentioned above.  
     
  Once an IP camera is added and you have configured WebCam Monitor, you can rest assured that an effective security system is in place.  A simple installation and a small investment such as this goes a long way in safeguarding people, places and things that you hold dear to your heart or consider important.
