IP Camera vs. CCTV
CCTV (closed circuit television) cameras have been around since past 70 years. They have served plethora of purposes ranging from getting video feed from rocket launches to surveillance equipment in various places. The evolution of CCTV cameras has been remarkable in the past 20 years. They have become one of the indispensible parts of modern day surveillance and security systems.
Present day IP cameras have been derived from the original CCTV cameras which have been modified to serve the purpose of remote location video feed recording and retrieving. There is still much advancement yet to come but looking into the pros and cons of using both these systems will give us a good prospective on these systems on the whole.
IP cameras in its initial stages were being designed to overcome the problem of coaxial cables usage over long distance. But even before this, there have been lot of improvements and innovations in CCTVs themselves as a whole to make storage and maintenance easier.
CCTV cameras used to be connected to a VCR through a coaxial cable and they used to in turn record video footage into records. Maintenance of these records was a tedious task. More tedious was the task of retrieving them and looking into them and searching for a particular part of it. There was room for human errors, for instance if one would fail to press the record button which would trigger the recording or fail to replace the tape after it was full, the whole surveillance system would break down. These were the kind of risks that were to be reduced while using these systems.
The CCTVs in the following years were much advanced and used DVR cards to record data and high capacity hard disks were used instead of tapes and thus storage problem was solved. But maintaining this system required skilled professionals opposed to the previous system which needed only grunt work knowledge. The system got simpler as it evolved, both for using and maintaining.
The IP cameras were developed to overcome all the problems mentioned with the CCTVs and to add features such as image recognition, remote trigger, e-mail, FTP, HTTP access and more importantly the ability to connect to any LAN and getting to access it from any browser from around the world. The portability and features that it provides made it an instant hit and almost all the CCTVs around the world are replaced by IP cameras. They are very cost effective, making them easily available for general mass and they can be used for regular house hold purposes like baby cams to keep a look on babies.
There are a few potential disadvantages for using IP cams which include its vulnerability to hacking attacks when they are using public WAN. This can be hazardous and can be prevented by using private WAN. Apart from this, initial costs are less when web cams are used and cost increases exponentially with increase in the quality and features of the cams used.
