Choosing between IP or Analog Surveillance Camera Systems
Analog surveillance security cameras have turned out to be a common attribute of modern security systems. However, there have been tremendous advancements in the technology from time to time and analog systems are becoming obsolete. Thus, the count of facilities that have switched from analog to IP video surveillance camera systems has increased significantly. There are numerous reasons for this, ranging from technological to budgetary. Let us have a look at some of them:
Remote Access:
If you have installed IP camera systems, then you can login into a protected server remotely with the help of an internet based interface. It is helpful to have a look at the real-time footage on your Macs or PCs, and a number of different mobile devices like the iPad, iPhone, iPad, along with Android-based devices. Programs like TeamViewer also enable for end-user training and remote support.
Resolution:
A normal analog camera equates to approximately 0.4 megapixels, whereas a
standard IP camera has 2 megapixels, which is more than 5 times the analog resolution. With several IP cameras ranging up to 10 megapixels, it is easy to see how the technology can reduce the total number of cameras needed. A usual illustration would be replacing PTZs (pan, tilt, and zoom cameras) on a garage forecourt with a single IP/MP camera.
Analytics:
The remarkable enhancements in hardware have been harmonized with powerful analytics software. VMS (Video Management Systems) can be joined with other software to enable for a plethora of applications like motion detection, people counting, and license plate recognition.
ALossless Playback:
The footage can be reviewed with several zooms on playback, even on unchanging lens cameras, with no poor quality of the image. This alleviates a frequent trouble with analog systems, where elevated levels of compression can repeatedly leave the picture unreadable.
Hybrid:
High-end NVRs let the current CCTV cameras to be integrated into the IP system. This
can considerably decrease the initial costs and enable a phased approach towards the whole IP surveillance solution.
Wireless:
If it is feasible to acquire a line-of- sight between the location of the server and the
camera, it is likely to trim down cabling costs by transmitting the data without any wires.
Power:
IP cameras can be powered by a myriad of ways. If you want to replace the analog
camera with the IP camera then the existing power supply can be used again or Ethernet cables that allow for PoE (Power over Ethernet) can be arranged. In addition to this, if re-wiring would prove extremely costly, then a device that can enable PoE and data over coax cable can be utilized.
Easy Installation:
The majority of IP cameras are wireless. Thus, it becomes easy to install and
becomes less costly by reducing the professional labor required for installing it along with the wiring costs. If wired IP cameras are preferred as an upgrade they can generally make use of existing wires, further decreasing installation hassles.
Thus, it can be said that switching an older analog video surveillance system to a modern IP digital system is cost effective, easy, and eliminates a lot of the drawbacks inherent to the analog systems.
