What are IP Security Cameras- How they work
The Internet Protocol Security Camera or IP Security Camera is a type of digital camera that sends image and receives control data through the internet and they are commonly used for surveillance purposes. The first IP security camera was introduced in 1996 by Axis that used an Ethernet network for communication rather than coax cable. The IP security camera provided 4CIF (704 X 480 Pixels) or VGA (640 X 480) resolution.
As of now, more than 100 million cameras (analog and IP cameras) are being used globally. The traditional analog CCTV cameras or Closed Circuit Cameras, on the other hand, refers to analog security cameras that transmit an analog TV signal using coax cable that requires BNC connection to be connected to a Digital Video Recorder or DVR for recording or a monitor for viewing images.
Comparison between IP security camera and analog CCTV – Overview
The IP security cameras dominate the market with IP security camera installation in Dubai becoming a normal phenomenon. The traditional CCTV cameras were primarily used for intrusion-detected applications mostly for alarm assessment purposes.
The following are the benefits or comparisons of IP security camera over its counterpart – the traditional analog CCTV
• Resolution – The resolution of IP security camera is 6 to 20 times higher than analog CCTV camera with the former having resolutions that can range from 1.3 megapixels to 5 megapixels. It results in covering a far wider viewing area than traditional analog CCTV camera.
• Video Quality – The IP cameras for IP security installation in Dubai provides overall higher video quality than analog cameras. Besides, the video is encrypted format and authenticated resulting in the secured transmission of images and videos.
• Ease of installation – The traditional analog CCTV cameras require more cabling than IP security cameras for IP security installation in Dubai. The analog CCTV camera requires a separate cable to control the pan, tilt function whereas for installing IP security cameras it is possible to leverage on the existing cabling infrastructure when migrating to IP cameras by using converters and extenders.
• Costs – The cost of IP security camera even though expensive than analog CCTV camera but the overall cost is less than anticipated due to lower costs for cabling, recording, equipment and labor charges for installation. However, the price of IP security camera is continuing to drop with time.
