Why said IP Camera is superior to the CCTV Camera
In most cases, when pepole are thinking about installing a new video surveillance system, then they have to decide between an IP Camera System or CCTV Camera System. We can solve your troubles get by this article to provide some information and perspective that will help you in making the right choice.
Firstly, you must know in detail what they are and what is the difference between them.
1. What is an IP video security system?
Cameras on an modern IP security system, which has a built-in web server, a network interface (Ethernet or Wi-Fi) and can be directly connected to a LAN/WAN/Internet network. Most IP cameras offer motion detection, sending of e-mails, modem support, connection of external sensors, etc. To access an IP camera, software (usually comes with an IP camera) must be installed on the PC or users can access an IP camera via a standard browser. An IP camera can be configured to provide access to the video stream for all network users or only for authorized ones.
2. What is an analog video security system?
Cameras on an modern analog CCTV system send their video in the traditional base band format over coax or UTP cabling back to a digital video recorder (DVR). Here, video is digitized and stored on hard drives. Most modern DVRs are a network device, and as such can be accessed remotely from the LAN, or with the proper configuration, from across a WAN or the internet. There are no tapes to change. Video is kept on hard drives, typically on a FIFO basis so there is always a rolling video archive of the past X days. So, despite the fact that video is being transmitted from the cameras in an analog format, live and recorded video is still available over the network.
3. What is the difference between IP cameras and analog cameras?
The main difference between an IP camera and an analog camera is that an IP camera has a built-in encoder, which converts the image sensor signal into a digital stream. An analog camera transfers the image sensor signal directly to the camera’s output.
Afterwards, you should analyze their own advantages.
1. cost-effective
For now, installing analog cameras coupled with DVRs is still the most cost-effective approach for most security applications. However, the cost of IP cameras and components is rapidly declining. Reduced system cost and added functionality due to general-purpose IP networking equipment infrastructure. Additions, one IP megapixel camera covers more area than an analog camera. In this way, making IP systems more and more affordable and desirable.
2. better quality
As we know, there are poor quality components and good quality components no matter which type of system. That being said, IP cameras do offer some technological advances in the areas of video quality and wireless installations. While analog cameras cannot provide resolution above TV standards, the maximum being about 0.4 megapixel. Resolution of IP cameras can be many times higher (currently up to 5 megapixel) and they can capture a clearer image when objects are moving, so your image will be much clearer with an IP camera. In adition, wireless communication over IP networks has fewer problems with interference, and encryption security is built into the technology.
This round, IP Cameras wins again.
3. lighting
IP cameras excel in capturing high definition, megapixel images but have trouble with low lighting conditions. On the contrary, CCTV CCD cameras perform well across a variety of lighting conditions and manage motion well.
To sum up, whether ip camera or analog camera has its own merits. But in generally speaking, an ip camera has more advantages than an cctv camera.
