IP surveillance camera system is a network operated camera system. Through the help of intuitive apps in your smart phone, you can rapidly and easily view your camera feed from anywhere and anyplace through a Wi-Fi, 3G or 4G connection.
It is an effective security camera system which will send an alert whenever someone enters our home in our absence and captures the images of each and every moment when we are away. The IP surveillance system is a system that fits all such requirements in the most effective manner. There exist a wide range of IP surveillance cameras which we can buy from the market and stay protected.
Attributes of IP surveillance camera system:
a) This camera system provides two-way audio via a single network cable that enables users in order to communicate along with what they are observing over the camera.
b) It offers flexibility in a way that it can be moved around anywhere over an IP network.
c) Protection of data via Encryption and authentication: IP cameras provide secure data transmission with the help of encryption and authentication methods like WPA, WEP, WPA2, TKIP and AES.
d) Provide Remote accessibility: We can view live video from the selected cameras from any computer, anywhere, and also from several mobile smart phones and other devices.
e) Modern IP cameras possess ability to operate without an additional power supply. They can operate with the PoE (Power over Ethernet)-protocol which provides power via Ethernet cable.
IP surveillance and CCTV camera:
Initially the video surveillance employed analog technology only like CCTV or closed circuit television. It records the video on video tapes; however it was unable to send the live information in real time. Thus, it was not as useful method of the video surveillance whenever you require practical information within a moment. For instance, if you are monitoring the storefront remotely, you require information on an ongoing basis instead of simply after the event. Additionally, CCTV technology need manual transfer and changing of the tapes regularly and did not offer good picture quality.
Video surveillance, on the other hand provides powerful, effective, and affordable security protection for both the residential and the commercial areas. Technological innovations and techniques have made the video surveillance options easy to operate, scalable, and customizable tailored specifically for your purpose.
Difference between analog cameras and IP cameras:
Analog and IP cameras differ in the way in which video signal is transmitted. Analog cameras transform the signal into a format which can be received by the TV, a VCR, a Matrix System or a monitor. Several modern analog systems utilize a DVR as a recording medium, transforming the analog images into digital format.
On the other hand, an IP camera digitizes video signal from the beginning utilizing a specialized encoder which consists of an onboard web server. Images remain digital without any necessary image conversions and image degradation because of distance travelled over the network. High-end IP cameras, like the Spectra HD by Pelco, provide a 2.0 Megapixel resolution, delivering unmatched forensic detail. The resolution offered by this camera is serves as an indispensable tool for the commercial and industrial places where security measures requires high precision images which will make it easy to recognize the faces, license plates and so on. Also, an IP camera is a network device where a captured video can be viewed not only through the existing network, however also through a web browser which can be accessed through the Internet.
Working of Internet camera or IP surveillance camera system:
The camera system whenever captures an image and in case user sitting at the remote location wants to see the image or video, (the procedure of capturing image is same as that of normal one) compress the files and transmit them over the network to the person wanting the file. It is connected directly to the network similar to any other device like a printer or scanner.
It can use mainly three types of network for security applications:
a) Wired networks: It will connect to the broadband modem or the router through Ethernet cables (RJ45, CAT5, and CAT6). These are the fastest and most secure way in order to connect, eliminating the chance of signal interception and interference.
b) Wireless networks: Such networks use a WiFi router in order to transmit the data to and from the wired modem. They send the data at a slower rate in comparison to the wired network, and they have increased vulnerability to the unauthorized access, though this can easily be mitigated through the use of encryption. This reduced security can be balanced through the ease of setup and customization of the wireless network.
c) Cellular network: This network tends to be slowest among the three, however it is more secure in comparison to the WiFi. In case, cameras are equipped with the cellular transmitters, they do not even need a LAN to be in place, so virtually no installation required in such case. These kinds of cameras, though, can be quite expensive, especially while transmitting the high quality video.
