Internet Protocol Based Security Camera Systems

Ip Based Security camera Systems are generally used in most home security systems that utilize Video Management Software (VMS). An Internet Protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed-circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term IP camera or netcam is usually applied only to those used for surveillance that can be directly accessed over a network connection.

Internet Protocol (IP) cameras are available in two options: An IP camera is typically either centralized (requiring a central network video recorder (NVR) to handle the recording, video and alarm management) or decentralized (no NVR needed, as camera can record to any local or remote storage media). The first centralized IP camera was Axis Neteye 200, released in 1996 by Axis Communications. Each camera achieves the same function, which is to capture video and send it through a wireless network or Local Area Network (LAN).Both types of IP camera can be configured so that you can view cameras remotely or locally.

Difference between Centralized and Decentralized IP Cameras.

Centralized-versus-Decentralized-IP-Cameras

The difference between the two types of IP cameras is that centralized camera stores media recordings on a Network Video Recorder (NVR) or Digital Video Recorder (DVR).Decentralized IP cameras have a built-in storage feature that allows media to be stored onto digital media storage devices.Several media storage options are available for decentralized cameras, such as flash drives, on-board Secure Digital (SD card) card storage, network attached storage (NAS) or a hard disk drive (HDD).In addition, decentralized cameras tend to be able to store at a higher resolution as they do not have to worry about bandwidth constraints.

Centralized cameras are more appropriate for multi IP camera platforms, whereas decentralized cameras work best in a multi-server environment where there are two or three cameras involved.Decentralized cameras rely on storage devices to maintain media.This can become a problem when the storage device has reached its maximum capacity.Centralized IP Camera owners do not have to worry about this issue as much. Centralized IP cameras are currently used in over 90 percent of home surveillance systems.When it comes to centralized cameras, the more money paid in licensing the more features you will receive. Decentralized cameras do not require VMS and has free upgrades.Centralized camera owners with VMS are charged according to the number of devices that are linked to the system.Both centralized and decentralized cameras can be connected through a wired or wireless network.

Types of IP Cameras

Internet protocol (IP) cameras are webcams used for surveillance. They are digital video cameras that transmit data over a local network or the Internet. IP cameras make it possible to remotely monitor a security system. Each type of IP camera is ideal for specific purposes. For example, dome IP cameras are made for outdoor use, while PTZ IP cameras provide the best viewing angles, and IP cameras equipped with infrared light are meant for nighttime surveillance. Therefore, it is important that shoppers know the different types of network security cameras.

Wired vs. Wireless IP Cameras

wired-wireless

Wired IP cameras are linked to local computer networks or the Internet via Ethernet cables. This allows the cameras to use maximal network bandwidth and ensures a steady and stable connection. Wireless IP cameras are connected to the network by Wi-Fi or Bluetooth. Because they are wireless, these IP cameras can be used to survey a wider area than wired IP cameras, and they are easier to install, but the connection is not as reliable.

Decentralized vs. Centralized IP Cameras

decentralized-centralized

Centralized IP cameras are a network of linked security cameras; however, they are only the eyes of the security system because a central video recorder that all the cameras link to handles video recording. Central storage ensures that the security footage remains safe even if the camera is damaged or stolen. On the other hand, decentralized IP cameras are stand-alone recording devices. Each records the video stream in a local storage medium, such as a hard drive or thumb drive. Decentralized storage ensures that there is very little chance of losing all surveillance and security footage at once.

Fixed vs. PTZ IP Cameras

fixed-ptc

Fixed IP cameras are network cameras placed in fixed positions. Therefore, they have fixed viewing directions and angles. A fixed network camera is, therefore, used to survey the same area of a property without ever panning away. Although they are fixed, these cameras may also be equipped with different lenses to enhance their functions. On the other hand, a PTZ IP camera can pan, tilt, and zoom using either manual or automatic controls. This wide range of motion allows one camera to conduct surveillance from different directions and multiple angles, which makes it ideal for continuously tracking an object of interest and zooming to investigate.

Day and Night IP Cameras

day-night

This type of IP camera is used to provide all-day surveillance. During the day, the camera functions like a regular IP camera and produces full-color images. At night, it employs infrared light to see in the darkness and produces black-and-white images.

Megapixel IP Cameras

mega-pixel

A megapixel IP camera is equipped with a high-resolution lens to produce detailed images. The minimum resolution of a megapixel IP camera is 1280x1024 pixels. This camera requires significantly higher bandwidth and storage capacity than a regular network camera in order to transmit and store its HD images and videos. These cameras come in handy when users regularly need to review surveillance tapes for details.
