IP systems

Like traditional CCTV systems (analogue), this kind of video surveillance system allows to achieve the objectives of security and management required.
It’s distinguished by the fact that the transmission of sound and image be made via the intranet at the premises of the organization, which in some cases may be an added value and convenience for the end user.
IP cameras, as they are linked directly to an IP network, enable users to view live images and audio from one location or multiple locations through the local network (LAN), Internet or intranet.
With analogue cameras images are carried via coaxial cable without any encryption or authentication, which allows anyone to view images from the camera. In contrast, IP cameras can encrypt files that are sent over the network, thus ensuring that only authorized persons view the images.
The image quality of an IP camera that records the image digitally native is far superior to analogue image scanned. This is not always noticed in viewing "live", however, this quality factor is clear when the recovery of the recorded image.
The images captured by such cameras are carried on the IP network through hubs, switches and routers and stored on a PC with the Management and Video Control (NVR) software.
It’s also a full video system based on network, where no intermediate analogue component is used; an IP video system uses the processing of IP cameras as a way to reduce bandwidth utilization.
A major advantage of this solution is the use of the infrastructure of existing structured network, as well as the possibility of supply via PoE (Power over Ethernet), or power through the cable network, which supports data transmission and feeding; the use of Wireless (WiFi) network devices; the possibility of integrated Pan/Tilt/Zoom, audio, digital inputs and outputs, devices actuation and greater flexibility and integration capability with other systems.

Standard IP Cameras and Megapixel IP cameras

There is a big difference between the standard IP cameras and megapixel IP camera:
The standard IP cameras generally have the same resolution as an analogue camera with the addition of having a video encoder to convert the analogue signal to an IP address.
Megapixel IP cameras are high definition cameras that provide high-resolution images (1.3, 2, 3, 5, 8 or more megapixels), this type of camera provides images in which the resolution contains 30-50 times more detail than an analogue camera, allowing cover larger areas without loss of resolution, see better those details and identify people and objects with higher image resolution - a key element in video surveillance.

Advantages of IP cameras:

  • Do not need a computer for images to be sent to Internet or IP network.
  • No need for software or additional cards for normal operation.
  • They are easy to install and have their own IP address, which automatically connects it to the network via a hub/router.
  • Allow viewing MPEG-4 recording and simultaneous Motion JPEG.
  • Provide, in many of them, a two-way audio communication.
  • Images and audio can be encrypted ensuring the integrity and privacy.
  • Allow access to video and audio through a web browser and an Internet connection.
  • The image quality of an IP camera is far superior to digitalized analogue image.
  • They can use the existing structured cabling network, facilitating their installation and reducing the cost of installation.
