The choice between analog and IP technology when deploying home or Business Security Systems can be a tough one for many people. However, once property owners understand these two concepts, they will have no problem in selecting the system that will adequately cater to their needs.
Which is the better option - Analog vs. IP?
For property owners to decide which system is ideal for protecting their property and valuables, they have to look at the two main distinguishing factors between analog and IP security cameras, namely, signal transmission and video encoding/compression.
Analog cameras capture raw video and send it down Coax/Siamese cabling to the video recording systems. Therefore, there is no encoding, at least at the camera level. Traditionally, the analog video recorders consisted of VCR-like recorders, which stored the video on tapes, without any form of compression. Nowadays, the analog video recording systems being used are digital video recorders (DVRs), which have an inbuilt encoder to convert analog video to digital format before storage.
IP Cameras on the other hand, come with powerful inbuilt video processing capabilities, which enable them to capture video, and immediately convert it into a variety of digital formats. As such, the cameras transmit a digital stream down Cat5 or Cat6 cabling to the network video recorders (NVR), for distribution and storage. IP Cameras are different from the analog cameras since encoding takes place at camera level.
The Benefits of IP Security Cameras
Remote Access: One of the greatest benefits of IP security systems is the ability to access surveillance footage remotely. Users can login into their IP Cameras from their local computer network, or even over the Internet to view video footage in real time. This is possible due to the ability of the IP security cameras to encode the captured video at camera level, and thus prepares it for transmission, and storage in network drives, or distribution.
High Resolution: Video encoding at the camera level helps to preserve the integrity of the video, even when transmitted over long distances. As a result, users benefit from the high quality video images that do not degrade with time or distance.
