Many organizations and institutions, private houses and cottages need video monitoring. Such measures contribute to the prevention of penetration of objects, prevent the theft of property and material assets, and also prevent other illegal actions.
In specialized stores a large selection of various video systems and their components is presented.. They differ in size, resolution, appointment, worth, view and other parameters. The main element of video equipment is a surveillance camera. Image quality and other features depend on its technical characteristics..
Types of Camcorders
All modern camcorders are divided into digital and analog. Between themselves, they differ in the way they process data and transmit the received video signal.
AT analog cameras data comes in analog version, then this format is processed by the camera and it turns out digital. So that the video signal is sent to the monitor, it turns back to analog format.
In a digital video system for data transmission, the format is not converted to analog. The transmitted signal can be compressed and encoded, such actions are inherent in IP cameras. Other HD - SDI cameras remain the same., as is without any conversion.
Although analog cameras are considered obsolete, and most consumers prefer digital video formats, nobody is going to refuse them. They have their own merits.:
- low cost;
- excellent image quality;
- the ability to monitor moving and remote objects;
- high resistance to hacker attacks;
- full transmission of information, lossless;
- no delays in video transmission.
The main reason for the rejection of analog options is the inability to create an image in high resolution. Old-style analog cameras had a format just in 0,7 megapixels. Manufacturers have developed modern models, which are capable of transmitting images in three or more megapixels. New models, having high resolution, almost equated to digital and are no different from them. These include:
- HDCVI;
- HP-TVI;
- AHD and others.
In the case of IP-cameras, data transmission occurs in compressed and encoded mode. For this, optical fiber or twisted pair is used.. Digital video cameras do not depend on the location of the DVR and are able to work in remote access from it.
Analog, IP, analog HD cameras – what is the difference and what to choose? Video
