A video encoder / codec is a piece of electronic hardware (electronic circuit) or software that compresses digital video into either an H.264 or H.265 format. It converts uncompressed video to a compressed format which is then sent over a network as an IP stream, where it can be recorded then decoded / uncompressed & viewed elsewhere. An encoder requires an ‘input’ for the video – examples of these include HDMI, HD-SDI , Composite/CVBS, DVI, VGA. 

To put this into context, uncompressed HD video would require a bandwidth of 3,000,000,000 bits per second (3GBits/sec) in a cable or network . Current LAN networks support a MAXIMUM of 1,000,000,000 (1 GBit/s)  bits per second. So, by using compression, an Encoder can take uncompressed video and reduce this to a range of data rates between typically 500,000 and 20,0000,000 (500kbits/sec – 20Mbits/sec) bits per second. These data rates allow compressed video to share network space on existing LAN’s WAN’s with computer and other LAN traffic.

A common example application is when an older CCTV PTZ camera/s needs upgrading or putting onto a newer IP network for remote viewing over a network. Rather than changing the whole system, an encoder can be connected to provide IP connectivity to that camera.

Another application is encoding a PC screen for litigation / recording or monitoring purposes. These IP video streams can then be integrated into a VMS (video management software) where they can be recorded and monitored by other people.

When choosing an encoder, it is important to know the following points as this will help narrow down the choice/type of encoder you require:

  • What input connections to the encoder do you require? (HDMI, HD-SDI , Composite/CVBS, DVI, VGA?)
  • Do you require H.264 or H.265 (This is often determined by your existing network due to the bit rate of the video)?
  • How many different stream types do you need? (Typically 1-4)
  • Do you require a low latency product? (Less than 150ms delay end to end?)
  • What video resolution do you require? (4K, UHD, HD, SD etc)
  • How are you decoding / displaying the video (At the other end)? VMS, Dedicated Decoder?
  • Do you require full ONVIF Profile S & G compliance/compatibility or just VLC player compatibility?
  • What audio support is required? (High quality AAC , 2 way audio etc.)
