Specialists in the video over IP industry, Antrica have been meeting the video encoding and decoding demands of markets across the world for over 15 years. Our products are renowned for their varied features, including RS232/485/422 2-way serial data communication, motion detection, sensors and alarm I/O.

RS232/485/422 two-way serial data communication enables the operator to send commands to and from the encoder. Serial data can be used for any purpose, but in CCTV, RS485 has become a standard for sending Pan Tilt Zoom camera control signals to the remote PTZ camera.

Protocols have been developed by all the major PTZ camera manufacturers, but the PELCO-D standard is widely considered the industry standard. Antrica encoders support a large majority of these protocols, as well as CLEAR mode where we simply pass serial data without the need to follow any protocol. Serial data can also be used to control other local equipment near the encoder.

The motion detection features in encoders are used to help the VMS recording system or the local edge-recording system. Motion detection starts recording in most cases to avoid wasting recording space on images where nothing is happening. A camera in a car park can be watching stationary cars for hours on end, but the minute a person moving or car moving is detected, the recording process starts.

Sensor Inputs and Alarm Outputs are (as the name suggests) inputs and outputs from an encoder that can be used to trigger a recording (Sensor) or an Alert (Alarm). A door sensor can tell the encoder that a door has been opened and cause the encoder to stream, record or both. Alarm outputs do the opposite, and trigger a bell or other localised alert.

frequently asked questions

The ANT-3xxxx range is fully ONVIF Profile S & G Compliant.


A fully ONVIF encoder will 100% work as ONVIF guarantees compatibility (ANT-3XXXX range). However, if you need a ‘view only’ stream and can live without ONVIF discovery then we have the ANT-2XXX range which can sometimes integrate. We can provide a public IP stream for you to test if you need.

Yes, we do for larger projects. We also offer a remote way of testing the stream’s integration.

The ANT-36100, as it has alarm/serial data controls, as well as PoE, and is a more industrial-type decoder.

Yes. Providing you have anti-static handling procedures in place, these can be used in any applications where it can be ‘housed’.

This is due to the fact we use low bit rates and compression, so we need at least 1-2 frames for encoding. Decoders need buffering to work, so most latency is in the decoder end.

Yes and no. Any decoding and re-encoding potentially reduces the quality, but using sufficiently high bit rates will allow the quality to look as good as the original.

Yes, these are intended to be low-latency wireless links with Video in and Video out.

Some of our decoders don’t have HD-SDI as an output. These converters offer a solution to have an HD-SDI output when required.


Antrica have taken on the challenge of reducing to zero all single use plastic within its packaging of Encoders and Decoders by the end of 2020. We are also striving to provide paperless shipments wherever possible.

Together we can make the world better!
