Each kind of installation is based on specific requirements that allow to satisfy the relevant needs and functionalities, including a proper mechanical optimization.

Main Technical Specifications

CAMellia Videosurveillance and door Camera






Image sensor

  • High quality image ‘backlight’ sensor, for better sensitivity in low light conditions (about twice that a non-backlight sensor).
  • Resolution of the Image Sensor: 1920 x 1080 (‘full HD’).
  • Pixel pitch: 2.9 x 2.9 micron.
  • Frame rate: 60 frames per second.

Wide choice of Optics to meet the application needs which the camera is destined in its different declinations (for example: internal for ‘Video surveillance’ and ‘Track View’, external for ‘Rear View’ and ‘Door View’).
Depending on the needed application, it is possible to guarantee different angles of view till to 180° (‘Fish eye’) thanks to the availability of special miniaturized optics that can be applied as options.

Images Processor

  • Image processor equipped with hardware and ‘ISP’ (‘Image Signal Processing’) dedicated for the optimization and processing of high-performance images with high quality level and ‘Codec’ hardware ‘H264’ + ‘HEVC’ (‘ H265‘).
  • Based on 32-bit ‘dual core’ ARM A9® processor with Linux Operating System.
  • In detail, the Image Processor has the following characteristics:

Image Format

  • Processable resolutions: up to 1920 x 1080 (‘full HD’).
  • Processable frame rates: up to 60 frames / sec.

Image processing functions

  • Horizontal ‘Mirror’.
  • Vertical ‘Flip’.
  • Rotation in 90° steps (‘landscape’ and ‘portrait’ mode).
  • 2x and 3x electronic zoom
  • ‘On Screen Display’ (‘OSD’) with the possibility to insert date, time and title (option).
  • ‘Motion detention’ with alarm signal programmable via Ethernet port (option).
  • ‘Object detention’ (option).
CAMellia Track View Camera

Image compression and transmission functions

  • ‘H264′ compression.
  • ‘H265’ compression.
  • ‘RTSP’ protocol for ‘streaming’ of the images.

Possibility to generate up to three ‘streaming’ streams simultaneously with different resolution configurations, ‘frame rate’, codec and compression factor.


The “Multimedia RECORDER” is a family of high performances and high capacity network Video and Audio Recorders designed for high quality and high frame rate image recording for surveillance inside of trains, trams, metro and any rails vehicles.

The “Multimedia RECORDER” family

Multimedia RECORDER

is based on rugged, State of the art, Solid State Disk Storage (SSDS) technology.

The modular construction and the wide availability of SSDS capacities and technologies, allow to tailor-made the product at exactly the application requirements.

Solid State Disk Storage (‘SSDS’)
– Depending on the product model, one, two or four ‘Bays’ supporting one, two or four ‘Solid State Disk Cartridge’ (‘SSDC’).are installed
– Each ‘SSDC’ can be independently removed and replaced.
– A ‘SSDC’ supports up to five ‘Solid State Disk Unit’ (‘SSDU’) having a 2.5” form factor.
– A ‘SSDU’ can have a storage capacity of 1 Terabyte or 2 Terabyte. Accounting all possible combinations, the Storage capacity of the “Multimedia RECORDER” family spans from 1 Terabyte to 40 Terabytes with different intermediate sizes.


“Multimedia SERVER”

is a centralized processing and storage Unit, perfect solution for any kind of integrated Passenger information, Passenger entertainment and multimedia experiences systems in a trains, trams, metro and any rail vehicles.

“Multimedia SERVER” combines in one device impressive processing power, huge storage, extremely performing connections and networking resources, low power consumption, high reliability and long life cycle.
Every information, entertainment and high performances and high capacity network.

The “Multimedia SERVER” is based on powerful 64 bits quad core ARM® architecture supported by 4 or, optionally, 8 Gigabytes of ‘DDR4’ main Memory.
A strong support of high speed interfaces, mainly ‘Sata’, Ethernet’ and ‘PCIe’, coupled to the high performance cores and data paths, allows the execution of many different high demanding tasks, including the streaming of multiple high quality video.

The “Multimedia SERVER” family includes a rugged, State of the art, Solid State Disk Storage (SSDS) technology. The modular construction and the wide availability of SSDS capacity and technology, allow to tailor-made the product at the application requirements.

The “Multimedia SERVER” is powered by an internal ‘Universal range’ Power Supply. A special ‘Back-up’ Module, based on a Supercapacitors technology, assures safe and controlled shutdown of the products in every conditions, avoiding the risks of corruption of the stored video or the whole ‘File system’.
