Workswell SAFETIS Outdoor – thermal camera for fast detection of the risk of flare-up

: Termokamera SAFETIS Outdoor s krytím IP67. Základní prvek protipožárního systému SAFETIS pro včasnou detekci zahoření. Centrální jednotka systému SAFETIS. Umožňuje propojení až 16 termokamer.

Workswell SAFETIS Outdoor is a thermal camera (thermocamera) specially constructed for the fast detection of the risk of flare-up before the occurrence of fire. It is one of the components of the SAFETIS system, and as results from the name, the SAFETIS Outdoor camera is designed for outdoor installations

The high level of IP67 coverage and mechanical strength ensure sufficient resistance of the thermal camera, which also includes within demanding outdoor conditions. The thermal camera is fully radiometric with a resolution of 336 x 256 pixels or 640 x 512 pixels and with an image frequency of 9 Hz, 30 Hz or 60 Hz.

SAFETIS Outdoor as a fully radiometric thermal camera, enables, in addition to the detection of the risk of the occurrence or the presence of the fire, also with high precision to change the surface temperature (the uncertainty of measurement is 2°C ± 2%). Information about the surface temperature is important for the evaluation of the risk of flare-up as temperature trends are the main information used to evaluate the risk of the occurrence of fire. Due to the high-temperature sensitivity, the system can record the minimum changes in the temperature. The system’s intelligence is, according to the setting of the operator and the adaptation of the system, able to prevent most false alarms.

Upon an alarm, the SMARTIS thermal camera informs the master system through one of seven digital outputs (type of open collector). Individual outputs can be assigned to various events, areas and types of alarms.

SAFETIS thermal cameras come with two temperature ranges, i.e. -25 °C to 150 °C, or -40 °C to +550 °C, with an external filter then +50 °C to 1,000 °C or +400 °C to 1,500 °C

Wide range of lens

To be able to adapt the thermal camera for the stated application, the offer includes four lens with fields of vision 90° x 69°, 69° x 56°, 45° x 37° and 32° x 26°. Depending on the lens used, it is possible to monitor, for example, distant objects or, on the contrary, the surface of a nearby object with a wider area (for example, warehouse, surface of a conveyor or weighing pit, etc.).

The size of the recorded area, depending on the distance and the type of lens used, can be verified n the calculator for the field of vision.

SAFETIS system components

The following thermal cameras are included in the SAFETIS system:

In addition, the offer includes a further two special thermal cameras. One of these is SAFETIS Stainless Steel. The protection cover of this camera is designed to provide resistance under external conditions in special fields of industry where there are highly corrosive influences or the occurrence of aluminium is prohibited. This camera is adapted for demanding outdoor use with a high level of coverage.

The second special thermal camera is SAFETIS EX-proof – a specially modified cover enables to install the camera in an environment with the risk of explosion where it is necessary to comply with strict standards. This camera has ATEX certification.

The principle of fast detection of fire by SAFETIS thermal cameras

The principle of the function of the fast detection of fire or the risk of flare-up by SAFETIS thermal cameras is based on the continuous measurement of heating and temperature changes in the recorded scene. Temperature trends are consequently evaluated and using specific algorithms, the potential risk of flare-up is stated while false alarms are eliminated within the necessary extent. The SAFETIS system is able to react much earlier than all other systems that indicate the symptoms of an already originated fire.

Gradual heating

Flames and smoke have not started yet. There is only the risk of gradual warming. Despite the fact that the smoke detectors do not respond, the SAFETIS system records small changes in heating and can react early.

Smoke generation

Smoke detectors respond in this phase, i.e. at the time when the smoke is generated. However, this is a risky phase where the rapid escalation of a destructive fire can occur. The SAFETIS system would have reacted a long time ago to the origination of this event.

Flare-up

In this phase, flames are visible and smoke is generated. Special CCTV cameras and the smoke detectors respond to this. Usually, this is too late and the loss of property or life frequently occurs.

Typical applications of the SAFETIS fire system

Some of the typical applications of the SAFETIS system are used to monitor the following areas:

  • Industrial warehouses
  • Ammunition warehouses
  • Coal warehouses and conveyors
  • Power plants and electric energy distribution systems
  • Agricultural warehouses, food warehouses
  • ATEX environment
  • Depots and incineration plants, warehouses for hazardous waste
  • Conveyor belts
  • Chemical and industrial plants
  • Cement plants
  • Monitoring of perimeters

Central unit or Web-server

Each SAFETIS thermal camera can be communicated with through a built-in Web-server. This server provides a basic image stream as well as options for advanced configuration and setting all necessary parameters.

The multi-camera system can be connected through the SAFETIS Control Unit. This unit enables to interconnect up to 16 SAFETIS thermal cameras with any construction. Cameras can be configured from this central unit, as well as to show alarms, etc. More information about the central unit can be found on the separate product page SAFETIS Control Unit.
