Hanwha Techwin adds low frame rate cameras to thermal range

Hanwha Techwin Europe, a provider of video surveillance products and solutions, has launched three new additions to its Wisenet T range, the TNO-L3030T, TNO-L4030T and TNO-L4030TR.

These thermal cameras feature a low frame rate of 8fps, which means they fall outside of Regulation (EU) 2021/821 and the Wassenaar Arrangement and are therefore not classed as “military use”, therefore giving them a very quick delivery time. They come with maximum 320×240 (QVGA) and 640×480 (VGA) resolution support and a built-in 13.7/13mm fixed lens.

According to the Hanwha, clear day and night detection are delivered by the thermal cameras along with the ability to visually monitor the temperature of scenes with vivid colour palettes and on-screen displays. Ideal for manufacturing and industrial facilities, air and seaports and mining areas, the devices work in challenging weather such as fog, smoke and rain and different lighting conditions including complete darkness and backlit areas. Images are high contrast to clearly show temperature differences between an object and a background, so that users can detect incidents more easily. This helps to make unseen details visible without additional lighting.

Hanwha says that the Wisenet thermal cameras provide seven different types of colour palettes which offer flexibility to choose the best image for different scenarios. With these features, operators can easily protect a wide variety of environments from safety hazards and intruders. Equipment failure in industrial settings and any extreme temperature incidents can be quickly detected.

The thermal cameras come with edge-based video and audio analytics for extra operational efficiency and situational awareness, Hanwha says. Sound classification based on the frequency of a sound source can alert operators when an abnormal sound is detected such as screaming or possible aggression. Motion detection, appear/disappear, enter/exit and virtual line sends an alert when objects enter and move through a defined space. The cameras can also detect possible tampering and come equipped with shock detection. Loitering detection also detects objects remaining in a space for an unusual time.
