Hanwha Techwin introduces Wisenet QVGA Thermal Cameras

Hanwha Techwin has launched three new Wisenet QVGA resolution thermal models to its camera selections.

Wisenet TNO-3010T

Wisenet TNO-3010T

The three new Wisenet QVGA Thermal cameras are:  Wisenet TNO-3010T: 2.7mm fixed lens. 0.3m minimum object distance, Wisenet TNO-3020T: 4.7mm fixed lens. 1m minimum object distance and isenet TNO-3030T: 13.7mm fixed lens. 8m minimum object distance

Thermal cameras have a unique feature of picking up heat signatures of objects and are unaffected by extreme conditions, such as darkness, harsh weather, bright lights, fog and smoke, as opposed to traditional cameras that rely on light to see images.

It can also be a solution for applications where there are concerns about light pollution.

Other key features that the three new models have are:

  • Vandal-resistant.
  • capture images at up to 320 x 240 resolution.
  • Equipped with audio analysis functionality which recognises critical sounds such as gunshots, explosions, screams and broken glass.
  • Temperature change, shock, object/people detection, loitering and camera tampering detection.
  • Built-in Gyro sensors offer accurate image stabilisation which comes into effect when a camera is disturbed by wind or vibrations, resulting in more stable images.

Bi-directional audio, motion detection and handover to PTZ are also offered as standard, as is the ability to store up to 256GB of data via an SD/SDHC/SDXC memory slot to ensure video is automatically recorded in the event of network disruption.

The cameras offer a choice of H.265, H.264 or MJPEG compression, as well as WiseStream II, a complementary compression technology which dynamically controls encoding, balancing quality and compression according to movement in the image. Bandwidth efficiency is improved by up to 99% compared to current H.264 technology when WiseStream II is combined with H.265 compression.

Head of Product & Marketing for Hanwha Techwin Europe, Uri Guterman, said: “There was a time when thermal cameras had to be used sparingly as they were far too expensive to be deployed in large numbers,”

“The introduction of our new keenly priced QVGA models means that the technology can now be utilised for virtually any application, and not just high budget, mission critical projects.”
