Jahnke Thermal II Silencer

The silence in the forest becomes nocturnal

Top devices for night vision

at a fair price!

Jahnke Thermal II Silencer reduces the typical calibration noise of thermal imaging cameras to a minimum. The basic prerequisite for this is the high-quality materials, for example the 35mm lens is made of germanium or the detector is made of vanadium oxide. The HD display with sharp 1,280 x 960 pixels provides a better overview. This means you always have a clear view – even when others have already lost it.

Compare for yourself!

Jahnke Thermal II Silencer with unmatched display

Whether for the quick detection of game or the reliable recognition of vehicles in woods and meadows (range up to 2,400 m) – Jahnke Thermal II Silencer is the ideal companion for your hunting area. And thanks to the large display, it offers you a clear overview of everything that the darkness otherwise does not reveal to the human eye.

The screen built into Jahnke Thermal II Silencer has an extra large 1280 x 960 pixel HD resolution. Compared to devices with much smaller screens (standard here: 960 x 720 pixels), objects can be displayed in much greater detail. And seeing is much more relaxed with such a screen size. Up to a distance of 2,400m, vehicle signatures can be clearly seen with Jahnke Thermal II Silencer.

You don’t need light.
No light at all.

Unlike night vision cameras, which require a minimum amount of illumination (e.g., the moonlight) whose brightness is then amplified, a thermal camera needs no light source.

The magic of a thermal camera lies precisely in this. The fewer interfering light sources, since they are usually heat-signaled, the better the results. Jahnke Thermal II Silencer offers top results with absolute fisternis – on request also in green tone instead of grayscale.

Under these tabs you will find all relevant details about the technology, such as the battery life, the resolution of the integrated HD display and also the water protection class.
We wish you a lot of fun while exploring and of course Waidmann’s Heil while spotting your optimal new thermal night vision device, the Jahnke Thermal II Silencer.


A VOx thermal imaging device (VOx stands for: Vanadium Oxide) uses vanadium as raw material which is rarer and therefore more expensive than silicon, which is used in other thermal devices. VOx is also harder than steel and therefore more difficult to process. Vanadium Oxide has a better thermal conductivity than an ASi thermal device, photons can therefore pass through the image tube faster, resulting in higher performance.

The IP code is defined according to IEC 529, EN 60529, DIN VDE 0470-1 and NF C 20-010 and designates the degree of protection against foreign bodies and contact and water of housings and covers. In the case of protection class IP66, this designates a product that fully protects the electronics or equipment against dust (IP66) and heavy splash water (IP66).

A thermal imaging camera – many possible applications

Have You spotted all six animals?
You are certainly practised in spotting game. You can probably find all the animals in the hunting area without assistance. With a thermal imaging camera like the Jahnke Thermal II Silencer it is more accurate – and faster.

Optional accessories for Jahnke Thermal II Silencer

As an innovation driver, we are constantly optimizing every component of our devices, constantly rethinking them and consistently developing them further.

The additional options Silencer, Softlens and memory expansion can also be retrofitted to your Jahnke Thermal II Silencer. Just contact us.

Silencer function

It is a sound that is hardly noticeable under normal conditions – in the field, however, the clicking of the calibration process of a thermal imaging camera can break through the silence and become a recurring source of disturbance. This is a problem for which we were the first manufacturer to implement an optimal solution: The Silencer function reduces calibration noise to a barely perceptible minimum.

Optionally available for:+ 99,- Euro

Memory expansion

Due to the memory expansion, wildlife observations can be documented even more intensively. Instead of the standard 16 GB, expansion to a maximum of 512 GB is possible.

Optionally available for:

64 GB: + 99,- Euro | 128 GB: + 199,- Euro | 256 GB: + 299,- Euro | 512 GB: + 399,- Euro

Fast charging cable

Extends the life of your battery

As with any rechargeable battery, the capacity of the integrated power storage unit of a thermal imaging camera also decreases over time. To extend the service life and at the same time optimize the charging management, we have a specific fast charging cable manufactured that regulates the charging process and reduces the charging time by up to 30%.


Convenient focus adjustment – At low temperatures – during autumn or winter hunting – handling is simplified because the Softlens function makes focusing noticeably easier.

Optionally available for: + 35,- Euro

Carrying strap

For more comfort: with the optional carrying strap you have the Jahnke Thermal II Silencer at hand at all times.

Optionally available for: + 35,- Euro
