Impakt BC200 Bodycam

The ultimate bodycam for court usable video documentation

Empower your team in the field to stay in control and stay focused. The WEROCK Impakt BC200 Bodycam ensures maximum safety. It documents conflict and dangerous situations with irrefutable video and audio evidence. At the same time, it scores points for its ease of use, reliability and robustness.

Great functions in a compact housing

The Impakt BC200 is packed full of functions and impresses with its intuitive operability. With the recording function, you can easily record high-quality video documents and offer your emergency services security and protection at the same time.

Impakt BC200 also supports you in sudden conflict situations. It has an integrated pre-recording buffer and stores up to 60 seconds of valuable video and audio material before each recording starts. The entire event is recorded using a highly sensitive sensor with a wide-angle lens and integrated image stabilisation in particularly detailed 2K Ultra HD resolution.

The perfect bodycam for all modern requirements in use. Give your emergency services a reliable tool that documents their work and brings certainty in critical situations.

The integrated rechargeable battery is designed for typical everyday use and records up to 12 hours of video with one battery charge. Thanks to the industry-leading fast charging technology, the bodycam is fully operational again after only 3 hours. During the charging process via the docking station, Impakt BC200 synchronizes the data and then automatically deletes them from the memory.

An integrated memory of up to 64 GB offers space for several days of video recording. This is made possible by the new H.265 HEVC video compression. It offers the same image quality as older standards with considerably lower memory requirements. This allows more flexibility in use and considerable cost advantages in archiving.

Built for tough use

Missions with body cams often do not have optimal working and viewing conditions. Especially for demonstrations a meaningful situation picture is important. Transmit video and audio recordings via WLAN live streaming to the head of operations to be able to react faster and smarter to any situation.

A further highlight is the integrated photo function, which allows the marking of important events during video recording. This allows an officer in a pursuit on foot to mark the location where drugs or weapons thrown away by a suspect can be marked for later recovery, and can be retrieved very quickly during evaluation.

Impakt BC200 scores with its simple operation using
only three control elements and a powerful sensor. Even in complete
darkness, the bodycam delivers clear video material thanks to automatic night vision mode. With a depth of just over 2 cm and a weight of just 120 grams, the Bodycam can be carried without any restrictions. Nevertheless, it is robustly built, water and dust proof and can even be used in icy temperatures down to -20°C.

Data security and de-escalation

Often the use of a body cam helps to calm down difficult encounters. Due to the preventive character of de-escalation, the Impakt BC200 is the ideal tool for deterrence. Although it cannot prevent all incidents, it does contribute to a rapid clarification. The large button with a red LED and camera symbol around it draws the attention of those affected to the recording.

What happened where and when? Impakt BC200 has an integrated GPS module for determining position. A usability is ensured by a traceable identification. All BC200 videos contain a watermark with time stamp, identification of the camera and location.

The secure AES256 encryption of the recorded material ensures that no manipulation can be made and that the data is worthless in case of loss. In addition, the data security is increased by the fact that the bodycam has no playback elements. After successful data transfer at the office, the data is automatically deleted from the device’s memory.

Fields of application

■ Police operations such as road checks, demonstrations, prosecutions

■ Documentation of fire brigade operations

■ Proof in the security service and Personal security

■ Public order offices

Frequently asked questions

Usability of bodycam recordings in court

Recordings from a police officer’s body cam can be used as evidence in court.

The following applies to recordings made by private individuals: The authenticity of the video must be guaranteed, so that e.g. posed situations are not wrongly evaluated. Therefore the origin of the video must be just as comprehensible. One must be able to indicate where the video was created and how, with date, place and time information. Exactly the same must be able to be called also the camera type. Then also such secret recordings can be released by a judge, for example for the investigation work of the police.

As with dash-cams, the recording must not be permanent. According to a judgement of the Federal Court of Justice in Karlsruhe, this is inadmissible with reference to the Data Protection Act. However, this inadmissibility does not mean that the videos may not be used in civil proceedings. It is always a question of weighing up the individual case.

Secretly made recordings

Each of us has the right to his or her own picture, so it must be asked before it is taken. This also applies to pictures that are taken secretly. Basically, it must be said that secret video recordings tend not to be used in court.  On the contrary: If you record a person against their knowledge, you even commit the criminal offence of “violation of the confidentiality of the word” and can be sentenced with a fine, or even imprisonment for up to 3 years!

Videos without sound, on the other hand, could in some cases be used in legal proceedings without consent. The personal right of the person to his or her own image remains unaffected by this, of course. In any case, please inform the person concerned before starting the recording that he or she is being recorded now.

Photos taken by police officers by mistake can also be used in court. This was confirmed by the Düsseldorf Regional Court in February 2019.

Important: Please note that this is not legal advice, but only our assessment of the current legal situation in Germany. Outside of Germany the legal situation may differ. In case of doubt, please ask a lawyer.


Basically everyone is allowed to use and wear a bodycam, but there are some basic things to consider:

Using a Bodycam in your own walls

There are no restrictions for the use of a body cam in your own apartment.

Use of bodycams in non-public places

In non-public places, the use of cameras of any kind can be determined by the owner of the house rights. Thus also the carrying and use of Bodycams can be forbidden. Here the house right stands only once over your interests, if it comes to a goods consideration. The “mere” wearing of a bodycam is usually permitted (unless the holder of the householder’s rights specifies otherwise).

The use of bodycams by authorities in apartments is currently controversial, as this is an invasion of privacy. This is handled differently from state to state.

Use of bodycams in public places

In public places you may wear a body cam at any time. What is not allowed, however, is “permanent filming”.

General restriction on the use of bodcams

Unauthorized and unannounced filming of persons without their consent is not permitted by law. The right to one’s own image (personal rights) is strongly pronounced by the Basic Law in Germany. If you film other persons without their consent, any of the filmed persons can send you a warning and demand a cease and desist declaration. If the warning is carried out by a lawyer, the lawyer must also pay the lawyer’s fees.

If you plan to use body cams regularly in your company, make sure to add this to the house rules and point out the video recordings.

Important: Please note that this is not legal advice, but only our assessment of the current legal situation in Germany. Outside of Germany the legal situation may differ. In case of doubt, please ask a lawyer.

What is encryption in general?

Basic: Encryption is the process of converting a plaintext into a ciphertext. The ciphertext can only be converted back into the plaintext with a matching key. The conversion is finest mathematics and will not be explained further here. The field of research dealing with it is called cryptography.

What does AES256 stand for?

AES stands for “Advanced Encryption Standard” and is the successor of DES (Data Encryption Standard). It is a symmetrical encryption method, i.e. the key for encryption and decryption is identical.

The Rijndael algorithm has variable, independent block and key lengths of 128, 160, 192, 224 or 256 bits. Rijndael offers a very high level of security; it was not until more than ten years after its standardization that the first theoretically interesting, but practically irrelevant attack was found.

AES restricts the block length to 128 bits and the choice of key length to 128, 192 or 256 bits. The designations of AES256 refer to the selected key length of 256 bit. The algorithm is freely available and may be used without license fees and implemented in software and hardware.

How does this encryption work?

The mode of operation is based on a series of byte substitutions, permutations and linear transformations, which are carried out on data blocks of 16 bytes – hence the term block encryption. These operations are repeated several times, and in each of these rounds an individual round key calculated from the key is used in the calculations. If only a single bit in the key or in the data block is changed, a completely different cipher block is created – an advantage over classical stream encryption.

You can find an illustrative video of how encryption works in technical terms here:

Fields of application for AES encryption

AES encryption is not only used in our products but also in numerous other technologies such as WLAN (WPA2), SSH and IPsec.

How secure is the AES256 encryption?

AES256 is classified as secure because there is no known algorithm that could crack it. It is also still secure against the so-called brute-force attacks. Only when the computing power of computers increases massively, one has to think about it. According to the current state of the art, trying out all combinations takes 3.31 * 10^56 years by a supercomputer.

AES256 is approved in the USA for government documents with the highest classification level.



The Impakt BC200 uses a combined encryption of AES256 and RSA2048. The data on the camera is double encrypted (AES256+RSA2048). In case of theft, the perpetrator has no possibility to use the data. Even after the transfer to the own systems the video files remain RSA2048 encrypted and can only be decrypted with the help of the private key.

The Impakt BC200 Bodycam comes with the software package “Impakt Tools” which includes the MapVideo Player.

With this you can play encrypted and unencrypted media. At the same time an online map (provided by the Bing map service) shows the current location and the entire route. So you can always see where the current recording is happening.

The files remain encrypted on the hard disk and only decrypted in the RAM.

The English term “Ultra HD” (abbreviation for Ultra High Definition) means completed and translated “extremely high resolution”. The term “Ultra” was chosen to make clear the higher quality compared to “Full” HD (1920 × 1080 pixels).

Screen resolution or image resolution is a colloquial measure of the image size of a raster graphic. It is indicated by the total number of pixels or the number of columns (width) and rows (height) of a raster graphic.

2K Ultra HD refers to a resolution of 2304 x 1296 pixels (aspect ratio 16:9) and corresponds to a resolution of 2.99K. In contrast to Full HD+ (2160 x 1080) this is a 22% higher resolution. Compared to Full HD (1920 x 1080) even 31%. The resolution has not yet been officially certified by the Consumer Technology Association (CEA) as it is mainly used in industrial camera systems.

Yes, in our opinion the documentation of operations is completely safe for paramedics and firefighters. In fact, some fire brigades already use bodycams for documentation and communication during their operations.

Please note that the regulations can vary from country to country. In Germany, “affected persons” (i.e. people who are filmed) must be asked before they are filmed. As there is no official order, people can refuse to do this. In this case you are not allowed to film the person.

In any case, if you are filming in private homes, you should refrain from publishing the video material. Even if you have permission.

Yes, the battery can be changed. It is important to us that our products are used as long as possible. For safety reasons and because of the waterproofness of the housing there is no comfortable way to change the battery – nevertheless the exchange is possible and can be done at low cost by our service.

Cobalt is a raw material that is important for the production of lithium-ion batteries on the one hand, but is also repeatedly criticised for problematic degradation conditions on the other. These include dangerous mine shafts, lack of basic supplies and the systematic occurrence of child labour.

Cobalt is also built into the battery of the Impakt BC200 Bodycam, as in all smartphones or tablets. Here, the chemical properties of cobalt ensure a high energy density and rapid charging capability. Unfortunately, this cannot be avoided at present. However, we are monitoring the battery market very closely and will work towards conflict-free mining of cobalt.

One Impakt BC200 battery contains approximately 3 grams of cobalt.

Using modern battery recycling processes, over 90% of the materials used in the battery – including cobalt – can be separated and processed. In this way, new batteries can be created from old ones.

Unfortunately it is not possible to make a general statement here. The battery of the Impakt BC200 Bodycam is powerful and designed for industrial use. With 11,4 Wh it is designed for the typical patrol day of 12 hours at the German police. It can withstand hundreds of charging cycles and is designed for use in temperatures ranging from -25° C to over 70° C. While the battery is very resistant in cold weather, its performance drops noticeably at high temperatures above 40° C. However, this is not a weakness of the battery, but of the battery technology itself.

Generally speaking, battery life depends on battery health, battery temperature and the functions used. You can achieve maximum battery life by setting the video resolution to 480P, GPS off, infrared off and video quality to low. One of the biggest power guzzlers are functions like WLAN and GPS. If you can do without these functions, you will enjoy a much longer battery life.

All batteries are tested for performance before shipping. The life of the lithium-ion battery is typically up to 10 years or 500 charge cycles for this type of battery, whichever comes first. This makes the Impakt BC200 Bodycam battery one of the most powerful industrial batteries on the market.

Some speak of the surveillance state, victims who have already been victims of violence affirm the bodycam in police operations.

What distinguishes Bodycams from Dashcams or Actioncams? The mode of operation is the same. The Bodycam as well as the Dashcam and Actioncam record more or less the same events and let them be seen again afterwards. Dashcams are designed for car traffic and record lightning fast movements and dangerous situations. The Actioncam becomes the companion in the context of rapid departures or different extreme sports and serves the afterwards accomplished critical argument of errors or equally as promotion or fan video.

High wide angle but also simple use speak for Bodycams in the context of professional applications.

The new Impakt Bodycams are robust recording devices in the form of a small box, which is securely and firmly attached to the upper body on the uniform. The Impakt Bodycam scores with a wide recording angle of 140°, so the whole scene is captured in the policeman’s field of vision.

Full HD recordings deliver razor-sharp images and a recording quality that makes face recognition of perpetrators no longer a puzzle. The shock-resistant body cam switches the light conditions individually and automatically activates the night vision mode. The switching is completely automatic and requires no interaction with the operator.

Due to their weatherproof characteristics as well as the clear pictures even in heavy rain, Bodycams provide maximum safety for police services and service providers in the security sector.

Bodycams and their influence on suspicious people

The bodycam records the whole event, so that every denial becomes a senseless activity. Experiences in the USA have shown that people generally act more calmly and refrain from violent acts. So they have a deescalating effect here. However, the situation here can vary somewhat from country to country. In some regions in Germany, the potential for aggression towards uniform wearers has even increased for switching on the camera. From our point of view, this is a very short-sighted behavior, since the camera records everything. Especially because of the increasing potential for violence against them, we recommend the use by police officers, public order offices and security services.

The Impakt Bodycam does not limit its wearer in any way. The weight of the camera of well under 200 grams is hardly noticeable on the vest. At the same time it is untiring due to the integrated long-life battery, which allows up to 12 hours of continuous shooting.

Citizens hope for more security through the use of body cams, as long as we can catch and identify criminals faster. As with Dashcams, body cams have been criticized by privacy advocates because they can draw attention to other people. In the criminal area, with terror danger or with sexual assaults it is beyond question that a suspect will not give consent to the investigation of evidence and must approve the recording.  The corresponding regulations are anchored in the state laws of the police. There are restrictions here, especially for recording in private homes.

Pre-Recording is a special function of Bodycams, to save a scene that has already passed in the near past. This article will show you how it works and what advantages Pre-Recording offers.

Pre-Recording can prove useful in missions

Pilot projects in the various federal states investigated whether pre-recording is a useful method of reducing crime. The bodycam is located either on the shoulder or in the chest area of the police officers. Both systems have their advantages and disadvantages here. The shoulder camera is about the size of a webcam and is placed on a platform on the shoulder. It offers the advantage that the camera is directly at eye level. This means that the image is directed directly in front of the officer and in the direct field of view of the person wearing it. Body cameras, on the other hand, score points with their uncomplicated and flexible set-up. As they do not have to be fixed, no adjustment of the uniform is necessary. It can therefore also be worn by changing personnel.

Impakt body cams use the special pre-recording function, which allows a scene to be recorded 60 seconds later and saved at the touch of a button. This function is particularly useful when a situation gets out of control.  No matter if it comes to insults, fisticuffs or a brawl out of control, a recording of the situation can help to create a detailed statement about the course of events. Professional body cams also offer evidence that can be used in court.

This is how it works

The Bodycam records the video material in a continuous loop and stores the last 60 seconds in the buffer memory. The flashing LED ring clearly indicates the pre-recording to those affected.

This is how you can imagine the whole thing: The live recorded video material is temporarily stored in a separate memory. As soon as the camera is in pre-recording mode, the recording is permanent and the last 60 seconds are buffered. When the record button is pressed, the data is transferred from the buffer memory to the permanent memory and the real-time video material is attached.

Advantages of pre-recording in use
  • Subsequent recording of the last minute to restore possible events or actions at the touch of a button
  • The perfect evidence to reconstruct statements
  • Sometimes it is not possible to get to the pre-recording button in case of fights or scuffles, because the police officer has to take action
  • Preventive de-escalation effect, as recording of behaviour promotes more respectful treatment and more rule-compliant behaviour on both sides

High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors of the widely used AVC (H.264 or MPEG-4 Part 10). Compared to AVC, HEVC offers about twice the data compression ratio or significantly improved video quality at the same bit rate for the same video quality. H.264 is widely used in Blu-ray discs, Internet sources such as videos on YouTube and iTunes Store, web software, and HDTV broadcasts over terrestrial, cable, and satellite systems.

H.265 Technology

In most cases HEVC is an extension of the concepts in H.264/MPEG-4 AVC. Both work by comparing different parts of a video image to find areas that are redundant both within a single image and in subsequent images.

These redundant areas are then replaced by a short description instead of the original pixels. The primary changes for HEVC include the expansion of pattern matching and differential coding areas from 16×16 pixels to up to 64×64 pixels, improved variable block size segmentation, improved prediction within the same frame, improved motion vector prediction and merging of motion areas, improved motion compensation filtering, and an additional filtering step called Sample-adaptive offset filtering.

The main focus during the development of HEVC was the optimization of file sizes. The ability of HEVC allows information to be compressed more efficiently. The effective use of these improvements requires much more signal processing capacity to compress the video, but has less impact on the computational effort required for decompression.

Compare H.264 to H.265
  • File size: Compared to H.264, H.265 is more efficient and about 50% faster. This is why we use H.265 technology in the Impakt BC200.
  • Macroblock: H.264 provides support for 16 x 16 pixel macroblocks, which do not work well in higher resolution videos. H.265 provides support for 64 x 64 pixel macroblocks, which have higher coding efficiency at all resolutions.
  • Compression ratio: H.265’s compression ratio is almost twice that of H.264, which speeds up data transfers and saves storage space.
  • Intraframe Prediction: The H.265 intraframe prediction feature is more comprehensive. H.265 can allow 33 directions of motion, while H.264 allows only nine directions of motion.
  • Bandwidth usage: H.265 requires much less bandwidth than H.264 codecs. In fact, H.264 requires an Internet speed of 32 Mbps to transmit 4K video, while HEVC can easily do the same with only 15 Mbps.

For the production, packaging and transport of an Impakt BC200, we make compensation payments corresponding to a CO2 emission of 36 kg. The actual footprint is significantly lower. Since the effort and cost of calculating the exact footprint would not be economical for industrial niche products, we and our partners decided to overcompensate significantly. 

Impakt BC200 is available in different versions. Models that are intended for government use and in larger quantities are shipped from Asia without packaging, but only with protective filling in a cardboard box. This provides a weight and volume advantage of around 40%. Bodycams that are sold in individual pieces are delivered in a stable paper carton. The delivery takes place here on the pollution free rail way – a CO2 saving of approx. 90%. Only for particularly urgent orders and if it is logistically unavoidable, we choose air freight.
