What Is a Body Camera?

A body camera, also called a “body cam,” is a device the size of an adult palm. This device is given to police officers to attach to their uniforms to record their actions in an emergency. The cameras contain lenses and microphones to record any incident that involves an officer. It records video and audio to ensure that all activities are recorded properly in case of an incident. These recordings ensure that neither an officer nor a citizen suffers injustice.

Can You Wear Your Phone as a Body Cam?

No, the answer is a simple no. A body camera is designed to withstand harsh conditions and record videos continuously. A smartphone cannot withstand such conditions for a long time. A smartphone is light build and slim. They are not capable of withstanding the actions that come with the job of law enforcement. Moreover, a smartphone is hackable, while a body camera provides secure storage that is easy to use and tamper-proof.

The most striking feature of the body camera is the ability to record continuously. As long as an officer is on shift, the camera recodes all activities to record everything safely. Unlike a body cam, a smartphone simply runs out of battery before recording a quarter of the shift. 

How Do Police Body Cameras Work?

Police body cams are generally used to record important information and actions. For police, interactions with others are extremely important. The smallest of information can create great change during investigation and problem-solving. For this reason, a police officer must always carry a body camera and activate it in case of something important. Best of all, a camera also acts as a restriction on a police officer. It stops them from using their power unjustly. Here’s how police body cameras typically work:

The body camera is almost the size of an adult palm. Police officers must always carry the camera on the body when on duty. The camera has a lens, microphone, and storage to record and store videos. These components capture video and audio clearly during any interaction. Generally, the camera is not actively recording the video. The user must press a button on the camera to record an interaction. Once pressed, the camera records all video and audio around the user. 

Usually, a police officer must activate their camera in case of traffic stops, arrests, or any encounter with the public. This ensures both the safety and preservation of the information. Some cameras activate automatically in case of sudden accidents or triggers like drawing a gun. 

Once activated, the camera records everything that is happening in the camera’s view. Because these cameras are designed to provide evidence, they usually have better resolution and frame rate. Depending on the camera model, the recorded video is stored in the camera’s or external storage.

After the incident, the recorded video is automatically stored in a specific system of the police station or the cloud storage. These videos are kept safe in storage and can only be accessed by specific personnel so that no one may tamper with any evidence. Moreover, several restrictions and policies ensure that recording cannot be deleted before a specific time. Just think about it. 

Every day, hundreds of police officers record videos. Even if they cover little time, the storage becomes difficult to handle after a certain time. This is why a video is deleted or transferred after a certain time. If not, just the video storage of the police station would consume a large amount of its money.

Of course, in the case of videos that are released to the public, they are modified so that the public cannot see and record sensitive information about a victim or suspect. This sensitive information is removed or blurred so no one may recognize it. 

Body camera footage is valuable because it brings many benefits. Knowing that their behavior is being recorded, police officers also ensure it is within the specific limit. As for the recordings, the public or journalists can request access to them through public records or legal channels.

Whatever a person may say, the police body can ensure that the rights of individuals are always safe. Last but not least, know that the features of the body cams vary depending on the model of the camera or the law enforcement agency.

Do Body Cameras Record All the Time?

The answer is no. Privacy matters a lot for recording. Guidelines and Policies state that a police officer must activate their camera in specific conditions like a traffic stop, public interaction, or other significant incidents. Outside of these, the privacy of police officers and the public is respected by the law. Officers sometimes come across situations where recording is inappropriate; hence, an officer can stop the recording at his discretion. 

How Much Does a Body Camera Cost?

Police body cameras, like other cameras, come in various brands and with different features. Each difference changes the price of the camera greatly. Generally speaking, a body cam ranges from several hundred to over a thousand dollars per unit. The most significant factors that affect the costs are the video quality, battery life, storage capacity, durability, and connectivity options. Of course, other options exist, like the recording and evidence management software. These expenses are essential for maintaining the integrity and accessibility of recorded data.
