The organization of a high-quality video surveillance system guarantees the safety of the facility and people. According to statistics, 30% of the footage with intruders requires sound, as it conveys their dialogue.
Large enterprises have been using internal video surveillance cameras with sound for a long time, providing themselves and the facility with maximum protection. As you may have guessed, today we will take a look at the features of security cameras with audio and describe them in detail.
The Specifics of Sound Recording in Security Cameras
In fact, there are not so many specific features in such cameras with sound recording. Almost all you need to know are the microphone types. The sound quality is directly related to the characteristics of the micro used in the camcorder. But what cameras record sound? The answer is obvious, those that have a microphone. There are the following types of them:
- Internal. This type of microphone is located inside the housing. Based on the fact that the micro is located in the depth under the protective plastic, the sound can be recorded more blurry, have poor quality. Unfortunately, the microphone will not be able to catch barely audible steps and conversations.
- External. They are located somewhere on the surface of the camera body. These microphones cover even the smallest rustle, which is undoubtedly a plus. It is believed that external microphones record sound much better than internal ones.
The Main Advantages of Cameras with Sound
Before buying a security video camera with sound, you need to make sure that you really need it. It is clear that street cameras that cover a huge area do not need sound, but those that are installed in the office require sound recording. Let’s take a look at the advantages of such a video surveillance system:
Suspicious noises. Cameras do not always manage to record intruders since they are experienced people. They can hide so you will not even see them. In this case, it would be nice to have a microphone on the camera. The presence of extraneous rustles will indicate that a stranger is in the protected room.
Conflict resolution in the department of law enforcement. Household conflicts occur at every enterprise, in small shops, everywhere. It is not always possible to understand who is to blame for a particular situation and who is the victim. This is where video surveillance comes to the rescue. However, just a picture is not enough, because sometimes words have more meaning than actions. The sound will convey the essence of everything that happens, helping to find the attacker.
These are the most common reasons for installing video surveillance systems with sound. In other cases, it will be okay for you to buy ordinary cameras. But keep in mind that any office, in fact, requires cameras with sound.
When choosing any of the CCTV cameras, you must familiarize yourself with the technical characteristics. We do not know which camera you need and for which office area, so here the choice should be made based on your individual needs.
