General surveillance cameras are divided into two main types: commercial and home-use. In large commercial facilities, large, visible surveillance cameras are commercial. Surveillance cameras installed outdoors, on roads, and in trees are also commercial. Home-use surveillance cameras, on the other hand, are generally small. Indoor surveillance cameras are even smaller. Home-use surveillance cameras are equipped with pan-tilt functions and two-way communication. Outdoor surveillance cameras are equipped with powerful infrared night vision and two-way communication is standard, effectively blocking other people's actions.
Why can surveillance cameras transmit audio and receive audio from other users?
Home surveillance cameras have a microphone and speaker integrated into the board, which allows them to transmit audio and video signals to the receiver on the other end. A common feature is that users can take out their smartphone, open the app, and simply press the talk button to talk directly to the elderly, children, and even pets in their family. Voice signals can be sent wherever there is Wi-Fi coverage or a mobile network is available. What is the purpose of a surveillance camera having audio? First, it can interact and communicate with people at the scene. The target can be the elderly or children, or it can even communicate with pets at home. In addition, by transmitting video data via the Internet, it is possible to receive information on the scene in real time. Images can be misunderstood, but audio will not be mistaken. It is also possible to directly intimidate wrongdoers through audio.
Home surveillance cameras generally do not need to be waterproofed, because they are installed indoors and do not need to be exposed to complex weather conditions. Home surveillance cameras are small and can be installed in many places. For example, kitchen shelves, bookshelves, desks, etc. Home surveillance cameras with ornamental shapes are popular with users. The shape is unique, easy to disguise, and can maximize the function of home surveillance cameras. In any environment, small home surveillance cameras can bring unexpected effects. Two-way voice communication is based on Internet transmission, so if you want to receive and talk audio remotely, you need to make sure that the monitoring point is connected to Wi-Fi. If not, remote voice transmission is not possible.
