Portable Audio and Video Electronics
Wifi cameras can range from video chatting devices to security cameras. Here’s everything you need to know about wifi cameras and portable audio devices.
Portable Audio Devices: What are they?
Portable audio devices are a class of technology and electronics that include , but are not limited to, MP3 players (iPods), cassette recorders, boom boxes, and radios. They may be designed to operate on batteries or AC power from the wall. Portable audio devices may also be capable of receiving terrestrial AM/FM radio stations.
Portable Audio Devices: What’s inside?
Some portable audio devices have an audio amplifier integrated into a single, small case. Other portable audio devices consist of separate components housed in their own discrete boxes: the amplifier, the speaker and/or microphone(s), and the cartridge or cassette housing (for tape-based players).
The advantage of including all these elements in one self-contained unit is that it is easy and convenient to operate and maintain.
Most, but not all, include such features as volume control, variable speed playback (for tape-based players), bass and treble controls, an external antenna for improved FM reception in some models, preset stations (on tuner-equipped systems), auxiliary input on boomboxes for plugging in a portable audio player, and headphones or other external speakers.
Wifi Cameras and Portable Video Devices
Wifi cameras are becoming more advanced as the months go on in terms of capability, resolution, connectivity and more. Wifi cameras are an excellent addition to any smart home because they can act as a security camera, baby monitor, nanny cam and even provide video chatting capabilities.
Whats the difference between Wifi cameras and portable audio devices?
Wifi cameras are often built on a similar infrastructure that portable audio devices are, but with one key difference: wifi cameras do not play audio. Some wifi cameras may have built in microphones and speakers for audio, however they are not to be used as such.
Wifi cameras typically do not include a tuner or other means of listening to terrestrial radio stations. They may support analog video output via composite connection(s), but rarely will they support the higher quality connections, e.g., VGA, that portable audio devices often support. Some wifi cameras can be used to stream video and/or audio over a local network or the Internet, but this capability is typically not provided via a tuner.
Wifi camera Connectivity: Power
Some Wifi cameras have one of several possible power options depending on their application including: battery operated (either disposable or rechargeable), AC power from the wall, and solar power.
Wifi cameras can be powered by several methods including: Battery (usually either internally- or externally-mounted), AC power from a wall outlet, wiring directly into your home’s power supply system, and for models that communicate wirelessly with nearby PCs via Wi-Fi, a USB cable.
In addition, many wifi cameras that communicate wirelessly with nearby PCs can also be powered by the PC via a USB cable.
Wifi Cameras and Portable Audio Devices: Connectivity
Due to differences in their transmission mediums, wifi camera’s signals are read differently than those of portable audio devices. While both “transmit” and “receive” information, wifi cameras transmit their data via radio waves (either through a wireless network or directly to a computer) whereas portable audio devices use physical moving mechanical parts to transmit their data.
Wifi Cameras: Transmission Frequency
Wifi camera signals are transmitted over the airwaves and like any other radio transmission system, they have a frequency that the signals must operate on.
Wifi cameras are typically limited in range to 32 feet for 802.11g and 150 feet for 802.11n due to FCC regulations restricting manufacturers from building wifi camera with stronger transmission power than this . This means that there is typically an “environmental limitation” to where you can place your wifi cameras.
Wifi Cameras and Portable Audio Devices: How you interact with them
The way that you interact with either one of these devices is also different, but they both follow the same concept. When listening to a song or watching a video on youtube; the device (portable audio device or wifi camera) sends data to the connected device.
Wifi cameras are reliant on connections an AC power outlet or a PC for viewing the camera but in some cases, wifi cameras can be powered by USB from either your PC or wall outlet if you have a model that supports it.
Portable audio devices can be charged and used using any charging cable with (typically) micro-usb connectors. Most portable audio devices require some charging before the first use or if it has been used heavily.
Selecting the right portable video and audio devices for you
Wifi cameras can run on an internal battery for a specified amount of time (varies between wifi camera models) and typically take around 15 to 60 minutes to fully charge . The average lifespan of these batteries is from 10 hours (for the least expensive ones) to around 6 months (four times as long) for high-end models.
Wifi cameras are generally used for some kind of remote video monitoring application, since wifi cameras don’t typically include an audio pickup or other means of listening to terrestrial radio stations or other sources of audio.
If you need more options on these devices, there are a ton of them on the market. We’ve provided some helpful link to wifi camera’s we recommend in down below!
