How Does a Baby Monitor Work?
- Basics: Since babies sleep a lot and new parents can't stay in the room with a baby the entire time, the baby monitor is a great way to listen for sounds of distress from the child. A baby monitor is a device that sends sound over a one-way radio frequency to a receiver. The distance the sound is projected varies between different models. Most baby monitors are built to work within a distance of about 150 feet. The transmitter is placed in the room with the baby and should be plugged in no more than 10 feet away from the crib. The receiver is usually portable and carried around with the parent throughout the house and outside on the porch or in the yard
- Issues: The radio frequency used to transmit sound from the baby to the caregiver is the same frequency used for cordless telephones and other transmissions that can come from police and emergency signals. More expensive models are built with higher frequency abilities that can eliminate outside interference. Baby monitors used by neighbors also can provide interference in listening to a child in one household. Monitors that come with a scrambler can minimize and remove any outside interference. To work, baby monitors must be turned on at both ends. Less expensive baby monitors that run on batteries may leave parents under a false impression that they are secure in their ability to hear when the baby wakes up
- Advanced: Look for features that allow the baby monitor to work through any number of scenarios. Monitors such as the Evenflo Monitor and Intercom are usually less than $80. They beep when the battery is low and provide an option to turn the sound down and display noise by emitting a flashing light, which may be useful when parents do not want to disturb others in the room. The Evenflo model also features a two-way sending option that allows parents to speak back to the child, sometimes soothing the infant back to sleep. More advanced baby monitors come with video displays that send pictures to the receiver over a digital wireless signal. Audio/video baby monitors such as the Babyview20 by Levana run closer to $200. High-speed microprocessors are built into the latest baby monitors that are placed under the sleeping baby and detect movement. If the baby stops moving for more than 20 seconds, an alarm sounds. Movement detection monitors such as the Babysense V from BabySafe also include the traditional sound monitor and cost about $100
How to Buy a Baby Monitor
Baby monitors are radio transmitters that allow you to hear your baby when you're not present in the room with her. Monitors come in a variety of styles and include many different features, so follow these steps to buy one that suits your needs and lifestyle
- Look for a baby monitor with a small receiver, which will make it more convenient for you to tote around your home. Make certain the baby monitor will run on batteries
- Buy a baby monitor with a light that activates when it picks up sound. This feature will allow you to know your baby is awake and needs you when you're running the dishwasher, listening to music, or vacuuming and cannot hear the noise from your baby's room
- Find a baby monitor that includes two receivers which will allow you to leave first receiver in your bedroom or another room you frequent often, and carry the second receiver around the house with you
- Verify that you can easily clip or attach the baby monitor's receiver to your belt loop if you plan on carrying it around with you
- Search for and buy a baby monitor that includes a low-battery light; when lit, it indicates that you need to replace the batteries
- Research the bandwidth you need for your home. Pricier baby monitors include a bandwidth of 900 megahertz, which provide great reception, but this kind of reception is only available in suburban or rural areas. If you live in an urban area with a lot of interference, a baby monitor with 40 megahertz should suit your needs just fine
- Purchase a multiple-room baby monitor if you have more than several children you need to care for. These baby monitors often come with up to three transmitters and receivers for three different rooms, and can help you keep tabs on all three rooms or a single room

- How is the Frame Rate related to Picture Quality?
Quality can refer to both how detailed the image is and how fast the frame rate is. Frame rate is simply a measure of how many individual pictures make up the video. "Full motion", what you see on television and on VHS tapes, is 30 frames per second, or fps. Most often, security systems record at slower rates, which result in more jerky-looking images but saves tape or hard drive space, allowing longer periods of time to be recorded.
- What is a camera's format?
Camera formats are measured in inches: most surveillance cameras fall between 1/4" and 1". This refers to the usable image size created inside the camera. For most security systems, a small size is fine - 1/4" or 1/3" surveillance cameras dominate CCTV sales. Larger formats do not necessarily result in better images, but can be advantageous in dimly lit situations since they are able to gather more light.
- How do wireless cameras work?
Wireless cameras are basically wireless transmitters carrying a camera picture signal. The camera is wireless and the video signal travels between the camera's transmitter to the receiver. This works much like a radio. The sound you hear on a radio is wireless and you tune to a certain frequency and hear the sound. Wireless cameras also have channels. The receiver needs to tune into the same channel as is being used by the transmitter in order to receive the picture.
The process is the following: The Camera sees the image, and sends it to the transmitter. The transmitter then sends the signal through the air to the receiver, which picks up the signal and outputs it (via a cable connection) to a TV/Monitor/Digital Video Recorder. Keep in mind that both the camera and transmitter require power. The power is provided either by battery and/or transformer/adapter.
In some wireless systems, the camera and transmitter is very small and the power is provided to both from one source. A good example of this is a hidden wireless camera in a clock radio. In this case, the wireless camera is powered by plugging in the clock. The camera and wireless transmitter are provided power by the clock radio internally.
