This is the descendant of the basic uni-directional system used by basic and usually old monitors. These new types of baby monitors however have been integrated with new technology. Instead of just being able to hear your baby, you can now actually talk back to him or her. There are even some devices that will let you send commands to the baby s device to play different music to hush him or her back to sleep. However, for many parents who are concerned with the safety of their child, switching to modern technology can certainly be frightening. But as long as one knows how to set certain prevention methods such as placing the monitor at a safe distance from the baby (at least one meter) and not adding a lot of other appliances inside the baby s room such as televisions or computers, then much harm on the child s health can greatly be prevented. Because of these occurrences, a lot of people have made it a point not to mention any private or confidential information while the baby monitor is switched on. Interference with cordless phones and wireless routers is also a common problem. Every now and then, your baby monitor may compete with these wireless devices for better signal reception. To get the best possible reception and transmission from a 2.4GHz baby monitor with video capability, switch off all 2.4GHz devices in your house. After that, you may turn on the baby monitor followed by your wireless router that is if you have one. Last but not least, you may switch on the base unit of your wireless phone. This helpful gadget actually comes with a wide variety of options to choose from. Perhaps you want to purchase baby monitors with two receivers so that you and your other half could both monitor sounds coming from your baby's room. Having more than one receiver makes it possible for both parents to keep a closer eye on their little bundle of joy. Baby video monitors, instead of just using audio, now make use of visuals. Parents can now opt to choose whether they want a camera installed so that they may be able to monitor their baby visually. The camera sends feeds to its partner video monitor used by the parents. Wired or Wireless Baby video monitors can either be wired or wireless.
