A wireless video intercom is a more advanced version of the conventional intercom. The intercom, or intercommunication device, is a communications system that is used inside a building. This is a stand-alone device and does not depend on a telephone network in order to work. Intercoms are basically used in order to identify unknown persons who are trying to enter a building, most often equipped with a security lock. In previous years, the intercom purely involved voice communications, however with advancements in technology, not only does it now have video, it has already evolved into a wireless system as well.
What's so Good About a Wireless Video Intercom?
For this type of intercom, installation is a lot more convenient because it does not involve wires, and thus is easier to set up as well. Another good thing about having this wireless device is that it can easily be removed and replaced in a different part of the house any time you want to. You can even bring it with you in case you plan to relocate to a different house. Also, since the device already has video capture functions, it will be easier for you to identify who is speaking on the other line.
Are There Disadvantages to This Communications System?
Like any other wireless device, interference can become a significant disadvantage of this video intercom. Other electronic devices, as well as other wireless devices, can interfere with the wireless signals and may affect the performance of the device. Devices like microwave ovens, baby monitors, scanners, cordless phones, wireless routers and other electronic devices that are on the same frequency can cause interference with the wireless intercom. External interference include transformers, motors or lighting fixtures.
Privacy concerns can also be a possible concern as conversations may be picked up from an unsecured wireless intercoms.
Preventing Interferences or Security Concerns
Since interference is the main disadvantage for this wireless device, efforts have been made to solve or reduce this problem. To reduce interferences from same frequency devices, Canada and the United States have assigned a number of frequency ranges for wireless intercoms, which are 49 MHz, 150 MHz, 494 to 608 MHz and 2.4 GHz. As for reducing external interferences, strategic placement of the device, grounding, as well as shielding methods can be done.
A way to prevent conversations from being listened in to by others is encrypt, or secure the system. Putting a security code will help reduce or eliminate risks from invasion of privacy.
Other Features of the Device
Depending on the device model and the price, video intercoms offer different added features. There are those that offer video portability, a wider transmission range, or a better video quality. Basically, the main advantage of a wireless video intercom is that not only can you view the person/s outside your door, you also get the convenience that wireless devices give.
