Guide to Wireless Security Cameras

Wireless security cameras are popular security gadgets primarily for their convenience and hassle-free functions. You can find two basic kinds of this security camera, the analog wireless and the digital wireless camera.

The Analog Wireless Security Camera

This sort makes use of radio frequencies when transmitting signals for audio and video. In open space, the analog wireless camera usually has a transmission range of about 300 feet. However, this transmission range does not always apply because of the presence of interference and obstructions such as for example walls, doors or windows. These obstructions reduce the transmission range to about 150 feet.

A benefit of using this kind of security camera is that it's affordable, as set alongside the other forms of wireless cameras. Also, signals (both audio and video) from this kind of camera can be found by multiple receivers. Depending on the situation, this capability can either be considered a benefit or even a disadvantage DIY home alarm system.

Analog wireless types of cameras are susceptible to interference from other devices, wireless or not. As an example, microwave ovens, cordless phones, routers and computer game consoles are resources of interference for the analog cameras. The signal for this sort of camera isn't secure as more or less anyone in a nearby having a receiver of exactly the same bandwidth can pick it. Another disadvantage of the wireless camera is its average to poor audio and video quality. The grade of the images transmitted is significantly degraded by interference.

The Digital Wireless Security Camera

An electronic wireless camera sends encoded audio and video transmissions over high-bandwidth frequencies (radio). This kind of security camera is a hundred percent secure, as neighbors with radios will not be able to get the signal. Digital wireless cameras have a somewhat wider wireless range as compared to the analog type. The grade of audio and video is also superior for this kind of camera. Another benefit of using this type of camera is that you can link multiple receivers to an individual recording device, like a protection DVR. Because this camera uses digital signals, this camera lets you transmit functions and commands, like switching the lights on or off.

Which is the Better Option?

The greater option is based on the budget and the type of situation that the security camera is going to be used for. For communities or areas that are relatively peaceful or where very little security alerts happen and there are more important necessities than an expensive security camera, then an analog wireless camera would suffice. However, if the location or neighborhood requires more security measures and you are able to afford to invest more on more technologically advanced gadgets, then the digital wireless camera would be the better option. Because wireless security cameras are beneficial equipments, whichever of these two types will be worth the cash that you may spend on it.
