For many homeowners who look for home security options, wireless outdoor security cameras provide an affordable alternative to installing hard-wired security systems. There are many advantages to using a wireless camera system. For instance, wireless cameras have fewer cables and are much easier to install than their wired counterparts. Additionally, wireless cameras tend to be weatherproof up to -20 degrees Fahrenheit, and can typically last up to five years without losing image quality.
Wireless cameras work on a set number of channels. Each channel connects to a transmitter and then sends the signal out to a receiver. The basic types of wireless outdoor security cameras include: single-channel system; channel mixer; two-channel system; and multi-channel system. Each of these systems allows you to monitor your property from various locations with an easy-to-read, clearly visible Live Feed feature.
Most home security systems today use infrared (RI) transmitters to transfer the signal. This transfer process is very slow (two or three times slower than radio waves), so it’s important to place the transmitter as close as possible to the receiver Camera Wifi ngoai troi. Wi-Fi cameras use a new technology called iocks. This technology transmits at much faster speeds (up to 5 times faster than radio waves), which enables wi-fi cameras to send the signal to a wider area. With this advantage, you’ll have a much easier time finding and monitoring your home and property.
Battery-powered wireless security cameras require a regular power source and can only transmit as far as about thirty feet. They tend to run out of juice quickly, and have a shorter range than their wireless counterparts. Additionally, they’re less reliable. While some models may work for a few days, most batteries will need to be replaced in just one to two months. Replacing the battery won’t take long, but you’ll need to do so at least once a year.
Vision-based cameras send a visual image by using a laser or infra red light and/or heat. This technology provides much better quality video surveillance, has a considerably longer range (than non-motion detection cameras), and does not require the user’s physical accessibility. The most popular camera types using this technology include: front-mounted surveillance cameras, dome cameras, bullet cameras, and bullet cameras with day / night visions. This type of camera also allows users to “see” through obstructions such as trees and other objects.
If you’d prefer not to use your PC for video storage, a DIY (Do It Yourself) option would be your best bet. In this case, you’ll need to purchase a high quality camcorder and corresponding video recorder. These devices have the necessary components to capture (and then store) images without the use of a computer. You should expect at least five years’ worth of HDTV quality images from these devices, though many users upgrade to the latest models available today.
