With people becoming increasingly security-conscious, wireless surveillance is becoming commonplace in people's work and lives. And the application of wireless surveillance is inseparable from wireless bridges.
Due to their ease of installation, cost savings, convenient power supply, and stable transmission, they are favored by many engineers.
However, many users may not know that wireless bridges have other hidden uses besides bridging. Let's explore them today!
I. Using a Wireless Bridge for Wireless Surveillance
A wireless bridge acts as a network bridge for transmitting surveillance video signals, equivalent to an invisible, suspended network cable. It is suitable for environments where the transmitting and receiving bridges have a clear line of sight, meaning there are no obstacles in between. It can be used for point-to-point bridging over short or long distances. For example, using a high-power wireless bridge + directional antenna at the transmitting end can achieve transmission distances of tens of kilometers or more.
Wireless bridges are widely used in urban and rural wireless network coverage operations, long-distance wireless broadband transmission for companies or homes, and remote wireless network surveillance. They feature long transmission distances, high network speeds, and stability. In environments where laying fiber optic cables is not feasible, wireless bridges provide an easy solution, offering quick, simple, and low-cost installation.
II. Using as an Access Point (AP)
Used to convert a wired network into a wireless signal for use by wireless devices, suitable for short-distance wireless coverage.
For example, using the built-in directional antenna of a wireless bridge for coverage can achieve a range of about 1.5 kilometers, with a horizontal coverage angle of about 30-60 degrees (the closer the distance, the larger the angle). If the receiving end uses a mobile phone or a regular wireless network card, the range is only tens to 200 meters (depending on the power and performance of the wireless network card).
III. Using as a Client
Receives wireless signals and converts them into wired signals for computer internet access. After receiving, it can be directly plugged into a computer's network card for internet access, or connected to a switch or wireless router for multiple computers or mobile phones to access the internet. The general prerequisite to keep in mind is: If you can directly detect the desired wireless signal (such as CMCC or ChinaNET) using your laptop's built-in wireless network card or mobile phone at the intended outdoor location for installing the wireless bridge, and you can see the transmitting base station, then you can install the wireless bridge at the same location, pointing it towards the base station to receive the signal. After receiving the signal, convert the wireless signal to a wired connection and connect it to your computer's wired network card.
IV. Used as a Repeater
Wireless monitoring is frequently used in large-scale outdoor remote monitoring projects, such as in forests, islands, oil fields, and mining areas, where obstructions are common. In cases of obstructions or when the transmission distance is too long for a single transmission, it is recommended to use a repeater mode to relay the signal from the front-end to the monitoring center.
It is important to note that the more times the signal is relayed, the more the wireless signal will attenuate. To ensure sufficient bandwidth during transmission and minimize signal attenuation, it is recommended to use long-range wireless bridges.
Summary
With the increasing awareness of security, the demand for wireless monitoring is constantly growing, leading to more and more applications of wireless bridges in various fields. Choosing a reliable wireless bridge manufacturer is crucial. A good supplier should not only provide products with industrial-grade performance but also have a professional technical team and after-sales team to provide technical support.
