It is designed to deliver a consistent and high-speed WiFi signal, minimising lag and ensuring smooth, uninterrupted video streaming. It is also important to consider the ease of installation when selecting a repeater or extender. The Tonton WiFi Range Extender, for instance, features a simple plug-and-play installation, allowing you to improve your security system's coverage in just a few minutes.
When placing your wireless repeater or range extender, ensure it is located in an area with a strong signal, such as near a window or in an open space. Additionally, try to position it away from any metal objects, as these can interfere with the signal. If you are using a directional antenna, make sure it is aimed towards the wireless camera to create a narrow, more focused signal.
Another benefit of using a wireless repeater or range extender is the ability to connect multiple cameras to the same device. This can simplify your setup and reduce the number of components required. For instance, the Ubiquiti wireless access point can accommodate up to four wireless 1080p cameras.
By using a wireless repeater or range extender, you can effectively increase the range and reliability of your wireless surveillance camera system, ensuring smooth video transmission and a stronger signal.

Optimise line-of-sight by limiting obstructions
To improve the range of your wireless surveillance camera, it is important to optimise line-of-sight by limiting obstructions. This means ensuring that there is a clear, unobstructed path between the camera and the receiver.
In wireless communication, line-of-sight refers to the direct path from a transmitter to the receiver, and any obstructions that may fall in that path. A clear line-of-sight is crucial for high-speed communication and can be achieved by strategically positioning the camera and receiver.
The number and density of obstructions between the camera and receiver can impact signal strength and video quality. Obstructions such as walls, doors, and furniture can reduce the transmission range of wireless signals. Certain building materials, such as brick, wood, metal, and concrete, can significantly degrade signal strength, with metal causing a signal reduction of up to 90%.
To optimise line-of-sight, consider the placement of your camera and receiver. Positioning the camera in a location with fewer obstructions can improve signal strength. Additionally, using a high-gain antenna can help focus the signal towards the receiver, reducing the impact of obstructions.
By limiting obstructions and optimising line-of-sight, you can enhance the performance of your wireless surveillance camera system and improve the overall quality of video transmission.

Use a wireless bridge
A wireless bridge can be a great way to improve the range of your wireless surveillance camera system, especially if you are monitoring multiple structures or a large area of land. A wireless bridge is a direct Wi-Fi connection between two antennas – a transmitter and a receiver. It allows you to connect two wireless networks, extending the range of your wireless camera system.
Wireless bridges are commonly used in outdoor projects where it is difficult to run cables between different structures. They are ideal for properties with multiple buildings, such as farms, houses with detached garages, or commercial properties with gated entrances.
To set up a wireless bridge, you will need to connect the transmitter antenna to your IP cameras. Multiple cameras can be connected to one transmitter via a network switch. The transmitter then sends the video signals to the receiver antenna, which is connected to a computer or recorder. This allows you to centrally record video footage from multiple cameras installed across different structures, without the need for physical cabling.
When setting up a wireless bridge, it is important to ensure a clear line of sight between the transmitter and receiver antennas. Obstructions such as trees or buildings can block the signal and reduce the range. Additionally, check that your wireless radios are configured to work in "bridge mode" to ensure a seamless connection.
Wireless bridge systems offer a cost-effective and reliable solution for extending the range of your wireless surveillance camera system. With proper installation and configuration, you can significantly increase the coverage of your cameras, making it a great option for monitoring large or remote areas.

Upgrade your wireless router
Upgrading your wireless router can be a great way to improve the range of your wireless surveillance camera system. Here are some detailed instructions and considerations to help you through the process:
Understand the Limitations of Wireless Surveillance Cameras
Before upgrading your wireless router, it's important to understand some common misconceptions about wireless surveillance cameras. Firstly, wireless cameras are different from wire-free cameras. All professional wireless cameras require a wired power connection, typically through a power adapter plugged into a power socket. Additionally, professional cameras are not the same as cloud-app-based cameras, which exclusively use an app on your smartphone. Professional cameras require a Windows PC or Mac to access their web interface and pair them with your WiFi network.
Assess Your Current WiFi Strength
Before upgrading your wireless router, take the time to assess the current WiFi strength at your desired camera installation spots. This can be done by using your phone as a "signal meter" or by utilising Ethernet cables to connect the camera to your router and accessing its web interface. This step will help you determine if a router upgrade is indeed necessary and if so, what kind of router you should purchase.
Choose the Right Router for Your Needs
When choosing a new wireless router, opt for a powerful router or access point that ensures stable WiFi connectivity to your cameras. Look for routers that support the latest WiFi standards, such as Wireless-N, which offer longer ranges and improved resistance to interference.
