Project profile
In a modern restaurant environment, the network is no longer used only for Internet access or customer Wi-Fi. It also provides essential connectivity for internal systems, staff devices, IP surveillance, and other network-connected equipment operating throughout the premises.
For SOL9, SyncTech Solution designed the network, Wi-Fi, and IP surveillance as interconnected parts of the same infrastructure rather than deploying each system independently. TP-Link Omada was selected for the network infrastructure, together with TP-Link VIGI for IP surveillance.
This approach allows the gateway, managed PoE switching, wireless access points, and IP cameras to operate on a structured network architecture. It also provides a foundation that can be managed systematically and expanded as future requirements change.
TP-Link Omada forms the core of the network, integrating the gateway, managed switch, and wireless access points into a centrally managed environment.
A TP-Link ER7406 is used as the network gateway, while the TP-Link OC200 Omada Hardware Controller provides centralized management for the Omada infrastructure.
Centralized management gives administrators visibility across the gateway, switch, access points, and connected clients through a common management interface. This reduces the complexity of managing individual network devices through separate configuration interfaces.
The architecture also provides a more structured approach to future network changes. Additional wireless access points, network devices, or network segments can be introduced while maintaining the same overall management platform.
A TP-Link SG3428MP Managed PoE+ Switch forms the main switching infrastructure and provides connectivity for network devices throughout the project.
Managed PoE is particularly useful in this deployment because both wireless access points and IP cameras can receive network connectivity and power through Ethernet. This reduces the need for separate power adapters at each supported installation point and helps keep the physical infrastructure more organized.
Managed switching also provides support for VLANs, structured port configuration, and network segmentation, creating a more organized infrastructure than placing every connected device on a single flat network.
For an environment combining Wi-Fi and IP surveillance, switch selection should consider more than the number of available ports. PoE power budget, uplink requirements, connected device types, and potential future expansion are also important parts of the overall design.
TP-Link EAP655-Wall AX3000 Wi-Fi 6 Access Points are deployed throughout the indoor areas to provide wireless connectivity according to the restaurant layout and intended service areas.
The wall-plate form factor allows the access points to integrate neatly into the interior environment, while Ethernet downlink ports provide additional wired connectivity where required near the installation point.
Deploying access points across multiple locations allows the wireless infrastructure to be designed around the actual layout and usage areas, rather than relying on a single access point to provide wireless service throughout the entire restaurant.
Wireless configuration and SSIDs can be centrally managed through the Omada Controller, making the Wi-Fi infrastructure part of the managed network rather than a collection of independently configured access points.
A TP-Link EAP625-Outdoor HD Wi-Fi 6 Access Point is used for the outdoor service area where wireless connectivity is required beyond the indoor environment.
Indoor and outdoor areas were considered separately because their installation conditions and service environments differ. Selecting an access point should therefore consider the physical environment, installation location, intended service area, and network requirements rather than wireless speed alone.
This approach allows the wireless infrastructure to use equipment suited to each environment while remaining part of the same centrally managed Omada network.
A restaurant network may contain many different types of devices, including staff equipment, internal systems, wireless clients, network cameras, and customer devices using guest Wi-Fi.
The managed infrastructure therefore supports VLANs and logical network segmentation, allowing different services and device groups to be organized according to their intended use.
For example, staff connectivity, internal systems, guest wireless services, and surveillance devices can be logically separated instead of operating together within a single flat network.
This structured approach also makes it easier to introduce additional systems or network policies later, as new devices can be assigned to an appropriate network segment without redesigning the entire infrastructure.
In addition to the network and Wi-Fi infrastructure, TP-Link VIGI IP surveillance was deployed as part of the overall solution.
A VIGI NVR1008H Network Video Recorder provides centralized video recording for the network cameras installed throughout the project.
Unlike a standalone surveillance installation, IP cameras operate as network-connected devices. Switching capacity, network ports, PoE capacity, cabling, and network architecture therefore become important parts of the surveillance system itself.
Designing the network and surveillance infrastructure together makes it possible to consider these requirements from the beginning, rather than adding additional switching, power, or cabling after the camera system has already been deployed.
Rather than using the same camera model at every location, different camera types and focal lengths were selected according to the viewing requirements and characteristics of each installation area.
For selected outdoor locations, a TP-Link VIGI C340 Full-Color Bullet Network Camera with a 6 mm lens is used where a narrower field of view is appropriate for the intended observation area.
A TP-Link Insight S345 Full-Color Bullet Network Camera with a 4 mm lens is used at another location, providing a different field of view to suit the specific monitoring requirement.
Using different focal lengths according to the installation point is important because camera resolution alone does not determine whether the resulting image will provide the most appropriate view of the target area.
TP-Link VIGI C240I 2.8 mm Dome Network Cameras are used for selected indoor areas. The dome form factor provides an installation style well suited to indoor environments, while the 2.8 mm fixed lens provides a wider field of view for monitoring general areas.
Camera placement was considered together with the intended viewing area rather than simply installing multiple cameras with identical viewing angles. This allows each camera position to serve a specific monitoring purpose.
A TP-Link Insight S245Zi Motorized Varifocal Dome Network Camera is used for a location where greater flexibility in adjusting the field of view is required.
Unlike a fixed-lens camera, a motorized varifocal model allows the viewing angle and focal range to be adjusted more precisely to match the actual installation distance and target area.
This makes it useful for locations where the required composition of the image cannot be determined effectively by selecting a standard fixed lens alone.
One of the key design principles in this project was to avoid treating the network and surveillance system as completely separate infrastructures.
Once surveillance is based on IP cameras, the cameras become part of the network environment. Switch capacity, PoE power, network segmentation, cabling, and uplink design can directly affect how the surveillance infrastructure is deployed.
Planning both systems together allows the switching infrastructure to be sized around the combined requirements of wireless access points, IP cameras, and other network-connected devices.
It also creates a clearer infrastructure for future maintenance because the physical and logical network is planned around the systems that actually depend on it.
With both wireless access points and IP cameras using PoE, switch design should not be based solely on whether enough Ethernet ports are available.
The PoE power budget of the switch must also be considered against the combined requirements of all connected PoE devices. This becomes increasingly important as more access points, cameras, or other powered network devices are added.
Using managed PoE infrastructure also allows data connectivity and power delivery to share the structured Ethernet cabling at supported installation points.
This reduces the number of separate power adapters required around the premises and creates a cleaner infrastructure for both wireless and surveillance devices.
One of the practical lessons from this type of project is that a restaurant network should not be designed simply by deciding how many access points or cameras are required.
The design should begin by identifying which systems need connectivity, which devices require PoE, which areas are indoor or outdoor, and which device groups should be separated from one another at the network level.
The wireless design should also consider the actual layout and intended service areas. Deploying more access points does not automatically create a better wireless network if placement, switching, uplinks, and network configuration are not planned appropriately.
The same principle applies to surveillance. Higher camera resolution alone does not guarantee the most useful image. Camera type, focal length, installation position, viewing angle, and target distance all contribute to the final result.
As the number of network devices increases, managing each device independently can make routine monitoring and configuration more complicated.
Using the Omada Controller allows the gateway, managed switch, wireless access points, and connected clients to be viewed as part of the same managed network environment.
This provides a clearer operational view of the infrastructure and makes it easier to maintain a consistent network configuration when additional Omada devices are introduced in the future.
The infrastructure is built around managed networking, PoE switching, and centralized management, providing a structured foundation for future additions to the restaurant's technology environment.
If additional wireless access points, network cameras, network segments, or other connected systems are required later, they can be incorporated into the existing architecture without changing the overall approach to network management.
Planning this flexibility from the beginning is particularly useful for commercial environments, where technology requirements may continue to change after the initial installation has been completed.
This project demonstrates how network infrastructure can serve as the backbone for multiple digital systems within a modern restaurant environment, rather than functioning only as an Internet and customer Wi-Fi service.
By combining TP-Link Omada gateway and centralized management, managed PoE switching, indoor and outdoor Wi-Fi 6, together with TP-Link VIGI IP surveillance, the network and surveillance systems can operate on a structured infrastructure designed around the actual requirements of the premises.
The result is an infrastructure where networking, wireless connectivity, PoE devices, and IP surveillance are planned as interconnected components, making the overall environment easier to manage and providing a clear foundation for future expansion.
