Boosting a Medical Institution’s PoE Surveillance System
The Urge for Better Medical Services
The public healthcare system plays a crucial role in metropolitan areas, ensuring that health services are accessible to all. One of the foremost medical centers in Taiwan boasts advanced equipment, cutting-edge technologies, and a highly skilled professional staff responsible for handling emergency situations, major illnesses, and injuries.
As the primary medical facility, the hospital strives to provide patients with the most secure medical environment possible. To achieve this, the hospital recognizes the need for a reliable surveillance system upgrade to monitor patients' conditions and minimize medical disputes.
Elevating Surveillance Capabilities
Despite having analog surveillance systems already in place throughout the hospital buildings, there is a desire to install additional cameras and integrate new surveillance systems within the hospital network. Therefore, Ethernet technology is being implemented due to its scalability and availability.
Power over Ethernet (PoE) technology can be employed in both network cameras and switches. Compliant with IEEE802.3af or IEEE802.3at standards, PoE switches deliver both power and data over CAT.6 cables, providing 15.4 to 30 watts for each PoE camera. The monitoring process will be facilitated by NVR (Network Video Recorder) and VMS (Video Management System) installations, enabling instant data review and real-time video monitoring via LAN or the Internet. A redundant network is essential to prevent data loss and maintain uninterrupted surveillance.
Ensuring Uninterrupted Data Transmission
This hospital consists of three main buildings, each previously equipped with separate analog surveillance systems. To initiate the system migration, it's crucial to establish Ethernet connectivity across the surveillance area. The network devices must work in harmony with the entire surveillance system and create a redundant network topology.
For seamless and stable surveillance results, network redundancy and sufficient bandwidth are indispensable for uninterrupted data transmission. Additionally, technicians prefer easy troubleshooting during maintenance.
Innovative Surveillance Network Solutions
To address these challenges, the client has deployed fiber optic cables among the main buildings to transmit data over long distances. The partnered system integrator has selected EtherWAN's EX17082, EX17162, and EX17242 PoE switches, offering 8, 16, and 24 PoE/PSE ports, respectively. These switches serve as power-sourcing equipment (PSE) to power up the PoE network cameras. NVRs are also connected to the switches for video footage storage. These web-smart switches enable users to remotely reboot devices or turn PoE on/off via a web browser, streamlining camera setups.
In the main server unit, EtherWAN's EX25611 managed Gigabit Ethernet switch is deployed to receive video recordings from the NVRs. This switch features four 1G/10G SFP+ uplink ports, connecting to a Layer 3 core switch and the CMS server.
All the EtherWAN Ethernet switches installed are equipped with fiber optic uplink SFP slots, contributing to network redundancy for potential future upgrades.
Comprehensive Surveillance Network
With over 460 brand-name PoE cameras and NVRs connected to 50 units of EtherWAN PoE switches on-site, all seamlessly compatible with the camera vendor's VMS software, the security personnel can efficiently monitor the entire hospital and review video evidence whenever necessary.
This digital surveillance network significantly enhances the overall safety of the hospital's patients, staff, and assets. Furthermore, the high-resolution video records prove invaluable in resolving medical disputes.
