SYNAPS PoE

To provide services to the inhabitants of a modern city, but also to improve its operation, cities have more and more connected objects to collect data or transmit information. Most of the objects we use in our daily lives are now connected to the internet or will be connected tomorrow to improve the efficiency of the city. The specifications of these objects are still very varied, and in most cases require interfaces to adapt their supply voltage, to change the communication media, to concentrate the signals of several sensors...
This is the role of SYNAPS, a range of products for interfacing connected objects in the city.

But SYNAPS boxes also offer protection of the connected objects. Whether it is natural aggressions, such as lightning strikes, accidental, such as disturbances generated by other equipment, or criminal, such as vandalism for example, SYNAPS provides protection and the guarantee of faultless operation of the connected objects. SYNAPS even has a first-level maintenance function: if an object crashes, it restarts it automatically. And in the event of failure, it alerts supervision.

Supervision of the system and the connected peripherals is done via a cyber-protected webserver.

Companies like to trust video surveillance systems to keep watch on their premises and their parking

lots. They can react quicker if danger threatens and can already deter potential criminals in advance.

In the following example, we look at the video surveillance system for an outdoor company parking lot (area: 150m x 50m). The security of employees was the prime consideration of the owners as they decided to provide camera surveillance for the newly built area, and also to prevent vandalism and theft. On the site, there was one solitary pole suitable to mount the camera on, but it was 200 meters from the main building and there was no data cable between the two. Digging a trench to lay one was not an option for the customer. But an uninterruptible power supply for the video surveillance camera and secure remote data capture were required.

Sebastian Ratajczak from the system suppliers Primary Connection in Wolfsburg (Germany) was entrusted with the concept and implementation of the system. He chose the outdoor SYNAPS PoE network interface box from Slat for the failure-free supply of the M16 day-night camera from Mobotix and the WLAN bridge (Ubiquiti Nanostation) that was selected for the wireless data transmission. The advantage of the outdoor box recognized by Ratajczak was that it was an all-in-one unit that was already equipped by the manufacturer, yet still had additional space for customer equipment if a specific individual solution had to be provided.

Complete Solution

The core components, such as the AC/DC converter, over-voltage protection, LiFePO4 battery and the Ethernet switch with two PoE/PoE+ ports, were factory-fitted. The installer used the available space to fit a 24V passive PoE power supply. Now the solution was complete. The camera and WLAN bridge were powered and could be remotely monitored in real time via the secure SYNAPS web server connection to check the system status: whether working on mains or battery power, the current charging level of the battery, remaining autonomous operation time, the operating voltage, internal temperature of the DC UPS, the network status (display of the interfaces and connected devices) or to change parameters via the HTTPS website. A further benefit for Sebastian Ratajczak was the compact and visually attractive design of the box (IP65/IK10, polycarbonate) as well as the easy installation that was assisted by a special set of fitting parts.

It was clear to the experienced installer that he could kill many birds with one stone using this soultion: the WLAN bridge avoided the need to dig an expensive trench and lay cables, and the outdoor network interface box provided him with a complete logistical solution to simply manage the interface configuration, remotely gather and securely transmit the data. 

"A perfect all-in-one solution", said Sebastian Ratajczak, "whose time and money-saving qualities totally convinced me."
