Why our Lighting Controller is better than Mesh Network Systems
Wireless Telematics LCMS vs. Mesh Network Systems Are you retrofitting your high wattage parking lot lights with lower wattage LEDs? Congratulations, those LEDs can save you a ton of energy and money! How are you going to control them? In other words, how are you going to turn your new LEDs on and off? There are three options: Option 1: Keep using your timers or photocells. This is a bad idea. It’s like buying a new Porsche but ordering it with manual roll up windows and bald tires. Why would you spend all that money for state of the art LEDs and then shorten their lifespan with your old timers or photocells? Why would you go to all the trouble and expense of retrofitting your old lights and still have the headaches and hassles that you get with timers and photocells? Option 2: Install a mesh network system with wireless nodes on every fixture and a base station to handle all the scheduling. While this sounds good in theory, in real life it is very expensive, complicated and can be prone to problems. If an electrical contractor or lighting company is trying to convince you to get one of these systems, be sure to do a thorough ROI analysis of the mesh network system separately from the LEDs. This is very important! The LEDs are probably going to cut the energy bill drastically on their own without adding an expensive control system. You should figure out what the savings with LEDs will be first. Then, and only then, should you do the analysis on the energy savings from...
Wi-Fi vs. Cell Modules: There is a Clear Winner!
Wi-Fi is great…until it isn’t. For the last two weeks I have not been a big fan of Wi-Fi. My home Wi-Fi router from the cable company died and I had to replace it. I could have waited three days for their tech to come out and replace it but with several power users (my kids) in my home I knew that if I wanted to keep family harmony I would need to tackle the Wi-Fi beast on my own. Six hours later and several hour-long troubleshooting calls with the cable company and the router maker I was finally able to get the Wi-Fi going in my home. I give it about three weeks before something happens and I hear those dreaded words “Dad, the Wi-Fi is down.” I have also been on two flights recently where the Wi-Fi was down. So instead of watching a movie on this four-hour flight I am writing this post on my unconnected laptop. What is my point? We occasionally get asked at Wireless Telematics if our clients can use their Wi-Fi to connect to our controllers instead of the cell modules we use. The short answer is no. And there are three big reasons for that: First and foremost is Data Security. In the past couple years there have been several huge data breaches that occurred when hackers got into a company’s servers through Wi-Fi. One breach was through an HVAC unit at Target and another was through a lighting control system at Home Depot. With our closed loop cell module system there is no way hackers can access your sensitive...
