Questions:
Is your wired system better than wireless?
Yes – much better!
Wireless systems have major drawbacks that just don’t suit commercial environments:
- Radio signals don’t penetrate metal boxes well. Try using your cell phone in your walk-in with the door closed to see what happens!
- Wireless means sensors will need batteries requiring regular replacement .
- Since Wireless signals don’t penetrate metal well, the sensor will likely be plastic.
- Plastic boxes that have to be opened regularly to replace the battery will not be waterproof.
How much Internet data will Coldsure use – is it secure?
We designed the system with strong encryption and all traffic is TLS encrypted. Further, connections are only made outbound so you don’t have to make any changes to your firewall or router. Just plug our box in and it will work.
The actual quantity of data sent is very small – so little that you will probably use more data loading a single web page than the Penguin will send all month!
What happens if Internet at site goes down?
The server will send out an alert to email/phones that Coldsure has lost contact with the site. During the outage as long as your Penguin has power it will store the measurements locally and report them all back to the server when Internet is restored.
