Cameras are a little bit different to other IoT devices. Here’s why.
With CCTV cameras, the output is images. Don’t bother trying to get data from them, it’s expensive and disappointing.
Instead, use images for what they’re good at — transmitting information into the human brain.
Let the IoT device trigger the event, then look at the images.
That’s the root of the issue, now here are some details:
Unlike every other IoT device, high bandwidth requirements mean that cameras don’t use Bluetooth or Zigbee. We even advise customers to avoid WiFi.
This is not a place for MQTT or ZeroMQ. Like with the connection protocols cameras are often sending in the region of 1mb/s streaming video and so the protocols designed for small amounts of intermittent data aren’t appropriate.
It’s easy & cheap enough to take the output of a temperature sensor, polling every minute, and store it for almost infinity. With live streaming video, that would start to get expensive. As the survivor of a cloud CCTV business (Camba.tv) I learnt the hard way that it makes more sense to store your video locally if you can. Now, with 64Gb SD cards on the camera, you can.
I can store year’s worth of air quality readings or voltage measurements without worrying too much about personal privacy infringements. A jpeg containing a face or a number plate is quite a different story.
Sometimes, this: Tide Status: 1.3 just doesn’t cut the mustard quite like this:
