It’s covid lockdown currently, October 2021. But somew of the thing we do is classified as an essential service.
CCTV for a local freezing works is definitely essential.

We were contracted by another communications company in Hamilton, to help them with a contract they had with Greenlea Premiere Meats.
The meat works freezer (which can be as cold as -40c) operates entirely by remote console, and CCTV cameras.

We helped another company remove ageing analogue cameras, and replace with IP cameras.
This require some specialist supplies.
The cable we used is rated to operate down to -50c, and the cameras are rated to -40c.

When we arrived, the freezers had been turned of for an hour, and the freezer had warmed to -15c 🥶
