upgrading some are dear due to up the coax telemetry

Just because something is old it doesn't mean it's not fit for purpose.

If you've got a DM with keyboards and 2060's on BBV alarm boards all over a site your not going to replace it just for the sake of it's age are you!

I am not saying don't upgrade but if something is doing it's job well enough and is maintained in good working order I don't see why it needs ripping out.

Every job is different and at the price point of DM it's probably commercial, so if upgrading is required it would most likely be in stages with careful planning on kit compatibility.

Cheap hik would sort it 

Hik will still not be able to control down the coax domes

Because they won't pay for upgrade of course, but great as is

Most of it is still running trouble free to be honest. They will most definitely upgrade when the time comes.
When it's being used in so many stores and with each store having half a dozen or more units, it usually takes time for people to find an equivalent they're happy to roll out.
