Oldest Security Gear

The other day A CCTV prospect asked if we have any security gear which required no power supply.

I proposed the following unplugged security devices;

Hardworking Security Guard


Fiercest Guard Dog


The prospect told me those 2 options are too troublesome and expensive to maintain, he said he want something which required no power supply nor alive.

I proposed to him yet another 2 alternatives.



He bought some IP cameras from us.
