Making employees safer in parking lots requires a multi-layer security approach. Human security guards are not always paying attention and can’t be everywhere. While having a physical security presence helps, it is better when used with Mobile Surveillance Units (MSU’s). MSU’s have a very ominous look that demands attention with their tall masts and flashing blue strobe lights which is great for deterrence, they also record multiple angles simultaneously. If you only choose one of the above, Mobile Surveillance Units are usually your best bet as they are less expensive and are always watching, recording and providing crucial deterrence.
