Not all disgruntled staff members will attempt to physically assault former managers or smash corporate property. Some bide their time, wait until after dark and then return to their former place of work. Here, you can save yourself a great deal of trouble with surveillance cameras installation. Opt for HD, highly-visible cameras which send a clear message: This property is being watched 24/7. Want to take deterrence a step further? Consider the use of virtual guard services. Trained security staff monitor your property for potential problems — if they see anything, they use 2-way audio to warn off intruders and notify them that police are on their way. Combined with motion detection lights, thermal cameras, and HD-imaging, it’s possible to convince most ex-employees that causing trouble isn’t worth the risk. For those willing to take the chance, the right security system both records their actions and helps law enforcement build a solid criminal case.
