The fundamental requirements of video surveillance security system are that it should provide evidential quality images, easy access to recorded data, and a capability to track a target across a specific area. Further security enhancements to a system can also include behaviour recognition systems and the ability to intelligently monitor crowd scenes.
The days of overcrowded clunky keychains encumbering purses and pockets are fading into the abyss. Technology is moving past the necessity of the actual lock and key in many cases. Today, we’re seeing an emergence of key fobs for cars with push-start buttons, and a move towards digital security, mobile credentials, keypads, and biometric access control, such as fingerprint and facial recognition, and even iris detection.
Some people believe installing and maintaining a microphonic fence system can be difficult and time consuming. I find the Defensor System
from Geoquip to be extremely easy to install and even easier to maintain. As long as a few basic precautions are followed, you should be able to get many years of trouble-free operation.

An interesting interview with Vanderbilt CEO Joe Grillo on the acquisition of Siemens Security Products and the vision forward.
It’s always good to perform some basic power calculations before specifying or purchasing a suitable power supply (or power supplies) for your project.
Seems simple enough – Once you’ve decided on the operational voltage, just take the current draw of each device that needs to be powered and add them together.
So you have a number of devices (cameras, locks, detectors, etc) that you need to terminate and power up – you could just connect them all to the same set of terminals on your power supply or (if there were too many cables to fit in the terminals) connect up using a piece of terminal strip and just parallel them all – that would be a bit messy and time consuming, but would probably work.
