Premises Security (part 12) Summary

Premises Security (part 12) Summary

So the sensors are chosen, the cameras are installed. The recording system has been chosen. Power has been assured for an acceptable length of time.
Let's do a final summary:

Part 1 discussed the different types of security systems.
Part 2 explained the differences between Local and Monitored alarms and Perimeter vs. State-change detection along with a look at some different video security surveillance cameras.
Part 3 looked at wireless vs. wired security systems.
Part 4 looked at setting up a video security installation.
Part 5 covered remote monitoring of the video installation and security risks associated with that. It also considered using Motion Detection.
Part 6 Began an overview of NON-video surveillance devices.
It covered;
The “closed loop”, Micro/Magnetic Reed/Thermatic & Pressure Mat switches
Part 7 Continued the overview of NON-video surveillance devices.
It covered detection of environment change rather than physical switch operation
It considered;
Pulsed Infra-red beams, Passive Infra-red (PIR) movement detectors, Proximity detection
Part 8 Completed the overview of NON-video surveillance devices.
We considered that security is more than just Intruder Detection so then looked at Temperature and Light/Darkness security sensors such as;
Thermal Fuses, Thermistor or semiconductor temperature monitors, LDR or Semiconductor light sensors.
Part 9 Considered the two points raised in Part #1 of this series.
The first point was the trade-off of cost & size vs functionality, risk and aesthetics. That led into the discussion in Parts #2 thru #8, of the various types of security system and the devices used.

The second point was the possibility of having the "best of both" in a small easily installed surveillance system AND
extended power coverage by use of a "UPS" as a power backup.
Parts #10 & #11 talked about battery life, working out run-time calculations and the different types of UPS. It also touched on power quality and preferred brands of UPS.

So that wraps up a very high-level view of premises security using digital video surveillance.
I will gladly discuss any specific questions which this series of articles may have either left untouched or perhaps stimulated.

In my next post, I'll start to look at some of the forgotten aspects of security of computer data, caused by corruption, theft or malicious intrusion by virus or hacking.
