In this third part of our multi-part series on setting up your first home security system, we’ll be looking at network video recorders (NVRs) and the different storage options available to you as a first-time buyer. We’ll cover NVR hardware and how to balance footage quality with storage space and network bandwidth.
Hard disc drives continue to get larger all the time, especially when you need them to record megapixel CCTV cameras 24hrs per day.
As unlikely as it seems, we are now headed towards 2 TeraBytes on an SD card!
We’ve covered this topic of MegaBytes, GigaBytes, TeraBytes and PetaBytes before, but we realise that it still confuses people, so we just thought it might be worthwhile mentioning Google’s inbuilt converter and calculation functions for those that aren’t already aware of them.
If you want to know exactly how MegaBytes compares to GigaBytes (or whatever), just type your query into Google’s search box in the following format:
500MB in GB
Google’s first ‘search result’ will be:
 |
500 megabytes = 0.48828125 gigabytes |
You can use this for any conversion using:
KB = KiloBytes
MB = MegaBytes
GB = GigaBytes
TB = TeraBytes
PB = PetaBytes
It also works for other conversions:
4 pounds in kilos
|
4 pounds = 1.81436948 kilograms |
2 feet in cm
|
2 feet = 60.96 centimeters |
Google will also tell you the current time in most World Cities:
time Brisbane
10:18am Wednesday (EST) – Time in Brisbane, Queensland
| Brisbane, California | 4:18pm | -1 day | PST |
Hope that’s handy to know?
