Cctv Security Surveillance - Information to Help You Choose the Right Products for You
Unfortunately this usually ends up with the hard drive failing simply because a pc hard drive is not designed to be constantly "working" twenty four hours a day - seven days a week. Also please check the compatibility of the hard drive with your Digital Video Recorder, as some may require IDE drives, others SATA, and some may work better with Seagate, others Maxtor. Ok, now hopefully you have a better idea about what a Digital Video Recorder is, and its purpose, now let's consider the Cameras. CCTV Camera Basics...For those who know little or nothing about what a CCTV camera is, or what it does.CCTV Cameras are the "eyes" of a CCTV system, you place them inside and outside buildings to enable you to see and also record (via a Digital Video Recorder) what the camera is looking at. Unfortunately that's where it stops being easy, we cant emphasize enough how you need to educate yourself as much as possible about what CCTV cameras are capable of and then look seriously as to what you want to use a camera for and what you need that camera to do. By this we mean there are literally thousands of cameras available nowadays, but this is because there are so many different situations where a camera is required that there isn't just one camera for all jobs. So how do you go about choosing a camera, well you have to start with basics....First where is the camera going? Indoors or outdoors? If outdoors use the weatherproof guide to choose what kind of an IP rating your camera requires.Weather Proof Rating...Weather proof is measured using an IP Rating, if a camera doesn't state an IP rating you can consider it is for internal use only.IP Ratings GuideThe IP classification system designates the degree of protection provided by an enclosure against solid objects or water ingress.There are always two digits in an IP rating, the first digit refers to the protection against solid objects (dust) and the second digit refers to the protection against water.Dust Protection (first digit):0 = Non-protected1 = Protected against a solid object greater than 50mm, such as a hand.2 = Protected against a solid object greater than 12.5mm, such as a finger.3 = Protected against a solid object greater than 2.5mm, such as wire or a tool.4 = Protected against a solid object greater than 1.0mm, such as wire or thin strips.5 = Dust-protected.Pages: 1 2 3 [4] 5 6

WoTLK Secrets Guide - The Best Way to Make Money in WoTLK ReviewWoTLK Secrets Guide - The Best Way to Make Money in WoTLK ReviewAuthor: Brett BarringtonRecently I was wondering what kind of guides were out for WoTLK. When a new expansion comes out there are always undiscovered bugs and way to make crazy amounts of gold. I started my venture through the web and came across " WoTLK Secrets " guide. It had a nice cover, and a very informative landing page. I also saw they were a clickbank publisher, so if they were to scam me I would easily get my money back within 8 weeks. |
Top Ten Reasons to HomeschoolTop Ten Reasons to HomeschoolAuthor: Julie ClarkAs I approach this topic, I realize how ridiculous it is to assume that I can write about "THE" Top 10 reasons to homeschool. One of the main reasons to homeschool your children is that you can be at the helm. You can do it for whatever reason you want in whatever way you want, so for me to assume that I could come up with the definitive top ten reasons seems kind of silly. My top 10 reasons are top ten for me. There are many homeschooling families I know whose reasons are vastly different from mine. |
