• How many cameras do you need? Decide how many locations you want monitored, such as doors, windows, driveway etc. This will give you an idea of how many cameras you will want included in your security system. Most security camera systems come with one or two cameras. If you might need to add more cameras, make sure the system you choose is capable of adding more cameras later.
Security cameras, though not the least expensive of options, is probably the most sound in your decision as a business or homeowner. Surveillance cameras that will spy into any number of nooks and crannies of your business or home, offer unbridled protection in the form of visual proof; proof that without a security camera system would have never been attainable prior to its installation.
• DVR. This is a hard drive that allows you to record and playback the video feed from the security system. When the memory becomes full, the new video signal will then overwrite the oldest one. There are some systems that have memories large enough to record 150 days worth of footage.
