One of the questions you may ask is:
The simple answer is yes, but the newest generation of digital cameras, are much better than the analog cameras of as recently as 4-5 years ago. You may say, “I spent a fortune on the cameras. They must be good!” Well, is the VCR that cost $2,000.00 two decades ago better then the one you can pick up at WalMart today for $89.00? The answer is a resounding no.
In fact, to the contrary, it is a technologically inferior dinosaur. Much the same can be said for surveillance cameras. It is most evident in the sharpness and quality of the picture. If you're still unsure, try replacing only a few of the old ones with the new ones, or if you're putting in some additional camera locations, install those first, then compare and make your decision.
The first thing to know is the cameras don't have to all be the same type. DVR's can accept all different kinds of CCTV cameras, so you can mix them as you wish; color with black and white; pan/tilt with bullets, indoors with outdoors, 24 volt with 12 volt, etc.
There are a number of factors that go into making a camera selection:
• Indoor vs. Outdoor
• Environmental Conditions
• Mounting Locations
• Lighting Conditions
• Size of area to be captured
• Quality of the image required
• Available power and type
• Vandalism concerns
• Distance from DVR
• Color or Black & White
• Security objective
On the following pages we will address these one by one. Additionally, we will educate you as to a general understanding of some not-so-obvious differences.
