Security cameras are one of the most important tools for security but they are extremely difficult to choose as they have vast variety. So for security cameras installation you should know exactly which one will work for you. Here are some tips on how to choose the best affordable security camera by cctvinstallation-losangeles.com which is the first digital surveillance.
you’ll have to look first at resolution mainly because that’s what’s talked about most commonly first when picking cameras so you can see here you know VGA is sort of your legacy type resolution and then there is 1080p and 720p three megapixel four megapixel five megapixel surveillance cameras. you’ll see going up into ten twenty megapixel ranges we’d recommend that you start with at least 720p you certainly can go higher 1080p s become increasingly standard as we move closer to the end of the decade surely more and more will be for instance five megapixel or 6 megapixel
DECIDE THE FORM
Form factor matters the most in security cameras. The most common form factor is domed, these round camera type and then next are bullets, more specialty some people use PT Z’s for pan tilt zoom mechanically and then finally box cameras are for more professional usage when you’re doing specialized applications.
To determine the best camera free for your needs, you need to choose between Vera and fixed focal lenses now if you choose fixed focal lenses you’re usually less expensive cameras but you can adjust the field of view so if you want to adjust the field of view later and really optimize it in you’re gonna want to choose variable focal cameras also if you care about focusing it or having the camera focus itself you may want to choose auto focusing and that’s only available in more expensive cameras now.
A few other things that are really important when you’re looking at video surveillance or security cameras imaging so if you have a scene where you have harsh backlighting you’re going to want to choose true WDR surveillance cameras
If you want a camera that does at least 3 megapixels 30 frames per second and you want it to be under $400 and you can see for instance what your options are for that and of course you could go over and you’ll see no cameras because 3 megapixels 30 frames per second is pretty high but if we went to 3 megapixel 14 frames per second all of a sudden we have 80 cameras so we’d recommend that you experiment.
IMAGE COMPRESSION ALGORITHM
The type of the carrier does not matter, an average or good video encoding and compression algorithm is needed. An algorithm can compress the video code stream and storage capacity as much as possible without compromising the image quality and clarity. Poor IP high-definition cameras can easily produce blur image or dots under large movements, which directly affect video image quality.
