How To Decide How Much Mp I Need In Security Camera
CCTV RESOLUTION STANDARDS
And what they mean
These terms may be used to describe the size of the image captured at the camera, transmitted over a wire, displayed on the screen, or recorded on the hard drive.
When comparing megapixel camera specifications you may notice pixel counts slightly unlike from the above. This is because some cameras will specify the full number of pixels captured by the sensor, and others will specify the 'effective' pixels. Some of the total pixels are used to incorporate technical housekeeping type of information, and are not contributing towards the 'effective' details of the image.
Those of you familiar with CCTV know that the resolution of an analog camera is typically listed as "Tv lines". These "lines" refer to the horizontal resolution of the epitome; therefore a 700 line camera has better resolution than a 420 line photographic camera. Digital video recorders, however, listing their resolution according to the terms in the chart above. DVRs that are 'Total D1' can record all the detail captured past the highest resolution analog cameras.
What Camera Should I buy?
One of the almost common questions nosotros become is "What resolution photographic camera should I buy?" Of course, information technology depends. Each photographic camera in your application may require a dissimilar resolution. It comes down to how much detail you desire, what platform (if any) yous already accept in place, and how much is your upkeep. Examples of applications where y'all can hands justify spending more for higher resolution are recording monetary transactions, desiring facial recognition, or reading license plates.
Information technology is important to consider what platform your camera will be running on equally that may limit your resolution options. To summarize CCTV platforms: Analog cameras transmit over coax and can capture up to 700 lines (approximately total D1). HD-SDI cameras capture higher resolution images then encode / decode the data to run over coax. IP or network cameras transmit over CAT5 (just like computers). You can run analog cameras on a CAT5 network, or IP megapixel cameras over coax, only it would require additional hardware and added complication so it's not recommended.
We do not often recommend HD-SDI cameras because there are shortcomings with the electric current technology (a topic for another give-and-take). Loftier resolution megapixel cameras are fantastic and are becoming more affordable. But don't look results like y'all see in the "CSI" TV shows – that'due south just fiction. And go on in listen that the higher the resolution of the cameras, the more bandwidth and difficult drive infinite you will need to transfer and store it. In nearly cases, cameras over 2MP are normally not worth the extra price (at today's prices), especially because the added costs in required bandwidth and difficult drive storage.
