800tvl Vs 1080p Vs 720p

Measurements in TVL refer to the horizontal pixels of the image, while HD resolutions measure the vertical pixels on the image. This means that 720p, which is 720 pixels tall by 1280 pixels wide, is actually a better image than 1000TVL.
Next, we shot out the 960H camera, the top analog performer, against 720p and 1080p HD IP cameras in order to show the differences between these two technologies. The IP cameras easily deliver more details than 960H, with more lines legible on the test chart, and much better details of our subject's face.
In order to see if 960H could compete with HD at any field of view, we widened the 1080p camera's field of view to double that of the 960H camera. This comparison shows the relative field of view of each, as well as a zoom view of our subject. Even at a FOV this wide, 1080p still beats out the analog camera, with better details of subject and chart.
Good morning John, and thanks for the shootout. We do them here with some frequency. My question to you and to the industry is this. Why do IP or 1080p cameras \"appear\" to perform so poorly at night or low light Is it just a matter of product maturation or is there something inherent in the devices, in your opinion
1080p generally does perform worse in low light than lower resolution cameras, which you can see in a lot of our shootouts. Though the gap is narrowing somewhat, based on some recent cameras we're working with.
When TVL is used to describe the video resolution of security cameras, most of the time people are referring to analog CCTV cameras. HD security camera resolutions, on the other hand, are more commonly referred to as 720p, 1080p, 2 megapixel, 3 megapixel, 5 megapixel, etc.
