What resolution is 400 TVL?
TVL is defined as the maximum number of alternating light and dark vertical lines that can be resolved per picture height. A resolution of 400 TVL means that 200 distinct dark vertical lines and 200 distinct white vertical lines can be counted over a horizontal span equal to the height of the picture.
What is 1000 TVL resolution?
One of the biggest flaws of current analog technology is that the highest analog recording resolution is 960H (960×480), or 960 horizontal lines, but 1000 TVL cameras typically have 1280×960 pixels, or 1280 horizontal lines. This results in forced recording at 960H, even if the camera has higher resolution.
What does TVL stand for in Crypto?

What is 700TVL camera?
960H is the new analog technology allow cameras and DVRs to capture up to 700TVL, the highest TVL available to date. 960H represents the number of horizontal pixels in the CCD image sensor. The greater the resolution, the higher the definition of the video image.
Is there a difference between 700 TVL and 1000 TVL cameras?
A: Yep. Exactly the same thing, except that sometimes 1000TVL cameras are actually mislabeled 700 TVL or 720P cameras – translating from Chinese to English is difficult! Even if you have 1000 TVL image sensor in the camera, you can’t cram more than 720 TV Lines down the cable and into your IP Camera DVR.
What does 700tvl mean on a HD monitor?
TVL refers the horizontal pixels on your monitor. HD resolutions measure the vertical pixels. This chart is used to test the resolution of TVL cameras. Most 700TVL cameras can only decipher up to 525 TV Lines.
What is the resolution of a 1000tvl camera?
Using this “creative math,” that 1000TVL camera would really be a 750TVL camera. But since Analog DVRs max out at 720TVL anyhow, nothing beyond that matters. This chart is used to test the resolution of TVL cameras. Most 700TVL cameras can only decipher up to 525 TV Lines.
Is the TVL standard a made up standard?
TVL as a measurement standard has always been mostly made up since the beginning. When TVL was the normal way to measure camera resolution, manufacturers made up their own formula to make their cameras sound a little bit more appealing.
