What is the difference between 420 TVL and 480 TVL security camera resolutions?Answer
I have a good article that gets much more in depth on resolutions as it relates to CCTV. You visit that page by following this link to CCTV Resolution
So not to sound like I am just getting smart. The difference is 60 lines of resolution. Commonly you will see 380, 420, 480 and 540 resolution options on standard CCTV security cameras. 420 cameras are fine to be used in some locations if you are not wanting that much actual detail. It would be much better to go with a 480 or even all the way to 540 TVL. There are many lower cost cameras manufactured in China that have 420 TVL.
The biggest question is what is the application and then a clear determination can be made on which camera should be used.
