TVI vs AHD 1080p HD Security Camera Comparison

TVI vs AHD. Which HD security camera type
is best? This is a common question that we receive at CCTV Camera Pros. This video will
compare TVI vs AHD by looking at normal light and infrared video surveillance captured by
2 cameras with identical specs. Here are the 2 cameras that we use for our test. The 2
cameras are virtually identical. Both capture 1080p HD video over coax cable. They are both
enclosed in the same IP68 weatherproof housing. They have the same number of infrared LEDs,
and they both have a 2.8 to 12 millimeter varifocal lens. The only difference is that
one uses a TVI processor and firmware, and the other uses AHD. You can learn more about
each camera by clicking on or visiting these URLs. Here’s the video surveillance footage captured
by the TVI camera. I have all the lights on in the warehouse initially, so that you can
see the color daytime mode. Next I turn all the lights off in the warehouse, so that you
can see the infrared video captured by the TVI camera. Notice how the infrared of this
camera evenly illuminates this entire space. When I turn the lights back on, the infrared
mode is turned off, and the camera captures color video again. Now you will see the surveillance video captured
by the AHD camera. The camera is installed in the exact same spot. We start with the
lights on in the warehouse, just as we did with the TVI test. Although the colors are
a little different, the clarity of the video from the AHD camera is very similar on quality
to the TVI camera. Those letters on the Siamese Kale boxes may be just a little bit clearer
with the TVI camera. I think that I like the color of the AHD a little better though. The
infrared performance is similar too. The IR LEDs on the HD camera illuminate this entire
space adequately, and the video looks just as clear. To capture the video surveillance footage,
both cameras were connected to an iDVR-PRO Hybrid DVR that works with both AHD and TVI
cameras. The iDVR-PRO also works with standard definition analogue CCTV cameras. Here’s a
side-by-side comparison of the normal light and infrared images that I captured from those
videos. In my opinion, these 2 cameras are pretty equal in both daytime and nighttime
infrared performance. I thought the TVI camera may be a little clearer, but now that I’m
looking at the still images, I noticed that the TVI’s camera angle is a bit more narrow
and zoomed in. Notice that the AHD’s view extends beyond
the edge of that shelf in the warehouse, but the TVI camera cuts it off. This may be the
reason that the letters on those boxes are just a touch more clear on the TVI video.
In my opinion, TVI and AHD cameras are pretty equal in performance when you’re comparing
cameras with the exact same spec otherwise. You can see my complete write-up on TVI vs
AHD on this webpage. The page also contains additional information and additional HD photos
captured during my testing. Thank you for watching.

  1. it's about time we see some clear comparison! Thanks for doing this. We have been getting 500 feet out of HD TVI and have seen reports of 1000 feet no problem. The spec is 1500 feet. What's the distance spec and your experience with AHD? So far we have been exclusively HD TVI for analog transmission video surveillance. There's rumor that 3 megapixel+ will be available soon. Any word. Thanks for another great video. Thumbs up here

    Oh and by the way things for serving!

  2. Thank you for this great video comparison. The TVI in this video looks much better than other video comparisons such as this one.
    Do you have an article on TVL? It is extremely confusing. For example, I purchased a NTSC 1080TVL (Thinking it was a 1080TVI) unit but when hooking it up to my hybrid DVR it shows up as WD1 (960 x 480). Is there equipment that uses 1080TVL with better resolution than WD1? If so, what is the maximum resolution? There are 700TVL, 800TVL, 1000TVL, etc. What is the difference? .. my understanding is the vertical resolution is 75% of the TVL number … but I also have read over and over that the maximum lines or resolution is 480 with NTSC. Confusing. Thank you.

  3. Those models have…. identic only lenses and housing….
    What sensor is inside TVI camera? What sensor is inside AHD camera?
    What DSP is on TVI / AHD cameras? Propably totally diffrent, and propably totally diffrent settings are set in each one camera.

    In AHD cameras, mostly is installed NVP2441H – where sharpness is set too low, 3D/2DDNR functions are set too high.
    In TVI cameras – mostly inside is Techpoint chip – where sharpness is alredy set high, DNR – low.

    I think – nowadays, its better to compare cameras as nextchip release 4in1 dsp.

  4. Don't simply state that AHD is better just because you did not have the same focal length on the AHD & TVI. If you are professional enough please do a comparison with same focal length as you stated both the camera is varifocal. Also, have you tested TVI camera with other brands of TVI DVR?

  5. Hi, I'm in the business for a number of years too. The angle of the camera depend much more than the lens that it come with and with the vari-focal lens comparison, I doubt you can come up with an accurate assessment. Your method should satisfy most comparison test casually. It just that the way they manufacture the camera varies vastly. The type of chip combination with the DSP and the size of the CCD or CMO can affect it. Also the fact that how they configure the format of image also play a huge factor since a lot of manufacturers change the setting to accommodate or hide the shortcoming of an image. In this case, the TVI camera can have the same angle but because doing so will showcase the unevenness of it's infrared red at the edge they decide to trim it off instead. If you want to do the most accurate comparison between AHD and TVI then I'll advise you to get a 3.6mm hikvision and a samsung AHD to run a test instead.

  6. tvi ? think you mean tvl Television lines (TVL) is a specification of an analog camera's or monitors's horizontal resolution power. It is alternatively known as Lines of Horizontal Resolution (LoHR) or lines of resolution.

  7. Not once did you mention price comparison. We don't need to know exactly what each cam costs specifically, but we do need to know if we should expect to pay twice as much for one over the other for example

  8. With the quality of the TVI I can only see you in the foreground, but with the AHD I can actually see the black guy in the background stealing your computer.

  9. This is an excellent explanatory demonstration. I'm trying to decide what equipment to acquire, and this video answered a number of my questions. Thank you so much.

  10. It seems to me that TVI was winning in clarity and AHD in color. Now which one would be more important in this case? Clarity, when your trying to review details.
