hmm, Wannker,
As with many newer HD alanlog DVRs, it WILL accept one or more IP cameras.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Limited Budget? One Price Enjoys Three Modes Switch
DVR: 8CH@1080N/ 8CH@720P
HVR: 4CH@720P (Analog) + 4CH@720P(network) IP Camera
NVR: 2CH@1080P+2CH@720P/ 8CH 720P IP Cameras
*IP Cameras must support ONVIF
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
AHD is generally not as good video as the newer CVI or TVI proprietary formats, but it does seem like a reasonable starter system,
- jack
NOTE: I am a little confused by the "1080N" which seems to be a made-up designation. I can find nothing on the internet with a good definition, though it MAY be a variation of 1080i with reduced horizontal pixels that actually comes out to more like the stretched TVL format.
(from wikipedia under 1080i)
"Some cameras and broadcast systems that use 1080 vertical lines per frame do not actually use the full 1920 pixels of a nominal 1080i picture for image capture and encoding. Common subsampling ratios include 3/4 (resulting in 1440x1080i frame resolution) and 1/2 (resulting in 960x1080i frame resolution). Where used, the lower horizontal resolution is scaled to capture and/or display a full-sized picture. Using half horizontal resolution and only one field of each frame (possibly with added anti-alias filtering or progressive capture) results in the format known as qHD, which has frame resolution 960x540 and 30 or 25 frames per second."

My educated guess: 1080N (N stands for narrow) is 960x1080 or half of 1920x1080. If an AHD 1080-line camera is plugged into this DVR, the DVR will only sample 960 pixels per line so the slower (cheaper) H.264 encoder circuit can still handle the task (1080N30 = 31Mpix/s is similar to 720p30 = 28Mpix/s which is half of 1080p30 = 62Mpix/s). When displayed 1080N is stretch back to the original 16:9 aspect ratio.

Note that with analog HD cameras, the vertical resolution is fixed but the horizontal resolution is more "nominal" than "explicit", just like the TVL of analog cameras. The sampling hardware determines the horizontal resolution of the digital image/video.

Old analog non-HD DVRs work in the same principle. HD1 (NTSC) = 352x480 is half of D1 = 704x480. HD1 was popular back in the days when HDDs were much smaller (think 160~320GB max capacity for a 4~16(!!) channel DVR) and expensive. Fast hardware encoders still cost more (my first 4-chan analog DVR from 2010 could encode D1 at 7fps/ch, HD1 at 15fps/ch or CIF at 30fps/ch, and it's still not uncommon for 2-year-old mid/low-end DVRs like Q-See to encode at 15fps/ch instead of 30 if all channels are in use). Also, old Super VCD (SVCD) resolution was 480x480, 2/3 the resolution of 720x480 DVD.

yup, most low-end surveillance systems will record a distorted digital interpretation of analog source, and won't exactly scream-out that simultaneously recording cameras will be less than half the quality.

just imagine a thief putting a naked Trump in front of your main cam, and he's masked breaking into your least defended point-of-entry. not exactly exHillaryting.

Hmm, so, since IP cameras do the processing in-camera, this limited system might do quite nicely with several IP cams even though it may struggle with AHD input?? Am I interpreting you correctly?

And, thanks for the informative reply!! Maybe you should add a Wikipedia page for 1080N??

I am so surprised to learn there are so many deals pops-up about surveillance system on SD and folks are pulling trigger on them. I hardly ever see anyone concern about the lens size, or will it accept OnVif, or such a features.

No wonder why Mr. SD is a millionaire dude and hide under a closet all the time, since he indirectly pull people into buying shiatt from SD.

No, only 4 cameras with very limited view area and quality. Can find better deals with better specs at same price.

If you can wait just a few more months, you;ll find much better deals (of the year) coming up starting in late October and through the holiday buying season.

Should have decent systems with 8 cameras (probably around 3 MP), 1TB drive, for around $199 to $229 range.

I picked up mine with 8 cameras last BF time around for $179. So if not needed right now..just wait a few more months. Smilie

I'd like to get a significantly better system than this. Is there a system out there that is really considered to be exceptional?
