You can access either via the App/Hik-Connect.
The differences are now those of the cameras and their cabling e.g. one use cat5/6, the other uses co-ax cables.
Resolutions will also differ, although analogue (HD over co-ax) cameras are now available up to 8MP.
That's so nice to hear because I've created a cost breakdown of the two setups I wanted and was blown away by the price difference:
1. DVR: DS-7204HGHI-F1 (720P) - $42
2. Camera: HIKVISION DS-2CE56H0T-ITMF (5MP) - $64 for 2pcs
Total:
$106
1. NVR: Hikvision DS-7604NI-E1/4P (1080P) - $85
2. Camera: Hikvision DS-2CD2143G0-IS (4MP) - $170 for 2pcs
Total:
$255
I have a few more questions though since this is my first time touching dvr/nvrs:
1. Would the specific dvr I chose work fine with Hik-Connect app?
How does it show up on the app? Is it as a dvr/nvr device listed among my separate cameras and if I double click it, I'll get the two feeds connected? Or will the connected cameras be among the devices and not the video recorder? Because on my app since the cameras run independently, they show up as separate cameras and could be stitched together with other cameras. Oh wait I think this video answered my question (youtube.com/watch?v=CyvggDHc75E).
2. Also I have another question regarding the dvr/nvr's resolutions, it's just from their own output right? Like if I connected it to a tv/monitor? If I were to view the live feed from the app, will I still get the camera's resolution that I setup the camera with? (2560 × 1944 in my case for the 5mp one).
3. Also, is there any potential lag/time skips when multiple devices use a single drive? I get a few from my ip cameras with their own memory cards from time to time, not much of a deal break as it's only a few seconds/1-2 minutes but just wondering if there's some major outages with using a single storage?
Again, thank you so much for your help, I'm pretty new to the world of cctvs and I'm glad an extremely experienced user is helping me out.
