Hikvision 16 channels 7700 vs 7600 series NVR comparison?

[Charles.Porette]

Hello all,
Apart from basic hardware specs, can anyone give me an idea of the actual performance gaps between these two NVR lines?
I’m trying to get a comparison before I buy, just to see if the 16 channels 7700 features really justify the increased price over the 7600.

What are the main differences I should look at, to help me decide?
Thanks

Hello,
Looking at the datasheet of both NVRs, we can see the following:

Feature	DS-7716NI-M4	DS-7616NI-M2
IP Channels	16	16
HDD Bays	4 SATA	2 SATA
Maximum HDD Size	16TB per HDD	16TB per HDD
Max incoming/outgoing Bandwidth	256 Mbps	256 Mbps
Chassis Type	Rackmount (1.5U class)	Desktop
Video Outputs	2 × Independent HDMI/VGA + 1 × BNC	1 × Independent HDMI/VGA + 1 × BNC
Alarm Inputs / Outputs	16 In / 9 Out	4 In / 1 Out

So if you require more storage capability to record for longer period, more alarm input and outputs and the option to have multiple monitors for live view then the 77 series is better.
Decoding capability are the same on both recorders. 16 channels @1080p
Please bear in mind that mouse control can only be done in only 1 video output at the time.
Always consult your installer and look on the datasheet of the product for further details.
