So in summary, the Bosch Divar 2000 is to Dahua what the Cadillac Catera was to the Chevy Malibu...
Wrap it however you want, it’s still the same under the hood.

Thats pretty cool. Wonder how much it costs bosch to add all the additional hardware and software features. Its like they took everything I dont like about Dahua and fixed it.

We have started using these appliances and they have worked great so far. For motion recording on Axis cameras you have to set them up in the camera for that to work on most models but not all. Also this works with their BVMS video client as well to have a better interface for the recorder. I believe it is free up to 5 recorders.

Maybe a cheap German product, but they couldn't keep their German mitts off it to make it at least a little better.

Are there any other OEMs besides Bosch that do more than just cosmetic changes? Bosch appears to have taken the extra step of remedying defects in the product as well as other items under the hood that would go unappreciated if not for this article.

Where the main boards the same on the Dahua and Bosch or was it just a general comparison?
Typically Dahua say that Dahua branded units will always have the newest features first and that OEM's don't get them for months later, while true in certain cases if you really want something you can get whatever you need from a software prospective.

What about noise levels? Bosch fan looks faster and might be noisier than Dahua’s.
Both units doesn’t seem rack-mountable, so fan noise might be disturbing when installed in a living/working area.
Fans used by Dahua for their dvr’s are very noisy and traditionally had quality issues over the years. They don’t seem to implement any acoustic engineering into their designs.

So no direct driver support for Bosch cameras?
Since one would expect the direct drivers for Axis/Samsung etc, could have been enabled, had Bosch desired it, why do you suppose they didn't?

This Divar IP product line from Bosch has a great price/value ratio, but unfortunately they have nothing to offer for systems between 32-128 channels in this product line, from 32 cameras you have to go for their pricey iSCSI servers.
There should be a DIVAR NVR for 64 and 128 channels but at least a 64 channel NVR.

Hmm. I wouldn't really say Digest authentication is significantly more secure than Basic authentication.
If an attacker holds a privileged position on the network and are able to intercept and tamper wirh your traffic, and you are either using HTTP or HTTPS with self-signed certificates, you can just downgrade the authentication to Basic and see the password.
If they are using HTTP or HTTPS with self-signed certificates, and all they can do is sniff your traffic, then most passwords can be found by brute-force using Digest.
