Review-Dahua SD6CE245U-HNI Starlight PTZ 45x Zoom
how do you weatherproof all the connections if you aren't mounting the camera directly on a building? -

Dahua 4300S vs Hikvision 2032
It seems we're at the part of the program where the forum admin axe-grinds and dahua fanboys back him up. So this is all I'll be adding to this thread. There is enough for someone go on if they care about bandwidth savings. And there is enough criticism for them to weigh against what I said. -

Dahua 4300S vs Hikvision 2032
Nope, I'm not pulling from the substream on either one. I made all kinds of adjustments to the Hik substream and the bandwidth stays the same. When I modify the main stream settings from 15fps to 30fps the bandwidth on the wire clearly changes. Any my Dahua substream is disabled entirely so... -

Dahua 4300S vs Hikvision 2032
Yeah, I'm not going to invest more time creating content for someone who has already decided that it's irrelevant anyway. I gave the settings and the specs for the two cams. I posted pics in the OP but not raw captures but good enough for a fairminded person to see everything I said was at... -

Dahua 4300S vs Hikvision 2032
You keep using that word... irrelevant. Bandwidth is a major aspect of IP cameras. It directly impacts storage space, among other things. If a camera can send the image at 25% of the bandwidth of a different camera, that is 4x as much footage you can store for the same amount of storage space... -

Dahua 4300S vs Hikvision 2032
If Camera A can produce similar quality to Camera B but use 25% of the bandwidth, that is a major thing frankly. Whether or not everyone needs it that's another thing. It's not really hard to point at one feature and say this isn't important to X% of the users. Like I said before, if you... -

Dahua 4300S vs Hikvision 2032
125kBps = 1000kbps. That's what I'm getting with the Dahua more or less. I was actually getting more like 700-800kbps at 720p on the Dahua, VBR or CBR. The Hik checks in at 300kbps (38kBps) for the keyframe and then drops down to 20-40kbps on the non-keyframes. When I first started using... -

Dahua 4300S vs Hikvision 2032
Thanks for the advice. The video quality changes don't really help much. I have one Dahua at 4 and the other at 1. It didn't shave off much bandwidth and the images looked basically the same to my eye. The Dahua only has H264, H264-High, and MJPEG for options on the encoding. I made every... -

Dahua 4300S vs Hikvision 2032
I made up my mind based on hours of tinkering with the Dahua and never cracking below 700kbps for what the Hik could do between 100-300kbps, apples to apples on resolution and fps. I even posted a graph detailing the wire speed on the port that the Hik is connected to. Someone want to show me... -

Dahua 4300S vs Hikvision 2032
My camera model # is IPC-HFW4300S. CMOS identical to the dome. Lens obviously different, though. I'm not watching birdfeeders with a camera directly tied over cat5e to my DVR. These are unmanned remote tower sites in the middle of nowhere that each require 3-5 cameras for good coverage. The... -

Dahua 4300S vs Hikvision 2032
For most applications, the bandwidth is of course irrelevant. At HQ on a gigabit LAN with large hard drives in the DVR it's really irrelevant. However, I probably wouldn't have even bothered with this review if it wasn't for the bandwidth. For remote sites with a small pipe, I think the Hik... -

Dahua 4300S vs Hikvision 2032
Quick contribution based on some experience with both cameras. Bought Dahuas on ebay (from China) Bought Hikvision on Amazon Hik firmware V5.1.0 build 131202 Dahua firmware 2.420.0002.0.R, build: 2014-06-21 Using Synology DS1812+/DS412+ back end for the recording and monitoring of all cameras...
