What price point are you trying to meet? Are there any specific requirements other than video and audio? Onvif?

This is a hugely popular place to position PTZ cameras. It's usually about watching money exchanging hands and keeping an eye on the business' employees, not about recording someones pin assuming it's even focused in on that. I specifically see this a lot with pawn shops, medical marijuana dispensaries, and small businesses.

Dahua produces Tribrid DVRs compatible with SD analog (TVL), HDCVI, and IP cameras. I don't believe anything is made that does only TVL and HDCVI.

You're correct about that problem with the IR at night. I can't tell you how much more spectacular it should be, but that dish is definitely causing you the issue.

It's not technically backwards compatible, but there are Hybrids and Tribrids that can do multiple cameras types; to include SD analog, HDSDI, HDCVI, and IP. I want to say there's a Tribrid option for HDTVI now, but I could be wrong. To go along with what survtech said, I would toss the idea of HDSDI away. It's cheaper now but it's remarkably inconsistent.

FPS is definitely just an annoying carry over that most sellers still use to advertise NVRs. The only thing I can figure is that they assume most people aren't going to know it any other way than that. There's obviously a lot of confusion as a result. I never know how to make this simple for customers who don't understand the technology in general. Hopefully you can just explain it like MaxIcon did, and your customer will just accept it without understanding it and move on.

Let me clarify. My DVR can update to no-ip fine on its own; I can even do that using a router if I wanted. What I need is a known open source DDNS server script out there that is compatible with Dahua DVRs. That way I can host that script on my own server, and let the DVR update to that server. I'm trying to get around using a paid DDNS service, or a free one that requires me to update my info every 30 days. I'm also trying to dodge using Dahua's DDNS service.

Does anyone know of an open source DDNS server script that's compatible with Dahua DVRs; the idea being to host your own DDNS server.

Try formatting it to FAT32

Is this a joke? You understand that CCTV is not solely limited to simple plug-and-play systems right? Do you have any experience in this field at all?

1. Video is backed up in the DAV format but can be backed up in either DAV or ASF 2. You are correct, 1080p playback 3. Tribrids support up to 3MP for sure. It didn't like it when I tried 5MP 4. Up to 1080p real time recording As far as where to get it: http://goo.gl/3koh6S I've been warned three times now about Nelly's Security apparently completely lacking in customer support so my advice is to be careful about what you purchase from them.

1.1Kbps or 1.1Mbps... 1.1Kbps is the slowest upload I've ever even heard of. If you were in the US, I'd tell you there's no possible way you're ever going to connect remotely if your upload speed is 1.1Kbps. I can't speak for other countries but I imagine it has to be similar.

I would like to see someone who knows something about AHD respond to this. AHD seems to barely be hitting the market, and I keep getting told that it's inferior to HDCVI and HDTVI but no one is able to offer up a reason as to why. I wish I had answers to your questions, but the answers are either a matter of opinion, or I'm just lacking credible sources of information right now. I will say that HDCVI is more time tested (albeit a short amount of time) and so far has a smaller failure rate than anything I've ever dealt with. We'll see what happens with that failure rate when people start to find cheaper ways of manufacturing it.

What's the upload speed?

I'm also tempted to assume that it's a very cheap/basic router. I'd be curious to know what the make and model it is though.

I think you can probably toss the idea of PTZ cameras aside. There's not a real good chance of that fitting into your budget.

The only time I've seen something like this happen is when too many cameras are simultaneously being triggered to record on motion at once. It was also with a nearly identical DVR. In my case, there just wasn't enough processing power to handle so many cameras being triggered all at once. As far as those motion settings not being present, they're usually found under the "Detect" section. If all of that is absent from the DVR, I would look for a new version of the firmware. I've never seen those missing before.

Tribrid DVRs (analog, HDCVI/HDTVI, IP) are definitely the better way to go. I wouldn't even be considering a Hybrid (analog, IP) anymore now that Tribrids are readily available and have more processing power. I actually think that Hybrids are going to start being phased out if they don't start making them more powerful. Whether you choose a model for HDCVI or HDTVI is entirely up to you. I'm more partial to Dahua than Hikvision, so I'd personally opt for HDCVI, but that's me and I honestly don't think it will make a difference as far as quality is concerned. Make up your mind now though about which type of HD camera you want to upgrade to later. It'll help to avoid running new cable later instead of just using existing cable at that time. I stick with IP whenever it's in the budget.

Dahua doesn't allow sellers to display the Dahua name on their products. Dahua actually went through sites like eBay and Amazon a couple years ago and removed a lot of sellers privileges to sell Dahua products because they were in violation of this. Since I see it all over those sites again now though, I think they've relaxed a little bit, but as far as I know, their policy has still not changed. All of this kind of makes it a pain in the but for first time buyers to verify that they're actually receiving a genuine product. Amazon for instance is full of people who just clone ASIN numbers and sell cheaper versions. It's totally unregulated, and unfortunately, buying from an actually e-commerce store isn't always the solution.

The screw indicated here doesn't allow you to manipulate anything?

It looks like you just need to loosen both of those screws on the arm. One will let you rotate the arm inside the base and the other will let you rotate the camera on the arm. Just loosen everything up and twist and turn until you get the right angle. That's a standard "3-axis" bracket from what I can tell.

Is this a digital wireless camera by any chance?

Can you take some additional pictures of the camera or link to it. I believe you just need to loosen a detent toward the bottom of the arm and the whole thing will swivel inside of the base.

If you're happy with it, why not just buy another one and add an access point to it to make it wireless?

This is a pretty desperate attempt for a backlink...
