You can have other browsers run an Internet Explorer inside a tab (like, google "IE tab" for Chrome or Firefox). But you will still be running Internet Explorer, since other web browsers can not execute ActiveX.

Yeah, I am always used to PAL numbers. 100fps@1080p PAL or 120fps@1080p NTSC. Thanks!

I am subscribing to this thread hoping that someone can tell if the fps can be split among several cameras. Like, 3216 can record 400fps@D1, 200fps@720p, or 100fps@1080p. I assumed that with that you could record 4 cameras at 1080p 25fps each camera, but that maybe you could also record 8 cameras at 1080p 12fps each camera. So, that the total fps that the NVR can record at a given resolution can be split between several cameras. Is that so? Can someone correct me if I am wrong?

Wow... I would love to be able to charge $1500/camera

I am seting up a Dahua 0404LF-AS with two alarm inputs for triggering push alerts and email messages. On Alarm1 input I have connected a PIR sensor, no problem here. When the PIR detects motion detection it warns the DVR, which then triggers a given action. On Alarm2, I want to connect a door bell that currently works at 220v. This way when someone rings the bell, I make the DVR send an email with a screenshot of the door camera. Question is, how can I connect this 220v to an alarm input? I am quite sure that inputing 220v on an alarm input is not a good idea, but how about 12v? Or what do I need to connect those 220v to an alarm input? Thanks!

Well, the door bell seems to be quite standard, at least here in Spain. I went to check for new door bells this morning to an electrical supplies shop, and they had like 8-10 different models, all of them were 220v. I checked one out, and to me it did seem that it was about the same thing that is currently installed. I asked if they were ok, and they say it is legal to have 220v door bells.

I am not an electrician. I did ask an honest question when I asked what is the risk. What is the difference between this button+bell, and any button+light bulb which also works at 220v? If I was to remove the bell and put a light bulb on its place taht would be "safe", but the bell is not safe? I really do not get it. I do not see this having any more risk than any 220v light bulb, and I do not see myself telling anyone to replace all their house lights with 12v led lights becuse they are safer, and that 220v lights are not OK any more.

If you have 2 routers, one behind the other, you have to configure them both. From your ISP's router you have to forward the ports to your router's IP; and then from your router you have to forward the ports to your DVR. You have to understand that this is an inbound connection, someone on the outside of the network is connecting on the network to see your DVR. The connection comes from the internet, so your ISP router needs to know where to send it too, which is your inside router. And then your router needs to know also where to send a connection to a given port, your DVR's IP.

ak359 please don't missunderstand me, I do not mean to be rude and I do appreciate the help on this forum; but I am here installing the CCTV system, and I was asked if it was possible to wire one alarm input so it will alert when someone rings the bell. That is my task, I really have no need to replace the bell, the front door button, etc, unless I think there is some risk on how it is set up right now, and I am really unable to see any problem on how it is currently working. Thanks!

Tom, I tried to get back on topic, but it didn't seem to work; we install CCTV, not door bells. I am really not that much interested on knowing what doorbells spanish law allows, since I have never installed any, and I doubt I will. But even then, I don't see the point on 220v bells being forbidden. 220v light bulbs are allowed, right? I can have a button that will turn on a 220v light bulb, but not a 220v door bell? Could someone explain me the difference? 1, I am not sure what you are saying there; but I am geting voltage reading because I am pushing the button outside the door while I am taking that picture. 2, It has no earth. But I will say it again, any light bulb also does not. Are they also unsafe? If you found something that is actually 35E and that I can use to replace this bell with and will also give me a relay output, please feel free to post a link. Otherwise, this thread really was not meant to be a thread about replacing a door bell, but a thread on how to connect from 220v, to an alarm input on a DVR... Thanks!

Aaaah, of course... I was always thinking on puting a 220v to 12v in there; but since I am not able to just connect 12v to the alarm input, it will be easier to buy a 220v relay, than a 12v relay with a 220v to 12v adapter. I see if I can find one tomorrow, thanks!

Those 220v are not "outside", this is not a home, but an apartment (the other side of the door is not "outdoors"). No idea on how one of this bells/chimes are supposed to work, but from what I have googled it seems quite common to have them work at 220v. In fact this one seems to be manufactured in 96/97, so it is not that old. Not sure what kind of button you expect on the other side of the door, but the only difference with one you would use to turn on/off lights is that this one turns off when you stop pushing. Anyway; I tried using one small 1.5V battery to close the alarm input, it did not do anything. I tried with two batteries (3V), it also didn't do anything. I tried with a 9V battery, no luck. I just tried with two cables, and it did work. So I guess it just can not be activated with any voltage, so I think I just need a 12v relay, something like this: http://www.ehow.com/how_7224593_wire-12v-relay.html

So it is 220v, and the chime seems to be just some electromagnet that will make a metal part inside hit the metals on top and bottom. What is sure is that I have 220v, so the question stands, how could I connect a 220v input to a DVR alarm input? Should I just convert it to 12v and input those 12v, or will I fry the DVR? Thanks! Edit: I could probably connect it like tomcctv says, using the button on the outside, but geting my cable there would be a pain in the ass. Not impossible, but something I would rather not do.

There is no jumper on SATA HDs, and being a WD AV-GP 1.5Tb HD it is surely SATA. Master/slave jumpers are only for IDE (ATA) HDs.

Ok, I will take my tester with me today so I can check it again at home, and see what is under the CE plastic cover. Thanks!

At the front door button? I will try to do so tonight, I do not have the tester with me. But on the chime/bell which is where I will be conecting myself, I have 220v. But if I can input 12v on the Dahua alarm input, that would be no problem, I could just connect a 220v->12v power supply on the chime, and from there to the alarm input. I just did not want to try that without being sure that conecting 12v to an alarm input is safe.

I also use mainly wide screen resolution setups, and I have never had a problem with PSS. I am right now at 1920x1080 and PSS adjusts perfect to use all the available space.

Sorry, I am not native english so I did not explain myself right. Maybe I should have said my "chime", bell... and it surely does work with 220v, I did test it to make sure. And there is no "back door button", just one outside that will make the bell ring inside. So, when someone pushes the button outside the door, the bell inside gets 220v and it rings. Here is picture.

If the leds are always on, I would say those are defective cameras. Image might be better or worse depending on the camera quality, but the leds should turn off when the ambient light is enough to work in colour mode.

I guess that is the reason why Dahua and DVR manufacturers in general do not put for download firmwares on their web sites... The fact that your DVR is 0404LE-AS and the firmware filename says xx04LH-X should have ring a bell.

Camera not powered up, non working camera, bad cabling, PAL/NTSC setting opn your DVR wrong, ... who knows. Try to connect one of those cameras directo to a TV to see if you get any video.

Check your DVR box for accessories, it probably comes with your DVR.

You do not need a hard disk installed in order the view the cameras live.

It does have RS485, so you can indeed control the OSD menus from the DVR!

The camera is the one you linked above? Because that one is an analog camera, and it does not say anything about RJ45 or RS485.
