    Camera CMOS size vs F stop.

    Yes, this publication is very instructive and I have it bookmarked and always make use of it. I didn't know that boy had died.

    Camera CMOS size vs F stop.

    Hello, good morning. Here is a forum guide that also explains every feature of the camera very well. https://ipcamtalk.com/threads/is-there-a-such-thing-as-a-camera-system-that-is-not-complete-trash-suggestions.65181/#post-692706

    Choose PTZ camera for weather station

    But if by any chance lightning strikes the camera, first of all it will destroy absolutely everything, and then the cable, which will be 1.5 mm copper, will never be able to withstand such a large amount of energy. What I have told you before in other messages about the installation of the...

    Yes, you mean that it can be a lightning attractor because it is directly connected to the house installation. I understand that it is not necessary to connect it, the only thing you can do is to put a retractable thermos and leave it insulated so that it does not rust.

    Choose PTZ camera for weather station

    The mast has to be attached to the wall, but it won't have a dedicated ground wire. The only thing I can do is to pull out an extra wire and connect it to the ground of any socket in the house, which is to dismantle the three-wire box and connect it to the yellow/green one. This is the best...

    Dahuas from Taobao in 2023

    Yes, I realised later that I hadn't added the name, but you were already writing the message. Now I have modified it and you can access it.

    Dahuas from Taobao in 2023

    In these matters, you never know what can happen, because you also never know where these cameras have been and in whose hands they have been. They may work very well and you may be able to upgrade without a problem, or you may have problems when upgrading. As a recommendation, you could ask...

    Choose PTZ camera for weather station

    There are the three wires together coming out from inside the camera, but I am not going to disassemble the camera to see where it goes. I understand that it's going to be the cable like any electrical appliance so that if there is any leakage of electricity, it will go through this cable and...

    Choose PTZ camera for weather station

    This is the yellow cable used in the home for when there is a power failure and it goes to the iron pole that is half a metre into the ground (which should be in every house). Well, I understand that the cable that carries the camera will have to be connected there, but well, as I have my doubts...

    Choose PTZ camera for weather station

    Hello again. Yesterday the blacksmith came to take measurements of the mast (he also had to take measurements of some mosquito nets), and I wanted to ask you something about the power cables of this camera. The power adapter has only two wires, positive and negative, but the camera has a third...

    Options for mounting a IPC-Color4K-T180

    Yes, I have seen that by putting 2 you were able to correct the part of the plaster ceiling, and now it looks very good (the lower part where the camera is very close to the shelf could not be corrected, but I understand that it is because it is very close to the camera). The camera has to be...

    OK, I had been to that option but I didn't quite understand what it was for. Thank you very much, I will check it out.

    Options for mounting a IPC-Color4K-T180

    I understand that as the camera is displaying straight lines, the difference will be much more noticeable. Once you are in an open place and with much more distance, the transition from one image to the other will be less noticeable. Where can these parameters be configured? I've been looking...

    Options for mounting a IPC-Color4K-T180

    @wittaj Is it normal that in the transition from one image to the other there is this step difference? Some time ago I bought the latest Reolink 180° model, and it also had this step and I was not convinced and I returned it, now I see that Dahua also has this step.

    Options for mounting a IPC-Color4K-T180

    Yes, I've read the review of the PDF notes on the official website, and the new features it brings I don't think they don't carry any functionality that would benefit me, and they don't carry any security bugs either, although my cameras are all inside the local network and don't have access to...

    Oh right, I was looking for it by the name of the specific model. :lmao: So nothing, everything is fine. Thank you very much!

    In this case Andy has not published the firmware for the camera I have posted, so I will download the DH from the official website.

    Options for mounting a IPC-Color4K-T180

    So the only difference between the two firmwares on the official website is that in one you have the logo when you start the website, and with the other you don't?

    But is this firmware package suitable for all cameras in general?

    Options for mounting a IPC-Color4K-T180

    Hello, good morning. I'm writing here so as not to open a specific thread, because I don't think it will be necessary. I have just received the IPC-PDW5849-A180-E2-ASTE camera from Andy (the shipment has been very fast to Spain), and I would like to know which firmware to use to update this...

    That is exactly what I was looking for. I think the PDF is more up to date than the Wiki. Thank you very much!

    In search of a Wi-Fi camera

    Hello, good afternoon. I have to buy a Wi-Fi camera, and I was having a look at the Dahua brand ones. Although there are not many to choose from, there are a couple of them that are very similar but one letter changes in the model and I don't know what it refers to (there are also many other...

    Dahua 2MP Starlight Lineup

    I have the camera at home, but I don't want to open it just to find out the sensor model. It was mostly in case there was some kind of list indicating the sensor, but well, it's dispensable. Thank you.

    Dahua 2MP Starlight Lineup

    Is there any way to find out the sensor model of this PTZ85448-HNF-PA camera? I asked Andy, but he told me that the Dahua company doesn't usually give out this information.

    Dahua outdoor camera microphone

    This camera does not use PoE power, its power supply is external and you would have to incorporate an additional power adapter for the microphone. I understand that you could always send power through PoE, but it is probably not good for the camera to have power coming in through PoE and at the...

    Correct sequence for firmware update?

    Please, someone tell the creator of the post which is the sequence to update, or which is the firmware he has to use to update that camera.

    Dahua outdoor camera microphone

    Either you may not have connected the microphone properly, or the microphone you connected (from a PC) was not the right one. This microphone I tested had absolutely thin, almost unmanipulable cables. I don't know if they would be compatible with the three cables that the camera has: audio in...

    WDR vs SSA

    What is the SSA mode? On my PTZ I can't find that mode anywhere, only WDR, BLC and HLC. The third image with SSA mode looks very good.

    Dahua outdoor camera microphone

    Well, I have connected a microphone, and it doesn't work, so I understand that it will have to have its own power supply. I've connected the microphone to the audio in and ground, and I've tried changing the position of the cables in case it wasn't connected properly, and I haven't been able to...

    Iframe interval on Dahua cameras

    But when there is a lot of movement in the scene, I understand that a lower i-frame rate will be better, right? Currently in my cameras I run the same rate of FPS as i-frames, but in one I have a lot of movement in the scene, and I don't know what would be better.
