    Hello Experts,

     

    I am new on here. Usually I try my best to fix my own networking issues but this time I have not been able to and I need guidance.

     

    Modem/wireless router: HG8245H (Huawei)

     

    Wireless router : TL-WR841N (Tp link)

     

    First I would like to say the Huawei is supplied by my Telecom and is not the best device for port forward/rules/ etc. I cannot change that as it is a fibre connection. As far as technical support from telecom, well that is poor service and I cannot change to another provider. so I am stuck.

     

    So that is the reason I got my own TP LINK which is working fine.

     

    I have 2 IP camera. Ycam and Hikvision. Both of them can be access via NO-IP DDNS.

     

    ycam: abcd.com:8150

     

    hikvision: abcde.com:3139

     

    AS you can see from snap 2, the internal host is being forward to my TP LINK IP

     

    Both are working fine can be access remotely. But if I remove the port number, for example abcd.com or abcde.com, I get my Huawei router login page. That scares me.

     

    There is no option to disable remote management login on that Huawei.

     

    Any one who encountered this issue or know a bit more on Huawei modem router ? there are similar threads on here but did not work for me

     

    Thank you everyone

    Did you try this?

    Solution: Disable WAN-side HTTP and Telnet access.

    It is not possible to change the default web administrator's password for the user admin.

    hi all

     

    I'm needing some advice with setting up a Dahua NVR 4104 over a 3g internet connection

     

    so here is my issue, I'm wanting to setup my NVR in my private car garage, the garage has no telephone line or broadband present in the building.

    I'm wanting to remote view the camera from my home, using remote login (ddns).

    now ive setup plenty of Dahua NVR's in the past for people in residential properties, using the DDNS remote login, but obviously the properties had a broadband connection, so my question is this, is it possible to use the NVR over a 3g/4g internet dongle or 3g/4g sim router and if so how and what makes, models and providers are best to use.

    are they able to port forward like a traditional router using 37777/37778 etc..

     

    thanks for your help

    You can use most 3g/4g dongle but most telco have 2 ip, 1 is the WAN IP that you can see and another public IP that is normally share. Only way to view if the telco in your country follow this norm is to use the P2P setting built-in on Dahua newer NVR.

    I am using one Cat5 cable for every 3 cameras of my setup with AHD/TVI baluns each end. So that's 3 cameras per 3 pairs of each cable. The fourth pair of each cable I use to send 24v DC down and then regulate down to 12v DC to feed the 3 cameras.

     

    I know this is not exactly the industry standard way of doing things with CCTV but it did seem to work well...or at least I thought it did until I noticed the interference on some of the cameras..! One group of 3 cameras is a lot worse than the others, and it is the longest run too (approx 80 metres).

     

    I have attached a night-time screenshot, which is when the problem is much more noticeable.

     

    Thanks for your time,

     

    Martin

    Full copper Cat5e? Did you try to remove the other 2 camera in the 1 cat5e 3 camera run and see if a single camera will be better?

    Hi,

    My company has CCTv cameras installed for years with proper placement and we had only little problems.Most security camera stills provide blurred stills and looks like it was shot on 1980’s but good videos are hard to find .Never go for cheaper options always choose a good quality product .An issue for the poor cameras can be the location they are placed in also accumulation of dust can also degrade the images try cleaning your housings .Be cautious while choosing the dealer because some provide old cameras .Always choose advanced home security systems which can provide quality videos .Choose a black and white or colour security camera according to the environment.Use colour cameras only when there is sufficient light and wired systems are the most suited for night vision monitoring as they produce accurate colour imaging.

    I do not agree with you on the bolded part though. Nowadays most decent manufacturer's Infra Red is very well tuned for total darkeness, there is no reason to go for a black & white camera. And if not total darkness, you can in fact have nice color even at night with the new Starlight CMOS from Sony.

    Mine is from China and it is quite reliable. In fact currently many suppliers are clearing their SDI peripherals as many Chinese factories has ceased to produce SDI camera & DVR.

    Did you start to sell EX-SDI?

    Your opinion

    just curios

    Yes just some to an existing customer but I have already given up on SDI completely even though picture quality wise is still the best until 3-5Mp HD Analog is out in full productions with the corresponding spec DVR.

    I found relatively inexpensive 8ch HD/SD 3G SDI over single fiber transmitter receiver kit about 5K from thorbroadcast, most companies change about 10-15K for this equipment.

    did anybody use it ?

    IS it reliable ?

    Don.

    Currently its 3 separate locations and just your typical LED tv, no CPU or ethernet connections.

    Im glad you brought this up, as I had no thought about the future plan to change one of these displays.

     

    1 of these will soon be replaced by a large outdoor LED banner/billboard and ran off a CPU.

    This will be a vertical banner. Using a portion for advertising at the top, then the CCTV broadcast at the bottom.

    This is the primary and most important location for our broadcasting, right at the sidewalk street level.

    So technically, your suggestion would probably be what we will need to do for that location.

     

    For the remaining 2 other locations/tvs, I'm sorry I'm not positive, but believe they are smart tvs, and we could arrange to have LAN/Ethernet cables ran to them.

     

    Im going to have to have my IT team and current CCTV supplier investigate this thread and solutions further.

    I was hoping for a fairly similar and easy set up lie we are running.

     

    Hi Tom..

    I will look into that. Being here in Indonesia the past 7 years, I've lost touch with all the recent advances in products and peripherals the digital networking equipment.

     

    Thanks guys. I was sure there has to be a way, i just wasn't making any head way researching it online myself. I greatly appreciate your assistance.

    Ken

    I think if you still can get SDI DVR it is a better solution, I have done a few installation for Clubs using SDI Speed dome and one of the bigger one in fact using all SDI camera for their surveillance.

    thank you for the suggestions.

    I found a Hybrid DVR with a build in 10" LCD display but under the spec it lists Analog 720P; 960H. It does not list anything about TVL? Will the 1200TVL camera work with it? Would be nice if the camera will list if it is 960H

     

     

    Hi. Please do not buy a dvr with monitor built in .. What is your budget for a dvr

     

    I am welling to spend up to $300 i think for just the DVR I already have a 3TB HD in stock. I did read some of the other posts it seems TVL does not matter when it comes to analog since it is limited to

    NTSC. Sucks I will have to pull all new wires to get digital.

    Most of the HD CCTV System have option to set PAL/NTSC for the DVR & Camera so this is no longer an issue with HD analog. Only traditional SD Analog have this problem.

    Ok, something meaningful, thank you.

     

    1. What size monitor is this from?

    40' LCD TV

    2. Is this a 4x3 or a 16x9 monitor?

    16x9

    3. What resolution are the camera(s)?

    1080p

    4. Which DVR's are they?

    Videopark 1080p real-time for HDMI

    & Half 1080p for the AV

    5. Are there any settings on either DVR that affect PQ or resolution?

    Not on video quality, menu yes.

     

    At first, I didn't see the difference until I took a 2nd look. Not a whole lot based on the size of the displayed attachments.

    Since I snap using a mobile, you won't see much difference but if you view live & compare, you will see a huge difference.

    I already did research a HDMI to composite and the only decent ones are around $80 which is ridiculous, but I was planning on using the HDMI out for local monitor. I also looked into using that mostly useless VGA with a format converter, but the reviews of those were terrible! Poor reliability & poor quality.

     

    Anyone out there that has a DVR that has a composite out that is running HD-TVI (or IP) and at least tried the composite out to a LCD display?

    Here is the comparison between HDMI & AV output on a TVI DVR. Even though it is from 2 different DVR the end results will be much or less the same.

    TVI seems to be the logical way to go, but there are two problems. The four monitors that will be used are all in separate rooms. Way too far for HDMI and that outdated VGA. Why the Chinese insist on using that ancient interface is beyond me.

     

    Anyway, the only solution is to use the existing video cable feeds even thou the image will be analog. Most DVR's do not have a composite out even thou there is a port for it. None of the compact models which is what I would prefer to use have that. The question are;

     

    1. Will the resulting downconverted image be noticeable better in spite of the video format being used?

    2. Will the composite image be anaphoric 16x9 squeezed into a 4x3 that could be stretched or postage stamp (16x9 within a 4x3 with black bars top & bottom)?

    1. If you use HDMI to AV converter you can sent the video to all the 4 TV, quality is still decent. (better than analog)

    Another option will be using HDMI cat5e transmit/receive but you will need to run new cabling. (best quality)

    Thank you Daryl733.

     

    For people who have same question, HLong Asia a seller on this chinese websit said :

    dear customer,

    nvp2440 / 2441 may not as good as nvp2421.

    indeed nvp2440/2441 have more functions on OSD menu, due to SDI camera very bad selling, current new version mostly consider save cost for lower selling price, picture quality may not as good as previously old style version.

    also, image sensor MN34227 will not as good as MN34010.

    best regards

    If you need good quality SDI, I can point you to the biggest and most probably only one left in Shenzhen still doing R&D with SDI camera. FYI, most manufacturer in China has already given up on this format!

    Both are super cheap and will produce similar images today. If you are an installer/dealer I would pick the technology the majors companies are picking. Most are going with HD-TVI.

     

    Out of all of them I believe HD-TVI will be the first to make 4K recorders and accept up to 8MP cameras. 500meter transmission is a plus but I rarely transmit that far. I just purchased 720P HD-TVI bullet camera in metal housing for $24 and 1080P for $35. Most of the cheaper cameras are plastic and that does not work for me.

    Your 1080P TVI for $35 uses what CMOS Sensor? Am testing one with Sony IMX322 & another with Aptina AR0230 and was suprised the AR performs better in low light and the 322 only have a slight edge on image resolution.
