    Some counterfeit makers are supplying their cameras to HikVision or Dahua.

    SunnyKim, I don't understand this statement. These two companies are buying counterfeits of their own cameras?

    These two have become already big. They do designs (research & developements) with several design houses, out side. They own legally their designs, but no longer carrying assembly line for most models so that they can get more profits. Local manufactures are running assembly line and supplying to them under OEM/ODM, leaking the copies to gray market.

    Nowdays most of IP cameras are using the two kinds of chipsets. To be specific, chipset from TI (USA) or HiSilicon(China). The video quality is determined by their SDKs. The quality parameters are finely tuned and stable. Therefore, we can say the video quality are on the same level, not much differentiable.

    IP Cameras from HikVision or Dahua are good and recommended a lot in this forum. But if you do not receive any Tech supports from them, why pay more??? There are many kinds counterfeits at much lower price. Some counterfeit makers are supplying their cameras to HikVision or Dahua. There are many other small suppliers, as well, who are confident to compete with a lot better Tech Supports. Any one recommended from your Local CCTV installers could be OK as long as you can get Tech Support when needed.

    Video Decoding Channels:

    5MP: 2-ch;

    1080P: 4-ch;

    720P: 8-ch;

    4CIF: 16-ch

     

    It will NOT decode 6 1080p channels. If you want 8ch 1080p decoding, you might go for 6404 model.

    Can you please inform me of the price range of DS-6404?

    I checked out amazon and aliexpress. It is way too expensive. Unreal???That's why I am asking.

    If the cameras are all analog, either NTSC or PAL, your problem could be solved easily.

     

    Idea One : The distance, Max 120 meter, can not be an issue.

    You do not need any amplifier, or that kind. You may make a Signal Splitter(simply passive), T Splitter, One Input/ Two outputs for each camera output.

     

    Idea Two: Buy two DVRs, costing less than U$ 50 in total. Use its CVBS output to the input of another DVR for a remote monitor.

    Remote Viewing video over internet and on smart phone is By Default.

    Letting alone analog camera and IP camera, there is another kind; HD video in analog fashion: It includes 3 types. Check out HD-CVI, HD-TVI, and HD-AHD. Their video resolution is better than the conventional analog camera system. The cost is as good as Analog system's. Say, 4Ch X 720P system can cost much less than U$300, including HDD and a standalone DVR. If you go for analog systems, say 4Ch X D1 or 960H, you can get it done around U$200, including HDD and a standalone DVR.

     

    Thanks Sonny! I had no idea about the different types. Question though: What does the D1 stand for in your last example?

    Also, are those types equal or better in severe weather? I live in the Chicago area and we get hit hard with snow and wind. Sometimes the snow blows straight sideways or swirls up.

     

    Analog Cameras are Very Very Cheap and have been there, Tough & Rugged. If you buy a DVR with recording resolution D1 or 960H, the video quality is OK, not as bad as being trashed by peddlers of IP cameras.

    I don't need to play back 64 channel. I just need to have a live view on monitor with 64 channel main stream. Possible to do so?

    I now got to know that You mean Mainstream for Live Spot Play.

    The cheapest solution that I can come up with:

    Let each DVR CVBS (TV) out. So you may have 4 CVBS analog outputs for 4 of your current DVRs. You may buy a 4 Ch analog DVR, costing less than U$30, then let it output the video to VGA or HDMI port for plugging to your TV or monitor.

    No experiences wth these cameras, but I guess it is to blame camera setting. Check Out their default setting. Check out I Frame Interval and P Frame Interval are set correctly. Check out option for Rate Control.

     

     

    If this were the problem why would it work just fine through the web browser and not via the recording software?

     

    We are talking only 2 Cameras and Softwares of branded, somewhat. My only guess left is to blame camera settings that probably changed from the original default setting.

    So far, at the top of my list is:

     

    1. HikVision 4MP WDR Vari-Focal Bullet IP Security Camera 2.8-12mm (Model: 2CD2642FWD-I)

    2. HikVision 7716NI-SP/16 16 Channel POE Plug N Play Hi Def NVR Recorder

     

    Any thoughts?

    When you go for IP camera system, please read the today's thread

    viewtopic.php?f=12&t=47989.

    4MP IP Cameras? Wow that may cause a lot compelxity to Playback/Saving.

    I may recommend 720P IP, if you are confident with IP system.

    You may go for HD-Analog systems (720P is good enough)-HD-AHD/HD-CVI/HD-TVI, for your home application.

    Boogieman dancing around in this forum could answer your problems. I do not understand why so many advocates IP cameras. Some keeps peddling 4MP cameras from HikVision. There are still problems with "3 IP Cameras with each less 3mbps and less 10 FPS".

    You dont know what you are talking about. This is a network related issue. Thousands of other people dont have this issue. Why dont I have this problem? One post and sunnykim pops his china scammer head up out of the sand. Fool. Search this forum for thousands of problems with analog. Do you blame analog or the installer? We are not dumb here in america. You cannot scam us anymore. We have youtube!!!! We can see the difference between D1 and 4mp. Fool. Time to take some networking classes sunnykim.

    Go back to your china assembly line and keep making your D1 low resolution garbage that your company dumps on unsuspecting fools.

     

    His answer is simply to blame your network bandwidth, not to blame the system of IP Camera.

    Hi,

     

    Ages and ages ago i had a really old CCTV camera and it was awesome in the dark, I'm probs going back 10 years or so ago, but now they would seem that they all come with IR's etc.

     

    I bought a few of them claiming that they see well in the dark (without IR as the cams are viewing through a window) so thought I'd try a few that claimed they were good in the dark, well not complete darkness as my car is under a street light which only points down from the light as it's an LED street light outside. so not one of them horrible yellow glowing ones.

     

    But all the camera's that I've tried are a waste of time. nothing as compared to that old CCTV cam I had and that didn't even have IR's on it, was just awesome in both day and night time....

     

    So, what I'm looking for if you guys can help is a camera that I can mount covertly in my house pointing out the window to my car. My car is parked across the street you see so I don't want it blatent that I have a camera pointed in case on of the people over the road kinda think it's weird etc. and panic that I'm watching them.

     

    I've seen quite a good CCTV kits for recording etc. but can come back to that, a great camera would be a good start for me.

     

    Thanks in advance.

     

    Well, The old camera that you like must be analog and its sensor could be old CCD. The CCD sensor is getting out of production/market as it can not compete against cheap CMOS based sensors. Keep using it till it dies away. Meanwhile hopefully CMOS HD cameras will find its improvement on its low light performance. The second choice could be using 720P HD Cameras, now very cheap. You must know that the CMOS sensors used for 720P camera are the very same sensor for 16 MP cameras. All of these are related to inferior low light performace of CMOS sensor.

    We just wanted to feed the video from the camera straight to the projector.

     

    We don't want to a DVR and we have already have a software controller for the PTZ.

     

    Within my limited knowledge,

    the HD-SDI format for the raw -video output from HD-SDI cameras is not in HDMI format. Both are different. You need a receiver to convert HD-SDI format into RGB video format then RGB to HDMI. It can be done by HD-SDI DVRs with HDMI output capable.

    If nobody puts comments for a given time, you better prove HD-TVI system yourself. One camera, one DVR, and the max cable length(cable roll) would not cost you much.

     

    So far we been installing HD-TVI systems here and got great results, in fact better than IP since there limitation (300ft max before adding another switch.) when it comes to cost to our clients. (Fiber expensive here).

     

     

    The farthest we ever run on UTP (CAT6e) was about 800 ft (244m) using HD-TVI Baluns and approx 900 ft (275m) on RG6.

    We know that HD-TVI is capable over 1300 feet, just trying to figure out if there are coaxial cables we can get without splicing, or has anyone ever tried splicing coaxial for HD-TVI?

    Thanks

     

    Good to know to hear success of HD-TVI in field

    Too bad to know there are some guys who keep peddling 4MP IP Cameras even for home applications or ministores.

     

    Google and Contact "TechPoint" and ask the company about choosing a good quality cable for a longer distance. The Techpoint develops chipset for HD-TVI. They should know !!!.

    The video information captured at analog camera is carried under the format of NTSC or PAL TV Signal. The TV Signal is limted up to about Max 3 Mega Hertz, very small. The OLD DVD/ VCR Player generates the same TV signal. You may have liked its visual quality. Even the information of 480 TVL can not be fully contained by 3Mhz bandwidth. In other words, I mean 480 TVL is good enough. 700 TVL could be better just because they are new and techwise, most likely, more advanced from 480 TVL. The 700 TVL could be cheaper than 480TVL. But we can not be sure always TRUE. So if you do not like the quality, you can return it. One thing for sure is that 720P-HDCVI/HDTVI/AHD cameras are better in theory, than new 960H analog camera, if the cable length is not that long, say 100 Meter.
