    Okay guys, I am going to give you much more data, so you can help me better.

     

    The budget is not fixed. I have been asked to design a system and I am in early planning phase. If the budget that I provide is too large, they will ask me to cut it or make a new one. There is no risk that I might lose this project. I can check out as many possibilities as I want. This will be my first fully IP system and I want to do everything right.

     

    I have maybe 1 month for the planning and to have an acceptable budget.

     

    The CCTV cameras will be viewed in the local Security office. 4 - 6 screens will be used for viewing. 2 spot screens should be extra and I need a joystick for the PTZ that works well.

     

    I have inspected the property. It is very dark at night. Lighting up the whole area with IR seems overkill, but could be done. With 4 Raymax 300 I could light it up, but the price of this is around 1000 GBP each. Therefore I thought of PTZ that have IR integrated. If you think this is a stupid idea, let me know. I chose 1,3 MP to get better results at night.

     

    4 - 5 PTZ will be outside. Maybe 3 fixed cameras outside and then 10 - 12 domes inside. All inside domes should have IR for the night, so the light can be turned off without loosing the picture. These cameras will show doors, corridors or offices. Nothing large or fancy needed. I thought of 1.3 MP, because it cost only a few bucks more than D1.

     

    I will check if I can find a picture of the property, so you know what I am talking about.

     

    Ahh, cheap stuff, I understand. You have to ask them what software works with it as most software will not be support the cameras directly. Maybe via Onvif, but that's a lowest common denominator interface, it may not work as well as you expect.

     

    Yes, it is rather cheap , but do I get much better performance buying something expensive? Dahua is at least known to me and I have good experience with their analogue products. Hikvision has a camera that looks 100% the same, I would not be surprised if they are build in the same factory. What counts is the end result and the picture that I get on the screen. I think I will check your Blog to see if you have tested some IP PTZ...

    What brand cameras? Will you be using RTSP or ONVIF?

     

    Nothing is better than free. Free requires low tech support when setting it up though.

     

    Well cameras also have to be cost effective. What I will probably get as PTZ is this:

    Others will probably also be from Dahua or Hikvision. I don't know of any free NVR, except Zoneminder. This is not an option though. I am looking for something cost effective, but professional; something that is proven to work.

    Hi all,

     

    I am looking for a cost effective PC Based NVR solution for 16 - 24 cameras. This is for a control room that is manned 24/7.

     

    What I need:

    - multiple monitor support (probably 4)

    - controller with joystick for PTZ control and to control call screens

     

    I thought of Luxriot, but I am not sure if it is good. Has anyone here used it? I also thought of Milestone and Exacq, but I always associate those two with enormous cost. How much do they actually cost?

    Realistically, you only need to cover the narrow entrance to the harbor to ID every ship that leaves, enters the harbor. The only problem maybe a smaller ship hiding behind a larger ship, but that's outside of your control. Maybe have cameras from both sides of the entrance. There has to be electricity at the harbor entrance because there's entrance lights.

    True, I admit.

     

    Raytec's top of the line, the RM300 puts out enough for a 370M beam at 10 degrees. The same illuminator adjusts and can cover 30 degrees at 220M and anywhere in between. You don't need a wider beam because you are watching the ship as it moves in and out, so you don't have to see the entire ship at once.

     

    Then the cameras I suggested before like the ones from Cohu. Also, Mobotix makes very rugged cameras, no moving parts, no NVR or PC needed, like the M12 or D14 DualNight cameras.

     

    If they want to capture images of the ships as they move into docks, there could be cameras and lights at each dock location.

     

    The question really is what he is trying to catch on that recording. Or if someone is actually going to look at this 24/7. In any case, to cover the dock area, he will need LOTS of cameras and LOTS of light if this is not there yet.

     

    It is much simpler to cover only the entrance. I still like the idea of the Thermal camera. Maybe it's no good for recognition of the ships, but I think with 2 - 3 Thermal cameras he could overview the entire area. Ships are large and even if 2 KM away, one could probably see the movements well.

    If you have no light at night and this is what I am assuming here, you will have no picture.

     

    What I can see is that you have 2 choices:

     

    1. Light up this area with floodlights or IR (probably impossible)

    2. Thermal cameras (FLIR)

     

    In any case Megapixel is most probably not going to work at night and Megapixel Thermal cameras don't exist (AFAIK).

    I will (most probably) setup my own network for the cameras. It will be cat6 gigabit standard with maximum 2 switches. There will be 16 - 20 cameras all IP based. Most are D1, but the PTZs and a few others will be 1 - 2 MP. Maybe 5 - 8 will be MP.

     

    I could also try to hook the cameras onto the existing network, which is based 100% on fiber optics. Every office has it's own fiber optic cable going to the server room. I am not planning to put the DVR into the server room though and therefore think it will be easier to biuld my own network. Besides I want to use POE and this isn't going to work with fiber optics cable.

    I have a vast area on the sea(that is a big basin)I wanna use a Megapixel camera to secure this zone but I heard these kind of security camera doesn't work perfectly at night,what's your idea?

    How can is solve my problem?

    may you please introduce me some products and brands?

    all recommendation/advice and Info will be much appreciated in advance.

     

    P.S:I can't use IR lamps because my area is so vast.

     

    You should open a separate thread for your problem. With pictures if possible and some more data like how big the area is, how dark it is at night, your budget, etc.

    Yeah I also found out that it is from Dahua. I thought that I should take the 1,3 MP, because of better visibility at night. Of course the camera has IR, but the area where I will put it is really dark and anything to improve night vision is wanted. If there is no difference other that the amount of pixels I might go with the 2 MP version.

     

    You mean the control is not slow? When I move the joystick on the analogue PTZ that I am used to, it is instant. There is no delay at all. I can follow people and cars (if not moving too fast) with the camera. I was at a Security Exhibition last year and tried a 1080p PTZ from Dallmeier. There was no delay, but when I look at this youtube video I have the feeling that the camera moves 1/2 second after he moves the joystick and I wonder how I am supposed to move the camera precisely with such delays.

    Hi All,

     

    I am planning a job now that is probably going to be fully IP. Outside I will have some PTZ to cover the surroundings. The area around the building is dark in the night. I mean pitch black.

     

    Illuminating the whole area is a little overkill I thought and therefore wanted to go for something like this: http://www.netvisiondvr.com/Home/ProductDetails/166

     

    The price is excellent and the specs look great. My main concern is the control. This camera seems to have no RS-485, so I assume that I have to control it over the IP protocol. The Software from Netvision is certainly able to do that and they even have a 3D joystick to connect to the DVRs. But how is the delay on such systems? Is it possible to follow people with the camera? Does anyone have experience with IP PTZ?

     

    I have seen this video on youtube: http://www.youtube.com/watch?v=uI2kSaa7G20

     

    I was very disappointed in the obvious delay when he controls the PTZ. This is what I don't want. I am used to immediate reaction from analogue PTZ and I would even consider a hybrid system if IP PTZ are not decently controllable.

     

    I am thankful for any input from someone with experience in this.

    Another question I have is that the HikiVision site lists a very small set of Intel-based mother boards in their compatibility list - and I couldn't find any that were still made. I did find a new (old) DP965LT board on Amazon and I suppose I could build a new PC just for this project but I would sure like to build something newer and more powerful - especially for running W7 X64 on.

     

    Usually there is no problem using newer mother boards. These are the tested-and-guarateed-to-work boards. I have always ignored these recommendations and bought whatever mother board I wanted.

     

    Only once I had a problem with a mother board that didn't seem to like the DVR card, but on this install it turned out that using another HDD for the OS handled the problem.

    The Base station has 35 Watts output.

     

    I honestly never understood the Ohm value on coax cable. What is it for? Why do I need 50 Ohm cable?

     

    What type of cable is rf cable?

     

    Hardline looks okay, but I have never seen it in Europe. Must google some more... its really expensive though.

    Hi guys,

     

    Well, this didn't fit anywhere so I decided to put it here.

     

    I have to install a Motorola MC2100 UHF Base Station. The UHF antenna exists already on the roof. The Base Station is in an office in the Basement. What cable do I use to connect the two?

     

    I have seen RG59, RG6 and RG213 being used for that. The distance from the Basement to the roof is large (50 - 60m). What cable is best for that?

     

    Thanks!

    I am looking for a good PTZ camera for day and night.

     

    I only have personal experience with the GE/Kalatel Cyberdome and a Samsung PTZ from 2-3 years ago (Don't know the exact model).

     

    The location where the PTZ is supposed to go is a well lit Street in the city. Between 4-5 AM it is really dark, because Street lights are turned off.

     

    The CyberDome was the first PTZ in that spot and the quality was good. Sometimes it was hard to see in shadows when the sun was shining. Everything in the shadow had very little contrast.The Samsung (now in that spot) is better at that. I think it has WDR, BUT the Samsung really sucks at low light. It can give a good picture, but the auto focus takes forever to get a decent focus - sometimes it doesn't get a good focus at all.

     

    Now I would like to know PTZ that:

    - work well in low light

    - have a good and FAST auto focus that also works in low light

    - have WDR

    - have Kalatel or Pelco D protocol

    You need to use your ISP's SMTP Server.

    The ISP is the company you use to get on the internet.

    The port should be 25 by default.

    Email should then work.

     

    I thought we covered this?

     

    That's right, you have been very helpful, but nothing seems to work and as someone stated "it's probably bad software" and I can't find other software that will work with my DVR capture card, so I have no choice but to try another route, problem is I have spent money on hardware that I would like to use. As for the ISP I have my email setup and working through them if I use Outlook Express, and I have carried all the information to IDVR4000 to no avail.

     

    Thank you very much, your patience is to be commended.

     

    God bless you

    Jim

     

     

    But have you actually gotten your ISP's SMTP and tried it with that one?

    This is not a downside of baluns so much as it is a downside of cheap 12V cameras that have a shared power and video ground. Use dual-voltage or AC-only cameras (in other words, something with an internal regulator that separates the video and power grounds), and you don't have this problem, regardless of whether you use 12VDC or 24VAC.

     

    True, but it is also true that it doesn't happen when you use coax instead. In my experiance also brand cameras use a common ground sometimes, especially IR cameras and dome cameras.

     

    I prefer to use separate PSU instead of limiting myself to cameras that have dual voltage.

  25. Posted

    Should keep coax at least 1 feet from high voltage, so yes interference is a concern.

    BTW 1500' would be RG6, 1800' with RG11 (depends on the brand of cable).

    RG59 is less, maybe 750?

     

    BTW at those kind of distances, its a better idea to just run a big multipair and then branch of from that with coax or cat5. Then you have extra cables left over incase they want to add more cameras later. I would amplify any cable over 750' anyway, and keep all cables away from high voltage.

     

    Yeah, I didn't really have that choice of keeping it away from the other cables in that Warehouse. It went well though and there was no loss in picture quality. What do you use to amplify the camera signal?
