THANX. I got it. Now I am viewing on windows 7. Here it is what I did for all my friends facing similar problem. Tools --> internet option --> Security -->Trusted Sites --> Click --> All zones to default level -->. close the dialogue box, open the browser, type the IP (internet explorer). Allow to install Active-X and plug-ins when popup bar appears. Will take few seconds. VIDEO IS THERE. Thanks again for reminding me.

Hello Dear friends, can any one advice, My DVR working properly on Windows XP but not with Windows 7. The player appears on the screen without video . True advice will be highly appreciated.

Hi every one, I have a project where almost 18 cameras are to be installed .9 of them are speed domes and rest are static, for each camera 3to 4 kilometers of cable will be recquired (from camera to Dvr). It is not possible to put any line amplifier in between the cables to boost the signals. Which cables will be suitable for such lengths, (video cable, cable for PTZ keyboard cotroller,and power cable 12v dc.)Suggestions will be highly appreciated.

Thanks everybody for suggestiions, can anyone give me the link for NTV

Thanks for advice, but as far as wireless is concern, is there any system that can manage 43 cameras at the same time and can control ptz.

Sorry Guys for a very late reply, as I was busy in the same project.I was asked to do as many visits and develop a system. Now the actual position is, there are 43 cameras to be installed, out of which 23 are speed domes of various zooms, 10 static and 10 panning. The length is less than 3KM, It is difficult to put a line amp in between cables, is RG11 suitable for video and cat 6 as ptz controller cable.

Sorry guys for late reply as I was out of the country for a project. The approximate distance of cable from the camera to dvr is bitween 2 to 3 kilometers.

Thanks for the suggession, I don't think I'll be able to get jell filled cat5e cable,and 900Mhz transciever from the market, if I use cat6 cable for both will it work.

You must have few things in mind when you talk about IR camera,(1) the covering angle of IR lights is never the same as that of lense,it mostly covers the centre part of the screen,the left out area will be snowy or grainy. (2) No. of IR lights and how much powerful they are.(3) IR cameras are not EX-VIEW cameras. If you stood in front of the camera to adjust it, definately the picture will be clear.

Hello Fllows, I want to install under vehical inspection system.If i use IR cameras will they last as much as they do in normal position. As this unit will be installed underground with no shade above and the lense will be exposed to direct sunlight. Any other camera for this requirement please advice. Thanks. S.I.Sodagar

Once such thing happened in one of my installation, I checked each and every thing, and found them perfect, then I removed the BNC connector of that perticular camera from the DVR end and pluged in after a few seconds, while the supply of the camera was on, the picture was back to normal again. Try this !!

Soldering protects the connections,as the bare copper oxidises and the contacts will not remain fast in long term.

Iam using twist ons and soldring type, both of them are perfect.

Use an active video splitter to distribute the video signal of the camera to your two televisions in the A/V mode,this will give a good quality picture. And there is no need to run a new RG59U cable.Using a BNC T will reduce the quality of the picture.

Seems to be a cable problem,use another testing cable of good quality , and check the result,and also check the cameras directly to the monitor.If the problem is still there then the out put signal of the camera is not good enough to reach the recorder.

VHS systems are slowly going out of the market, using a 6hrs tape is not good as the tape is so thin that it will not last for long. If your recorder has a feature of long play, then continue with a 3hrs tape that will give 6hrs of recording. If not you can buy another recorder with long play feature,its a cheeper solution as compared to the DVR.

Hi Karen, I have gone through the whole story, the best way to put a joint due to any reason , is to splice the cables , twist the centre conductors and the braid (seperately), and solder them. After that insulate them properly,to protect the connections from moisture. I don't how many times I have done so ,on very long lengths as well. This thing is all right for CCTV video signals, and not with the RF signals because on each joint you loose 3dB.

I have a Stand alone DVR Naming X-VISION. it has real time display and record speed of 50 fps. Did any body know its actual manufacturer? i only know that this DVR is made in korea. I am facing a problem in this unit, when i connect the lan cable it gives a flash of light on lan port and doesnt make connection to the network. i have also checked the cable and its fine. but when i connect the second unit it works perfectly on to the same cable. kindly helpme.

Thanks rory, The topics were very interesting and informative. S.I.Sodagar.

Hello Fllows, Can any one advise , what is the difference between WDR Ex-view and normal Ex-view C-Mount camera with same good specs. placed out door with same lense.(which one will give sharper image and more details.)

Thanks for the information, if the no. of pixles are 410k or 470k, will it be good enough. Actually the demand of my customer is that the camera should be color, of 500 tvl , WDR, day and night and with image masking feature. is there any manufacturer in Tiwan or in Korea kindly recomend. Thanks, S.I.Sodagar.

Actually the main problem is with the sun light, the place where the system will be installed is open with no shade , its in open sky facing East and West. The sun light will hit directly to lense for some time every day , in such a condition, how long the CCD will last.

I agree with kensplace, are you using the same cable as in other cameras ?. If yes then check the connectors the contacts of BNC male, female will be very poor.

you can go up to 2.4 km using smart device (for color camera)

Thanks, that will help me a lot
