Hi can anyone tell me what are the manufacturing companies of CCTV and Access control which gives technical support , I mean has their service centre in DUBAI. Please list them if possible, I will be grateful to them if they give us the information on it.

Can anyone give me the basic understanding of Access control, or any material or website would be appreciated. I do not know anything about Access control, How it works, what issues do we get and what are the troubleshooting steps which are needed for that. Thanks and Regards

Hi , Can anyone tell me how to identify a suspect when someone is cutting the video cable of a cctv camera?? It is something related to End of Line concept , Please can anyone explain me in more detail , It would be better if he can explains with suitable diagrams Thanks

Thanks a lot Security sys

Thanks Adam,so what do I suggest the customer, if he wants to use the IR Illuminator in Outdoor Environments to have a better result??

Hi One of the guys is using IR Illuminator of Dedicated Micros and the camera ( Bosch ), He is getting good results in Indoor but not outdoor, could you please tell us the reason for it. Thanks and Regards

The customer says that at night there will be a moonlight, so why not give better results in Outdoor environment while using IR Illuminators ? Is it true, I dont think that there will always be moonlight

First of all, I would like to thanks to everyone for sharing the post, Anymore steps which I need to follow for troubleshooting, Please help me out. Thanks and Regards

In Dedicated Micros DVRs can you explain how to find out ? As you guys told that there will be a signal loss , thats fine but how do the person knows about it , the camera will be placed somewhere else and the feed which is coming from the camera will be to the DVR , How do they know? Can anyone give us the clear answer on this, One important point which you have discussed is to protect a cable with some material so that no one can cut the cable , but in case if he cuts the cable which is being protected then how to find out ?? thanks

If that doesn't happen then just restart the DVR or a camera , Hope it will work fine.

Hi , You can look into the camera webpages if it is an Analogue camera, You will find an option called Flip Image , select that to flip that image. Regards Mujju

Hi can anyone tell me whether we can control the IP PTZ camera when connected only to the network , not to the DVR? Can we control it using the software which will be given by the camera company like , Netvu Observer by DM? or is it necessary to be connected to the DVR?

Can anyone tell me what is Integrated Camera recording in IP camera? What is the purpose of it.......I was told that If the network of the IP camera fails , the Camera still records in its SD memory , Is it so?? or the concept is something different , like If the IP camera is connected to the DVR and if the DVR fails , then the camera starts recording in in its SD card?? which one is true , can anyone explain me in detail? Report this post

Hi , Does anyone has any idea of Multicasting...I have seen an option of Multicasting on one of the DVRs , could you please tell me what is the purpose of it. Thanks and Regards

Hi soundy, Have you ever used this option in your DVRs ? could you please tell me how it works? Do you mean to say , when the camera is sending the packets to the Network , does that mean many people can view the camera from its webpages? or is it something different? Thanks and Regards

Hi Soundy , could you please explain this term in more detail Some can do other in-camera processing, like video analytics.

Hey tom could you be more clear? What do you mean by PTZ controller, the one which would be with arrows on the Netvu Observer?

Also there will be a signal level on the camera itself , to make sure you have the signal level above >=50DB , if not then the video will not be visible to you

I have seen in some of the IP cameras where the resolution would be VGA , so here in the specifications of IP camera , it shows 540 TVL why so , According to my knowledge TVL should come only in Analogue cameras am i right? or the answer is related to VGA , when we are talking about VGA display IP camera, does 540 TVL comes into account????????????? Please clarify

Thanks a lot

Thanks a lot everybody for clearing my doubt

Hi Rory ,Please look at the below concept of ICR, I am getting confused between ICR, IR Illuminators, Day and Night camera( which is IR sensitive ) , One of our customer uses a Bosch camera which is not exactly day and night camera , He has used IR Illuminator ( 64mts , 715nm ) but he is not able to see the video at night ? so what does he needs to do in order to see ICR (Infrared Cut-Filter Removal) works in two ways. On box cameras the the filter sits in front of the CCD module. The filter is rectangular in shape and is split into two parts. One side is IR sensitive the other blocks out IR to achieve the correct colors. It is powered by magnets to switch it on or off. When there is an electric field it will slide the correct side over. This is controlled by the separate ICR chip. The chip is activated by an external CDS sensor. So when it gets dark then the ICR is activated. Its kinda like the ones that turn on the LED's.

Why do we require IR Illuminator? When a True Day and Night camera which is IR sensitive can sense the video at pitch dark condition then what is the need of IR Illuminator? Is this for a longer distance? like in a situation where we require the camera to view certain object at pitch dark condition or something else? Please clarify

Hi Soundy/Jeromephone, Could you please clarify me , How can they do marketting if the IP camera doesn't require to have TV lines on it........Some of the IP cameras will have Analogue Output but that is just to check the ip address and the video would last on the monitor for about 10 minutes , after that the video disappears. So now tell me the clear answer why do TV lines come into picture when talking about IP Cameras? Regards

I am sorry rory , please see my modified message which you got confused
