if your system allows the tvs to select the source you are providing (the dvr playing whatever your going to display)then it would work fine, if not you would need some way of introducing the signal onto the existing cable so the tv;s can tune into it- that's a more difficult thing to do and beyond my expertise.

see:- http://www.cctv-information.co.uk/i/Understanding_Infra_Red_Lamps 950nm invisible to human eye. you could light the area up with one or two of these and fit a camera that is sensitive enough - don't know how covert it would be, the ir does not need to be right next to the camera, as long as the camera is pointing to the invisible "ir lit area" if that makes sense.

so you are saying that the balun works ok on another camera- no pink when used on the other cameras so balun is ok. So problem must be with the cable or the camera- can you check if the picture is ok at the camera before going onto the balun- sometimes the auto white balance needs to be reset- if it drifts you can get funny colour reproduction. can you try the camera next to the dvr with a short length of cable to prove camera and balun are good- then that just leaves the cable.

Struggling with SWNHD-820CAM / please help.
jazzar replied to kelso's topic in Installation Help and Accessories
Glad to help. wireshark is very useful for this kind of problem. I don't have much experience on the software viewers. -
similar model here probably yours will be same- contact via their web page if your not sure. see page 49. http://pro.sony.com/bbsc/assetDownloadController/FCB-EX11D_Technical_Manual.pdf?path=Asset Hierarchy$Professional$SEL-yf-generic-153703$SEL-yf-generic-153738SEL-asset-116851.pdf&id=StepID$SEL-asset-116851$original&dimension=original

confused - sending a DVI signal from on place to another
jazzar replied to Lindopski's topic in General Digital Discussion
quick google found this:- http://www.lindy.co.uk/audio-video-c2/extenders-c181/dvi-c183/dvi-display-over-gigabit-adapter-with-audio-p6773 never done what your wanting but the above seems to tick the box with AUDIO too- you can talk to them aswell - if its a benefit ? -
so you can connect fine to another dvr and get the web login page then login to it no bother. In the past when I have come across web issues like buttons missing etc it has been to do with the browser settings affecting access to scripts and running components etc under the custom security button on internet explorer. on ie11 most are disabled. It seems to block certain parts of the web page from loading. you could try running wireshark Ethernet logging program and see if it gives you any pointers.

try Nortek they did a cat5 version as well as the analogue bnc last time I checked.

Giant portable battery with AC adapter input/output
jazzar replied to friendfoe29's topic in General Digital Discussion
you could get a second battery fitted in the boot and wire your gear to that one and have a PROPER AUTOELECTRICIAN put it together with proper fuses etc and wire up a crossover switch which will cut the connection to your main car battery thus the boot battery is the only one that will drain. then when driving flip the crossover switch to allow it to recharge. -
Molynx CCTV system Help required
jazzar replied to dannyboy147's topic in General Digital Discussion
think you need to get into programming mode and map the camera title/ decription to the actual physical input channel on the visilynx controller. ie you can have physical input 1 and name it camera 6 oand physical input 2 and name it camear 8 etc. it allows you to map the cameras in the order that you want instead of having to physicaly swap all the bncs at the input of the controller. I may have a copy somewhere of the programming sequence- let me know how you go before I start trawling for it. think you need a password to get into programming menus- would you have one ? -
Hi- simplified info: http://www.vdtsi.com/indigo/5.pdf Deep info:- http://www.cisco.com/c/dam/en/us/td/docs/solutions/Enterprise/Video/Stream_Manager_Video_Surveillance_SRND.pdf Happy reading.

usually when this happens the laptop needs some kind of activex component to allow the video stream to be viewed. generally when you run the viewing app and select the camera a message box would come up saying that a component is required to be installed and it would normally pull it off the connected camera. you could try the web page of the camera manufacturer to see if it can be downloaded and installed on your laptop. some issues also present using windows 7- try an xp machine if using win7 or win8.

have you tried swapping baluns around- does pink picture move with the balun- if so -faulty balun.

Struggling with SWNHD-820CAM / please help.
jazzar replied to kelso's topic in Installation Help and Accessories
Not sure if you need a cross over cable when connecting direct to the camera without the router. the new ip kit autodetects and will establish comms anyway. - the older ones may need a crossover cable - you could try crossover cable. Anyway if you put the system together when you were able to see the 192.0.0.64 via the router and you can ping it then try running wireshark while you power up the camera and see if you can see a BROADCAST from 192.0.0.64 and see if you can find the gateway, if you find the gateway try putting this into your laptops settings- then try connecting with web browser. You could also do arp -a instead of ping this will give you the 6 double digit codes along side 192.0.0.64, the first three sets are the manufacturer code, the next 3 sets are the exact device. Google the codes and you should identify the make and model of the camera. if 192.0.0.64 is the camera and its not showing up messages on wireshark then something is wrong-- you should see source info from 192.0.0.64 and also destination to 192.0.0.64 even if you don't get to connect on the web browser you should still see info to and from the device if its communicating but denying you access. Any messages would be better explained by a network chappy- I am not to up on it. -
Installing DVR with BNC cameras to access remotely?
jazzar replied to seriousfew's topic in Installation Help and Accessories
Standard bnc inputs only provide a basic standard composite tv video signal. the IP network cameras scan the image and produce digital data that can be sent to any device that it connects to. the quality can range from hd to megapixel types (2meg is equivalent of about 5 cameras)- 35meg used at football grounds and they can zoom in on a face from across the opposite end of the stadium from 300m You don't need all the cables from ip cameras to come back on individual cables to the recording point. 1 cable can run from the dvr to a switch then one cable from this switch can be run to the next switch and so on then each switch can have multiple cameras attached so all camera data will run down the main cable linking both switches together. Also anyone who connects to the network can view the cameras you don't need to run coax cables to every monitoring position. Result is a CCTV system can be installed on existing data cabling providing it can handle the high data rates of streaming video and anyone with the software on their pc can access the images. see;- http://www.jansenelectronics.net/shoppingcart/pages/Analog-Vs.-Megapixel-IP-Cameras.html for more info -
Struggling with SWNHD-820CAM / please help.
jazzar replied to kelso's topic in Installation Help and Accessories
HI if 192.0.0.64 is your camera ip address you may need to put in the gateway as well- I had trouble with this scenario before - when I entered the gateway it loaded up in the web browser- also had windows 7 fail to run the web connection but on xp it loaded fine. -

jazzar replied to kelso's topic in Installation Help and Accessories
so you still don't know for sure the Ip address of the camera- it could have been changed - is this right ? if so. to find the ip address you can download wireshark- free Ethernet logging program, running this will capture all the data packets between your laptop/pc and the camera. by running the program and the n powering up the camera you should see lots of data lines, you want to look for a BROADCAST followed by an IP address and a gateway. This is the camera asking for info on what its connected to so you may see something like BROADCAST who has 10.10.10.1 tell tell 10.10.10.50 the .1 is the gateway and the .50 is the device so 10.10.10.50 would be the camera and its gateway for communicating is 10.10.10.1 see: for a guy doing this to find ip address of camera. You will now know for sure its IP address and can then set your laptop to the same range and then hopefully connect to the camera. -
4 Channel Active UTP Balun Help
jazzar replied to boss_es's topic in Video Transmission/Control Devices
I have always used addlestone kit for long distance- they usually have adjustments to compensate for high frequency loss and mid frequency loss which suffer over long distance, these adjustments allow you to reconstruct the signal. they are in the uk and have always been good on support. take a look at video launch amplifiers on their web page and also the new product on this link:- http://www.addlestone-electronics.co.uk/new_products.html give them a call they are very helpful. I wouldn't trust 2400m claim from a company at the other end of the world- my opinion. at those distances it could be worth putting in fibre- no video loss at all they do an 8 channel over 1 fibre. -
its probably windows 7 or 8 that is the problem viewing video- try running laptop in xp mode if you can or try an xp laptop. the nvr should be recording/playing fine. in ie11 you can click on the cog-tools icon on top right and select f12 tools this allows you to set up older style browsers and windows operation modes for internet explorer- not 100% up on it but you could investigate with these. there are also all sorts of active x components in windows 7 that are disabled- they may need to be enabled. Its a nightmare the number of settings that can be tweeked.

you need a codec- basically a unit that will change the bnc signal to an ip signal and transmit it across cat5. the codec will have an ip address and you will use that to connect / record the video from your camera. you will need a codec for each camera. google cctv codec and take your pick.
-
they are really good cameras - but need a little light ( all cameras do )- they will drop into black and white mode when light level drops too low so you will lose colour -in case this is important. you can over ride this to give you colour in the dark but the picture will be more grainy.

Samsung NVR - iPolis cennecting trouble
jazzar replied to imran.naseer's topic in Computers/Networking
I recently found issues trying to connect to samsungs older model cameras using windows 7- it didn't like it - wouldn't connect via web browser but worked ok using Samsung live viewer, I then tried windows xp to connect via web browser- and it connected straight away. maybe this will help . -
have you tried this:- http://www.ntic.com.tw/S-OnLine.asp?lg=en contact manufacturer.
-
do a search for video mule - 4 video down 1 co-ax. or if you use ip cameras you could run cat5 and use a network switch that provides power down the cable- (POE switch - power over Ethernet) limited to 100m total distance.
-
is this manual any good- look at hard drive info around page 59. http://www.mitsubishi-photo.cz/czech/hlavni/security/videa_time_lapse/dx_tl2500e/DX-TL2500E_User_MANUAL_s.pdf
