Hi none are fit for cctv and none are coax you need 75ohm cable for cctv (coax) both your links are 100ohm The lead kit you posted will work but only on short distance ... not the length you need can you not buy cat5 and use baluns ... cat5 is also 100ohm but by using baluns at both ends makes it 75ohm and the rest of the pairs are used for power

Link to new cable I bought today is https://www.amazon.in/Video-Power-Connector-Security-Camera/dp/B074DWRLZF/ The current cable installed is https://www.amazon.in/ZEBRONICS-Copper-Wire-Roller-Network/dp/B07FMW2W9P/ As of now, the camera is working fine, but not sure for how long. Last night after I created this thread, it worked for 5 hours straight without a glitch and then for 1.5 hrs wavy picture. Then went back to normal itself for 1 hour and then wavy. I have a reason to believe Camera (clear image), DVR (no errors, also updated firmware), and Power Adaptor (no fluctuating lines, tried 12v 2amp also) are fine. It's not the case of loose BNC connectors as I changed them already. I am doubtful about the cable but when it works, it works as new. Replacing the cable is a tedious job as it runs down two floors to the basement parking!

I recently purchased an Interlogix TruVision TVR-15HD DVR. I am using TruVision Navigator 8 as the client software. Is anyone else using this? In my application, I use the wired alarm inputs, which trigger a higher quality of recording on specified cameras and insert an alert in the log. The most important feature to me is to be able to search the log for alarms over a given period of time, click on one, and have the video from that camera start playing at that point in time. Navigator has that feature, but it works unreliably. It's invoked by right-clicking on the DVR device on the left panel and selecting "Search", and then specifying some parameters. It finds the alarms okay, and when clicked the video from that camera starts playing. But it starts playing at the correct place only about half the time. Otherwise, it picks a random time, usually but not always in the same day. Occasionally the random time is an exact number of hours away from the correct time, but this could be coincidence. It also starts at the wrong place, sometimes, when clicking in the timeline or entering a date and time manually. Anybody? If it makes any difference: * I have twelve analog cameras on a sixteen-channel unit. * I've set up the unit to increase frame rate and image quality for the fifteen seconds before and sixty seconds after the time of the alarm. * I cannot see any pattern to when it works and doesn't. Thanks. -- Derry (If you're interested, I purchased this unit because it has a feature helpful for me in integrating it into my other home systems: It supports using the IR remote control to select the contents of the main monitor and the spot monitor individually. No other units seemed to have this.)

Can you post a link to your coax cable
-
You can not look for a professional who will work for you all the time - you can turn to a special service one-time. Such service as one that can rewrite my essay www.papersowl.com will help you with the implementation of these items. Some professionals will be able to work on your assignment at the same time and this will entail the fastest execution of the assignment.

I do have a spare camera but not the cable to try. I have ordered one 60 feet coaxial cable from Amazon. The current cable is just 2 years old and does not seem to have any breaks.
-
Thanks for the reply. I tried another new adaptor but same issue. Is the coaxial cable faulty?

LTS coax DVR talking to VISCA protocol camera
g.beauw posted a topic in General Analog CCTV Discussion
I just upgraded the ancient DVR in my coax based system and installed the LTS DVR LTD8516K-ST (coax type) so I beginning installing HD-TVI based cameras without having to re-pull all coax wiring. So far the DVR seems to work well with the LTS cameras and I can get the DVR to talk to the LTS Cameras using the Coaxitron(Default) PTZ protocol and bring up the camera configuration menus remotely. However, the DVR doesn't seem to speak to my SPECO HLPR67T LPR cameras so I can call up the Menus vs. climbing a tall ladder to manually tweak settings at the camera. The SPECO TS guys tells me that their DVR is set to speak the PELCO-C protocol to the HLPR67T which is set for the VISCA protocol at 9600 baud. The LTS LTD8516K-ST DVR doesn't seem to have either the VISCA protocol or the PELCO-C protocols listed as a PTZ protocol. The DVR has lots of protocols available (many of which are variations of the PELCO-D and PELCO-P protocol), but it seems the SPECO camera won't do those PELCO-D/P protocols. Given that the SPECO TS guy doesn't know why the HLPR67T won't work with the PELCO-D or PELCO-C protocols nor can he explain any details about the compatibility between the PELCO-C and VISCA protocols (which is the combo he has to use), I have no idea what would work here. I'm waiting to hear back from LTS TS to see what they have to say -- maybe a new version of code for the DVR firmware that has PELCO-C or VISCA -- or some guidance as to what protocol in their long list to pick and configure to get it to work with the SPECO camera when it is set in VISCA mode. Has anyone run into this and have any suggestions? -

Couldn't you just run a cable from DVR monitor output to TV direct -
Have you tried a different camera that looks like many cable fault in honestly could be a slight short between dialectic and shield

Thanks for the reply. Yes, it's happening with all 4 BNC inputs. As soon I connect to a different BNC port, for 10 seconds its fine and then back to Wavy picture. Is the DVR faulty?
-
I tried using what You advised me. Problem not solved
-
Switch the camera to a different bnc input and verify whether it's still doing that
-
Hi Tom, Tried that, it works fine but we still can't access the system as no-one can remember the password. Any ideas on a master reset password or something of that ilk? Many thanks, Atlas

Dear Forum Firstly, kindly excuse any naïve questions or such, I am new to this forum and setting up security systems. As a background I am currently renovating a residential home and would like to install a CCTV system. At present, walls are largely open on the inside of the building, giving good access for cabling and such. This is why I would at this stage like to plan and install the needed cabling, so that at the very least, the pre-wiring for the installation of cameras and outside lighting is in place prior to completion of the refurbishment. The property is surrounded by a fence, but it is low and could be climbed (about 1m tall). However, except for the street side, any access to the property would have to cross a neighbouring property. In this regards I have a couple of questions which a more experienced designer might be able to answer easily: How would you in principle install the cameras? On the corners of the building or otherwise? Fixed view cameras or rather a combination with PTZ cameras? Once the camera locations have been established, does a single CAT6 cable to each location suffice? (assuming one uses POE hardware) Do the cables each need a “home run”, or can one also use switches / other hardware to reduce the number of wires coming back to the DVR? (assuming that POE switches / hardware is used) Any advice as to what cameras / system to choose is of course also welcome. I would be very grateful for any advice regarding the specific project in mind. I attach a couple of drawings which show the situation of the house, alongside drawings of the facades, which should help establish where to put the cameras / lights. There is a fair bit of street light at the front of the house, but the garden is rather dark. I look forward to hearing your views on the above. Kind regards, RD

Hey, I have a CP PLUS Dome indoor camera (CVI, PAL) 2.4MP connected to DVR via Coaxial/BNC cable which has been working fine for the last 2 years. All of sudden, I have started getting black wavy lines on the screen as shown in the picture intermittently. Please note that as soon I disconnect the power from the camera and reconnect, everything goes back to normal immediately. However, after 20 seconds (sometimes 10 minutes), it goes back to the wavy picture. I already tried changing the power adaptor with the same results. The camera is not connected to any metal objects. Anyone can suggest what exactly is the issue? Thank you.

My dahua xvr 5816s with build date 08/08/2017 is working very fine.i can ping my IP and gateway successfully.the internet connection is stable. My smart pss is showing "ofline(timeout) status" each time I run the program,it takes more than 30 minutes to show "online status".the desktop i installed my smart pss has stable internet connection.i have tried all I could to stop this delay of coming online or showing offline(timeout).I install the latest PSS. Please anyone with possible solution to this problem and also,can you please tell me the cause of this delay in coming online or why it shows offline(timeout) for some minutes before coming online. Your response is highly appreciated Thanks

I want to upgrade my system but I have recently run new Coax all over.
osity replied to osity's topic in DVR Cards and Software - PC Based Systems
I appreciate the feedback. Since you have not provided any requested links to cheaper encoders which that you mention or any alternatives to a quality, fully functional VMS, I'm going to assume the $400 CAD with IP cameras option is my least stressful path at this point and really not that much money at all considering those encoders will also cost money. IP seems to be the way of the future. -
The DVR now has a red light on the 'net' led. I can only access the cameras over the internet infrequently. Sometimes I can view on my phone but other times it reports that it failed to connect. Is the DVR dying?

jeromephone replied to martynball's topic in Video Transmission/Control Devices
I would use a powered 1 in two out splitter to send the same signal to the dvr and tv guessing the tv would have the correct input. units are not that much money and you could power them from the tv or dvr location -
Can't go 900 ft. with twisted pair Ethernet without powered repeaters. Max is 100 meters (328 ft.). And even that may be pushing your luck with PoE, depending upon the load.
-
i need someone recommendation need to run IP Camera up to 900ft with POE injectors my question what cable is better to use cat6 or cat5e 40ft will be barrier under the groun with pvc in the rest over the fence inside of PVC pipe. another question is do i need to use shield or unshielded cable
-
I installed a Samsung 4K security system. On some of the cameras I am using 25ft and 10ft extensions connected to a 15 meter cable. When using these cables I lose the signal. When I connect two 15 meter cables together I do not lose the signal. The wire gauge on the 15 meter cable is larger than on the 10ft and 15ft cables. I assume this is the cause of the loss of the signal. Problem is I can not find 10ft and 15ft cable that has the thicker gauge. Please note that all these cables are advertised as HD cable. Does anyone know where I can buy thicker gauge cable?
