Cheapest way I can think of is to make a cable that has a BNC connector on one end and an F connector on the other end, RG6 or RG59 will work for this. Once you have an F connector on one end and a BNC on the other connect the BNC end to the video out of the DVR then connect the F connector end to a cable splitter, then just run standard CATV cable to each TV. Should do what you want and should be pretty cost effective. Or you could go BNC to RCA then use an RCA splitter, no need for any overly fancy setups.

Having the camera hooked up to a display monitor for testing purpose can save you a lot of time of finding out you have cameras which are showing upside down pictures and off tilt pictures. But garageguy is correct, unscrew the bracket holding the camera in place and rotate the camera then screw the bracket back in.

Ground Loop isolator perhaps?

Is this a Windows based DVR or Linux? If it is Windows take a look at the services.msc snapin and just make sure there are no odd settings.

Hey Soundy, Ideally I need the camera to be good for Day/Night and Hi-Res would be nice, low light isnt a problem as the lights are always on.

Hey guys, Looking to start shifting to network/IP cameras and move away from analog cameras. What additional hardware is needed to install network/IP cameras? I am aware I will need the cameras, and power supply or PoE injector, but is it as simply as connecting them to a switch then trucking the video into a computer with a RAID array running something like Geovision software? Is it much more complexed then that or is that about right for the installation of IP cameras?

So I will be mouting some cameras to a high ceiling about 30ft high, and would like to drop the cameras down about 10ft or so. I will be mounting dome cameras. Does anyone know of any mounts that can allow me to drop down a dome camera from a ceiling? Im sure I could come up with a solution of my own, but would look better if I could use a proper mount to accomplish this. I was thinking something like a ceiling mount, conduit pipe or something going down the length I need and some sort of mounting base? Anyone have any suggestions?

One piece of advise I can give you if you are going to run cabling through a wall, is run your stud sensor up and down where you plan to drop the wire, this can let you know if you are going to hit a fire block in the wall or not.

Hello All, This is probably a noob question but I am going to ask anyways. Do box cameras use the same BNC connectors as a bullet camera or dome camera?

How many of you actually connect your motion detectors or other alarm system detection products to your cctv system to trigger motion based recording? I just bought a test system for myself to play around with and am thinking about testing the built in motion detection against that of a motion detector from an alarm system. Do people find this to be useful or just extra wiring to install?

That security bar looks like it is most likely blocking an activeX controll or soemthing from running which is why you are not seeing any video, check your security settings something is being blocked.

Hey guys, saw this today while I was looking through some security news. Apparently Trendnet security cameras have a security flaw which allows the video feed to be viewed on the web without the need for user authentication. Below is a link to the article. http://packetstormsecurity.org/news/view/20557/Trendnet-Security-Cam-Flaw-Exposes-Video-Feeds-On-Net.html

For your external IP address to find the DVR make sure you have your ports forwarded to the internal IP address of the DVR or else it wont matter if they have your external address your router wont know what to do with the connection.

Increase the IP Pool to 254 and see if that works, something tells me the dhcp pool only has 32 addresses, however this shouldnt be a problem if you have the DVR set to static. I dont see any problems on that page otherwise, like I said try a higher port also.

Depending on what kind of network you have, you might have to be creative. If you want ALL the traffic, you'll need to put an old-fashioned hub in between your target, and the network, then hook your sniffer machine to that hub. Hubs repeat all packets to all ports. Alternatively, you can overflow or poison the ARP cache on a switched network and get the data that way. You can achieve the same effect by switching your card into promisc mode. However you will only get what is on that switch segment, so if you have multiple switches you will not get all the traffic.

One of the big questions here is are you trying to control the DVR from 3 locations or simply view from 3 locations? If you want to control I would say soundys idea is best, if you just want to view then tomcctv has a great solution.

I like this idea, was just about to purchase 2 motion detectors to throw onto a test setup I am running with a cheap 4 channel DVR, now I think I will throw a siren and some strobes onto my order as well. I would be curious to see the 'relay' when you are done as I think what I am picturing is vastly different from what you will have.

It is important to know if you want to receive traffic not destine for your network card you need to tell Wireshark to switch you into promiscuous mode, basically tells the network card I dont care if its addressed to me I want to see it. I dont remember if wireshark does this by default or not. HPing is great if you want to send specially crafted packets.

Are you sure his router is using 192.168.1.1/24 as its DHCP pool? If the router is set to use 192.168.0.1 as its network then you would have a problem. Also try picking a high order port something above say 2000 its possible port 90 is being used for something else, I believe it has an assignment for another application.

No, most likely those settings will not work, its possible they will but probably wont. Go to a computer go to start > run and type cmd then once the command prompt is open type in ipconfig /all This will give you your computers IP address, DNS servers, Gateway, and subnet you will most likely not need to worry about the 255.255.255.0 is fine. Once you have that information, you will copy your DNS and Gateway to the DVR as you see it on your computer, now for the IP address you need to pick an IP which almost matches your computer, if your computer is 192.168.1.101 then use something like 192.168.1.150 for your DVR. I can speak for your router, try clicking through the different tabs until you see the one that covers IP configuration.

As long as you install the new drivers why wouldnt it work? Where I work we deploy 1 corporate image to all systems, desktops and laptops all with different cpu's and mobos, we just included all the drivers in the build, if its needed its used if its not well then its there anyways.

A lot of tools you would use to do electrical will prove helpful. Wire stripper Wire Crimpers Viewing monitor knife Compression tool CAT 5 crimper I dont have my tool bag on me and am having a brain fart as to what I have in it. If you search the forum for tools I know this topic has been discussed before.

Why connect a hard drive to the router? I see this adding complexity to the setup as most times they need to be added as mapped network drives and most likely a standalone DVR running an embedded linux build will not support this. Having the HDD connected to the router will do very little to reduce the amount of traffic generated. If you have tons of money to spend whack in a Riverbed WAN optimization appliance which will help optimize the traffic, I kid I kid, those things are in the 10's of thousand $ range. I think this is all going to come down to the upload speed you are able to get.

See if there is some sort of eject button on the software running on the DVR, most likely the DVR is using a linux embedded build, and I know from experience Linux gets very mad if you write something to a usb key and dont dismount it, usually wont write the files.
