    Looking to get into the cctv field

    Safety gear is for wimps eh? Well you just carry on without any safety gear, if you believe that makes you more of a man! Personally I have no concerns about being a wimp if I'm a safe uninjured one.

    Looking to get into the cctv field

    I am 57 and I still crawl around in attics , although I pay for it the next day. A good set of 'wire fishing' rods is essential. Also a well fitting bump cap to stop you smacking your head on nails and joists all the time. There are some excellent courses online for CCTV installers now google Tavcom Training.

    ends cut of cctv cameras

    so you are now half way there! Discover the model numbers and google them and has been advised you should have little bother finding the instruction manuals. If its a speed dome i.e. PTZ, you will need a controller and the DIP switch settings, if it's a static dome there are other issues you will need to deal with Statics; Some better domes have built in UTP connection point and therefore may not require a BNC. You can find out by asking if they had baluns at the DVR end, or by opening the dome and seeing if there is UTP marked on the board where some of the wires connect. Also the emergent cable wont have any coax if it uses UTP. Below is the typical layout from a Pecan dome camera which has a built in UTP point (i.e. built in balun) you can see the DC power and video inputs to the left and the UTP input to the right. If you are using coax, then the braid goes into the -ve terminal and the center conductor goes into the +ve terminal, then you'd terminate with a line jack as pictured below BNC line jack

    BNC Compression Fittings

    I always use the 3 part crimp BNCs as I always have done, they do not give me any problems. I always glue a strain relief boot to the cable and ferrule and secure the coax with a semis flexible 'rapstrap' (see below) to prevent snagging and pulling on the BNC. I have tried and was impressed with the compression type BNCs, but at the moment they are expensive here in the UK It's hard to choose between the two types of connectors, so for that reason I have remained with what I know. I have the tooling for both types of plug so that has not influenced my decision. Some of the compression plugs are referred to as watertight, although I can't see the advantage as I would never leave a BNC exposed to the elements where water could get in and moisture is never a problem either. I feel there is not a lot to choose between the two types. below are rapstraps, they are semi flexible cable ties that do not change the position of the center-core of coax, in relation to the screen. See the video
  7. Now there's an idea, but cheap is a word that is alien to me Ya, me too. Maybe I could get it at Comic-con and is would have the super hero CCTVMan. I need him here in New England bad. " title="Applause" /> Frankly, we need him here in Old England too....
  8. We are talking about budget cameras that draw very little even with their IR lamps running. If power dictates it, a heavier cable must be used. I don't need to hold anyone's hand, we all are responsible for our own work. If someone hasn't the noodle to work it out, they shouldn't be attempting it. I do not have to state the obvious and be 100% specific on EVERY POINT or I'd have to write a book
  9. Try this tnx sir, God bless After you learn the basics of using Cat5, you can get creative and start creating all sorts of distribution arrangements using Cat5. I did one today it was only a domestic user with two cameras but she may add two more later. For the cables, I used two Cat5 cables one carrying the signals for upto 4 cameras and the other carying the DC voltage (2 prs pos, 2prs neg) up to the first distribution box ( a slightly larger Junction box) In there I wired the first camera and took an external cable to the second camera. It helps if you have a wiring convention, mine is that solid colours are +ve and white/stripe are -ve. At the distribution box I inserted a DC splitter cable then powered both cameras from that using the second camera's cable to carry both DC power and video signal, A single pair for the video, and the other three pairs I split into 3 solid colours (+ve) and three white & stripes (-ve). This arrangement worked a treat and I am able to add two more cameras without running extra cable in the house. I just need to run the extra cables for the new cameras from the distribution box when I need to. When I run DC power down Cat5 I always twist the solids together for +ve and white/striped together for -ve Taking that wiring convention to the video pair I use the solid blue for video +ve and the white/blue for -ve (ground). NEVER run power through less than 3 prs

    masking dedicated micros dome?

    Hey Luke How are you doin' ? In my limited experience of PTZ domes the masking is done via the OS menu. Usually you can do this from the keyboard by accessing the OSM by typing in Call+64+enter (this is a fairly common command but, may be different on DMs ) then you would use the joystick or movement controls to select menu items. Then there are different types of keyboard that do not have the enter key on which case you just call the preset to enter the menu and call+ hold down the preset key to exit. Hope this give you something to work with

    First time CCTV homeowner and clueless

    It always helps if you say where you are located (town and country) approximately (not the address obviously).
  13. In one of the other threads, I was reminded that what you see on CCTV recordings can be open to interpretation and things may not always be as they seem. It reminded me of a

    Why is CCTV interesting to you?

    any video is subject to misinterpretation, you have to be very careful not to get the wrong end of the stick, when you see something it's not always what you think so a little caution is called for. I always remind clients of this when they are new to CCTV.
  15. I was not criticizing you description, it was quite good,
  16. Those are both terms that refer to the lens, if you have a built in lens then that explanation od closer to correct but it is the lens that is vf and ai. An Auto Iris lens is used where the light changes throughout the day. A fixed Iris is used in a location where the light is fairly constant throughout the day. The advantage of varifocal lenses is that they can be used in a wider range of applications and the lens can be varied to suit that location, either zoomed in or out according to the desired scene. This makes such cameras more versatile.

    Why is CCTV interesting to you?

    I would agree with that, it feel like someone has cut off your head when your system isn't at your disposal. I have clients that are very calm and relaxed most of the time but when a camera goes down I see the other side of them panic stricken as if their life were in danger

    Why is CCTV interesting to you?

    The one thing I really love about CCTV is that it never lies, it evens things up a bit and gives the would be criminal more something to worry about instead of the victim always being the upset party. Sure it's not perfect, but until we have police officers on every corner, it'll keep the criminals worried or concerned. (not all of them obviously) By the way it's Jan 1st 2013 here in the uk so Happy New Year everyone....!
  19. this is only a concern if they'll be exposed to direct sunlight. under the eaves, tucked into siding, on the shaded side of the house, uv isn't a problem. This is just fine for DIYers decidng if they want to shell out a few extra dollars, but the diffeence in cost to a professional weighed up against the cost (and inconvenience of having to strip out and redo failed cable it isn't worth the saving on the off-chance. Besides, the client paid for the best job you are capable of, we owe it to them to ensure their wiring is at least as good as it needs to be if not better and not penny pinch at every turn. No offense meant to anyone by my terminology, it's just the way I feel about under-specifying just to save few dollars.

    CAT 5 cable and multiple cameras

    I sometimes run a single cat5 for each camera and it carries both video signal and power. I go by the convention that solid color is pos and striped color is neg in amll things. Now select a pair for your video and open the other pairs and twist the solid colors together and the striped colors together to carry the DC power Video pair the solid is pos the stoped is neg DC pairs the solids are pos the striped pairs are neg and use screw on terminal DC connectorsat either end a plug at the camera end and a socket at the DVR end. Of course you're better off with a single power supply with enough power to run all your cameras. Actually I run mine through a fuse bank but it's really not essential.
  21. Just never be tempted to make a direct splice in the cable. I've seen some dreadful splices, some barid and conductor side by side into terminal block, some where they've soldered the center together indulated it with "chewing gum" or blue-tac , wrapped in foil paper (probably the gum wrapper) and joined the braid around the outside and wrapped again with PVC tape DISGUSTING! Next time I'm going to take a photograph and post it to this forum. Use connectors and seal with 'self amalgamating' tape or 'heat shrink tubing' or in an IP rated junction box.
  22. Domestic CCTV users being targeted for anti-social-behaviour (ASB) The worst thing you can do if you are being targeted by neighborhood youths is confront them. If this is something that you have done in the past, you may have unwittingly precipitated this behavior yourself. Having a CCTV system in your home, is likely to increase the chances that you might do it again. Great, now you have CCTV use it to your ADVANTAGE. Always make sure that anyone passing your property KNOWS you have CCTV by making very sure you put up signs that can be readily seen, and do not hide cameras. Hidden cameras have no deterrent effect whatsoever. If groups of youths are gathering outsideor near your home, and their behaviour is making you increasingly nervous, simply sound your intruder alarm, the noise will eventually drive them away if not immediately. If they're up to no good they'll go immediately thinking “I don't want to be here when police arrive” DON'T go out and confront the offenders, the best thing you can do is stay calm and hit the panic button on your house alarm and if necessary call police. Confronting offenders at best makes the problem worse and at worst could get you injured or killed JUST DON'T DO IT !!! “ but they're damaging my car” my answer, “Cars can be repaired” A word about cars, if you bought CCTV to watch over one or more cars, park them as close to your home as you can even if it is on the street, set your DVR beeper to beep on motion detection and then if you see someone interfering with your car you can sound your intruder alarm. The last thing vandals and thieves want is attention and alarms get them attention It's also a good idea to get your DVR connected to your TV set, or view on your computer or both, so that when you hear something you can respond in a calm manner. Also it's a useful idea to connect a wireless mouse to your DVR and have the mouse by your TV. The range of most wireless mice is about 10m or 30ft, but if your DVR is out of range, purchase a USB extension cable and run it to a convenient place within range of your TV and insert the dongle there. This is a neat trick I use on many of my commercial installations, I usually run USB extensions inside the ceiling cavity but it only needs to be close enough to the TV location for the mouse to work and the dongle doesn't need to be in view. Now relax and let the CCTV work for you.
  23. I think he's referring to the small circular junction that we use with 20 or 25 mm round conduit. OR
  24. Vloss means your cameras aren't sending a signal. First thing to check if they are all on a singlr power supply or gang of sockets.... POWER Then ask what else do they all share? Same DVR, surely not. ah but I hear you say it's a new DVR makes no difference, check with a known good camera.
  25. I don't know how I've gone al these years without a WIMAX, I wan't one for christmas, santa are you listening?
