How about this for a CCTV News Story
Numb-nuts replied to Numb-nuts's topic in General Digital Discussion
I'll see if I can get his address and you can go round n sort it out for him! I think it was that he didn't ask permission, which he should have done, Public departments and social associations hate anyone doing anything without permission. ~They see it as contempt. -
What method you use depends very much if you have a monitored system or a unmonitored system. If you have a monitored system I would humbly suggest a couple of static mini power zoom cameras at either end. That way the security staff can zoom in or out depending what they want to view. Positioning is something you will need to asses yourself to get the best out of it. By the way, regrding the video, an operator can select and change the subject that the camera tracks at will. These auto track systems aren't much help unmanned but are very effective if manned and aid the operative in gathering footage which may become evidence later. Even guided missiles need a human to punch in the data. even if they are 4 years old.

Security Camera feud sparks privacy questions
Numb-nuts replied to nDAlk90's topic in Security Cameras
Is there anything stopping the lady from planting really fast growing trees on the relevant side of her house? Thats what I would do, plant a row of Leylandii. A fast growing evergreen that is also a haven for nesting birds and grows at the rate of approximately 1 - 2 m per annum. Then the shoe will be on the other foot. Let the guy looking into their garden put that in his pipe and smoke it. What a nerve looking into someone's garden. I wouldn't dream of doing that Give him some nice trees to look at! ................................................ -
Howdy Partner Yeah when your not an enthusiast or a pro then CCTV set Up can be quite puzzling. Knowing the capabilities of the system and what to look for can be even worse. Fortunately you have Geovision so there will be many members on here that can advise you.

4 Camera one Cat 5 Cable and power any one Done? Issues?
Numb-nuts replied to AndyA's topic in Video Transmission/Control Devices
Then at least it wasn't just for no reason. I saw a livery stable this weekend where they ran 7 cameras from the farmhouse, to the stable block over a steel support wire. Two cat5 cables over to the stable block and then 2 x 4 way baluns. From there the cameras were fed by coax and that was where the PSU was placed to distribute the DC power. To be fair to the installer, running 4 coax or 4 Cat5 would have been unnecessarily bulky and expensive so in such a case I think what was done was well reasoned. Fortunately I was only there to adjust and re-focus and clean the existing camera housings. -
You need to specify the horizontal distance from the camera to the FOV ( approx. distance from camera will be calculated using pythagorus) and either the scene width or height then you can use a lens calculator to determine the appropriate focal length. That camera uses a 1/3 " CCD sensor. Depending on the actaul calculation you may have to buy a varifocal lens if the precise focal length is not standard.

Listing the existing cameras and which ones need replacing. You need a special cleaner for plastic domes, such as ICI cleaner for polycarbonate. Or I use plain water and a micrifiber cloth. Some very mild soapy water to wash off any water scale then lots of plain water and dry with a microfiber cloth or terry towel. This may help: I think this is the operating manual for that DVR

Hi You should be looking at two cameras to view the driveway, one for an overview and one for more detail, if you are going to identify anyone. Pay attention to lighting as many of the anti-social events will take place after dark especially now the winter is with us. These points on which you plan your system are known as Operational Requirements. The name is self explanatory but fundamental to achieving a suitable system.

Hello Andrew, where are you in the UK? I am in Manchester, originally from London where I still do a lot of my work. I still travel there at least once a month. If you are re installing a system someplace else, before you start you will need to plan what you can use that you already have and what you might need to replace or uprate. Let us know what the system is and what the cameras are. I am sure you know how to plan the wiring routes, so next you need to identify where you will need wide angle shots, a wider general view, and where you might need closer up shots that can identify either vehicles or persons. Lighting during darkness is always important, light should not hit the camera and IR should not look directly at the object/person, but across would be better so no washout occurs. You can wire with either coax and twin cable or you can use Cat5 or 6 with baluns at either end. The baluns are the preferred method in most cases today. Work out the length of cable runs. You can either use a box of Cat5 or 6 cable, (305m) or you can buy shorter runs which you can buy quite reasonably on ebay. Anything else you want to know we are here to help.

Please help a newbie start a system
Numb-nuts replied to Famester's topic in IP/Megapixel Cameras and Software Solutions
I am sorry to tell you, but Coax and DC power siamese cable is purely for analogue CCTV. (There are hybrid IP cameras and servers but I am not up on those) IP cameras work on Cat5 or Cat6 cables. with RJ45s at either end either into a server or direct into your router. I am not aware of the market in the USA so I won't advise you what is available and your options, but should you decide to rewire with Cat5 or 6 then you could use the siamese as a pull through. Cat5/6 is always the best option now because of the convergence of networking and video surveillance. If you want to go analogue and use a DVR as video server you can connect to your network that way. There are also hybrid recording devices aswell as IP servers and NVR/servers. -
Hello Rachel, welcome to this mad place! We sometimes like to have a joke and today seems to be the day.

Luke, I know this is not what your question was but both the domes in the pictures are at risk because of their proximity to the yard wall. With all that wood piled up there, it is even easier to attack and even steal them, the telegraph pole you can't do anything about. Remember thieves lose nothing if they damage the item they are stealing. They would wrench it off the wall and cut any wires. If you can't relocate then at least try and fit a cage. The garden you are looking into, I take it the neighbour has consented and that you are doing them a favour? That being so, get them to have you install a PIR operated security light that way if someone did enter that garden, yard, then your camera would see and record. Is it the yard across the alley from you?

Anchors for Hanging PSU in Cinder Block
Numb-nuts replied to vmgtlexi's topic in Installation Help and Accessories
Nice one. Oh yes I forgot about those. I've seen the but never tried them. In theory they should also work well as the material in cinder blocks will compress under extreme pressure. Not sure what weight they will support, check before you make a decision. -
Anchors for Hanging PSU in Cinder Block
Numb-nuts replied to vmgtlexi's topic in Installation Help and Accessories
The mortar is weaker than the block and only very light objects should be secured to the mortar. You have a couple alternatives. You can use no.12 plastic plugs with either no.10 woodscrews or carriage screws For each 10.lbs of weight you should use one screw and try not to make it more than 1/2" longer than the plug. Account for this depth when you drill your holes but don't drill much deeper than you need to. Also don't under drill as the screw passing the end of the plug could fracture the block and this weakens the plug's grip. Use a light masonry drill with a hammer action drill and if you must use SDS then be gentle with it. Don't use metal wall anchors unless they are sleeve types and the expanding type can fracture the block again loosening it's grip. You can use smaller plugs and screws for the bottom screws as the weight is supported on the upper screws. -
I'm in awe of the bracket where canI get one?

You could catch your foot in there and never emerge again... -
From now on, someone comes to my home I don't take my eyes off them for a second. If I have to leave them, out into the street they go to wait for me. It never occurred to me that could happen and I thought I was pretty security conscious. Wait a while before you do anything, as you said let him 'THINK' he got away with it for a while. The impact on him when you do finally catch up with him will be far greater. If he called your cellphone or landline a record of his number MUST exist with one service provider or another. When you do catch up with him; You can either turn him in to police or get him to buy you another more expensive stroller and to pay you for the refrigerator again. When I was a teenager, working on Saturdays in a mens fashion shop, if we caught shoplifters, we made them buy what they were stealing or we called police, sometimes both.

I believe those are tamper resistant Torx either T20 or T25. I would buy a small set, you need only carry two main sizes in your toolbox Here is a great set on ebay.com about $16.00 item no: 280652092348 Hope you are doing well Eric, nice to see you back again.

How about this for a CCTV News Story
Numb-nuts replied to Numb-nuts's topic in General Digital Discussion
I suspect it was precisely that it is a CCTV camera that the Landlord asked him to remove it. The story mentions that people have put up satellite dishes and have not been asked to take those down. The idea of CCTV just frightens some people. He should have asked permission first. -
Budget Camera for use in enclosure, day/night
Numb-nuts replied to Rally_Rebel's topic in Security Cameras
Why ? Because it's his first post and he's put a retail website in his post and sung the praises of Swann? Naaaaah, too simplistic. If he is a spammer, he's wasting his time here. and if he's not, welcome to the forum James. My name is MUD now that I let on that I installed a Swann system for someone -

Numb-nuts replied to Rally_Rebel's topic in Security Cameras
If you are happy with Swann equipment I am pleased for you, but it is overpriced lower end stuff and is thrown together for a popular market who just want to buy a complete kit without going into the technical side. Some members on here tend to become a little too serious about CCTV and expect everyone to have the same obsession about it. At the end of the day Swann is better than nothing at all (only just) and depending on expectations it may suit some people. Just to clarify you would be unlikely to find a professional using or installing Swann equipment, but you don't need an Estwing hammer to hammer in a single nail. I don't work on CCTV full time, just some jobs, and I wouldn't dream of supplying Swann. I have installed a Swann system for a homeowner who had already bought it. He was delighted, so who am I to burst his bubble? Some people seem intent on bursting yours, not sure why but keep on smiling... By the way stick around you may learn something I know I have.
