Obviously not convinced they'd be any use, its that attitude we don't care to pay money to a technician to fix the problem then they'll moan and groan when something happens that might have been recorded but for their laziness or greed. Ive see cameras with cut cables at the rear with a sign beware CCTV Recording it's laughable.

I have just finished reinstalling and upgrading a CCTV system in a local restaurant, It tok about 5 days and for at least 2 of those days I was crawling around the ceiling space above the restaurant area. The space was so limited in height that to get to anywhere I had too crawl in elbows and knees in some places had to crawl on stomach to gain access. On top of everything else there was no light whatever other than my head torch with 15 L.E.D.s in it. Distances to crawl to were up to 25m which I suppose isn't too bad but it was uncomfortable especially as I once became trapped in a crawl-space and had to be rescued by fire brigade. (less said about that the better) Today we received out latest tool additions (a monthly occurrence) and I received a rechargeable LED floodlight with 108 LEDs and no trailing wires. "Just what the doctor ordered" I thought. Frankly I would have appreciated this last week, so it's typical that we get these things a week after we need them, okay it'll be available to me next time. The picture shows the one we got, a Kobe branded, it has a Li ion battery which at full charge should last 3.5 hours. It's also very light which surprised me. The downside is obviously that it takes 5 hrs to charge, but who wants to spend more than 3.5 hrs in a dark space anyway. The unit comes with a vehicle cigar lighter charger too, which I thought was pretty nifty and charges within an hour using that, while the engine is running. I thought this might be of interest to anyone facing working in dark spaces lofts under-floors, service cabinets etc. These are available in many places under many brand names and are now widely available under many brand names and from many tool suppliers and wholesalers. Our ones are from Cromwell tools but these are also available in many electrical wholesalers such as CEF, SND and others.

sorry to laugh but I have had similar mishaps but I've been lucky not to suffer broken bones Hope your little piggy is recovered now. It's the smallest injuries that hurt the most sometimes, splinters, fiberglass irritations etc. Not my only mishap ever I assure you. One potentially deadly one that springs to mind we worked at a place surrounded by double yellows and the only place to park was a narrow raised area adjacent to the building. I parked it very close to the edge as we needed access to the side loading door on the nearside, When I got out the ground was about a foot lower than the surface we'd parked on. Just imagine if this had been and further or lower I might have disappeared out of sight and without a parachute. Also I am always parking up only to find I parked adjacent to a huge puddle!!!!!!!! (Whats that you say?) No chance, I moved the van... And one christmas I was given a double tool belt, loaded it up fully and climbed a ladder only to have the tool belt dislodge my trousers to my ankles and my apprentice couldn't stop laughing long enough to rescue me, (pull em up for me) needless to say the toolbelt was consigned to the garage ever since. You were right mum, always wear clean underpants! We try to learn from our mistakes but inevitably we don't

Beware of Cantonk and other cheap chinese manufacturers

It would help to know what DVR you have make and model. Most DVRs seem to have a web interface that requires IE with active X or some form of plug in. If your DVR is Hikvision you should be able to use most browsers to log in even on a Mac BUT NOT ALL!

Of course you could always take the easy way out.

Oh THAT piping, thought I was going mad,,, Sorry for not understanding. For runs upto 25m we use 32mm (Inside diameter) indestructible water pipe in a single piece. It has a bend radius of about 1.5m and so that needs to be taken into account when entering and leaving the ground. We also pull in a draw rope but we do it in advance of installation and pull in another draw rope with the cables so that one remains in the conduit after installation.It is essential for pullng in new cables and adding more in the future. Take a look at youtube for tips and tricks when using undeground conduit. There are some really great tips on how to tie a draw rope to cables and how to get a drawrope through conduit before installation using a vacuum cleaner of all things.

Remote Viewing / Set-up help required
Numb-nuts replied to BroxSec's topic in General Digital Discussion
I cant try to help if you provide information. What is on the software disc that came with the DVR and looking in the networking smenu what ports are default HTTP ? Mobile Monitor? Remote Monitor? RTSP ? ( found under the Netservices menu sometimes) Please provide a screenshot of the main menu -
IF you buy ready made cameras typically the varifocal lens will take you to 12 mm, however you can choose your own lens id you assemble a body camera with its own heated housing. From what you say it would be a bit of a sledgehammer to crack a nut so I wouls opt for the 2.8 ~ 12mm ready made ir cameras. Cost is relatively cheap when compared to the first option.

Password and Username are essential as hackers cane get into even the most secure firewalls. It beggers belief when I see users setting up their admin accounts with no password or the default password which can be found openly on the WWW. Not being a computing expert, you need to introduce some form of firewall and port forward it. What about a sub=wifi network?
-
Have you tried setting this up on an alternative PC separately? I am not sure what the issue is with yours, but it can be your PC itself. and I mean a hardware issue. I am not a computing wizard and subscribe to a support service for such matters, they tried and failed to resolve this matter on a client's machine and even their best techs couldn't resolve it after 16 hours on this issue. First eliminate there being an issue with the DVR by trying on another PC. If it works on another PC don't waste your time re installing your operating system, you will need to replace your PC ( UGH ! ) Sorry for the negative news but I have suffered this issue also and it was the PC hardware. Correction, I remember now that it would load no problem in safe mode but otherwise we had to give up. sorry for the vagueness!

Sorry to advise you the following but I have found Medusa's to be nothing but trouble when setting up for remote view and the remote client zoom function, don't even go there once the client wants to zoom in. Its as if the zoom function has a gremlin operating it separately. As a result we sold them off cheap on ebay just so we wouldn't have the aggravation with this DVR. Also we ended up replacing three of these for our clients replacing with other DVRs. We want our customers to have a good experience and not suffer the peculiarities and problems we had with this model of DVR. Lets see if we can help you anyway, what router do you have and who is the service provider?

Camera positioning! There may be lihts from other properties which don't look too problemeatic to you until viewed through a video channel. These things have to be taken into account when selecting a camera position.

Unable to view Sentient 960 cameras on Phone (works on LAN)

If you reserve the DVR IP address in the router, you can either use the DHCP or not as suits your needs. The router will always allocate that DVR with the reserved IP address, leaving it static won't make a difference if you do this. You must allocate the ip 192.168.1.100 to the DMZ on Thompson based routers. Not I deal but they don't work otherwise If you want to check your open ports you can go to you get signal port checking tool and type in the port numbers. Conveniently it comes up with the IP address automatiacally filled with your network's IP address and port 80 ready to test. I use it always and it is always accurate. -
WHAT ARE YOU TALKING ABOUT? PIPING? HAND-HOLES? 3% SLOPE?
-
If you understand that much, you should be able to select a router that does not use the DMZ for port forwarding. Alternatively you could use a cloud based service if your DVR has that facility. Personally if I were going to replace my router, I'd opt for a Draytek or Netgear. Security is reasonably good on the Netgear and terrific on the Draytek

You can do precisely that and using a more local power supply to reduce voltage drop. You should maintain a voltage of 12VDC + or - 10% at the camera. Staying within this range you should not have any issues provided the power supply has a suitable amps rating for the supported cameras. Also remembering that orange pair is chan 1/5/9 or13 white stripe conductors being pos, you could put a single channel balun (twop in a pair) at each camera and splice the video cable to the video return where your second balun is shown. You can then use the remaining three pairs to carry the power to the camera. Remember to adhere to the rule that the white stripe is pos and seperate the three pairs into white stripe and solid colours the solids twisted together being the neg line. We do this all the time, but you are relying on the manufacturer of the 4 way balun to adhear to the TIA T568B colour code Chan1 = orange pair Chan 2 = green pair (split) Chan3 = Blue pair Chan4 = ~Brown pair White / Colour conductors are POS The solid colours are Neg Then your colour code should read Pin 1 + ve W/0 Pin 2 - ve orng Pin 3 + ve W/Grn Pin 4 - ve Blue Pin 5 + ve W/Blue Pin 6 - ve Grn Pin 7 + ve W/Brn Pin 8 - ve Brn We have extended this to our own wiring that any CCTV engineer who happens across it can quickly understand the wiring and have written a tutorial which I have PM'd you

The LOW TECH way of letting people KNOW they are on cameras is yo tell them with a sign. Not exactly rocket science is it? I don't see the point of HIDDEN cameras, in all but exceptional circumstances it's desirable to let the subject know beyond any doubt that they are on camera to deter any misbehavior and to persuade them to think twice before doing anything wrong at your door. "An ounce of prevention is better than a pound of cure" and all that.... Often times I see a new client and they say we want 4 hidden cameras. When I enquire why they want hidden cameras they mostly don't know the answer. They just think that it's clever to have hidden cameras like they see on some TV shows that feature covert CCTV footage. Anyway getting back on thread, the main problem with door cameras is that the subject is standing blocking the light. You could use an intercom camera that has LED support but it will not be hidden and be rather overt which could be an advantage. MY own is a purpose made front door camera but as said before they are far from perfect. They do look just like a slightly larger peephole viewer and to the average person, go unnoticed. When a subject is close enough to ring the doorbell (Presumably the bell push is in the door frame) and the camera is placed in the door itself, high resolution isn't that important although its not an impedance either.

Sorry if this doesn't help, but I couldn't resist !
-
I have thought about how I could make another style of camera perform this job, but frankly it's not an economic option. I wouldn't be able to sell what I could produce. If money were no object sure I could design one for the specific purpose and get it made in qualtity in China. Frankly nobody else has done so because there just isn't a high enough demand.
-
Was this a robbery or a burglary?
-
You will find that the biggest problem with peephole cameras is that because of their location, the light is blocked by the subject standing directly in front of both the camera and blocking the available light. Rather like a person standing between you and a vehicle headlight.

Have you got a BB Gun?

Yeah why so keen on using the wrong product? You seem to be looking for an endorsement of RG6, fact is it MIGHT work but chances are it probably won't be as good as RG59 or CT100/125/165
