I saw your PM of the cameras. I use a camera that are very similiar to the one you showed me. I have several 16 camera, and 16 channel power supply set ups. I have not had a problem with any of these systems. I am still scratching my head on this one. I do not see too much of a problem with your set up. Except not having a fuse block. Things that make you go HMMMM! What country is this set of yours in? I am going to stick my neck out on this one. I think you have one camera that has a short to the chasis of the camera. Did you pre test the cameras, and did they work prior to the install?

I use something similiar to this: 12-Volt DC 16-Output Power Supply This power supply provides 16 regulated and fused 12VDC outputs. Metal cabinet. Regulated 12VDC, 8A Individually fused outputs Individual LED indicators UL/CE listed Dimensions: 311.15mm x 311.15mm x 101.60mm (12.25" x 12.25" x 4.00") Be sure to check out our power distribution products and rechargeable batteries for added flexibility.

I am still scratching my head on this one! I guess those cameras are more sensitive then I thought they would be! You said the original cameras are still working! Thats good to know! Can you PM me what kind of cameras those are. I would hate to go on a blind service call and POOF! OOPS! Exit stage left!

Hey photys! Good work on the artwork!!

If you own the pos system you do not need a license. Will you be using the Hikvision cards? If you are leasing the POS system you may void any warranty that may come with the system. At the worst you pay labor to have someone come out, and restore everything back to working order. I have bumped in to a company that refused to give me tech support to hook up our DVR to their system. If I broke it, I pay for it. I said thank you very much, and hung up. The owner cancelled 300 pos systems for his state wide business, and he has switched vendors to one more to our liking. I received a very interesting call the next day. It sounded like someone groveling? I would suggest making a call to the POS company for more info.

I'm sorry. My mistake. I did not realize that your TV had a VGA input connector.

They work depending on the fuse itself. Some are heat activated, and some work with current. Some are actually designed not to blow right away. These are called slow blow fuses. Fuses are designed to melt when a threshhold of current has been reached. This is to give you an indication that there is something wrong with the circuit, and you need to address it right away before you restore power. It can be difficult to trouble shoot when a fuse blows for no reason at all. In florida fuses in devices can blow during lightning strikes. It may not be enough to see the lights flicker, but if there is enough of a flicker a device may blow a fuse because the threshold of current has been reached. Manufactures may spec a slow blow fuse so that the device can take momentary, or close to the threshold current without blowing. This helps in reducing false situations. There are some circuits that are sensitive to a certain threshold, and the fuse is designed to blow very quickly saving the circuit. Sometimes these circuits can be very aggravating, and people will substitute a higher value fuse, and in return they blow a device without meaning to. If you look at a fuse you will see what voltage range it is designed to work with. Some are low voltage such as automobile circuits, and some work at 120 volt range, and there are very large fuses that the Electrical companies use. Circuit breakers in a house will usually work off of heat. When there is an over current situation, there is heat involved, and the circuit breaker will trip saving the circuit. Power supplys for CCTV in the U.S. will come with fuses that blow, or they will come with a self resetting fuse. There are advantages, and disadvantges with each style. If you do not have spare fuses, and one blows then your circuit is down until you can obtain another fuse. It is always recommended to pick up extra fuses in advance. When trouble shooting a blown fuse you can replace it. If the circuit works it does not mean that it is fixed. It can be an intermittent problem, or it can be a time delayed issue. When the circuits heat up it may fail again. Never wrap a fuse with tinfoil. You may cause a fire. If fire marshalls can pin it back on you, then you may be in a very embarrasing spot! If you pop in a fuse, and it blows right away then you have a really bad situation. If you have multiple items running off of one fuse, and you are having problems defining the problem, then remove everything from the circuit, and start adding items one, at a time until the fuse blows again. This will help identify the culprit. You may still have another device that may throw the fuse later when it heats up, so keep this in mind as well. Do not forget that it may be a problem with the power supply, and not the circuits involved. A power supply can have an internal self saving device that reacts with heat. It may shut itself down to protect itself from being destroyed. In the process of trouble shooting circuits this kind of issue will make it coincidental that a particular device is to blame. You remove a camera from the power supply, and you look it over. You turn everything back on, and now the system works fine. Later the cameras go down again. The power supply was cooling off while you were "playing" with the camera (or what ever device). Be very careful with power supplys that come with DVRs. If the inside power supply of a DVR blows it can blow the power supply that is external of the DVR. If you test this power supply on another DVR you may blow the 2nd DVR. You really need to do some good checks before you hook it up to another DVR. http://www.fuseone.com/fuseology.aspx http://electronic-components.globalspec.com/Specifications/Electrical_Electronic_Components/Electrical_Distribution_Protection_Equipment/Fuses

If you want to do a system by yourself you can do it! It is not simple. Matching a DVR (PC/embedded), cameras, lens, IR distance, and making it work, and doing in a budget is the hard part. When you put your system together think like a pro! Where does the sun rise, and where does it set. At any time of the day will a camera be blinded by the sun? Think about summer vs winter. Where will the sun be in winter? I receive a lot of repair jobs right around winter time. DIY will install cameras that do not work in the dark. Every thing is great during the summer. It gets dark around 9pm, and most people leave their business at 6. In the winter time it gets dark around 5:30 pm. When they cannot see the parking lot, and the cars they get a little nervous. The next day I am the first check mark on their to do list. Fix cameras. If I know what DVR I am going to use then I "work" my way backwards to determine what kind of camera I am going to use. The camera will determine what kind of power supply I will use. If I know what camera I am going to use then I work backward to determine the correct DVR for the camera. Will you use the internet? This will determine the DVR, and from there you can match a camera to the DVR. Budget verses Security is of the Essence! Budget = less cameras. Security is of the Essence (S/E) = more cameras. More to see, or one camera watching another camera. Budget = cheap lenses. S/E = the finest ground glass that you can afford with special coatings on the lens. Budget = no weather resistant cameras. S/E = Water proof, and impact resistant, and the camera cannot be moved with a stick, or a mop. Budget = sacrifice the distance view, and gain peripheral vision. S/E Sacrifice peripheral to gain zoom on the object, (add more cameras). Budget = plug, and play. S/E A well thought out plan, a well thought out design, a well thought out install, testing all equipment before an install, testing all of the equipment after it is installed, and an after install comparison to the specs, and design. Did you build it to the specs, and does it match the design? I would always recommend hiring someone to come out and design, and install your video surveillance system. You will wish you hired someone when someone gets a way with a crime because there was not enough information in the video to go beyond all reasonable doubt in the court of law. ( OK so maybe he hired a million dollar lawyer, and pleaded down to a lessor crime). _______________________________________________________ If you are buying budget entry level IR cameras make sure you buy cameras that have IR distances that are double the distance from the camera to the area you will be watching. 30 foot IR cameras are common in the USA. You are looking in to your yard about 10 feet from your house, or so. This will illuminate an object, or a person. The farther you go the better your camera needs to be. Get ready for some fun!

Will you be adding a fuse block to the power supplys?

Are you using a PC based DVR, or a stand alone DVR? I thought you would have a composite video out?

You are absolutely dead on target! I have this problems just standing at my counter trying to prequalify my customers, and trying to find who are the tire kickers, and who will go to the big box warehouse to buy their stuff. I do low budget enty level projects, so I do not lose to many customers. I am more interested in customers. The more numbers that come in the better my odds. The Spy Shop brings in the curious, the gadget shoppers, and from there I gain extra customers for surveillance. The condition of the shop is really in bad shape. The carpet is worn, the displays need some pizzaz, the ceiling tiles are sagging, and it does not look very professional in my opinion! I am going to build a little area in one corner for small children. This will keep them occupied while mommy, and daddy talk to me about keeping the boogy man away! Have you ever been to Disney Land/Disney World? There is a lot of "eye candy", and lots of energy! There is so much sensory overload. I want my shop to be the standard for a 75 mile radius. I just started advertising in the next county because I get customers that come up from there. I do not want to drive an hour to each customer to do a Dog, and Pony Show! If they come to me, I can give them a quick tour of products to see what is in their interest, and what is best for them. I have a project going on in North Carolina. I am not going to travel there until he puts up a 50% deposit. I did meet him on his 20 acre parcel of land here locally, and we measured off his propery, and simulated his environment. We set up cameras so that he could see what it looks like to go 500 feet with a zoom lens. When we go up to the smokey mountains he cannot complain about the video on the monitor. We pretested locally, then we will test on site, then we will do an install. It is much easier for me to show him around our show room!! ______________________________________________________ I want to set up two simulated remote stations with two computers. I want to use the talk feature of the Video Server S. I do not think anyone would use this feature, but it sure looks cool! Dog, and Pony Show! 40 people in a month, and if I can keep 50% I will be a happy man! Daytona beach is next!

How about a smudged photo copy of the Doc? Lets see $20 inner box, $20 outer box, $20 Bubble Wrap, Newspaper Free, Knowing that package carrier is going to smash your box to death... Priceless!!

Why would someone come in to a video surveillance showroom, and steal a wireless nanny camera? Why would you look at the 32" TV screen on display showing an 8 slot multiview, and not realize that there are cameras, and hidden cameras? Why would you stand in front of a 220X zoom camera while looking at products on display, while it is is zoomed in about the 50mm setting? When stealing a nanny cam, why would you leave the power cord behind? What? Are you afraid that this might "give you away"? Why would you assume that I am an honest business man, and not call the police to report a cheesy nanny cam stolen, and some very expensive DVRS? Oh yes! I think some PTZ were taken too! Am I up to felony grand theft yet? OK! You were smart enough to pay cash for your products that you did purchase!

Here is some quick info: http://www.9xmedia.com/Pages-products/2000%20-%20Xwall.html http://www.multiplemonitors.org/Pages%20-%20Hardware/Hardware%20-%20Multi%20head%20Video%20cards.html http://www.massedi.com/ http://www.perel.fi/pdf/TFT-Monitorwand_E.pdf Is this an installation for yourself, or is this for a customer?

I would recommend hiring a local company that can help you through the various componet setups! There is more to learn then what you can learn in a quick over view! If you are on a budget then click on articles at the upper part of your screen. There are some good "How to do" articles to get you started. Then read the section on security cameras, digital video recorder, and Installation help, and accessories, and video control, and transmission. If you have any questions post them here at this thread, and I will get back with you. I hope you enjoy the articles!

Are you wanting to put up a screen, and send the video through a projector to create a large display? Do you want multiple tvs stack side, by side, and one on top of the other? These slim line monitors are very expensive. The computer that takes a video, and splits it up in to multiple monitors is very expensive, and you will want to have a residual income to make up for repeated visits back to reset the video wall. If you are asking what I think you are asking I would be more than glad to set you up. Actually I would talk you out of it first. How about 4 LCDs on a wall! This would be inexpensive compared to a whole wall. I would recommend a video wall more for advertising, such as at a car dealership, or for a tradeshow. These are great in nightclubs, and bars that show music videos! You have probably seen them in high end clothing shops! How can I be of service? Scorpion Scorpiontheater

What kind of cameras were they? Remind me to avoid them!

I am curious as to why you would have 13.5 ~ under load? If you disconnected all of the cameras what would be the "unloaded" voltage reading? Now I am really curious!

I commend you for doing an autopsy!!!!!!!!! You must be a member of the MENSA! Alot of techs out there would have not gone through the trouble! I have to say I am impressed! If you ever move to Florida, look me up!!!

When you measured the 13.8 volts was that under load with working cameras? I know you know not to measure straight off the power supply, I am only asking for those who may read this post, and do not understand that you have to measure the power with everything hooked up to it for it to be a good voltage measure! I do not think that a 13.8 volt 7 amp power supply will kill your cameras!!! The other question is why the protection circuit did not save the cameras? I think the power supply is bad. I think that once it heats up it injects AC in to the supply line. It could be that the rectifiers collapse when hot. It could be that there is a higher voltage then 13.8 and the regulator keeps it at 13.8, and then when it gets hot the regulator collapses, allowing the full voltage value to run straight through to the cameras. I am only guessing as I have never used this power supply. I would do the following: Replace the power supply. Use a fuse block. Check the wiring for possible shorts, or bad connectors. _____________________________________________________ Do you have a proposal where you recommended a power supply, or a different circuit then what they have. I am hoping that they turned down your proposal, and you can use this to get back at them. You can tell them "I told you so"! I hope it works out!

I am confused! What voltage were the cameras rated at? The extra voltage fried them? 13.8 volts? Sounds like to me you had a short somewhere! Was this a boxed power supply? I would have hoped that the fuses would have isolated that particular "circuit". If it was not a boxed power supply what kind was it? How were all of the power wires attached? Do you have emails where they told you that you can "plug them in you are fine"? Do you have it in writing? You don't? If you did you could make them pay for the new Proper power supply, and your added labor to boot! I really feel for you man! I guess it's a monday after all!

BAAAAAAAA HA HAAAAAAAAAAAAA! It looks like Eminem has finally hit rock bottom! Well, it looked like Eminem! This is not the first time they have smashed, and grabbed. Of all of the things to grab, they grabbed open items rather than boxed items. I bet the store owner will see them on old footage pretending to be buyers, and asking questions. Once they learned what they wanted, or needed they then came back and, stole what they needed. They would have grabbed boxed items if they were going to sell it or Ebei it.

Great find! I have a club in the north Miami area that is comiing up for an install, and I have run out of my minis!
