the toss

1) You have dual voltage cameras - you should have opted to run at 24Vac as there is less likelyhood of voltage related problems. (voltage drop issues & earth loops)

2) Your cameras AND DVR are both TVI - have you checked. TVI cameras running on analogur DVR can do weird things but you will usually get "some" kind of picture

3) You say you are getting no picture but what ARE you getting. If it is a "black" screen then there is no camera signal at all. (dead camera , o/c cable , no power etc) If it is a "blue" screen then you are getting camera sub-carrier but no picture information ( faulty camera)

4) 16.3V (on load) at camera is too high. That is 30% nom overvoltage. It would seem there is no voltage regulation on your power supply

I think your first step should be to get the operating voltage within spec and go from there. It could be causing all sorts of issues from thermal shutdowns to IR & exposure problems

I guess the main problem here is that you dont have a concept of consequences and they dont come into your thinking. I encounter this stuff all the time so dont tell me it doesn't happen. As the old saying goes " you can lead a man to knowledge but you cant make him learn"

I am finished on the topic but I hope the OP will see common sense.

The previous scenario I laid out is not so far fetched as you seem to believe and indeed most neighbour disputes develop along those lines. I made it simple for you to understand. I shall simplify it further.

There are cameras pointed at his house & he's not happy. He doesn't know what the cameras are actually showing and for that matter doesn't even know if the cameras are working. He wont take the normal first step of discussing his concerns but instead turns to the internet for advice about what to do.

If this develops to the extent of legal action taking place ( & the chances of that is at least 50% if he follows your advice) I can picture the judge saying - " so you were unhappy with the cameras pointing at your patio but decided not to discuss the matter with your neighbour. Instead you mounted floodlights pointing at his house on the advice of your internet friend Al Drake. How did you think this was going to solve your problem ?"

Everyone in that coutroom will be rolling around on the floor pissing themselves

The OP has NOT indicated he was only interested in technical advice. Indeed he has specifically stated "ANY advice appreciated" For you to think the first step in resolving this issue is to shine bright lights back at the neighbours house is lunacy. Surely you can see how this "might" pan out.

Neighbour 1 - That guy next door seems to get a lot of sus people meeting on his back patio , I think they are dealing drugs. I'll turn a couple of cameras that way just in case.

Neighbour 2 - That guy next door has aimed a couple of cameras at my patio. I could go ask him to move them but I wont. What I'll do is shine some torches back at his house - that will show him.

Neighbour 1 - What is that dickhead doing shineing lights at my place 24 hr a day. Maybe a couple of loads of dog turds over the fence will show him I'm not happy.

Neighbour 2 - That moron next door is throwing all his dogshiit over the fence. A flat tyre or two will show him not to mess with me.

Neighbour 1 - I know it was aasshole next door that slashed my tyres. Lets see what a screwdriver will do to the duco on his car.

AND on and on it goes - not an unreasonable possible escalation

OR it could go like this-

neighbour 1 - something odd about that guy next door & all his dropkick mates. He cant even manage a hello when you see him. Wouldn't be surprised if they are dealing drugs. I think I'll turn a couple of cameras that way just in case.

neighbour 2 - Never particularly liked that guy next door , he seems a bit weird and now he has a couple of cameras pointed at my back patio. I'll swallow my pride and go front him about it

neighbour 1 - (feeling a bit sheepish about being confronted) Ah well they are not really to watch your place. I could probably adjust them a bit so they dont see your patio so much but I still want them to see that area of my yard. I'll see what I can do & get you over to take a look to ease your concerns.

neighbour 2 - great stuff - thanks for that. Having my mates over for a BBQ next Sunday. We get together & talk football , why dont you come over.

Now the thing is that it might not go like the second scenario but I think that initially the opportunity should be approached because it is certainly the better outcome. To advise such a provocative response as shining lights back at the neighbour before ANY other response would be a bigger problem than the problem. If it got to legal proceedings the lawers would have a field day.

Bright narrow beam light = laser by most peoples definition.

I will repeat myself by saying I have seen hundreds of cases like this ( probably close to a hundred per year ) and it never fails to amaze me that the easiest and most logical first step is not taken. You admit you haven't talked to him.TALK TO HIM ABOUT YOUR CONCERNS. If you get no satisfaction then look at alternatives.

I'm sure your neighbour didn't just wake up one morning and decide to see if he could pss off tja.

@ Al Drake if you cant see how these things escalate to a war-like nature then you need to think again. Both sides have a storey and both sides believe they have a grievence and both sides believe they are in the right and both sides believe they are being provoked and so on and so on. Have a look at the mass shootings in USA and you will discover that it is usually trivial things behind the motivation

For someone to mount a legal case on the premis that CCTV will prevent a crime from taking place is akin to saying that no crime will happen because you have a Police Force. Of course if there is signage in the shopping centre implying or stating it is for the safety of customers then you could be in trouble. The best course of action would be to simply state that CCTV is in use throughout the premises and leave it at that.

Yep , shooting laser pointers back at his house is bound to ease the neighbour tensions. I've seen hundreds of cases like this and it is never about reconciliation but always about winning the war. Hope neither party has any firearms.

Depends on WHAT liabilities you are referring to. It may be that there is a regulative requirement to have CCTV as in the case of Liquour licensing and other high risk areas or there may be an insurance requirement for CCTV as in entertainment and other high patronage areas. As far as I know there is no requirement anywhere for real time response to anything captured on CCTV. HOWEVER if an insurance or legal firm smelt a dollar to be made .....well

It's only 2 months old - send it back to where you got it for a refund /replacement

You finished off your opening post with " ANY HELP APPRECIATED "

It seems that is not the case - only help that YOU want to hear is what you seem to want. This just reinforces my opinion that it may be a personality problem more than anything else. You are not going to solve anything by entering into an arms race with your neighbour.

Not every environment lends itself to useful employment of CCTV. In some cases major changes have to be made as far as layout & useage is concerned to get any benefit from CCTV. This seems to be one of those cases. Depending on what the CCTV is to be used for , maybe the focus should be on entry /exit points rather than overall surveillence

So you dont talk to these neighbours because of some things they have done yet it is them that feel they need cameras to check on you. I'm not taking sides I'm just pointing out that their storey might be a whole lot different to yours.

The situation is probably too far gone already when the discussion is only about retribution and not reconcilliation. If people would put as much effort into solving the problem as they do into escalating it everybody would come out a winner.

Some obvious questions come to mind. How do you know what type of cameras he is using and how do you know they have audio capability. Have you even approached him with your concerns. This is the first step on the path to a neighbour dispute when you have an issue but fail to discuss it for a resolution. If the neighbour's issue is with you then the dispute has already started. If it isn't with you and you happen to be just background viewing then by having a friendly chat about your concerns he may just re-aim the cameras and everyone will be happy.

ALL YOU HAVE TO DO IS TALK TO HIM

Stop replacing them with Swann cameras

What specs were the original power supply & what specs were for the replacement power supply

Are these pre-made cables or RG59 with BNC connectors?

Without knowing the specs of those cameras the following is just general advice.

Power Supply - allow 1A / camera ( so 4 cameras then a 4A supply )

Cable - Dont use pre-made cables. Run cat 5 & use baluns if the system is analoge

DVR - NVR for IP system or HDCVI/TVI etc if analogue

What you need is wireless AND POWERLESS

Hi. Your cheapest way is 24v to camera and then drop it to 12v

 

But for a gas station .... I don't think you are going to get much life out of that PTZ ..... 12v and it has IR it moves it also has wiper blade that is a lot of work for 12v

 

How many of those PTZ cameras are you fitting ?

 

total of 4 of them.

 

Is that so? How long do PTZ usually last? Both 12v and 24v.

 

These PTZ's will be moving 24/7 on a sequence.

Boy oh boy isn't that going to chew up your HDD space

@ Tom the 24Vac cameras have a built in regulator that does just that.

There is no single answer for your question - it all comes down to the components used in the manufacture. The general voltage tolerance used to be anywhere from 20% to 1% depending on the component quality which you are not privy to. As far as the designer is concerned the tighter tolerances the better but that is not good news for you wanting to supply overvoltage to compensate for your poor installation design.

The most obvious result of running overvoltage is excess heat but you could probably get away with running up to 14V.

The very reason they make 24Vac cameras is to compensate for long cable runs and this is what you should've used in the first place

You fail to mention THE most important parameter - the distance from the camera to the subject. The basic setup for gas stations is numberplate capture on entry AND exit as well as broard overview of the entire forecourt. After this has been established you may consider cameras viewing specific pumps and/or areas.

Maybe a design feature of Swann ???

I'd be careful about putting it right at the corner. You may have cabling access problems because of the jack truss timbers especially if it is a dropped eve

Maybe it wont be black OR maybe it will be mounted in the shade OR maybe it will have an internal fan.

It was a general broad spectrum question to which a general broad spectrum answer was given

There is no problems associated with spray painting a camera as long as you take sensible precautions with protecting the lens from overspray. The warranty will be void.
