Design for 64 cctv cameras

[zainfakhan 0]

Hi,

 

I would like to design cctv cameras for a project.

There are cctv cameras to be installed on a boundary wall which is approximately 3 km in length.

The cameras are with coax and also require a power cables.

 

When I estimated coax length it comes to around meters of coax cables and same length for power cable. this is not economical as the price is going too high only for cables.

 

Is there any way to design the same system using Fiber optic cables. All the 64 cameras have to come and meet in one dvr.

 

If it can be done with fiber cables what parts will be required to install the system

 

Please help me in designing the same.

hi. if you think going coax is too expensive. then thats the end of your job. fiber will cost 10 times more. and if you have not used fiber allow a budget for mistakes. mains power over 2 mile is also going to be very expensive.

 

 

going to look at a job of that size and thinking coax,, is a problem in itself. cat5 is an option but you need power.

 

what is the total budget for this job. there is no point going into other options like microwave or solar power.

I know that the area to cover is long

You could have DVR's out in the field and networked together via fiber, wouldn't save that much though

Why not use encoders and a NVR with fiber?

[tomcctv 190]

because from 3 km far also i have to bring the wire to one place.

 

 

you do know you cant run power 2mile along a wall ???

 

 

with the budget you have .......... close on a million $. you could get a company in and still make money.

 

but i think you are not talking US dollar ??? are you talking Zimbabwean dollar ???

So what do you suggest for power cable??

And also I am talking about US$ & I am using a bosch camera & accessories.

 

Suggest me a solution please

I am using a bosch camera

 

 

hi. what model bosh are you using and what will you be using for recording.

 

 

 

you would be best posting a google image of the area you need to cover. also mark out if you have extra power along the 2m wall.

 

 

can you go underground with cable/fiber

Goto google earth and screen shot the area, use image editing software to mark out camera locations. Use the distance google shows to approximate your camera distances. Power far cameras locally, install a large weatherproof box if need be with an AVR. If there is another building you can power them there, optionally put a separate DVR/NVR in there and as already mentioned maybe monitor it all over the internet/network. This possibly sounds like a job for cat5/UTP transmission. If you want someone to design it just send your diagram with the distances and camera locations to a manufacturer like NVT and they will tell you which of their products to use.

Couple of ways to do it, all expensive.

 

Could switch to PoE cameras, and put a hoffman can every 150 meters with 120vac power, along with a power transformer and a network switch with multiple ethernet ports and a fiber uplink, then you're just running riber out to a can every 150 meters, and cat5e to each camera within 100 meters of either side of the can.

 

Second way would be similar, put a can every 150 meters or 300 meters with a power supply and coax to fiber converters, running fiber out to each can, bunch of fiber converters back at the head end to convert it back to coax. Something like American Fibertek or Comnet have what you need for the fiber components.

 

If the 3km is lighted, you can mount the boxes on the light poles and pull power from the light poles, but you'll need some type of step down transformer.

 

Bottom line is it'd be a star configuration to minimize the amount of cables running back to the head end.

 

 

Depending on the perimeter, you could also put multiple cameras in a single location with different lenses to cover a very large area... this would significantly reduce your cable.

Thank you for all your replies, I will think over it,
