found 5 american dynamics cctv camers and want to add them

[halsaps 0]

Hi I have found 5 american dynamics cctv camers where I work and want to add them to my system is it easy for a novice to do I need to know what cable i would need and can i spur off power that is already near to where the cameras and are they easy to add to the software. they are a dome type 540tvl are they any

good they are pal 3-9 mm VR Discover i would be grateful for any diagrams help list of wire cable needed.

where can i get the cable from is available in b&q

hi no not from B&Q. you will get everything from City electrical factors. you can do it with either cat5 or coax. how far will the cameras be from your dvr and do you have mains power near to where you are installing your cameras ???

Hi halsaps. Just checking the obvious - are these cameras using the PAL standard, or NTSC, and is this match your home CCTV setup? It's just that you mentioned that they are "pal 3-9 mm VR Discover", and I don't know whether you are in the US or not.

As to whether they are good camera, any camera that is free and (sort of) works is a good camera

Hi Yes i am frolm eseex they do say pal on them and there is power nearby some of the runs of coax will have

to be quite long as the store is quite large this will affect the image wont it.

Excellent! How long is the cable run? With good quality coax, you can get some decent distances. Have a look at the Pelco document here: http://www.vfmstore.com/choosing_correct_cable.pdf which will tell you everything you've never wanted to know about the different types of coax you'll run into, and what distances you can get. Note the warnings about cable TV (CATV) aluminium braid, steel cored cable. Best to stay well away from that, and use good quality copper cable.

 

Alternatively, you could use baluns and twisted pair wire (Cat5/ethernet). It can work out cheaper overall, depending on how much cable you need. An interesting document to read is this one from MuxLabs http://muxlab.com/assets/files/application_guides/VE_CCTV_Balun.pdf

There is a risk of ground loops (well, more of a risk) when using twisted pair, but this shouldn't be a problem with your cameras, as it is very likely that they internally use an isolated power supply which will prevent this.

 

Anyway, that should be enough there to get you started...

thanks for your replies that is very useful. this is my works cctv as it would be nice to catch more of these

petty thieves and i don't have to do so much patroling.

So to make it easy for me i can spur off the power that is already there which i have from other

cameras near to where the new ones and the actual image i have to run a coaxial cable from my box

to each camera which is a bit of a pain you help is v v much appreciated.

It might be possible to spur off the power, but it depends on several things:

* On how generous the installer was with the power cable. The main problem with spurring is that you'll increase the voltage dropped (lost) along the power cable. If the cable is heavy enough then no worries. However, if it's of too small a gauge then the voltage drop could be too much, and there won't be enough volts to power the cameras.

* You might also draw too much power from whatever is powering the existing camera. Do you have a central power cabinet, or a lot of wall-warts plugged into a power strip?

 

I haven't had much luck finding info about the American Dynamics cameras. They want me to register to gain access to the manuals. From what I can make out, the camera probably works on 12 or 24 volts? Do you know?

 

It's usually less hassle in the long term to run the power lead when you put in the new coax. Light weight speaker cable is fine; it doesn't have to be fancy. You can also get siamese cable that combines both coax and power in the one sheath. It looks very smart and professional, but costs more. If you use the CAT-5 cable, you can carry power over the unused pairs, so you only have to run the one cable. However you will need to buy a pair of baluns for the video.

 

What sort of distances are you thinking of? Shorter distances make spurring more practical, longer distances are more of a problem.

around 100 - 200m at worst

says they are a tyco company don't the make kids remote control planes.

has a pixim orca sensor. thanks again for your help

oh and on the little maual it saysa the camera is either ADCIEH/ADCDEH/ADCBEH

HI RES 540 TVL OR ADCW/ADCBW HI RES WIDE DYNAMIC RANGE 504+TVL

NOT SURE WHAT MUCH OF THIS MEANS

tyco company

 

 

 

hi tyco are good cameras. sold in the uk by honeywell.

 

 

for 100 and 200 meters then i would put in a dedicated power supply or seperate power at each location. also for that distance i would use cat5 with baluns.

[halsaps 0]

the ones we have are ADCDEH 0309tp opened one up for the first time saw to connections 1 the balun one is the other one connected up to anything where is the the cheapest place to buy basic baluns and what do i type in to find cheapest so far is £1.49?

for £1.49 look to see if it is a balun. Ebay is full of these and there calling them baluns WHICH THERE NOT.

 

 

THIS is what you need to look for.

thanks that looked very important to know. know i need 12 as i have found another camera that

i am hoping just renewing the coax to the video recorder

[halsaps 0]

got them ordered just got to wait till they are delivered. any help on siting these

cameras would be most apprecited

Hi anyone know once ive done all the cabling and put the power to them and connect them to the recocorder
