Hi,

We are going to have to install security cameras at the complex in the near future. I estimate in the region of 16 cameras, minimum.

What are the capabilities of the devices, what does one look out for, etc?

Thanks
 
Whew thats a really tough question.

I would say minimum of 600TVL
Good day / night capabilities
Something with a good DVR preferably full D1 on all channels

Be careful, cheap = crap

600TVL is the resolution. The distance depends on the lens size.

I agree with marine on his suggestions.
 
Expect to pay around R 950 for a 600 TVL outdoor dome camera in a watertight enclosure. I am using Paravision prices as a guide
You will need at least 4, 5 amp 12 volt power supplies at about R 350,00
A 16 channel DVR with a 2 Tb hard disc is about R 7500,00
Co-ax cable, hardware and fittings, add about R 4000, depending on the distance
Then an installation fee of at least R 10000

So if your budget is R 50 000, then you will have no problem meeting that figure

A 600 TVL camera with a 4-9mm zoom lens will resolve facial features at 20 metres
 
get a professional in who specialises in surveillance. Depending on the layout planning you might not need as many as 16
 
Complex is 4 stories high, is built in "U" form, quad area between arms of "U". Stairway in bend of "U". Fire escapes on the legs of "U". Walkways around 30 meters.

Will Google some more while I start drafting a requirement/spec sheet .

We managed 8 IP-cameras and server (including cabinets) installed for under R50k - but this was with 6 guys from the community rallying together to do the installs themselves - with the relevant expertise. Benefit to IP cameras of course is that you can access the cams remotely with viewers on phones, etc.

What are the Pros/Cons of Coax vs IP?

Live in a 11 floor flat that is considering cameras.

Biggest pro from our install was being able to send data wirelessly - we are a village with 200 houses - cams are on the perimeter.

IP cams are about 2 to 3 times more expensive than normal cctv.
But in your case you may save the extra by fitting switches and using IP cameras.(you would not have to wire every single CCTV cam with coax)

A major consideration here is the key differences between co-ax/analog and CAT5/IP: on co-ax you're running an analog signal that is subject to degradation over distance, not to mention that the cable often used is called "powax", a contraction of 'power' and 'co-ax', which is nice and expensive per metre. An IP system would use CAT5, which is available approximately everywhere and has a known signal run per segment of 100m. Also, being a digital signal, you get no signal degradation over even that extreme distance.

And that's before you get into other factors. :p
 
The only advantage, I can see to wireless IP cam's is that they can operate, over a longer distance, and at possibly higher speeds, but then if you connect coax cams in cells, that each have their own AP, you can achieve the same result, in some instances, this might be preferable, like not having to junk, older, already existing infrastructure ... , which is still worth using ...

IP cams can offer much higher resolutions, obviously at a higher cost. also as mentioned it can be sent much more easily and effectively wirelessly.

Also note that you are able to convert existing infrastructure into IP, either by converting a normal analogue camera to an IP output or actually running an IP camera over existing coaxial cable etc.
 
Why can people not make proper quotes ... <sigh>

Then they wonder why they do not get the work they quoted on ...

This is what I asked to get quoted on, if this equipment could not be supplied, equivalent must be quoted on with specs ...


1 x AVTEVH 16 Channel D1 DVR
1 x 2 Terrabyte Hard Disk Drive Seagate
1 x 21.5 Inch Wide LCD Monitor
1 x 16 Channel Regulated PSU
1 x 1/3" SONY CCD 40M IR 6-15 52
4 x 1/3" SONY CCD 600TVL 40M IR3
9 x 1/3" SONY EFFIO 600TVL 3.8MM L

DVR must be D1 capable on all 16 channels.


This is a quote I just recieved ... :(

1 Provision 24 Ch DVR, 16ch Audio
1 18.5" LCD Screen
1 1 Terra Byte Hard Drive SATA
14 IR Bullet 35m 600 tvl 4-9mm
1 Provision 16 channel 12 amp
4 RG 59 With Power 100m
28 BNC Crimp 6mm Normal
14 DC 12V Pow er Cable and plug 21.m

Looks like a Makro kit installation ...
