security problem
we have a problem with thieves.
its on a small block of 24 acres with 2000 mango trees on it, ( keit variety ) value of this crop is approx $40000.
being a late variety mango, everyone was away from that block for about 2 weeks, when they went to pick the fruit they were gone.
what i want to know can it be protected by cctv cameras 24 hrs a day, also what type of cameras ( infrared ? ) and what has to be done to install these ?

the idea is to see who is knocking them off, an alarm wont be any good as nobody lives on the block.Originally Posted by Grudge
Mango
There are so many variables
Does the block have any lighting
Is there a a shed with power
Is there 3g access
Is the block square give me an idea of size or send me Google earth picture
Don't think led illumination will be any good too far
I am setting up a PTZ camera next week with low LUX to do a large site will send you the logon info and you can have a look and see if that is what you are after
If that is what you are after will point you in the right direction
1 no
2 yes
3 3g ( if thats mobile phone ) yes
4 200mtrs x 400mtrs approx
Be aware that there is no commercially available CCTV system which cannot be defeated by a hat and sunglasses.
You also need to protect against someone attacking the cameras.
In addition to evidence capture, you may also want to think about a number plate capture camera in a discrete location as I assume they'd be travelling in their own car.
Finally, as silly as it sounds, some signage advising of private property and encouraging others not to steal. It's amazing what people genuinely think is 'fair game'.
Hard to give useful info without seeing the exact site setup however...
Rather than just CCTV you may be better off investing in a monitored electric fence with a couple cameras covering key areas.
Long as you keep the grass/weeds away the false alarms are very low and at least you would know when someone entered your property and not after the fact. The couple I have been involved with were about 1.5m high and installed a meter inside the boundary fence. Don't know the cost as only did the security panel side.
Only issue is if your local council will approve it.
Trying to cover the block boundary with enough cameras for facial recognition would be a very expensive setup. PTZ won't do you much good since none to watch it.
Depending on how much detail you were willing to settle for might be looking at a pole every 100m with 4 cameras. 2 cameras facing each direction and covering about 25m of the boundary each.
Decent IR lights are not cheap, ie the raymax 100 is over a grand from memory with a 10yr quoted life span. To get even coverage 2 minimum per pole and probably find need a raymax 25 to light up closer to the pole.
Edit:
Dan has a good point about the hat too, at the same time you would be suprised at how often people walk straight up to the camera and look right into it before they try and break it.
Edit2: Something else I have used at some wineries is 200meter PE beams ie hooked to a alarm system. Long as you don't have too many animals ie roos to set them off.

Maybe beams around property with air raid siren and gsm monitoring. To cover those distances with cctv could cost upwards of 2 crops.
Sounds like a job for a videofied
2Secure, weren't you the guy someone install a Smoke Cloak in their house?
It seems in a mere 3 posts, you've gone from completely Over The Top, to the total opposite end of the scale.
Read the original post. The property is 24 Acres.
That's 97,128 square meters, give or take a few mangoes.
How many of these, do you reckon he'll need?
Maybe he should bury a couple of as well?
Ahem.
Now more seriously, "Mango", I've been doing some casual research into orchard and agricultural theft. I don't know what area you're in, but it would also be worth speaking to the local police and neighbours as well as the relevant Department of Agriculture. Short of leaving a caretaker on site, this problem is going to be harder to solve than a few cameras. Sorry.
Whilst technology is fine (and I recommend it), you will also need an integrated approach involving law enforcement and advice from previous victims to profile the thieves and identify steps to ensure you aren't a soft target. Assuming you have some manner of electronic detection, you will also need to be able to ensure that any response is timely enough to either catch them in the act or convince them not to try. Planning this ahead of time, e.g. with the local police will make this easier (again, depending on your area of which I'm not advised).

the police dont do anything, its like talking to a brick shithouse, been there and done that.
we are not a small farm, that is just 1 block of many, there are a lot of small farms been wiped out, by these pricks.
they come on full moon nights and nights where there is good moonlight, they can clean 40 acres in 2 nights.
i know who they are, all i want is to see them on camera, i have a year to wait to see if they hit us again.

Well maybe Mango could put some smoke cloaks in to cover the mangos while he is at it. What do you recon? But they might not work too well seeing as though its in a field.
Now more seriously
It appears that the mango crop is located in a area that is 200mtrs x 400mtrs approx as stated by mango.
Is this the case Mango?
So the block maybe 24 Acers now why would you try and cover the whole block if the main target is the mangos?
If these guys know what they are doing why not just take the DVR while there at it, then that will leave mango with no video footage of who was there. To setup up a NVR/DVR that will remotley store all the footage would cost a lot of money.
Seeing as though videofied is all wireless (easy to install) and sends all of its video alarms to the control then it will make it hard to remove the evidence. But the issue would be getting someone to action the videofied alarm in a timely manner. It would be a lot more cost effective to look at a videofied solution before going down the path of a full blown CCTV setup.
Everyone has suggested covering the mango's. The fact the whole crop is being stolen suggests either a truckload leaves the site or a few trucks, either way. It would be far more cost effective to cover the access to the property rather than try and cover the entire property. I would be looking at discretely mounting overt cameras with sufficient night capabilities and possibly megapixel (afterall we do want to see the driver of the truck). As for DVR/NVR, motion event triggers can send snapshots via email offsite, who cares if they steal it.
As for the videofied solution, 4KB (220KB / 50 frames) snapshots are hardly enough resolution (320*240) to positively identify someone unless they are in point blank view of the camera, which means you'd need one per tree. This solution is only useful if the response time is sufficient to catch them in the act.

Video resolution of 320 x 240 pixels.
Let's see.
Step 1: Install Videofied, at considerable expense mind you.
Step 2: Mangoes get stolen again, for the second season in a row, driving business to the wall.
Step 3: Discover Videofied wasn't actually suitable, like me and George said.
Step 4: Install another system, at considerably larger further expense, wholly writing off the earlier expenditure and hope like buggery it works for the third season.
Yup. Cost effective indeed.
Mango, if the police are being unhelpful, it may be appropriate that you and a group of other victims organise. Ultimately police are answerable to the Government and your local member can be useful in applying pressure (read: resources) in the right place.
If you think you know who's responsible, I also wonder whether tracking the mangoes might help. I know that RFID technology is used to protect against animal theft (the cow swallows a device) and I wonder whether there is a fruit-based system. Worth looking into as long as you have a suspect. I don't mean to insult your intelligence, but I'd be checking to ensure the cops realise you are talking about major organised theft, and not someone nicking a few bits of fruit.
George expanded on my point in relation to number plate capture. Is the theft occurring at night? I don't know much about mango farming, but I think a few signs along the road saying "report suspicious activity - call xxx" might also help. If anything they will establish you as a hard target, and encourage the thieves to steal someone else's mangoes.
Just be careful. Fruit can be a dangerous weapon. [ame="http://www.youtube.com/watch?v=4bCyIAsSid8"]Fruit as a Weapon[/ame].
