Anyone has any taughts or ideas to share on a CCTV system for a fast food store?
I see Makro has DIY Vivanco systems?
I dont intend on advertising, but the systems you are refering to can be done in PC or Embedded based... Here is a bit of advice though... Forget about the units sold at macro and builders and so forth, there is no support, quality is matched by price and you arnt going to ge anywhere near 6 weeks of recording as those units work on 250GB IDE drives, IDE is not available on the market anymore and the recording compression is not great...
You need a specialised system that you know you have backup and suppotr on and atleast 1 - 1.5 TB worth of storage space.
IDE Hard Drive based systems are slower than SATA based systems, which affect video quality. They're also outdated and replacement spares (especially the HDD) could be hard to come by in 2 or 3 year's time. Many PC suppliers may still stock IDE HDD's but some of the larger suppliers don't have them anymore.
The advantage of a PC based system is that you can add more channels later if you need to. BUT, you'll need a nice fast machine with decent RAM (4GB to begin with). CCTV cards can be added, as long as you have extra PCI / PCI-e / PCI-x (depending on the cards you get) slots you have available.
I run 3 bullet type IP IR Wireless cams with motion detection in our complex. ( Quite a bit of traffic) I can get about 8 weeks on a 300 Gb drive.
What I have learned though is that if you record video as opposed to snapshots it uses your HDD quite fast.
A typical motion video ( AVI ) file is about 2 to 10 MBs as opposed to a series of snapshots @ 15 to 20 Kb / each snapshot. ( Depends on how long the motion is detected. )
Snapshots can be set as well, to say 6/sec or 10 to 15 per minute...........all depends on what you want.
Google the following software program and check it out: Active Webcam v11.5
Just a tip............do not download from PY Soft site directly, the download does not run all the way. ( Program is free but you require a license to remove pop ups. )

You may never know what results will come from your actions, but if you do nothing, there will be no results... Rudy Malan † 05/03/2011
Word of advice. Get a demo on a similar setup to what you decide on. Chances is that your expectations is going to be higher than what you get. Facial recognition is very important. If you can not ID a stranger, it is useless. To ID workers is easier, as you know them, but someone else, looking at the footage, might argue. Then, frames per second. If you want to see the exact action, make sure you get 20fps at least, not on paper, but in reality. IP based systems is notorious for lacking in these aspects. The specs is great, but the network can kill it.

I have done quite a few of these systems - I use a 4 channel or 8 channel embedded system with good camera's - I stay away from IP stuff - but they do have their place.
Makro has cheap and nasty equipment - my advise is to stay away from that sort of equipment - its exactly that - cheap and nasty and does not last very long !

IMHO, you raise some valid points! It's noteworths that in the recent cases of police brutaility at shebeens, those shebeen keepers had good cctv systems in place, as it captured the events very clearly and one could positively indentify the perpetrators from their footage..
been doing some research into cameras and setups...with my limited knowledge...what i can share...is that it is all about planning...the better you plan the better the outcome.
what i mean by this...
there are specific applications for each camera...you need to know what you expect of the camera...do you just want to see something happening or do you want to identify people...numbers plates...etc...while recording...will it be recording during the day and if at night will will it be in well lit areas...the distance from the camera to the location...etc etc.
yip you can set the camera to record in specific pixels...ie...if you have a computer on a table in a room and dont want to sit watching hours of recording you only want to see if anyone touches or uses the copmputer...you can set it up to record only if there is movement in those blocks on the screen.
i have cameras setup at home which i am using to experiment...using a dvr...and found that you cannot setup motion recording out doors there are just too many variables...and lots of bugs which seem to love the red lights.
if you want cameras for a specific application...makes sure you plan and spend the money on the correct setup...otherwise dont waste your time or money...make sure you get someone who knows what they are doing as in all industries there are lots of so called specialists...one of my customers learnt the hard way...so now i am busy trying to clean up the mess...at least one good thing has come of it... cameras setup in the lounge...and a screen behind a secure passage door...would work great if we have an intruder...you could line make up the intruder and plug them without them even knowing you can see them...and if there is more than one you would be able to see where they are and how many there...just dont shoot them thru the door otherwise i do beleive it would be classified as planned...wouldnt look good in court.

Jip, criminals got the law on their side. So I see them running up to the house. One hide in the garden, another around the corner and one ring the front door bell. All three has guns, but the one at the front door hold his behind his back. Now I observe all this on the cameras. The other two disappeared and is out of view. Behind the house and can break an entry anywhere. I phone the police. The one at the door gets agitated and start breaking a window to gain entrance, or even trying to kick the door in. I am not allowed to shoot, because it will be interpreted as planned? I must wait till he is in the house and then determine what his intention is? Maybe he just want money and a TV, or a glass of water? You can not give someone the death penalty for that! These guys is professionals. Your life is never in danger, as long as you give them what they want. You can always claim from your medical aid later, get antiviral pills for the wife or daughter, replace the TV, work for some more money, get to see a psychiatrist... And do not forget! You will have footage to entertain your family and friends with! Because it will be useless as evidence. I experienced that. Got them on tape, breaking into my sons bakkie and take his R12000 laptop he forgot in the bakkie. The answer is simple. There is millions of them. Where must they be found? And they all look alike...
considering pepper spray for that side of the house...there are systems installed in sub stations and pump stations which are activated by sensor...i am planning on doing some research to find out if it would work...how dangerous it is for my family and what the reaction would be of the would be lost person looking for a glass of water...breaking in thru the window or nowadays straight thru the front door.
