Is Cheap Video Surveillance Possible?
timholman writes "After a series of burglaries and auto break-ins in my neighborhood, I'm thinking about adding some video security cameras to my home. To me, the object isn't just deterrence — if someone tries to break into my house or my car (parked on the street in front of my house), I'd like to provide a high-quality image of the perpetrator to the police. Inexpensive video surveillance systems, with their atrocious image quality, are nearly useless. The problem is being able to get good image quality at an affordable price. After some research, I've decided that using network cameras to FTP images to a central server over a HomePlug network is the best solution. However, good megapixel network cameras (e.g. Stardot or Axis cameras) can easily cost more than $1,000 each. Has any of you dealt with a similar situation? Is there any way to get reasonable quality (preferably open source) daytime and nighttime video surveillance equipment for home use without paying an arm and a leg? Is it better to go with a couple of expensive cameras, or a multitude of inexpensive cameras? Is paying two to three thousand dollars simply unavoidable if I want to monitor my front and back yards?"
I've been working with IQinvision's IQEye 511 camera (www.iqeye.com) for the past couple of months. It is a 1.3MP camera capable of 15 fps. It communicates over and is powered by 100mbit PoE. I think the street price is somewhere around 600-700 dollars, depending on what you get with it (PoE injector, lens, etc). The camera seems to take pretty good pictures and can deal with pretty varied lighting conditions. It has various ways to retrieve images, like emailing or ftping them to you on a set schedule. Hope this helps.
Get a dog. The TCO may be higher than the camera, but the deterrence factor is way higher (and it's better to not be broken into at all, than have footage of your breakins afterwards).
I sat on a grand jury a couple years ago. (Not an investigatory one; we issued general felony indictments. The county I live in does things a little oddly -- they have a pair of standing grand juries, each of which meets once a month to hear potential indictments. You're on the jury for a year, and hear a couple dozen cases each day, so I saw a bunch. All felony indictments go through one of the two.)
The most common case for small time burglary was that there would be a set of crimes that the police were convinced were related, and then finally the thief would hit some place that had video cameras that were placed well enough to produce a usable image -- at which point, odds were they had already had dealings with that person, and the case got fairly easy. So usually they would present it to us as an indictment for just the one crime, but explain that the investigation was being treated as part of a group.
So if you want the guy caught, there's really no substitute for good video surveillance. Sure, plenty of cases were based on things like the thief pawning stolen goods, but video was the most prevalent and easiest to work with.
Tell the local FBI office you're thinking of opening a Taliban mosque and they'll keep 24/7 high-res real-time video with CD quality audio of your entire property with an emphasis on identifying anyone coming or going. Then if anything happens they'll already have the suspect's name, address and phone number on record. Just ask the police to get the info from the FBI.
You need to get yourself a dog. It doesn't have to be big or scary looking- a small, yappy-type dog will do just fine. Unless you advertise the presence of valuable goods inside your house, a burglar will not break into your house if it is occupied. I think you'll find that most burglars will go for the lowest-hanging fruit, which will be your neighbor's house (unless they also have a dog, in which case the next house over is the low fruit). They want to get in, grab the stuff that is easiest to make off with and pawn, and then get out. I doubt you have any state secrets or anything like that in your house; this is a simple cost/benefit analysis for you and the burglars.
Another thing to look into is a neighborhood watch program. Of course, if you live in a neighborhood like mine that might not be a viable option. In that case, you need to get yourself a dog and a steel-core door. Skip the expensive cameras. Are they really going to save you money? Or is this a vindictive side of you, the side that might put a "Trespassers will be shot. Survivors will be shot twice" sign on your fence?

No offense, but I've stopped responding to AC's.
Actually, quality isn't the issue. Angle is.
What you need to do is ensure that you capture a face shot as close to eye-level as possible, without having the camera obstructed by people walking by.
The police and FBI don't like to talk about it, but there is a program where if they input a digital photo of someone, even a poor quality one, the computer will compare it against the database of digital photos taken by the Department of Motor Vehicles and spit out the six closest matches.
These system rely on facial characteristics like eye-nose-mouth ratio, hairlines, etc so as long as the computer can accurately calculate the centers of these areas, it works.
But when cameras are mounted up on the roof or in a corner as is typical, they are worthless unless the suspect looks right at them.
Also, you want to think about having a camera just for vehicle traffic on your street or culdesac. A license plate is going to be your best method for apprehension. Sure, the car may be stolen, but if it is recovered then it can lead to your property. And if it happens to be a crime of impulse, you will have a suspect.
If you were really clever, you could find some way to rig a standard digital camera with a flash similar to a red-light camera. This would be your most inexpensive option but also a dead give-away and not recommended for busy roads. Instead, find the least expensive camera that offers changeable lenses, and then focus them on a spot on the street that you know vehicles must drive through. Add some inexpensive infrared lighting and you should be able to playback a log of all vehicles (suspects and potential witnesses) when there is an incident.
I think having more inexpensive cameras with decent quality will have a greater chance of success than a couple high-quality ones. Also, don't overlook physical security sensors. Infrared beams and even motion sensors are the best way to deter the crime, instead of relying on catching the criminal.
I have been on the victim side of countless incidents in my profession and, frankly, you won't get the time of day from law enforcement. If a light turns on, or a camera flashes as someone approaches your vehicle...they will move on. And don't forget if you are worried about your vehicle and not just what's in it...pick up a used Sprint/Nextel phone on eBay and split off power from your car's 12V plug. Hide the phone inside the dash somewhere on continuously. Get the least expensive plan, or just write down the IMEI so that you can later activate the phone by calling Sprint. If the car does get stolen, activate service and add-on the GPS tracking features.
Cheapest Lojack you will find.
Good luck.

There is only one important reason to have video surveillance. I've got a camera outside each entrance to my home -- four. It's not as a deterance. And it's not for security. And it's not to catch the thief.
It's for one thing and one thing only -- insurance. It's really easy to make a claim when you have video footage of someone stealing your stuff. That's it. It doesn't need to be a good quality picture at all. It needs to show a humanoid holding a television.
There are, of course, gravy tastes. Most insurance companies will give you a small discount for having such video. Also, when the cat got out (movers left the basement doors open after they'd left), watching eight hours of video at 16x speed allowed me to figure out that Snickers had crawled into a furnace vent. She came out when we turned off the flow of fresh air.
That solution won't save money. Do you have any idea how much it costs to train a dog to safely and effectively handle a firearm?
Steps: 1)Go through the list of cameras on the above site, and select one that has the specs you want (good resolution, zoom, etc.)
2)Check eBay or find a used one.
3)setup software and install camera where you want it.
4)Enjoy cheap but hi-res image security.
Many of the cameras on the list above go for less than $100 in good used condition, and offer many megapixels and good optical resolution. Many of them also have other features like low light mode, or other things that can be controlled by computer software. Good luck!
