I have been asked to supply and install a camera on an existing analog system and could use a little help.
A little history: Outside of their building is Main Street in a small town, they recently had an island with a water feature / fountain constructed in the middle of the street. You guessed it, kids are putting liquid soap in the fountain. You guessed it again they want to be able to recognize who is doing this and turn the image over to the police
Like I said, its outside and the street gets blinding sunlight some days. Approximately 25 ft. from the building and lit at night and also subject to passing auto headlights. They would like to run it back to the dvr via existing cat6 and use baluns
I can’t find a name on the DVR so assume it’s the lowest quality like the existing cameras. I only dabble in cameras and have no clue if analog or ip is the way to go or what camera would do this job
How wide an area does this fountain camera need to cover? This is important because you note, "they want to be able to recognize who is doing this and turn the image over to the police". This will determine what resolution and or number of cameras you need.
Ok, that's fairly narrow. Even an SD analog camera should be ok over such a small area.
Things to make sure about:
Good IR - this area looks like its going to be fairly dim at night. I know you mention headlights but you cannot depend on their light to light a scene.
DVR resolution - if this is an old DVR, it might not support 4CIF, which would be an issue (at that point, I recommend upgrading to a new DVR, specifically an HD analog one, which isn't that expensive and would allow using HD analog cameras).
Distance of camera from fountain. If it is 25 feet away and you want a ~10 FoV, you will need a moderately long focal length which is not standard on entry level fixed cameras.
About the headlights, I was just giving everybody a heads up that head light may be intermitently shined into the scene.
DVR Its less than a year old but it appears as cheap as they come. I will do a little more research on the DVR . I didnt put it in and no one speced the materail and it appears the electricians used the cheapest materail possable
You may also consider a good white light illuminator instead of IR.
White light is visible to the human eye (where IR is not). If the area is visibly well lit it may, in fact, deter them from even attempting this anymore. And if they do, you'll still have good lighting on the target to capture the details of the suspect (assuming the lighting is bright enough and setup correctly).
Another possible advantage here is, if the scene is lit well enough with white light, you may be able to operate the camera in color (day mode) rather than B/W (night mode). That is assuming color detail is important/helpful in this case.
Anyway, just wanted to throw this thought out there.
Sonny, although a camera seems like a good idea here in your war against serial sudsers, there are a couple of reasons to be cautious.
If camera is to be used as a deterrent, camera may become a victim instead.
Soap delivery can be effected from afar hand grenade style or from moving vehicles, complicating identification.
1. Pre-treat the fountain water with a non-toxic phosphate removing product like Sea Klear.* Although the soap will still need to be flushed, this will take all the fun out of sudsing by drastically reducing the effervescent effect.
2. Have a sacrificial cheap/dummy camera, mounted low, between the good camera and the target. Install a snip loop.
3. Use elevated vandal proof dome camera(s) for the money shots.
*Disclaimer, I have not deployed a phosphate remover myself, like Brian my experience comes from youthful activities inside the basin, aka, in the 'paint'.
Assuming the dvr is very poor, getting a low light b/w, something like I suggested, $100 online, likely has better resolution than the dvr. Have them buy that online, help them install a cheap solution. You're then set to help them consider a better solution, and I'm sure this forum will help with that challenge.
Follow up. I would have do this sooner but I have been slammed with work
The customer said just put up any camera so they could show due diligence.
I got a cheapo from amazon ( HD 1.3MP CMOS Sensor 1000TVL 9-22mm Long Distance Varifocal Zoom Outdoor IR-CUT Security Camera ) for 64 bucks
It did the trick, I wish the IT guy sent me a better screen capture, anyhow
Colls Fountain 'Soapers' Charged On August 20 at 12:50 a.m. the Collingswood Police Department patrol division noticed the fountain on Haddon Avenue overflowing with soap suds while on patrol in the area. The matter was turned over the detective bureau for further investigation. Investigation resulted in the identification of two individuals responsible for the criminal mischief to the fountain. One offender is an adult, who was charged with criminal mischief and released from custody pending a municipal court date. The other offender is a juvenile, who was mandated to complete community service as a result of his role in the incident. Residue from soaps clog the fountain and cause malfunction. Furthermore, foreign objects in the fountain cause damage, restricting the flow of the pump which results in motor burn out. It also encourages visitors to add items and play unsafely. “Adding objects or soaps to the fountain is a criminal act and violators will be prosecuted,” said Collingswood Police Chief Kevin Carey. - press release from the Borough of Collingswood
