Need Long Range IP Camera

[mediaeffects 0]

Can anyone recommend a long range IP Camera? Looking for a distance of around 200ft. This is for a fairgrounds. We want to monitor the lines at our gates. The mounting location is 200 ft away from the gate. There are so many places on the web to look.

 

Any recommendations?

There's not really such a thing as a "long range camera". Any camera will do, all you need is a lens with a long focal length. Depending on the area you need to cover and the size of the camera's sensor, you're probably looking at a minimum 50-70mm lens.

 

Keep in mind that with that kind of throw, even the smallest amount of shake in the camera will be magnified greatly in the view, so you'll want to make sure the camera mounting is VERY solid.

Thank you for responding. I should of mentioned lense and not camera, but you answered my question. Thank you.

IT is long range.

If you means can watch so long distance without lights at night. Fixed IR Cameras can not reach it. only Ir Speed dome cameras can do that .

If you can't find such products . suggest you get a speed dome and a Digital Video Server like this :

 

Here is a demo online of my IP cameras:

Camera like this can reach 80-100meters :

He wants to watch the crowds lined up at the gates of his fairground. Presumably, it's either daylight, or the area WILL be quite well-lit while people are attending.

We use the Avenir HZDG 12240P lens, its a 12~240mm lens we typically look at trucks 500 to 2000 meters away.

Axis 233D

It has 35x optical and 12x digital zoom but it is very expensive :/

You could use IR illuminator with camera. If you want to use IP camera i recommend you Spectra IP from Pelco or Autodome from Bosch or models from Extreme CCTV (currenlly Bosch) with powerful IR illuminator like Derwent or Forward Vision (Bosch as well). But initially IP camera has higher low-light sensitivity then analog camera. Also you could take ready complect "camera+IR" (there are few providers that supply such a equipment - Pelco, Videotec, Extreme CCTV etc) But if you need very high speed (one of colleagues in previous messages told about speed dome analog camera). You should use analog speed domes because there is delay in signal over IP transmition. For recording (in case with analog camera you) you can take any encoders (depend on your system).

 

Do not hesitate to contact with me for additional info!

We use the Avenir HZDG 12240P lens, its a 12~240mm lens we typically look at trucks 500 to 2000 meters away.

 

Thanks to zmxtech for the lens calc.

 

According to this at 200ft a 4ft wide view would need a 246mm lens. The Axis 233d has a 119mm lens. I haven't found any all in one cameras that have a lens anything like 200mm. The HZDG 12240P lenses is about $2000 AUD.

 

We just manage to fit one of these lenses into a Pelco Esprite but it is a tight fit. We make some physical mods to the lense and housing. And we are currently modifying an Esprite to support a megapixel IP camera. I will let you know how it goes. Mods to the Esprite include adding a Mil-Spec plug to the bottom to make them plug and play. Convert the power supply to make it solar friendly. Re-route the serial cables so the serial data comes from the camera. And replace the serial interface from the input to support IP to the camera including PoE.

 

Here are some photo's unfortunately I couldn't find anything at 200m worth focusing on apart from piles of dirt so these photos are at least 500m away. Camera res is only 800x600, very dusty environment so all the trucks and equipment are covered in dust and are as dull as the photo's look. It is also very hot and deep so there are laminates of different air temperatures that bend the light coming to the cameras.

 

So here are a bunch of near and far shots with a 240mm lens

 

In the first two photo's the truck is 616m away, I have live feedback of GPS of all the equipment so I can accurately calculate the distance to the meter

 

 

In these 3 photos the shove is 1364m away and 285m deep.

 

 

 

The drills are 858m at 285m deep.

 

 

 

 

The last shovel is only 510m away and 285m deep. The closeup is a bit blured as the capture snapped between two frames.

What cameras?

[woodyads 0]

Ikegami ICD-808P they are 4 years old. These use the HZCG 12240 lens. We pipe them into 7501EXT DVTel encoders at the source.

 

We are moving to the DVTel DVT9580A camera. It uses the HZDC12240 direct drive version of the lense. It should be a lot better as its direct digital to IP. Removes the need for an encoder and is 1280 x 1024. We have bench tested the camera and lense, done a proof of concept on converting the Esprite to IP but are yet to field test the final package.

 

I did ask my distributer to look for a better lense but he couldn't come back with anything that would fit in a housing. Since then I have come up with some bigger housings to fit the Esprite but the modification is pretty heavy. At the end of the day my image quality will always be hamstrung by distance. The further away the more atmospheric disturbance and the more dust. So moving the cameras closer to the action is the solution I have now solved with mobile comms trailers

Why did u pick DVtel

12 frames at full resolution ?

just curios

Thanks

I don't care too much about frames, I am not watching a movie. Most of the time when we play things back its at fast motion anyway. We use it for replaying safety incidences. Understandable that you would care if you were in a casio and you where watching for slight of hand.

 

What we want is to be able to see the number on the truck. We currently run with a throttle of 1000KB/s which is about 5 frames per second. This give us 12 days of recording and keeps bandwith low.

 

DVTel had a very good NVR security model that let me share out to many uses in different groups and group my cameras and control PTZ access to different groups. Its security model now isn't that crash hot, but since the system I put in 4 years ago has done well I will stick to it until I change the whole setup.

Hey AK357 did you have a camera in mind that would do the job better? Its got to support Multicast, be the right size, take a c/cs lense or a 240mm lense, efficient codec, fit in a PTZ or have a well supported PTZ protocol. I would have liked to have found a higher Pixel camera.

how do you keep the dust off the lenes ? air- water etc?

[woodyads 0]

Its a not too much of a problem. Every now and then you can face them up during a storm but we go 6 months without rain. So you just wear the dirt and clean them once ot twice a year. Now we tend to mount them on the hand rails of trailers with working platforms or on ground based frames so they are easy to service.

 

We are yet to stick one on the telescopic masts and they were bought with that in mind as an option. We have three 15m air powered telescopic masts that can handle a head weight of 45kg. However we worked out that it is important to hold the camera as still as possible when looking long distances. Masts cost about $17k each.

 

I guess the vehicles we are looking at are dirty in the first place so it hides it pretty well. All the stills were taken from the same camera and only on one is it obvious the PTZ cover has lots of dirt on it. Still it would be nice to clean them a bit more often

Hello

I recommend Axis 233D Network Dome Camera because Axis 233D is designed for use in challenging surveillance applications - such as airports, stadiums, casinos and ports - where the ability to follow moving objects from a long distance and see great detail is crucial.

 

Thanks
