For Correct operation you would do a survey [like wispy] and then put the cams on non overlapping channels away from the noise -just like any other wifi setup

 

I do many of these WIFI setups to 60 at a time -4 per floor etc.

 

Looking at your setup you would see the signal strength is down and the carrier to noise is high which would suggest a problem.

Putting diverse semi high gain antennas on your AP will improve things also [which will crank the BW /fps up]

What's weird is my test case has the cameras within about 15 feet of the AP. If there was interference causing it, then all the cameras would choke.

But what happens is one of the 3 cameras will just stop working and won't respond. Once I power cycle the camera, it works fine for day(s).

And let's say there was intermittent inteference, the camera should still attempt to keep responding, and not lockup, right ?

When the cameras are up, the frame rates are high and the RF environment is pretty clean (I do have WiSpy 2.x).

I've tried all kinds of routers, AP's and antennas, this problem just won't go away !! ARGH!

I am trying to get Axis to help me solve this lockup problem with the 207w.

With my test case the cameras tend to lock up after about a day or two.

Difficult to pinpoint why or what causes the lockup. The camera just stops responding all of a sudden. The camera wont respond until you reboot it.

I have the latest firmware in, so it's not that.

Hopefully Axis will be responsive with this issue, it's been over a year now.

so even though I found a major source of interference and got rid of it, the 207w's still go off to sleep sometimes and don't recover until you power cycle them.

It has been a very frustrating situation, I've been round and round with Axis, and no solution.

I would suggest highly that you don't put one of these cameras in for a real situation, they aren't reliable.

good info ! obviously frame rate & bandwidth needs to be taken into account as well.

Hi, try BiKal EyeSoft, with no per camera licensing with 4, 8, 16, 32 & up to 64ch

 

Bikal Eyesoft looks identical to Novosun Cyeweb when looking at the screenshots.

Wich is the original?

from looking at the two websites, Bikal looks to be a "solutions" provider, and NovoSun Cyeweb must be the original application, rebranded for Bikal. Just my thought...

Used it once .. Extreme CCTV Camera ... not cheap and wasnt an IP camera. Used at a gated community entrance, pitch dark at night. worked perfectly.

is there anything that works good for LPR that doesn't break the bank ?

My silly attempt at LPR made me realize that the camera has to deal with:

1. varying light intensities (outdoors)

2. glare off the license plate (also plastic plate covers)

3. off angle camera view

4. varying speeds of cars

5. IR at night and daylight require different approaches

my situation involved trying to get LP's on a private road, where cars can be travelling from 5-20+ mph. Where 20 mph is way too fast, but people probably do it.

the camera is mounted looking at the street from an angle (about 30-40 deg), and the FOV is about 60 deg.

We basically gave up on pursuing this part, but I still would like to know what would work well. maybe nothing ?

did you have any noticable difference in the daytime pic when you changed the 207mw lense? I did this with another lense and ended up with a IR daytime pic..........

 

what "kit" did you purchase? there are multiple...................and can you post a pic?

the picture looked good to me day or night, this is the product I purchased:

note: they were bought out by LogiTech !

can anyone put up review / images from ACTi ACM-5601 ?

hi

i want to recomend the new messoa 265i....

works great at any condition or speed

i installed it in a factory entrence - and the result are fxxx great !!!

nice looking camera, but this isn't an IP cam...

pls advise us about IR lens you used..where you got it/manufacturer..

The kit for the IR was $60 which includes the IR lamp and wide angle IR lens. it's from Lukwerks (wilife).

Visec has a LPR module.

Has anyone tried that ?

not sure what you consider "inexpensive" but the cheapest thing that I found to work is Active WebCam. There are other cheapie programs but I haven't tried them, such as BlueIris (never tried).

Active Webcam is a bit buggy but for a cheapie piece of s/w it works ok. Support is not very good, but they do come out with new versions. It actually has better features than many of the other programs I tried that were more costly.

I have it working with Axis 207, 221, and Panasonic CL-30 no problem.

Overall it works pretty good, I have had a few issues with it, but for the money there isn't anything I know that works better.

The motion detection works pretty good, but the frame rates seems to max out at about 8FPS and I can't get it faster. So for this reason, I am actually moving to Visec.

Visec isn't as cheap but still low cost, and it works a lot more efficiently, I get almost 20+FPS on a regular PC w/XP.

there is a section in the 207MW's wireless network setup that allows you to type in the SSID of the "adapter" you want it to link up to........

VST_Man...sure, but what do you mean here ?

 

Well the software running as a server is hyper efficient. I am recording 24 cameras at 30 fps D1 resolution MJPEG right now on a Celeron 1.8 GHz processor (a little test box I made). CPU is about 13-24%.

 

Watching the cameras though takes more CPU. What frame rates, resolutions and formats you looking at doing?

well my test case customer has 5 IP cams. All are D1 MJPEG res, and desired frame rates would be 10, with motion detection.

I have another customer with LuxRiot, has 6 IP cams, D1 MJPEG, at only 2-3 FPS. It pretty much bogs the server, but to be fair the server is nothing great. No motion detection.

I find that motion detection is usually the bottleneck....

now that I know it was interference causing the failure in the wireless system, I guess the reason for the original problem in this post is that the 207w's just never had enough free bandwidth to send data. they were essentially were "drowned" out by the beacon blasts of hell from the analog wireless cam.

since the analog door cam was not always transmitting (motion detector), rebooting the 207w's would get the system going again. until the next blasts occurred.

I'm still not exactly sure why the 207w's would stop responding after awhile, but maybe they give up after awhile if they can't "talk" back to the AP. That doesn't quite make sense to me...something to still look into.

wi-spy was awesome. I purchased the 2.4x model, which is a bit more $ than the basic one.

easy to understand the graphs, and it seemed to work really well.

pretty low noise floor, at -110dBm

attaching 2 of the jpg's from the testing.

you can see where the door camera was turned on and off

can anyone comment on how efficient exacqVision is ?

will it run on an average PC without bogging it down too much ?

I know that depends on what cameras, frame rates, frame sizes, how many cameras...etc.

for example I have been running Visec with 5 ip cameras, Axis 221, Axis 207w, on a basic PC (good cpu, XP, and plenty RAM) and it seems to work pretty well.

just to follow up on this thread...

I bought a Wi-Spy RF analyzer and was able to track down the main interference problem to a simple analog wireless camera that was being used at the main door about 150 feet away.

I never thought a simple little camera would generate so much RF. The analog camera signal was atleast 20db higher than the 802.11G channel (-70dbm), and I was sitting right next to the DLink wireless router.

simple solution, unplug the wireless analog camera, and wire it in.

now the 802.11G setup is working well, with the 207W cameras operating as expected.

if anyone is interested I can post the wireless test results (jpg's) from the Wi-Spy

Thanks guys thats great help, like the option of using the cheaper analog cameras and the dvr but taught the IP cams would cut that all out, thus cutting costs. but I do get your point about using the bullets.

 

ok so I've had a look at the farm and the house is as the farmer said 300meters away. The house has got just one pc and the BB connection is going directly into her pc. hence no wireless router.

 

Ok i now need two wireless router's one each end and two larger external antennas? any recommendations?

 

Also whats an approx cost of the Avermedia 1304?

Sorry for the stupid questions guys

I like VST_man's suggestion with the 1304 Avermedia & std CCTV cams.

The 1304 is only around $400 (no HDD) and the cams are cheaply replaced if damaged. Note the 1304 is only a 4 port system, if you need more cameras, you will need more 1304's ganged together.

Obviously you need a spot where the 1304 and cameras can get power. The 1304 will need to be in a sheltered spot.

The 1304 will plug into a wireless bridge, which has a good directional antenna. Spend your money on a good wireless setup, because 300m is a long distance to make the wireless work well. hopefully it is a clear LOS (no obstacles).

You can later plug in IP cams if the 1304 setup is not enough resolution for you. All you will need is a switch that plugs into the wireless bridge.

On the other end, you have a wireless router and a good quality directional antenna.

Most likely you will need a Yagi's or high gain directionals to get a good signal between the wireless bridge and router.

The router is the only thing you need the DDNS to work. The modern routers have that. Granted this is only needed if off site internet viewing is required.

to answer your IR question, usually it is just the lens that is the blocking factor...make sure you can put in a IR lens and it should work.

Infrared Lenses are designed for use with Day/Night cameras. They eliminate focus shift in night mode, especially in the presence of IR lighting.

as for my comments on wireless, if you go this way do not skimp on equipment. wireless can suck in huge ways. do a site survey first...most likely in your case it is clear and a good candidate...but it will never be as good as direct wire.

When talking about video surveillance software, it comes to my mind the compatibility with the chipset, is there a single or just a few major chipset makers from which major ip camera makers liked Axis, Vivotek, etc. actually rely on?

 

 

Tks, Dove

 

for the open IP s/w, it's all capturing MJPEG streams. some prgrams allow control of the IP camera functions.

 

I don't think the camera chipsets come into play however..wrt the recording sw.

 

 

That confusing me. For example, I find Axis offering MJPEG and MPEG-4 picture, Vivotek offers MPEG-4, etc ... for recording purpose and monitoring only, it seems reasonable to capture only the video stream based on certain industrial format. However, the controlling, e.g. set the frame rate, set password, etc... I do believe they're more platform dependent. Moreover, a software with only viewing function without controlling function seems in-completed.

 

The consideration for me is that while there are software compatible with so many ip cameras from multiple makers, are they actually using similar structure, e.g. chipset? Just it.

 

Just my personal point of view.

I don't know of any open ip s/w that can record using MPEG-4 they all are using MJPEG, as far as I know.

IP Cameras using WEP ??? Most true ip cameras dont have built in Wireless functions. The access points would be using WEP or WAP or some other form of encryption format. Ip cameras being ethernet wont have care what you use as long as the link is good and stable, meaning you might want to change channels on your AP and wireless router and see if that helps. There is just a lot of 802.11 2.4 ghz stuff out there conflicting with each other. Using WImax or a mess will greatly improve your usage, or moving to a 4.9 mhz type.

 

As for 12vdc up the coax with video too, I havent seen a product to do that. I believe that the lower voltage would interfere with the hz sweep for the 1.0 volt PP analog video signal.

 

Hope this helps.

yes wireless IP cameras have WEP...Axis 207W, 207MW for example.

For lower cost systems, the self contained wireless IP cameras would desired.

who has used Visec or ViewCommander ?

any feedback on those ?

I tried both evals, I kinda like Visec...

What IP cameras and wireless equipment were you using?

Also, I was not talking about IP cameras with built in wireless.

I have only played with 802.11G for IP cameras. I haven't gotten too serious with wireless, because of initial problems. I know there are other proprietary wireless systems out there. Everything I bought is plain old stuff for 802.11G networking.

While it seems simple to setup and make it work, if there is a signal problem, it can be very difficult to solve. Also you cannot be guaranteed that a signal problem won't pop up in the future, intermittent or permanent. many things emit in the 2.4 GHz band (microwave ovens, wireless security systems, cordless phones, bluetooth devices), people put in wireless routers like they're eating candy. and construction changes/obstacles may cause a signal drop.

The only self contained wireless camera that I have used that worked decent was the Axis 207w..your fav! I used it primarily because it a). works, and b). has a good image for the money.

I also have experimented with a wireless bridge, using a regular wired IP camera which worked but due to signal problems I went back to direct wire. I would say this is a very good way to go, if you have the budget and room for wireless bridge, camera, power, battery backup etc...if the camera install is outdoors, it can be hard to implement this way. otherwise you need the self contained wireless IP cam. also getting uninterruptable power to it is something to deal with...(no POE with wireless!)

I'd love to know a better wireless camera. I haven't tried Vivotek's stuff yet. Can you recommend one ?

When I was looking at wireless cameras, it seemed that most manufacturers were creating a low end product, and were really more toys than anything else. Now it seems there are more products coming out that could be better.

Meanwhile I still struggle with poor throughput problems on a wireless install.
