Cameras Vertical Streaks in bright sunlight

[mattdb 0]

I am having trouble with some "cheap" outdoor camers that only seem to have problems in bright sunlight.

That is what it looks like.

 

Here is the camera that I am using:

Your answered you question. "Cheap" cameras. It looks like the camera does not have an actual iris. It is probably getting too much light. The electronic shutter does not reduce the amount of light but the amount of signal.

-Cmos

-380 TVL

 

You will get these results with those specs.

Those are not the correct answers.

 

I want a different "cheaper" answer

 

OK, seriously, now what do I need, that wont break the bank?

Mattdb,

 

If you can't find the answer to your question....then change the question (anonymous)

 

This is a CMOS imaging device not like the CCD imagers we see in most cameras. Although there are advantages/disadvantages of these cameras uniformity (image quality) is far superior in CCD. Although the CMOS does offer a compact package and low power consumption, it will have a lower image quality therefore not intended for low light applications. Looks like there is no IR cut filter which is why you are seeing the white strip (you may also see "motorboating"as well).

 

Don't know your application, budget or area you live in, but look for something that is 1/3" hi-res CCD (Sony) with 480 TVL. Lense and IR will depend on your application.

 

Check out "Camera Suggestions by Manufacturer" in the forum. As well, please visit our advertisers as they may be of service. Vitek and SpecoTechnologies are two companies which may have cameras to fit your application.

What is the overal difference between a 1/4" 480 and a 1/3" 480?

[rory 0]

There are many types, versions and models of chips.

 

Need to know if they are both CCD, or one is CMOS and the other CCD ..

 

Are they Sony, Sharp, Panasonic, etc?

 

Do they both cost the same? .. (there are many versions of the same type of chip also from a budget Exview, to a Professional one)

 

If they both cost the same price range, both from the same manufacturer, both have the same exact features, then the main difference is one accepts a 1/4 inch lens, the other a 1/3" lens, the larger the CCD normally the more sensitive it is also .. and when you look at the difference in lenses, simply a 1/3" 4mm is wider than a 1/4" 4mm ...

 

As for the 480TVL, resolution is dependent on the camera itself .. they all differ, but Picture Elements or Effectice Pixels are more important than going by the specified TVL.. . which BTW is incorrect most of the time, especially with OEM cameras.

I would really like a wide angle of view.[/img]

[mattdb 0]

Or even better does anyone have a good recommendation for one that is around 100-125 that is outdoor, wide angle, night led's 30-40'+?

[rory 0]

The first one is probably best quality, as I know who makes it. But its a narrow lens.

 

The Second one is 1/4" 4.3mm lens so thats about the same as the above for lens view.

 

The 3rd is 4mm 1/3" so its wider than those above, but not really wide angle 1.9=fish eye, 2.5-3.6=wide angle, 4mm=normal), also no IR and low Res, though all those bullets will probably be around the same amount of pixel elements anyway.

 

For that price you wont get a Day Night camera, just a Color IR .. but that should be fine for just inside a small room.

 

Are you buying retail or dealer?

CP cam have "cheap stuff"

 

108 AUS for ir cam to 15m 480tvl 1/3" coke can style would suit you perfectly, and cheaper in US.....

[mattdb 0]

Buying retail.

 

This is harder than I tought it was going to be.

 

Ok:

 

I want 480 Lines, 30-40 feet IR Night, outdoor, 1/3" ccd 3-4mm.

 

Now what is one that is around 125?

[rory 0]

Just saw you said outdoors .. thats where the issue raises, for the 30-40' IR bullets that do outdoors (anything can light up inside a room) they will cost double that ..

OK to hash this out some more, how does this look?

 

* 1/3" SONY CCD Image Sensor Day & Night

* 480 TV Lines High Resolution - 600 TV Lines in B/W

* 0 Lux with 48 IR LEDs on

* Weatherproof IP66

* Black Housing built in aluminum

* Range up to 90 feet

* Automatic IR triggers On under low illumination / Off under Normal Illumination

* Sun Shroud to reduce glare and dissipate heat

* Lens 3.6mm

* Up to 90 feet range

* 12V DC 1000mA (Regulated power supply is highly recommended)

* BNC/DC Jack

 

 

120 bucks with out power supply.

Initially CMOS chipset can preview "ok" image. but days go long, the problem start come like color turn yellow and image signal drop.

 

Never ever go fot CMOS even though it is cheap. It is not reliable.

 

for wide angle IR camera, just get a 1/3 sony and with 3.6mm standard lens. it fit your needs.
