anybody has experience with ip cameras?




Curious Du


So i'm looking to wire up my house for surveillance, I dont need anything too fancy like $200 cameras or so.. I'm looking for something that will just work, I would like it to have pan and tilt, and maybe zoom would be nice.

I have heard about the brand Foscam, do anybody have experience with this? reviews?

And, if not, can anybody recommend a trusted brand ? nothing too expensive, but something that is not cheap either, I will need it to work. I want motion detection and etc.



Answer
Not familiar with the hardware end of things, but if you want pan, zoom & tilt, you're probably going to pay a lot more.
A Wide Angle, with hi-resolution may be cheaper, and still cover a decent area. Check on the "Resolution" for field of view (may be in degrees) to get a comparative idea. Get 2 cams if necessary for full coverage. (some of the items below can handle multiple cams).
For software, here's some free items that work pretty good:

Pick one you think fits the bill, and hook it up inside the house to try it.
Get another one if it's too hard or doesn't cut the mustard.
Good luck.

Need recording software for an RCA surveillance cam.?

I recently bought a night vision RCA surveillance camera as well as an RCA to USB converter to plug it into my computer. I now need to find a program paid or free, to view, and record with this camera using a separate condenser microphone as audio input. Recommendations?

Answer
These brand manufacturers also have a complete line of CCTV cameras and DVR for any application from residential to military and stand behind there warranties. You want to get a good bran name otherwise you will likely buy a product that work and cant be returned.

95% of all IR cameras on the CCTV market are not IR cameras they are cameras with IR LED's on them,

A true IR cameras was desinged to be an IR camera which means the CCD, Lens, IR LEDS all work together for proper exposure.

The camera you are using is putting our to much light so it is overexposing the image becasue it is not properly designed I am willing to bet you bought your CCTV system from: Q-see, X10, Swan, Lorex, and other low grade DVRâs and cameras sold by Tiger Direct, Newegg, radio shack

If you bought a really cheap IR camera from a non brand name you most likely wasted your money,
Cheap IR cameras are standard cameras with $4 IR LED's on them, these cameras were not desinged to works with IR and they don't. A good IR camera are very complex and use special filters, optics, CCD, EPC and PCB that sync the camera with IR illumination for accurate illumination that eliminates over and under exposure and over exposure for perfect images 24/7.

There are only about 3 companies I trust for IR cameras.

Extreme CCTV, (Bosch) Peclo and Ascendent Technology Group.

The Best is Ascendent but they are harder to find as there a smaller company but they do offer better products and are actually cheaper. They supply IR cameras for military, and boarder security an offer thermal up to 40km and Active IR up to 8km. So there 500ft and bellow is amazing.

Don't buy IP cameras:

Just about any Analog DVR will do what you are looking for and not only display them but record them as well they will also allow you to view them over the internet from a Iphone or laptop.

Many people have a misconception that IP has Superior scalability then Analog but with the advancements with DVR's this simply isn't true, you cn do up to 16,000 cameras each camera could even be from a different DVR and a different site.

And when you are using the internet to connect multiple sites together analog transmits over the internet faster with less latency using less bandwidth allowing you not only to view and monitor a situation real time but also effective control PTZ cameras.

What is the Advantage of IP?
Many of the so called advantages of IP simply don't hold water in the real world, IP is mainly Hype and marketing and outside of a few niche applications such as 1 or 2 camera installs, where MP cameras are needed or large scale wireless projects which represent about 2% of the total CCTV market, IP has very few advantages compared to analog based on performance, cost and reliability. (yet all companies touting IP will often use MP cameras to demonstrate the advantages of IP)IP video is more about marketing then it is about performance as larger companies like Bosch pelco Honeywell axis can change for both hardware and software and once you use there cameras you have to keep using there cameras unlike analog.
Also IP sounds great, plug and play, Better image quality, use existing infrastructure, who wouldnât want that unfortunately this is often not the case.

IP is like wireless (in theory its perfect) if that was true there would be no wired cameras or analog cameras it would all be wireless IP.
This means CMOS has some significant disadvantages compared to CCD, this means CMOS
have inferior ability to cope with ambient lighting such as back light, bright, deep shadows contrasts, low light and IR this is also known as the real word.

In short unless you have perfect lighting a good CCD camera will outperform an equivalent CMOS camera.File Size:
The smaller the files size the more images that are able to be sent and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities as it also determines the recoding storage time, how much you can back up at once, how fast it renders and searches video. (Ascendents X3 DVR achieves file sizes as low as .3KB on normal image quality on a CIF image no IP camera on the market will come close to this) The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most import spec of any DVR.IP is a young and emerging technology and I have no doubt that in the future it will outperform analog cameras but its not a mature technology yet. Once we start to get standard IP platforms, get rid of license feesâ and existing networks have larger bandwidths then IP video will be a good solution, but until then analog is the way to go.


Hope this Helps
