How fast of an internet required?

Ah, those are cool, they are called PTZ or speed domes. Indoor ones are slightly cheaper. You an get an inexpensive one like from Dahua for only $599 but only 3x zoom, so depends on how you will use it. The better Dahua's PTZ that are 20x zoom run about $1,000 to $1,500. ACTi runs more, about $1,600 for indoor, about $2K for outdoors. Hikvision I believe is in between. Axis has their low end indoor PTZ, the 214 for about $1,200 and their outdoors ones tend to be about $2,500 and up. Panasonic makes an indoor one for about a grand.

 

What's your budget, knowing that $600 is the low end, and $4,000 is the high end. The good news is you won't spend $300/camera, LOL.

 

thats too expensive for me.. ill pass

If you want to cover a large area indoors, the ACTi E96 is available for $260, is a 5MP dome and is a fisheye covering 360 degrees. Their NVR software splits that into 4 90 degree streams so looks like you have 4 cameras, each pointed in a different direction. So it has the 360 degree coverage a PTZ provides without any movement and no zoom.

Also something often overlooked is what interface you are viewing it. If you are using a lower grade tablet or phone you may not even get the full HD so nothing to worry about!

Sure, but there's e-ptz. For example, I have a display with 9 cameras, clearly on my 1080P display, each camera takes 1/9th of that. But within each small window, I can zoom in to get more detail. The same on my tablet. When I view a 3MP camera, it shows me the full camera but I can pinch/zoom to leverage the full 3MP.

Not sure if anyone mentioned this, but Lorex and QSee are resellers, not manufacturers. They buy manufacturer brands with their own name on them, and each camera model may or may not come from a different manufacturer.

 

You're generally better off going with the OEM, or figuring out which OEM made the Lorex or QSee model you're looking at.

 

If you want to keep it below $300 per cam, you'll want to look at ACTi, Dahua, and Hikvision (there are probably a few others I'm missing). Under $200 leaves out ACTi. Do yourself a favor and avoid the budget cams like Foscam, Agasio, Wansview, etc, and the no-name Chinese ebay cams.

Different than a reseller, Lorex, Swann, Derytech/HK Series, Q-See are OEM's. What happens is they place a large order with the manufacturer with their specs, so similar looking cameras from one OEM may not be the same as OEM from another or the actual manufacturers version.

 

So why do this you may ask. In return for not having a lower price, the manufacturers sells them to OEM where they take full responsibility for support, warranty, inventory, marketing and sales. I feel with OEM there's a small risk in that they may not fully understand or even have access to the manufacturers firmware. So if there's a bug, it may take longer or maybe never get firmware upgrades. Also, one company like Swann may get products from multiple manufacturers.

 

Then beside OEM, you have domestic and imported versions of the camera. For example, you can buy Hikvision cameras and Hikvision USA cameras, different companies, different warranties, different price, same cameras. Careful when you compare prices, because you may see two vendors selling Hikvision and unless they specifically say Hikvision USA, it's likely the China Edition, not that it's bad, just need to know what you are getting. Typically, from what I've seen, Hikvision USA cameras cost about 25-35% more than Hikvision cameras. Dahua's own brand was not even officially available until very recently in the U.S., typically they only use OEM's and there are so many, can't begin to tell you all of them.

 

It is confusing, maybe it's the way in China, keep everyone confused, LOL.

and one more suggestion , use RG6 cable with HD camera's , dont use RG59 cable that is commonly applied to CCTV systems.

what is the reason of this?

 

HD camera contains more detail , hence has more bandwidth . Bandwidth capacity of RG6 is greater then RG59. i mean you can get more details on RG6 then on RG59 cable. another and most important reason is that after every 100m of cable run RG59 signal degradation is 8.7 db . and for RG6 it is 6.4 db. This means that RG6 can beter cop with outer noise.

 

3rd due to better copping capability with noise ; RG6 can be layed at larger distances upto 1500 meters in single run (1000 / 1200 m is recommended) , on the other hand RG59 can maximum run upto 700 m recommended.

There are many Bandwidth calculators available on internert . search for "HD camera bandwidth calculators" or Try this one .

 

http://www.stardot.com/bandwidth-and-storage-calculator

 

as For you need , 1 of this camera at 15 FPS will consume 4.1 Mbps. you need an internet connection of 4.1 Mbps or Above . normally it would be available as 6Mbps.

 

thx for replying.

 

But that camera says "30 fps real time recording" so why are you saying 15 fps? what does it mean by real time recording?

 

the internet of 4.1 Mbps that u mentioned is that download or upload?

 

I am planning to buy this internet package: http://img546.imageshack.us/img546/1950/7owh.jpg

As you can see download is 30 Mbps and upload is 5 Mbps

 

 

As Internet is intended to see camera's at a centeralized point , and both a camera and the CMS (centerallized management system) is connected to a Router that is supplying internet services. hence Uploads and Downloads are seen with respect to that Router.

 

HD Camera ---->> DVR ---->> Router ----->> CMS. (Download)

HD camera <<----- DVR <<---- Router <<----- CMS (Upload)

 

you need better download then upload . (PTZ cameras also require up load to send signals to PTZ cameras)

 

>> when you access resources from a server (say DVR) then you are downloading from Router.

>> When you request resources from DVR , (when you open browser or CMS to see video) then you are uploading to the router.

 

First : Real time means the rate at which camera is seeing the scene , we are also seeing at the same rate. that is 30 Frames per second (Fps). but at this rate we require more bandwidth. and if you are also recording at the same rate then require more HDD space.

 

Two terms are common.

 

1 - Record at low FPS say 15 fps or even less.

2 - see at real time 30 fps

 

Humen eye can not detect jitter (pausing of video) greater then 18 fps . and at 5 fps is some cases you can get all the details that are necessary for forensic investigations. there are standards to use destined FPS for different cases , e.g

 

for casinos 30 fps Record 30 fps View that means real time record and view (monitor)

for stadiums 1 fps

for schools 5 fps etc.

I used rg6 once to tie up my brother, and it did hold him better than rg59? These are network cameras, they use Ethernet cable like Cat5.

Ohh ... I am Sorry. Off course for Network Camera's we Go for Category 5 or 6 cables.

But could you beat him with better detail when you used the rg6?

 

And don't even get me started about the "skin effect" and the importance of using copper clad steel rg6 only for tying people up and not for CCTV...

your problem is you are quoting analog signal over coax and not digital signal.

 

HD-SDI is recommended to go over good RG59 not RG6 (rg6 will give problems)

 

signal degrades at 100m ........ no it goes off with digital with RG59 or RG6 its max of signal so extenders are needed at 95m to extend.

 

 

however a few companies are now selling HDCVI with a coax range of 500m for 1080p & 720p HD video format.
