Need help buying an IP security camera for home?




Rob Gane


I am looking at buying 2-3 IP outdoor cameras which will passively upload images to the internet. I am away from home a lot and I want something which will take pictures either when it detects movement, or takes pictures intermittently(preferably). I have a router for internet access which I want the cameras to connect wirelessly. Will I just need the cameras or is there something else I will need? And if you have any recommendations on cameras that would be great.

Thanks.



Answer
you can buy these cameras in China, there are many IP camera manufactures, you can buy 1.3 MP bullet IP cameras with IR lights, so you can see the video clearly at night, check this one:

Where is the best place to buy a security camera?

Last night someone turned on the water faucet that is behind the shrubs. So, someone had to be scoping out the house my parents or "Mother" called the cops because she believed it was something serious. They found a golf club! Im guessing this person was going to beat whoever came out to check it out but punk out or we waited too long to even know that the water was even on. I heard it but didn't think much about it and my sister thought it was raining lol.


Answer
Bunny Im assuming you have no experience in CCTV products. just because a camera says high resolution and long range does not make it either, no professional recommends q see products.

Few problems:
480TVL is not high resolution
36 LED's (q see are not very powerful) will give about 35ft
6mm Lens (fixed lens cant adjust view 42 degrees (not 80 feet day or night)

Here is a true high resolution outdoor IR Camera
VIS-56IR-2910 (Ascendent Technology Group)
High Resolution outdoor Long-Range IR Camera
550TVL Day (600TVL at night)
56 high output IR LED's (110ft illumination)
2.9-10mm IR corrected lens
IP 67 nema 4x Rugged outdoor housing

bunny there no point in giving advice when you don;t know what your talking about.


Hello you need a DVR and Camera

2 types of DVR's Standalone and PC based

Brand names who make good DVR's make good cameras.
I recommend Ascendent, Bosch, Pelco, Honeywell: Ascendent is best price and conformance but they are less well known.


I suggest you buy a PC based DVR has they have more processing power and normally have a much smaller file size and offer more features then Standalone DVR's. I know many people buy a cheap standalone DVR, only to upgrade to a PC based in 6 months especially when they are using it to manage a store remotely. Also PC based allows you to record up to 64 cameras where a standalone will have a limit of 16.

Many people have the misconception that a PC-Based DVR is simply an off-the-shelf PC with video capture (encoder) cards, display (decoder) cards and some generic OEM software. A true DVR requires years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day. This makes consumer-level hardware inadequate for DVRs which is why Ascendent uses custom-built PCs with performance-level hardware.

My personal favorite DVR is Ascendent X4 series: Ascendentâs Tri-Fusion Hybrid Platform allows for the creation of a true hybrid surveillance system by utilizing the advantages of Analog, Megapixel, and IP technologies for unparalleled customization and expandability. I am working on government projects and use Ascendent cameras and DVR because the offer superior performance and cost less then comparable brands like bosh, Honeywell and pelco.

The X4 also uses the latest H.264/SVC codec offer video substantially better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.

File size is crucial to streaming because most DVRâs on the market record at real time performance (30FPS per channel) so on a 4CH is trying to send 120, 8CH 240, and a 16CH 480 images per second which requires way too much bandwidth even for the most extreme internet connections.

The smaller the files size the more images 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 recording storage time, how much you can back up at once, how fast it renders and searches video. 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 important spec of any DVR.

If you are buying a DVR and streaming is a high priority I suggest you ask for a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVRs say they have remote viewing but it is often too slow and laggy to be of any use especially if it is a standalone. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent. These brands are what security professionals use, Q-see, Swan and Lorex are only used in residential applications because they are sold by Tiger Direct, Spytown, Newegg, Sams Club, Costco and other retail outlets but are not used by any security professionals also their tech support rarely speaks English as their first language...

These brand manufacturers also have a complete line of CCTV cameras for any application from residential to military.

I have done projects that required cameras to stream over satellite and cellular networks and the only DVR that could provide the video streaming was Ascendent Technology Groupâs X3 DVR. To give you an example of what a good DVR should stream like, below are instructions on how to connect to Ascendent's X3 DVR using Internet Explorer.

Instructions on how to connect to Ascendentâs DVR with Internet Explorer:

1) http://connect.ascendentgroup.com/ (Must be Internet explorer)
2) Install active X control
3) Hit âConnect)
4) DVR type PC
5) DVR code SITE-100
6) User ID Demo (case sensitive)
7) Password demo (lower case)
8) Hit extend config
9) IP address: 24.66.224.223
10) And hit connect

Again I recommend going with a PC based DVR but if you don't want to spend the money I suggest Ascendent's AVP-4120 DVR or Pelco's DX-4000 as they will allow you to view all your cameras instantly from anywhere in the world using either IE. The AVP-8240DVDUSB will also allow MAC platforms as well as PC to remotely view cameras and it uses the new H.264 codec but no standalone will offer the video streaming or performance a good PC based DVR will.
