I need a camera of some sort to catch what my dad does to me when we disagree on something.. he gets so angry and sometimes hits me for being wrong etc.... I was thinking of putting some sort of camera on the ceiling or if it was small enough close somewhere anyway if there is such a camera where could I buy it?and write down personal expirecences thanks!
Answer
Please don't give advice when you have clearly never worked with CCTV equipment. Amazon sells complete junk and the video taken by non CCTV cameras often wont hold up in coart because they need water marking in the images.
What you want is a DVR a DVR converts analog cameras and as well as storing images on site allows you to distribute video over LAN and WAN networks. (internet and network) this way you have both on site storage and recording at your house.
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 cameras are based on CMOS
Analog cameras are based on CCD (usually)
A CMOS sensor is constructed using a array of pixels, but unlike CCDâs CMOS do not have a capacitor to store the charge for each pixel.The rows of pixels are activated sequentially rather then individually
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.
IP cameras have up to a 5X larger file size then analog cameras. (at same resolution) I have seen MP cameras that on 2MP resolution are over 300X (%3000) larger then our X3 DVR on a CIF image. This is an extreme case but generally speaking IP cameras have a much larger file size.
Most routers and switches are not designed to handle IP cameras they have enough bandwidth but they are not able to process the amounts of commands. (9 IP cameras 30FP is 230 instructions per second) standard routers have enough bandwidth (up to 1GB) but cant handle the amount of tasks (instructions) so frames get dropped latency is introduced and the effectiveness of other devices such as POS, printers and dats storage can be affected and compromised.
Donât get me wrong there are some brutal analog cameras and DVR out there but If you see a good D1 resolution image such as Ascendents Hardware compressed you will not be so quick to join the IP bandwagon.
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.
Make sure you get good cameras as well, Ascendent has the best IR outdoor cameras on the market and are about %50 less then Bosch while offering triple the distance.

Need help w/ outdoor security camera system.?
melissa
I need to buy an outdoor security camera system. Night vision and distance are a must. Need at least 4 cameras. Any recommendations? This will be my first security cam purchase so any info will be greatly appreciated! oh yeah, I'd prefer a reasonably priced system... Like maybe below $600 and still a good system. Thanks for the help 8-)
Answer
Hello
Peter that is the worst advise I have heard in a long time Costco, Walmart and online companies like Lorex (coscto sells lorex) sell very low quality cameras and often don't offer watermark so there images cant even hold up in court.
Giving advice when you don't know what your talking about is like giving direction to a place you don't now where it is, all you doing is wasting there time and in this case there money too.
The cameras from costco and walmart are used as nanny cameras that's all there good for.
Most IR cameras give you about 1/3 of the vision as advertised they call it "projected" distance now this had no coloration with what the camera will actually see at night.
A Varifocal (can change what the camera can see) lens with a good aperture 2 good examples are 5-50mm or 2.9~10mm. A fixed lens almost never works when installing a camera outdoors. Again to ensure you are getting a good lens and optics stick to name brands and avoid online retailers, eBay, Swann Lorex, Costco and Q see and other cheap no name products.
Also if you are buying good cameras get a decent DVR.
A good outdoor Camera will have
High resolution (520TVL or higher)
Good signal to noise ratio (S/N 49DB or 50DB)
A true Sony CCD (not Chinese knockoff)
Rugged enclosure to handle vandals and environments
At least IP 66 and a suitable temperature rating for you region
IR LED's to see in pitch dark: active IR rating not projected IR as projected IR has no coloration with how far the camera can see.
2 or 3 different sized LED;s 1 size LED one type of illumination means you either wont get distance or wide angle and you want both.
I would go with the VIS-56IR-2910
http://dealer.ascendentgroup.com//dvr-irâ¦
this camera will give you 110 feet of clear vision in complete darkness and great images by day its the on I recommend for budget customer who need outdoor IR camera.
Cameras that have high resolution, and great signal to noise ratio can reducing file size on DVR's up to 50% and offer better images.

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that's where the similarities end, itâs under the hood that counts.
Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means itâs not a good product and will probably have a working life of about 2 months. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 2% which means they canât afford to offer good service or allow for RMAs (returns). Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.
