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.

You should not pay any monthly fee for your CCTV system just store your images on site.

95% of cameras and DVR will not allow you to view them with the I phone or other smart phones.
And even then you need permission and password.
