best wifi security camera mac image
William
I need to hook up an outdoor security camera system but one that is also wireless. I would need to view it on my ipad as I am going away on vacation so something that doesnt need recharging would be the best

Hello
Here is a DVR that will work perfectly for you.

Most DVR's and cameras don't have the ability to view from your i-phone, and you cant just download generic software all DVR's and cameras uses different encryption , software, and compression so you cant use another companies software to view another manufactures DVR.
You want a DVR that has an app specifically designed to work with it like the one I am suggesting below.
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.
A good 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.
X4S Remote Accessibility
View all your cameras instantly and remotely, and configure the DVR through internet using eitherbusiness in real time from anywhere in the world. MAC or PC platforms (smart phones too). This allows you to manage your
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
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.

How to shut off certain devices from wifi?
Mohammad Z
I have to shut off the wifi to my sons' ipads so they can't go on the internet without my permission but I can't turn it off from the actual ipad as they are old enough to know how to turn back on. Is there any step by step way to shut their wifi on or off instead of changing password? By the way my internet provider is comcast.
Answer
You seek a technical solution to a social problem, which rarely works effectively or for very long. You'll find the never-ending quest for technical fixes to social problems in questions routinely posed here:
--How do I keep my { spouse | sibling | roommate } from { hogging the bandwidth with porn | using more than x% of wireless | staying up all night on Facebook }
You are about to become an iOS app developer. A quick search for 'ipad wifi restrictions', 'ipad and kids' and similar searches finds this is like the problem elementary schools and libraries face when allowing children to use computers, with no easy or cheap technical fixes. I believe the most effective fixes are a mix of technical and social fixes -- nice way of saying laying down the law with the kids, saying they'll be monitored, and allowing the kids to rat each other out as violators. Oddly, that's the same approach at large corporations I've worked for.
Apple iOS devices can be restricted (such as only connecting to a certain wireless network or disabling the camera) with locked profiles delivered several ways, including over-the-air, but it sounds more like an enterprise solution.
What you want doesn't appear to exist - a locked app that allows you to kill the WiFi remotely over the air, and probably requires you to connect the device via USB to re-enable wireless.
Lacking that, you can restrict the iPads wireless connectivity while at home:
--Purchase a wireless access point or router for use by the iPads. If it's a router, disable the DHCP server and connect it to your existing router using the LAN ports.
--Configure the iPads to securely connect to the new wireless router. Change the SSID and security key on your existing router so the iPads cannot connect to the old router.
--When the kids need internet access, turn on the new router. After their access is done, turn it off
When the kids start turning the router on without your permission, start disconnecting the new router at your existing router (assuming you put your existing router in a secure or monitored location). To make the disconnect/reconect easier, you may purchase another small 4-port switch to connect your old router to the new router - you turn the new switch on and off to disconnect and reconnect the new router.
If you want to be fair, establish a 'no internet' time for the family (such as 10 pm to 6 am) and put the main router on a timer. Your existing router may have some time-of-day settings that allow you to do this.
Your router may also have settings for time-of-day or service restrictions for individual devices by IP or MAC addresses, but do not expect that to work for long. This forum has many postings from kids trying to get around those router restrictions, which are fairly easy to defeat in most routers.
