"Power Over Ethernet" Security camera bundle?




ram156


I need to find a security camera bundle, containing cameras that are POE(power over ethernet) and can record to a remote server.

If the bundle contains a DVR system, its preferred it has extra channels for expansion.



Answer
DVR and POE are 2 different systems.

DVR uses analog cameras that are then recorded to a DVR. (Digital Video Recorder)

IP sends video over networks and records on a NVR. (Network Video Recorder)


POE is used to send power and video over a network cable but you are limited in range, routers and cameras.

Here is a DVR that will work perfectly for you.

This DVR converts analog cameras so that they can be transmitted over the network or internet as well as storing images stored 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 that location. You can even view and take snap shots with smart phones such and android and I-phone.

POE:
As for running power and video over the same cable use Baluns they allow you to send both video and power over a standard Cat 5 cable. Analog will give you better images, faster transmission and wont slow down your network so I highly recommend them over IP cameras.

You can even do up to 16ch: http://ascendentdvr.com/baluns/bal-a16r-32vo.html

Bundle systems are often cheaper but you rarely get the performance out of them.

You want every camera to be designed to give the field of view you need, each camera should be picked specifically for each camera location.

You cant just buy a 4 camera package and expect it to give you what you want.



Unfortunately many people buy very low end systems which have poor frame rate and bad image quality because they buy from Amazon, "spy stores" Lorex, Q-see, NCIX, new-egg, and other online retailers who sell cheap products for china there were never intended to be anything more then a nany cam and should never be used to provide security.

Not all DVRs are created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of DVRs you can find the equivalent of a $10,000 Kia and a $350,000 Ferrari and everything in between. Both have 4 wheels and windshield but that 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.



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.

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. 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.

DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.

Also as far as night vision or IR cameras go most do not give good images in the dark. Many companies claim good night vision but there are only a handful of brands who give night vision over 30 feet out doors. normally if a cameras is rated 150 feet of IR it will give you ok images at 30 feet at night and good images at about 20 if rated for 60 feet you might get 15 indoors and will be useless outdoors.

Some good CCTV brands that I recommend are Bosch, Pelco, Honeywell and Ascendent.

Economical DVR's
Two good economical DVRs I would recommend are Ascendent's AVP-4120 DVR or Pelco's DX-400. They will allow you to view all your cameras instantly from anywhere in the world using either IE, or a client software. The AVP-4120 uses the latest H.264 codec to improve streaming and recording time, and will allow PCs and smart phones to remotely view and control your cameras. These are the DVRs I would recommend that are good quality and affordable from companies who stand behind there products.

Again if you are going to buy no name products save money and get dummy cameras they are just as affective and you will be less disappointed.

Hope this Helps,

Looking for a Security Camera that Streams to the Internet for Live Monitoring and Capture. Anyone Make One?




Eric


Looking to add a bit of security to my home. So I am seeking a camera that streams video to the Internet for live monitoring and and will capture in the cloud. Does anyone make something like that?

Thanks in advance!
Eric



Answer
I had one from Lorex before, but it wasn't all 'recorded' in the cloud. I was able to view live footage from my iphone/android or laptop, but it would only record it when I set it to from my laptop (and it stored it on my laptop...using a lot of storage space). It did have a 'motion detection' feature though, it would take pictures and send the pictures to my email when motion was detected, or record to my laptop only when motion was detected. That came in handy.

If your looking for something that records all footage so that you can rwd/fwd/pause your going to be spending a pretty penny on a DVR/storage.

With mine, the camera required the minimal following:
A power source (I plugged mine into an extension cord coming from my porch)
A WiFi connection


It all depends on how much $ you would like to spend as to whether you can get what you want or not.
