What is the best home security camera?




Dragonfly


I am looking for a system of 3 cameras, that can record directly onto the internet. I would like to have something that is good in the dark and also has a good resolution.

Does anyone have any suggestions, because I have no idea where to start. Thanks so much!

Hello

CNB cameras are not high end and are made in china,

Spyville just sell products made in china and are also quite low quality.



Most IR cameras do not give good images in the dark specially cameras under $200. 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.

Economical DVR's
Two good economical DVRs I would recommend are Ascendent's AVP-4120 DVR or Pelco's DX-400. 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.

Always buy DVR and security equipment from a good brand name manufacturer like Pleco, Bosch, Honeywell and Ascendent: http://www.ascendentgroup.com

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.

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.

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.

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,

Why are CCTV / BNC security cameras such low resolution?




Anomoly


I'm sure that if your going military grade there might be much better but it seems that 'high resolution' security cameras for the most part are '480' which seems quite low compared to 1080 cameras out in the world today. (i.e. the WII vs PS3 resolution).

Am I just way of and ignorant here?



Answer
They are low res because:

-it is cheaper

-that is all that is needed in most cases

-low res can be recorded more time and take up less memory space

You can get a high res camera but it will take up a lot of memory in your hard disk recorder - security cameras record 24/7.
