Joe


I want to make a surveillance system so that I am able to have a camera or two at my house and one or two at my office (about 1 mile away). They need to be able to see at night and perform well outside as thats where the majority of them will be.

I would like to be able to have them all tie in together so that I can view them remotely from one place, or preferably my cellphone or a laptop.

Thank you in advance for any help!



Answer
Start with a budget. Is this worth $1,000, $5,000 or more to you?

Also, since you don't seem to have any specific data network or security camera experience, you might consider hiring this out or contacting a reputable security company to do the work for you.

Being a mile apart tells me you will need two different systems. One home, one office. The biggest reason is the two different local area networks (LAN) used that will connect to the internet.

There are essentially two ways to do this.

1) Analog cameras connect to a DVR, the DVR connects to the LAN.
In this scenario, there are two options. One has the DVR being accessed remotely so there are data network security and segmentation issues to deal with otherwise the video data could easily overwhelm a poorly designed network. The other has the video being sent to a "service" - most of the manufacturers have this - and to see what your cameras see, you log into their network.

2) IP network based cameras are on a LAN. The camera views are accessed remotely so there are data network security and segmentation issues to deal with otherwise the video data could easily overwhelm a poorly designed network. If video is to be stored, then add in a computer of appropriate horsepower and hard drive size to store the video.

In all cases, be sure to add a battery back up system that powers the cameras, DVR, router, hubs switches, computer and whatever else is associated with the security camera system. It would be silly to have a "power outage" cause a security camera outage.

Cameras rated for outdoors, with night vision (infrared emitters) will cost a little more than small indoor type cameras. At the consumer grade level for analog cameras (that connect to a DVR), plan to spend at least $150 per camera. Lorex and Swann make decent ones. If you need "vandal resistant" or decide to go with IP based cameras, expect to spend around $2,000 per camera. Pelco makes good ones. If Pan-Tilt-Zoom functionality is required, the camera price increases to around $3,000.

The DVRs at the consumer level start at about $400 for a decent 4-channel system. You may need to add a hard disc drive if the one included is not large enough. An 8 or 9-channel DVR weighs in at around $650. A good Pelco DVR will be in the $5,000 range.

There are several more permutations, but the gist of this explanation is that your simple question does not necessarily have a simple answer.

can you record from the video channel on your tv?

my security camera must be set up to be viewed from the video channel on the tv. so, while the tv is acting as a monitor as long as i am sitting there i can see whats going on in my yard, which is the purpose of the system. I need to record-not sit and watch the tv for 8 hours. I'm trying to see which neighbor is throwing trash in my yard. I have been told you can not record from the video channel. But this is the station the camera must be on. any ideas.


Answer
Just take whatever cable is going into the video input of your TV and run it through a VCR, then you can record it.

I would like to buy a security camera that I can plug into my computer and record everything without the need to purchase a dvr.
So my question is which is a good camera that comes with software to record everything in a computer.
Thank you!



Answer
I love looking at my security footage on the computer, too. I got my security camera at Spytown, and I couldn't be happier. I'm not going to suggest a specific camera, because I'm not sure what your home security needs are. But I'm sure you'll find one that hooks up perfectly with your computer!

I hope this helps!

What kind of security camera system should I buy to watch my house from a laptop?

I've heard-of a security camera system that I could watch my home from a laptop while at work. What company should I refer to get this setup, and will any laptop work?

Hello

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.

I suggest you buy a PC based DVR has they have more processing power and normally have a much smaller file size and offer more features then Standalone DVR's. I know many people buy a cheap standalone DVR, only to upgrade to a PC based in 6 months especially when they are using it to manage a store remotely. Also PC based allows you to record up to 64 cameras where a standalone will have a limit of 16.

Many people have the misconception that a PC-Based DVR is simply an off-the-shelf PC with video capture (encoder) cards, display (decoder) cards and some generic OEM software. A true DVR requires years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day. This makes consumer-level hardware inadequate for DVRs which is why Ascendent uses custom-built PCs with performance-level hardware.

My personal favorite DVR is Ascendent X4 series: Ascendentâs Tri-Fusion Hybrid Platform allows for the creation of a true hybrid surveillance system by utilizing the advantages of Analog, Megapixel, and IP technologies for unparalleled customization and expandability. I am working on government projects and use Ascendent cameras and DVR because the offer superior performance and cost less then comparable brands like bosh, Honeywell and pelco.

The X4 also uses the latest H.264/SVC codec offer video substantially better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.

File size is crucial to streaming because most DVRâs on the market record at real time performance (30FPS per channel) so on a 4CH is trying to send 120, 8CH 240, and a 16CH 480 images per second which requires way too much bandwidth even for the most extreme internet connections.

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. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent. These brands are what security professionals use, Q-see, Swan and Lorex are only used in residential applications because they are sold by Tiger Direct, Spytown, Newegg, Sams Club, Costco and other retail outlets but are not used by any security professionals also their tech support rarely speaks English as their first language...

These brand manufacturers also have a complete line of CCTV cameras for any application from residential to military.
