Home security camera?




Jason S


I want to buy 1 camera, to place in a window that can view outside my house at night. I'd like to set it and forget it. I need it to record all of the time, and be able to access it when something is vandalized. I'm thinking some kind of DVR. Can anyone who currently uses a system like this let me know what they use, and if they like it. I've already looked at a number of internet sites, but they don't have product reviews.


Answer
My employers had this done right after the new year. I know its real. It has a red light that comes on when you get about 50 feet away. The local camera shop (Creve Coure Camera) installed it. I hope this helps. If no camera or security shop is nearby try this link; http://www.scdlink.com/results.cfm?category=13&secondary=26

Outdoor security camera system?




Casey


We have recently installed a chain link fence behind our home and are planning on letting our great pyreneese out during the day when we are at work so she is not kept in her kennel. We have an awning for shade and shelter, and we will be home around 4:30 or 5:00 each day to check on her. With that being said, we have had issues somewhat in our neighborhood, due to a busy road behind our house. I am not comfortable leaving my dog outside all day or at any time actually without some sort of security system to monitor and video my dog, in case someone was to stop or try to pester etc my dog. I have looked online and have found a ton of outdoor security cameras, however, I have no idea what I am even looking for. I want something that records so that if I come home and somethings amiss, I can check the recording to see what happened that day. I also am needing this to be wireless and obviously weatherproof. All information, models, reviews etc are greatly appreciated.
Rick B......If I find something amiss, the camera will help me to identify the vehicle that had stopped....I never once said my backyard was unsafe...I said we have had issues in the past (such as speeding cars....stolen lawn items) believe me I would not let my dog play outside if the area was a danger zone and I thought she would be harmed or killed, however, as a responsible adult, I would like to have eyes on the area when I cannot be around. I am very proud of you for taking such good care of your pet. I too live in a nice community outside of town, with a covered patio and a wooden fence surrounding my patio, both with gates and a doggy door for my 80 lb dog to retreat too if needed. I also have a locking gate on our chain link fence surrounding the rest of our yard. Once again, I never said that my area was a danger zone, but yes, I live in reality where every great once in a while there is a bratty kid that comes by speeding, or steals my neighbors lawn ornaments. I have d



Answer
Two types of systems:

1) Analog cameras connect to a DVR. The DVR connects to the computer network at your house. The DVR has the feature/functionality for the cameras (i.e., motion detection, send you email when an alarm event is triggered, local video storage for later review, etc.).

2) IP-network based cameras connect to the computer network at the house. The camera becomes a network node. For local video storage, a Network Video Recorder (NVR) is used.

Both methods have pros and cons. What I have found:

1) "Wireless camera" is an inaccurate description. The camera needs power (wire 1). For the first option, the wireless video signal is sent to a base station (or receiver). The receiver plugs into the DVR (video signal) and power (wires 2 and 3). Usually, these cameras are transmitting in the 2.4 Ghz range. This is a shared spectrum and can have interference from lots of sources - including wifi, garage door openers and cordless phones.

2) IP network cameras seem to be more expensive than the analog cameras. The imaging chip seems to be the first thing to go on any security camera, so I use the analog cams (connected to a DVR). The decent consumer cams start at about $150 or so. Less than this and I find myself replacing them at least annually - but at this price point (or higher), they seem to last a bit longer.

3) Because the DVR is on the network and maintains the features for the cameras - including network connectivity for remote viewing and storage, the cameras can be "dumb" = less expensive.

4) Set a budget. I like/use Swann and Lorex gear. It is more expensive than some others, but I have learned (the hard way) that you get what you pay for.

5) We don't know the yard layout. Generally, I would install cameras under the eaves of the house so they have some protection from the elements. We don't know where you are, but extreme heat and cold are not good for electronics. Installing under the eaves helps protect them from the elements (even though they are outdoor rated). If there are environmental extremes in your area, plan to replace the cameras often - or install them in protective housings. This also makes access to power a little easier if you go the wireless route. If you go with wired cameras, then running the single cable between a camera and the DVR may also be easier. That single cable has a couple of plugs on each side - one for power one for video.

You can have a mix of wired and wireless cameras.

6) Set a budget. For just the cameras and DVR, plan on about $1,000. If you can do the installation, great - otherwise, plan on that expense. Again, we don't know the layout... I suggest starting with a 8 or 9-camera DVR, but with 4 cameras. Example:
http://www.amazon.com/DVR8-3200-Channel-Digital-Recorder-SWDVK-832004S-US/dp/B00GBYMUNO
The DVR has a large internet hard drive, 4 cameras get you started and when you want to add more, you have capacity. You do not need to use Swann cameras... but these
http://www.amazon.com/Swann-SWPRO-760CAM-US-Pro-760-Wide-Angle-Camera/dp/B008B4K7O6
I like a lot.

If you choose to use only 4 cameras for your stated purpose, no big deal - add cameras to the front and side of the house if you want... or leave the channels unused.

7) You can provision the DVR to send you email when there is an "alarm". If you set up the motion detection areas, that can be an "alarm". Be careful with this - you can end up spamming yourself with unnecessary email alarm alerts.

8) If you are familiar with how routers work, you can set up remote access through your home's router and get into the DVR remotely (after you get an email alert) using a smartphone with an installed client or a computer (Windows or Macintosh).

9) POWER:
if you are concerned about power outages and losing video then some sort of power back-up will be needed. This is where the wired cameras are easier - with the power and video signal coming to a single place, the DVR and all cameras can be plugged into a "UPS" commonly used for computers. And if the DVR is located near the computer network router, that can be plugged into the UPS, too. If "wireless" cameras are used, then each camera will need its own battery backup power supply.

How is the Mac notebook better or worse than pc notebooks?




BabyJ


I am a college student and does a lot of work like writing papers, graphic arts, research, etc..From your experiences which system runs better.

what are the technical differences?
Which is a better investment?
what do you suggest is a good notebook to get.

Preference
Size: 13"-14.1"
Price: up to $2000



Answer
From my experiences, Macs are always superior to Windows machines. It's not so much about hardware as it is about software. Mac notebooks use essentially the same hardware as PC notebooks, but Macs are better engineered. Apple engineers their own logic boards (or motherboards) and carefully plans how it's components will fit together, making the thinest, lightest notebooks possible. Mac OS X, being a more advanced operating system than Windows, will give you long battery life, ease of use, stability and unrivaled security. Despite what the PC cheerleaders tell you, there's tons of great software available for the Mac. I do a lot of different things on my Mac, from recording music to editing video and photos. I haven't found one single task that a Mac can't do better than a PC. Macs aren't plagued with the malware found in the Windows world. Why? It's not lack of users or low market share. The sole reason Macs are more secure is the fact that Mac OS X is based on solid Unix. Yes, Macs can be a little more expensive initially, although not by much, but you'll be saving money in the long run. You won't need to upgrade your hardware just to run the next version of Mac OS X. Macs have a much longer life span than PCs. A seven year old iMac can still run the latest version of Mac OS X. You won't have to waste any money on anti-virus software, as well as any system resources. The Mac would be the wisest investment. I know it's been mine. Macs work well because Apple designs both the hardware and software. It's this closed system that allows the Mac to "just work." You'll never get this kind of hardware and software integration in a PC.

If you have a $2,000 budget, I highly recommend the $1,999 MacBook Pro. I have a 15" MacBook Pro myself and I love it. It's light, thin, has a bright display, built-in iSight camera, backlit keyboard, DVD burner... It's got a lot.

http://www.apple.com/macbookpro/

-==============================-

Okay you two, listen up. If you compare Macs to PC with the same exact specs, the price difference is trivial. It's like comparing Dell to HP. You missed my point about Apple designing their own hardware. Yes, other companies manufacture the logic board... Look at the inside of a Mac Pro or iMac and tell me that they just buy that logic board and shove it in there. No. The logic board is built to Apple's specs. It's all about better engineering. If it weren't then why would Apple have the lightest, thinest notebooks? What about the iMac? How do they pack all of that computer into that tiny space? Exactly. As for security... I'm still waiting for someone to break into to my Mac. It hasn't happened yet. Did I say it was impossible? No, but it sure isn't as easy as breaking into a Windows machine. If you can't understand why Unix is more secure than Windows, then you have no reason to be making this claim.

So, you're going to take excerpts from a Mac help site to use them in this argument? I have a better idea, instead of taking excerpts from a Mac-only site, why don't you take a look at all of the questions posted here on Yahoo! Answers. Just look at how many more Windows-related problems there are than Mac problems. Make note of the severity, as well. How many Mac users do you see with virus and spyware problems? That's right. None. Most Mac problems are caused by the user, not the system. Most Mac problems are easily fixed, within minutes. You didn't mention that, did you? I was a PC user long enough and have answered enough Mac-related questions to know that I'm right and you're just an ass-speaker.

Mac to PC intriguing question?

Q. I have a MacBook Pro and I sometimes like to run Windows on my Mac to take advantage of all the software out there. When I am using the Windows on my Mac, does this open my MacBook to viruses that otherwise wouldn't be a problem?

But warning... Mac OS X is not as secure as you think

SECURITY
Mac OS X was hacked in 2006 less than 30 minutes, and within 2 minutes in a contest in 2008, and within 10 seconds in 2009. In 2008, Linux and Vista were not hacked until another day when restrictions were lowered. Vista was next, and then Linux. In 2009 Windows 7 fell shortly after the Mac but Linux was unscathed.
Macs are standardized with Cameras, if your Mac gets hacked, the hacker can turn on your camera with more ease.
Please Note: All OS's have vulnerabilities.

VIRUSES
Mac OS X has viruses (and significantly on the rise), a friend of mine has a virused Mac. As more users use Macs, more viruses will come out for it. Especially when users think "they are safe".
