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.

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.

I need to buy an outdoor security camera system. Night vision and distance are a must. Need at least 4 cameras. Any recommendations? This will be my first security cam purchase so any info will be greatly appreciated! oh yeah, I'd prefer a reasonably priced system... Like maybe below $600 and still a good system. Thanks for the help 8-)

Hello

Peter that is the worst advise I have heard in a long time Costco, Walmart and online companies like Lorex (coscto sells lorex) sell very low quality cameras and often don't offer watermark so there images cant even hold up in court.

Giving advice when you don't know what your talking about is like giving direction to a place you don't now where it is, all you doing is wasting there time and in this case there money too.

The cameras from costco and walmart are used as nanny cameras that's all there good for.
Most IR cameras give you about 1/3 of the vision as advertised they call it "projected" distance now this had no coloration with what the camera will actually see at night.

A Varifocal (can change what the camera can see) lens with a good aperture 2 good examples are 5-50mm or 2.9~10mm. A fixed lens almost never works when installing a camera outdoors. Again to ensure you are getting a good lens and optics stick to name brands and avoid online retailers, eBay, Swann Lorex, Costco and Q see and other cheap no name products.

Also if you are buying good cameras get a decent DVR.


A good outdoor Camera will have

High resolution (520TVL or higher)
Good signal to noise ratio (S/N 49DB or 50DB)
A true Sony CCD (not Chinese knockoff)
Rugged enclosure to handle vandals and environments
At least IP 66 and a suitable temperature rating for you region
IR LED's to see in pitch dark: active IR rating not projected IR as projected IR has no coloration with how far the camera can see.
2 or 3 different sized LED;s 1 size LED one type of illumination means you either wont get distance or wide angle and you want both.

I would go with the VIS-56IR-2910
http://dealer.ascendentgroup.com//dvr-irâ¦

this camera will give you 110 feet of clear vision in complete darkness and great images by day its the on I recommend for budget customer who need outdoor IR camera.


Cameras that have high resolution, and great signal to noise ratio can reducing file size on DVR's up to 50% and offer better images.

Low budget Economical
ASC-520B21IR-36
Economical Infrared Bullet Camera
520TVL
see 25 feet outdoors
Fixed 3.6mm lens
35~-25C IP 66

Cheap option would never suggest a camera lower then this one
(still much higher quality then Costco, Lorex, Swann, Qsee, and other no name products imported from china)

ASC-380B24IR-36
Infrared Bullet Camera
380TVL

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that's 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. 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. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 2% which means they canât afford to offer good service or allow for RMAs (returns). 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.
