Q&A:

batstooge asked I would like to buy a wireless outdoor camera security system. Any suggestions?

I don’t want to spend a fortune, but I’m not cheap either. Does anyone know of some decent wireless systems with about 4 cameras that I can mount outside and view from either my TV, Computer, or a monitor that comes with the system? Any help is appreciated.

And got the following answer:

First of all, if you are looking for a good usable image you probably want to stay away from the offshore gunk being schlepped off on the geeknet and big-box stores.

There are a number of ways you can go, as for viewing camera’s on TV there are channel inserters available which will superimpose your video onto a channel on your CATV. Another method is wireless UHF transmitters, however the neighbours will also be able to see snippits of your video (Which may or may not be a good thing, depending on your openness)

Another method is to use a networkable DVR which you can access through your Local network (could also be accessable remotely if you have a static IP). If you don’t already have one, you will have to get a multi-port router for this to work. Cheap only 30 to 150 bucks.

You could also get a stand-alone surveillance system with a video switcher / sequencer or quad display. This will only record if you attach a recorder, but if you are looking to view only this could be the solution for you. If you take a look back in my answer history there was a similar question where I went into more detail on the differences between Switchers, Mux’s, Quad’s and DVR’s. I also wrote an article on camera’s awhile back, it is fairly old, however most of it still applies. There is more information which may help on my website at http://www.keepsafesystems.ca.

I hope this helps you out in your endevour.

———————————————————————-

The starting point of any C.C.T.V. system is the camera. Simply stated, a camera is a light sensitive device that converts particles of light into electrical impulses, however, there is a vast difference in the quality of cameras available to the consumer. Factors that differentiate the various cameras include whether they are color, black and white, light sensitivity, image resolution and image transfer technology. The consumer must also consider the inherent advantages and disadvantages in each of these different camera technologies and decide which features best fit their individual needs and goals.

In the past, color cameras have been both very expensive and lack-luster in their image performance, when compared to black and white cameras. New technology is now bringing the innovative technologies closer together in both the price and performance scale. The current differences between the two technologies are almost entirely limited to light sensitivity and light reactivity.

Light sensitivity is measured in LUX. The lower the LUX rating, the higher the sensitivity to light. It is important to keep in mind that even the best-rated cameras are limited by the technology of the day, as well as the visibility conditions present at the time of the surveillance. Although great advancements in low light surveillance continue to be ongoing, the image quality in a low light situation will rarely be up to the standards of daylight surveillance.

Color cameras, although much more appealing on the outside when compared to their black and white counterparts, generally offer less low light sensitivity than a black and white camera. The other advantage of black and white cameras over color cameras is its ability to “see” infrared light, which is invisible to the human eye. You can test this by aiming a standard television remote at a black and white camera while watching the monitor, the flashes you see are bursts of infrared light. The advantage of this becomes apparent in the ability to light up a dark area with infrared light, thus making images visible in almost pure darkness. With the color camera the area will appear unlit, however, to a black and white camera, the area will appear almost like daylight.

The black and white camera‚s reactivity to the invisible light spectrum can also pose a disadvantage in certain applications. Infrared light, although not visible to the human eye, is found in abundance in many everyday situations. For example, when aiming a black and white camera at hot pavement, it will “confuse” the camera resulting in an unbalanced image. Professional grade black and white cameras often incorporate infrared cut-filters. These cut-filters inhibit the infrared light spectrum in turn decreasing the cameras low light sensitivity.

The C.C.T.V. Industry measures image resolution in horizontal lines. The higher the line rating, the clearer the image will appear. With this fact in mind, consider that all electronic components within a C.C.T.V. System, from the camera, to the VCR, to the monitor. These items are all rated in the same way. The actual resolution of the entire system will only be as high as the lowest rated item. For example, if you have a camera rated at 450 lines and a monitor rated at 300 lines, then the result will be 300 visible lines of resolution because the monitor is the lowest rated item in this example. Another point to keep in mind is that the line rating is “Total lines” not lines per inch. Therefore a 12″ monitor with a 300 line rating has a far better clarity than a 17″ monitor with the same line rating.

The most recent and predominant advances in the C.C.T.V. Industry are the changes in image transfer technology. This technology deals with how the camera takes light particles and converts them into electronic images. Without going into too much detail, image transfer technologies include the following:

Phosphorus Tube Cameras – This camera has low quality, old technology and is susceptible to “image burn”. Image burn is when intense light sources will burn themselves into the camera‚s light receptor resulting in the image appearing “memorized”. Although this is not a problem with modern day cameras, image burn can still occur on monitors. Tube cameras are also known for poor low light sensitivity.

C.C.D – Also known as “Chip cameras”. This camera is the most standard of cameras in the professional realm. C.C.D. cameras do not suffer from the problem of image burn and can incorporate various methods of signal processing, which offers a high level of flexibility to the installer.

CMOS Transfer Cameras – These cameras are very small and continue to get smaller as the technology advances. Although very attractive in their size, CMOS cameras generally do not offer the signal processing, image quality or low light sensitivity of the higher priced C.C.D. camera models. However, the technologies are slowly growing closer together to the point where CMOS cameras may eventually take over the Surveillance Industry.

The Surveillance Industry has continued to move towards the implementation of color cameras that switch to black and white, or even infrared in low light conditions. Although there are some models currently available on the market, the technology is not at a point where it is affordable enough to be manufactured on a large scale.

Gary asked What is a good home security camera system?

I am looking for an home security camera sytem that I could link with my tv on it’s own channel.

Any suggestions?
Trying to stay below $400, I could do any wiring myself. I live in South Florida so it gets to be around 90 degrees on average. Just a standard resolution in color. Night vision would be a big plus but not needed. If it could be directed to the video input on a receiver that could work also. Would want it to store recordings.

And got the following answer:

Analog, composite video? There are lots.

On its own channel? Some RF modulators can be expensive, especially if you want to select the channel. Easier if you just use one of the other video inputs that are not in use.

What is your budget?
What resolution are you looking for?
Will the video need to be recorded and stored? If yes, what surveillance DVR are you looking at?
Only one camera?
Is night vision required? If yes, how far does the camera need to see in darkness?
Does the camera need to be outdoor rated?
Does it snow where you live? If yes, you may need a housing with a heater unit.
Does it get REALLY hot where you live? If yes, you might need a housing with a cooling system.
Is the video signal to be wired or wireless?
Is there power available where you plan to install the camera?
Is the camera going to stay in one position or is pan/tilt/zoom control required?

You have not provided enough information for anyone to provide you a good recommendation.

herringchip asked what are the best security camera systems for businesses with warehouses & large property to secure?

would like info on the best and affordable wireless security camera systems. Need at least 4-5 cameras. Need wireless, outdoor use, night vision, and zoom features for plate and face identification. a large area needs to be covered (about 3 acres). However, I mainly need to survelence for parking entrance/exit, Cash register, and 2 locations of shipping and receiving. need to know how to relay feed to central computer which in some cases is over 1200 feet away from the camera feed. thanks!

And got the following answer:

It sounds like you have fairly specific needs. If you are looking for licence plate recognition, night vision and zoom features it is not going to be cheap and you should probably stay away from wireless solutions – particularly inexpensive ones.
As for connection to a central computer, this is typically done with a DVR (Digital video recorder) Through IP. Although there are some IP specific camera’s out there. Be careful on the equipment you choose as there is some pretty crappy offshore equipment out there. What looks good on a monitor locally may not look so good once the image is compressed and sent over the internet or LAN.

When you look at a system it is best to look at it as a whole. There is a term we use in the industry – crap in crap out. You may have the best the best camera but it doesn’t matter one biut if your recorder is crap. Same goes for the recorder, if you have a great recorder and really bad spystore camera’s you might as well be looking at a black and white TV in the middle of the bush with no cable.

I don’t know what area you are in, but there is some basic info on my website at www.keepsafesystems.ca you may want to contact a professional in your area.

ExtremeCCTV just came out with a licence plate night camera. It is quite impressive but by no means a Costco / home depot unit.

lax24freak asked I have a wireless security camera, is there a computer program so I can record it onto my computer as a video?

SVAT WSE201 Wireless Indoor/Outdoor Color Night Vision Security Camera System with Audio

I don’t want to go buy a VCR and record it onto tape. Is there a way to record the video directly to my computer…i.e. a program that will record from the camera?

And got the following answer:

This question belongs in the camcorder group.

William asked A good security camera system that i can view with my ipad wifi?

I need to hook up an outdoor security camera system but one that is also wireless. I would need to view it on my ipad as I am going away on vacation so something that doesnt need recharging would be the best

And got the following answer:

Hello

Here is a DVR that will work perfectly for you.

http://www.ascendentgroup.com/x4s.htm

Most DVR’s and cameras don’t have the ability to view from your i-phone, and you cant just download generic software all DVR’s and cameras uses different encryption , software, and compression so you cant use another companies software to view another manufactures DVR.

You want a DVR that has an app specifically designed to work with it like the one I am suggesting below.

What you want is a DVR a DVR converts analog cameras and as well as storing images 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 your house.

A good Analog DVR will do what you are looking for and not only display them but record them as well they will also allow you to view them over the internet from a Iphone or laptop.

X4S Remote Accessibility
View all your cameras instantly and remotely, and configure the DVR through internet using eitherbusiness in real time from anywhere in the world. MAC or PC platforms (smart phones too). This allows you to manage your

Many people have a misconception that IP has Superior scalability then Analog but with the advancements with DVR’s this simply isn’t true, you cn do up to 16,000 cameras each camera could even be from a different DVR and a different site.

And when you are using the internet to connect multiple sites together analog transmits over the internet faster with less latency using less bandwidth allowing you not only to view and monitor a situation real time but also effective control PTZ cameras.

What is the Advantage of IP?
Many of the so called advantages of IP simply don’t hold water in the real world, IP is mainly Hype and marketing and outside of a few niche applications such as 1 or 2 camera installs, where MP cameras are needed or large scale wireless projects which represent about 2% of the total CCTV market, IP has very few advantages compared to analog based on performance, cost and reliability. (yet all companies touting IP will often use MP cameras to demonstrate the advantages of IP)

IP video is more about marketing then it is about performance as larger companies like Bosch pelco Honeywell axis can change for both hardware and software and once you use there cameras you have to keep using there cameras unlike analog.

Also IP sounds great, plug and play, Better image quality, use existing infrastructure, who wouldn’t want that unfortunately this is often not the case.

IP cameras are based on CMOS
Analog cameras are based on CCD (usually)

A CMOS sensor is constructed using a array of pixels, but unlike CCD’s CMOS do not have a capacitor to store the charge for each pixel.The rows of pixels are activated sequentially rather then individually

In short unless you have perfect lighting a good CCD camera will outperform an equivalent CMOS camera.

File Size:
The smaller the files size the more images that 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 recoding storage time, how much you can back up at once, how fast it renders and searches video.

IP cameras have up to a 5X larger file size then analog cameras. (at same resolution) I have seen MP cameras that on 2MP resolution are over 300X (%3000) larger then our X3 DVR on a CIF image. This is an extreme case but generally speaking IP cameras have a much larger file size.

Most routers and switches are not designed to handle IP cameras they have enough bandwidth but they are not able to process the amounts of commands. (9 IP cameras 30FP is 230 instructions per second) standard routers have enough bandwidth (up to 1GB) but cant handle the amount of tasks (instructions) so frames get dropped latency is introduced and the effectiveness of other devices such as POS, printers and dats storage can be affected and compromised.

Don’t get me wrong there are some brutal analog cameras and DVR out there but If you see a good D1 resolution image such as Ascendents Hardware compressed you will not be so quick to join the IP bandwagon.

IP is a young and emerging technology and I have no doubt that in the future it will outperform analog cameras but its not a mature technology yet. Once we start to get standard IP platforms, get rid of license fees’ and existing networks have larger bandwidths then IP video will be a good solution, but until then analog is the way to go.

Make sure you get good cameras as well, Ascendent has the best IR outdoor cameras on the market and are about %50 less then Bosch while offering triple the distance.

Billy asked Where can I buy a wireless security camera system for exterior use?

I am interested in buying a wireless security camera system but I don’t know where I can find one. It’s not something I can just find at walmart. Any help is greatly appreciated.

And got the following answer:

WOW bad avice

You can take your advice from people who Google or a security professional who specializes in CCTV.

Peter Brissette: there is nothing new about the products on your website in fact there are many misleading statements. many offer 3G and IE connection.

On your website you claim:
4GB Micro SD Card for video storage (7 to 10 days)

Truth: a high resolution camera with the smallest file size will use over 15GB-30GB a day (with 40% motion) a 4GB card will give you hours not days.

There is nothing new about the products you offer they are lower then the average product out there.
There good for nany cameras but not for a security system.

the products you sell (except for PTZ) only fixed cameras which will almost never work as you cant adjust the view.

there is nothing bad about your products but they are not high end please don’t claim them to be.
They should mainly be used for nany cameras not for people who are interested in security (I don’t think you even have watermark so images wont hold up in court though cant confirm as your website has very little information and even less specs.)

Hello sorry about that

You don’t want to record 24 hours a day you want to record on motion so if there is no moment you don’t records this will increase your storage a and decrease the amount of video you need to look for.

Very few cameras offer true day night performance mainly companies claim but rarely deliver.

For night operation you need IR cameras or very good lighting I suggest the latter.

You want to stick with a brand for day night cameras such as Bosch, Ascendent, Pelco and honeywell

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-ir…

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
MSRP $110.00

http://dealer.ascendentgroup.com//ascent…

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
see 25 feet outdoors
Fixed 3.6mm lens
35~-25C IP 66
MSRP $75.00

here is a write up I did on CCTV a while ago hope it helps

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, it’s 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: Ascendent’s 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.
