Security Camera System Needed - Any Suggestions?




Char Char


I need a system that is for the outdoors (weather-proof), it needs to have at least 6 cameras. The cameras are going to be spread across 4.5 acres, so I need them to be either wireless or be able to buy a large qty. of cable to have the cables run underground to the main control panel. I would like for the cameras/control panel to be connected to the internet or our computer network for monitoring over the internet. I have read a little bit about the DVR/control panel the cameras hook-up to and as far as the storage it has I don't really care, as I will just erase the previous video, so I would say just enough for a day or two of recording.

I am new to cameras so this is why I am asking on here. If you could please provide a name of a company, a link to a website or a product/kit name that meets these requirements, that would be great. Thanks.

Hello

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance take cars for example. 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.

One of the best posts ive seen on yahoo many are brutally incarcerate or blatant advertising attempts by online retailers: Caoedhen is dead right and one of the few people who understand CCTV and has worked with it for a while so many people buy a system online and think they know what there talking about.

ApexCCTV does not sell high end products and there IR cameras are not high quality they are from china and Taiwan and most have 48DB signal to noise ratio which is 100x more noise then a good cameras will have resulting in lower image quality and a larger file size on DVR`s (golf cart)

ApexCCTV standalone s are decent quality as they are made by avtech who makes great DVR`s for the residential and low budget market but not a high end solution by any means.

Apex CCTV PC based DVR`s are powered by either Avermedia or Geovision which are not high quality and there marketing greatly exceeds there products features an ability,

back to your question:

95% of all wireless cameras are compete junk and any wireless camera under $400 run on 1.2 or 2.4GHZ and don't offer encryption. This is bad for 2 reasons one the signal can easy be jammed, with a laptop you can actually hacked video feeds so a criminal can use it to spy and know a good time to target your business or home.

Now one option for wireless is using commercial IP radios which are basically wireless routers on steroids and can offer distances up to 40km of wireless with military encryption, this is not a cheap solution but neither is digging a trench. using these radios not only give you a security infrastructure but also communications infrastructures as well for internet and other purposes (LAN network)

Good radio company

And yes you can do over 30 km no problem with these radios so 4.5 acres is easy to do. these radios are used by US military and I have done projects with them as well.

now in order to use this wireless network to distribute video you need to buy IP cameras which are similar to IP cameras only they transmit video over networks instead of a cable.

The company I recommend for CCTV products is Ascendent Technology Group they have a large product line and offer better products then Pelco Honeywell and Bosch and are about %20 cheaper and in my opinion have the best IR outdoor camera line up.

For an IP I recommend uses Ascendent`s IP servers that have a hard rive built in which does 3 things. Allows you use any analog camera and convert it into an IP addressable server. Allows you to distribute video over the network and has an HDD in it so that if the network goes don't or your NRV (network video recorder) goes down or gets stolen you have data redundancy. some companies use SD cards but to be honest that is quite useless low frame rate and only hours of recording.

Also again Caoedhen is dead right you want more then 2 days of recording I can`t tell you how many times people have wanted to look at video up to 2 months and have done projects where they keep video for 3 years. I would suggest no less then a week of recording.

As far as cameras there are many types but for outdoor cameras you typically want IR cameras.

Ascendent has IR cameras that go from 50ft to 10km yes 10km longest in the world.

If you talk to Ascendent and give them a diagram or layout they will design a system for you for free as long as you use there product. They will even test the tranzeo radios and make sure they work so they can send you a completely configured system.

I have used them on many installs and the odd time I received a defective unit they took care of me ASAP and they have great technical support.

Lauren and dunbar if you don't know CCTV products please do not give people advice.

Lauren , Every single one of your posts relating to security cameras advertises spytown which is blatant disregard of posting rules.

Spy-town products are low quality and will not meet the needs of most homeowners, and will definitely not meet the needs for a business such a hotel. not to mention you cant tell the quality of a product from an online store unless ypu have seen them working or if they have a demo you can connect to.


and Dunbar those are webcams and are not used for security purposes as they are low frame rate, low quality and dont have water mark so the images wont hold up in couart not to mention if your internet goes down you have no security and webcams are used for live viewing not for storing the images.

There cameras are not high resolution and have a low signal to noise ratio resulting in larger file sizes and lower quality images. not to mention they only do CIF resolution for the recorders which will not allow the user to zoom in which if you had read his post he would like to do.

You either work for spytown or you do not know a thing about CCTV most likely both and quite frankly I am sick and tired of people misleading others for there own benefit.

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.

I have done projects that required cameras to stream over satellite and cellular networks and the only DVR that could provide the video streaming was Ascendent Technology Groupâs X3 DVR. To give you an example of what a good DVR should stream like, below are instructions on how to connect to Ascendent's X3 DVR using Internet Explorer.

Instructions on how to connect to Ascendentâs DVR with Internet Explorer:

1) http://connect.ascendentgroup.com/ (Must be Internet explorer)
2) Install active X control
3) Hit âConnect)
4) DVR type PC
5) DVR code SITE-100
6) User ID Demo (case sensitive)
7) Password demo (lower case)
8) Hit extend config
9) IP address: 24.66.224.223
10) And hit connect

Again I recommend going with a PC based DVR but if you don't want to spend the money I suggest Ascendent's AVP-4120 DVR or Pelco's DX-4000 as they will allow you to view all your cameras instantly from anywhere in the world using either IE. The AVP-8240DVDUSB will also allow MAC platforms as well as PC to remotely view cameras and it uses the new H.264 codec but no standalone will offer the video streaming or performance a good PC based DVR will.
