Home surveillance system - what's neede? DVR/monitor/camera(s). Where find QUALITY & inexpensive products?




tlc289


I've priced a base system (1 camera with infrared capability / 80G DVR / labor) for $1100 w/ a local security company. It jumps up to $2200 for additional cameras and higher-functioning DVR (160G). Can a regular man install this sort of system?

Any and all information is appreciated.



Answer
Yes, I've installed two different digital video recording systems myself, bought the PCs from the local computer store, bought the PCI cards on-line and bought used CCTV cameras off eBay, bought the wire and connections at a local electronics store. They work like a champ.

The advantage of PCs is that the image is already digitized and I can monitor and review over the internet from another location (securely).

Approximate cost: New PC: $200 (open-box store PC returned by a previous customer, works fine), new PCI card: $29, 4 used CCTV cameras from eBay $80 ($20 each), wire and connections I didn't add it up but may run something less than $100 unless you want really long lines.

You cannot beat the quality and price of used CCTV cameras off eBay, although, like anything else eBay, you have to buy things that work. A few CCTV cameras I bought didn't work. Not knowing anything about cameras, I opened them up anyway and resoldered loose connections and they worked!

My second system has a similar PC except I bought a nicer PCI card for about $250 and have indoor/outdoor IR (night lighted) cameras that cost around $100 each.

They both have been running fine for over a year so far. And I'm not a security or PC expert but have learned a few things along the way.

Security camera / dvr advice for large retail shop.?




Ryan C


I'm having a the toughest time choosing security cameras and DVRs for my retail shop. The shop is fairly large (5,500 sq ft), I would estimate I need approx. 10-16 cameras (depending on the deal). :)

I would like them to have the ability to record audio as well as video, and I would like to be able to view them remotely anywhere with an internet connection as well as the ability to fast forward, rewind, pause.

Costco looks like they have some good deals but their systems (clover, lorex, q-see) don't have many reviews online to be able to chose the best system.

Price is definitely a factor I'm just looking for the best bang for the buck.

The main reason we are installing the system is to watch employee performance while we are gone IE to make sure they don't ignore customers for a book etc... secondary would be watching employees and customers for theft.

Any help on choosing a DVR / Camera system would be greatly greatly appreciated as I've been looking for weeks and am horrible at this stuff.

Thanks in advance!
Sorry one more question. For a shop my size would it be better to have two 8 channel systems rather than one 16 channel so I wouldn't have to run wire as far? or would this be a pain in the but to view maintain etc.?



Answer
Hello

I would recommend going with one 16CH DVR system over 2 as it will be less maintenance and you can view all of them using IE at once on the same window. Also you will generally find it more cost effective to buy one 16CH over two 8CH. If you are interested in the viewing your camera live 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.

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.

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.

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, 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.

This makes a great demo as it is up 24/7 and camera 1 is a PTZ camera which allows you to Pan Tilt and Zoom in real-time over the internet using the controls located to the right.

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 DVR or Pelco's DX-400 as it will allow you to view all your cameras instantly from anywhere in the world using either IE the AVP-4120 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 a good PC based DVR will.
