For those members here who currently have security cameras ....
Do you have them outside the building, inside or both?Both, but it depends on the location and what the client wants to record.
Is a system that is professionally installed for $3,500 really any better than a system that is $1,500 from Costco?
Yes and no. In my opinion it all depends on the end user, what they're looking to accomplish with it and what type of environment it's going into.
I've installed the cheap 4 channel Q-See & Night Owl DVR's that sell for under $200 as well as more expensive brands that cost $1,500-$3,000+ for the DVR alone. I've used PC based and embedded. I've also used cheap $30 cameras and cameras that cost in the hundreds. Is there a difference? Absolutely. However, I will say (in my experience) that some of the cheap DVR's these days can produce some decent video quality if used with decent cameras. The inexpensive DVR's also lack many features, but you may or may not be interested in them.
allanc, you also mentioned that you're not very familiar with what to look for in terms of features. The best advice I can give is to start looking at the spec sheets of different brands & models, then create a spreadsheet with the features that are important to you. Once the sheet is created you can start comparing systems to each other. Also, become familiar with the different types of compression technologies (H.264, MJPEG, etc.), framerates, and what CIF, 2CIF, HD1, 4CIF and D1 means. Note: HD1 does not mean high definition
Also do some research and learn what the specs mean with the different cameras that are available. There's some real overpriced crap out there, as well as alot of low priced crap. Lately I've purchased a couple dozen cameras made by CNB and have been very happy with them.
Take a look at Avermedia DVR's. They recently came out with a couple of value DVR's that I'm going to purchase within the next week or two. They look perfect for an upcoming project I have. Avermedia EH1004H (4 channel) & EH1008H (8channel).
