What is the resolution of the cameras I am looking at?
Fact:(typically you should look at 480 tvl's or greater.
Many large stores are selling cameras with 400 and 420 lines of resolution which is poor quality. Professionals don't even carry such low resolution.
Is someone offering "free" wire? Yes/No
Consider: Do you get free house wire when you buy a circuit breaker?
If you are going to all the work of installing a good camera system you should be using the proper wire. A surveillance system is only as good as it weakest link. Free wire is almost always cheap black speaker wire.
Also you will either have to drill a really big hole to get the connection ends through your walls or cut them off and re attach them once you get them through.
What is the size of the lens that is being sold to me?
Consider: Most big box stores sell 3 mm lenses which are ok for some application but not typically the best choice but they are cheaper. Most stores advertising cameras don't even tell you in the advertisement what the lens size is.
Am I being sold CMOS or CCD Cameras?
Consider: If they are CMOS it is because they are cheaper and most people don't know they are lower quality so they make good advertisements.
What is the recording Recording Frame Rate of the DVR?
You should have 30fps x the number of channels
Are you being sold "wireless cameras"?
Consider: you will either have to charge batteries every day or install electrical outlets beside each camera. In essence you are getting low quality wireless images and yet you still need to run electrical wire. Proper RG59 cable comes with video and power all on one cable for wired cameras: wireless interference not included.
Does the DVR have remote monitoring for your phone or computer?
Most systems do have this feature and it is not something that is special anymore.
Customers often ask us about CCTV resolution (the recording quality from CCTV cameras). Naturally a customer wants to know how clear the video resolution will be from a system before making a purchase decision. Television specifications (which CCTV uses) the highest resolution that can be captured and stored is 704 x 480 (NTSC for the United States) and 720 x 576 (PAL for Europe). This resolution is knows as D1 resolution. A high end CCTV recorder is capable of recording at up to D1 resolution. Again, this is the highest resolution available to record on CCTV systems. This is why at this time the highest resolution cameras we sell are 550 tvl. Current analog DVRs only support 540 TVL so don't waste money buying a 700 tvl camera as great as it is! 540tvl is going to give you a great picture. If someone is telling you something different, they are mistaken. Many stand alone recorders are advertised that they can support real time recording which is 30 frames per second, but if you read the specification of the DVR, they are recording at CIF resolution which is 352 x 240. On the other hand if you are going to buy 380 tvl or 420 tvl cameras you are wasting your time installing them. If you feel that you need a higher resolution please let me know and I will go over other options with you.
These are just some of the questions you need to ask. I encourage you to shop around and call me. You will not find better quality for a better price.
Questions I have recive by email and my response.
Hi, I am interested in a 8 camera system for my home and would like to know how much the install would be if i did 50% of the work with you, is this an option. The only reason I ask is because I watched your videos and thought with your tool lending program I could do the job but with your assistance? Thanks
I am going to be making a video shortly to explain this to people better, however take a look at this. http://www.wintroniccomputers.com/wintronics/viewProduct.jspa?product=c35fee022c9939e3012cc7c3d3860076
$479.99 for a 8 camera system. I don't have a 8 camera package that price and here is why.

D1 CCTV resolution is 704 x 480 pixels and is the highest resolution the CCTV system can record at. High end digital video recorders offer this resolution and only the highest end recorders can offer D1 resolution at 30 frames per second recording. CCTV Cameras Pros offers a PC based system that can record at D1 resolution using real time motion video (30 frames per second). This system can be found here: D1 DVR computer.
CIF CCTV resolution is 352 x 240 pixels in size and is one quarter the resolution of D1. This resolution is typically used by mid level stand alone DVR recorders when recording real time video. It is also typically used by higher end systems for remote Internet viewing (as streaming D1 video for multiple cameras uses a lot of bandwidth).
QCIF CCTV resolution is 176 x 120 pixels in size and is one quarter the size of CIF resolution. This resolution is typically used for remote viewing from a mobile device (cell phone).
As far as the installation is concerned because of my insurance I would not be able to have a customer work with me. That is why the customer does what he/she can due, then I do the other part. Installing that many cameras on the inside of a finished home is a lot of work no doubt, I often do these jobs while homes are in the construction phase. Installation on the outside is usually what people due on a finished home.
I think you can see from above why my systems are better. I am not competing in the “cheap market” however I give a great price when the customer compares my product to something that is in the same league as what I sell. This is why many people buy a package and install one or 2 cameras at a time when they can, saving money if your not in a hurry. Another point , I always favour wired cameras, however there are cases where you may integrate some or all wireless cameras into our dvr. With this said remember that wireless would only be an option where there are power outlets already installed. To get high quality wireless you have to integrate a high quality transponder with the dvr or pc and use good cameras. the systems you buy in the store are not going to give you any quality. I am also able to order in higher end wireless products.
