Well, when it comes to CCTV cameras and security related products, it can be. But generally, buyer beware when looking at the specs offered by companies that seem to be offering “high resolution” at a low resolution price. Sometime you may not be getting what you think you are getting.
And how would you know?
Most casual CCTV buyers do not use a resolution chart with standard CCTV test monitors when setting up their systems. Most security and CCTV dealers and installers for that matter don’t bother either. The import houses in the united states know this, and often will change the spec sheets to reflect whatever is needed to sell their product to an unsuspecting buyer. In an exchange with another distributor, I was told:
We evaluated XXXX-Cameras every quarter going back 3 quarters as we speak. We ordered them months apart for a reason. “Just in case” one shipment was wrong, but 3 shipments being wrong spec? Not likely. We analyzed all samples using a Pelco monitor, and across three different resolution charts. It sounds pathetic Jason, but it is absolute fact, XXXX-Cameras intentionally orders 380tvl, Demands China insert 550tvl and higher specification documentation in the camera boxes. Their cost basis much lower than any honest seller, and its even worse than that. If you sell 540tvl, they’ll advertise 550tvl, sometimes 570tvl, even though the owner knows its crappy 380 stuff. Its this bad Jason, I called them out on it, the guy chuckled and simply says “everyone does it, get over it”
He goes on to explain how using this method the disreputable importer can reap incredible profits based on the “cheap” pricing for those supposedly “high resolution” cameras. They just want to move numbers. And usually you won’t even know.
Why?
Again, its unlikely you have a test chart on hand when you receive your camera, and the other part is the limitation of DVRs to fully utilize the resolutions that are now available from the good manufacturers. Security Digital Video Recorders generally have not yet reached the point where they offer as high a resolution recording as the cameras can provide. A machine that offers 704×480 recording resolution scans out at 360 lines roughly, not even close to the 380 line standard resolution model when tested with a CRT as an analog system.
Though a higher resolution will give the DVR better compression points, the differences are hardly noticeable. Soon however, a greater number of HDMI recorders will be available as processor speeds increase, and those who upgrade to the new DVR technology using their “old” 480 + Line cameras will find they have been duped.
Knowing which manufacturer is likely to be the most accurate in their camera specs is a good way to protect you, and talking with your distributor, or seller also can be very helpful. In my experience, I have found nearly ALL manufacturers exaggerate a little on their camera specs, but their is one which stands out in my view as the most accurate to date; KT&C, which never seems to overstate its camera specs..
In the end, a good relationship with your seller will find them looking out for you long term interests, and they will be able to guide you to what IS a true spec and which products to avoid, and how to get all the lines you’ve paid for.
NVRSystems.net has been launched giving DVR systems buyers another opportunity to examine the pros and cons of Network Video Recording in security applications. They can offer some great IP solutions, however, they prefer to take the “educated approach” and let the buyer beware with a proper understanding of what the might be getting. An item from the section called WHY YOU SHOULDN’T BUY AN NVR:
c) BANDWIDTH – This is the worst culprit. If you plan to deploy, say 16 mega pixel cameras on your existing 10/100 or 100/1000 network, along with your existing data flow, PLAN on kissing your network goodbye. You will SHUT IT DOWN and your business will come to a HALT because you simply can NOT support that kind of bandwidth. Anymore much more than 6 to 8 cameras MUST be on their own Network. How much will that cost? Depends on where you live but it can run from $600.00 up depending on labor costs, materials cost, etc. Let’s look again at some math: 16 Analog cameras, running 30 FPS at 4 CIF will need 16.48 Mbps of bandwidth ONLY if it is streaming the video OUT to a client user. If you are NOT streaming, then it will require ZERO bandwidth. The 16 1.0 MP cameras, 30 FPS will REQUIRE 83.20 Mbps PLUS another 83.2 Mbps if you desire to stream it out to a client application. Think that will cause a problem on your network? Just wait until your sales, accounting, purchasing etc. staff CAN’T process orders and paperwork, and we’ll SEE how happy you are with your mega pixel cameras. NOW. If that wasn’t enough, consider this, the EQUIPMENT you purchase to make this all happen, is going to cost you EVEN MORE…..and THINK about how much you’ll pay in additional ISP costs to stream that video.
Good to do business where you have a complete understanding of what you might be getting into. Its good to ask questions as well to make sure you get exactly what works for your Security System.
Our Dealers are now carrying full D1 DVRs which can record high resolution at REAL Time. This allows even more flexibility for your security system, and offers the high quality video expected with today’s technology.

On your typical “body” or “box” style security camera, the lens mounting appears to be identical to any other camera of the same type. On more than one occasion, I have had to help someone trouble shoot the inability to get a clear focus on their box type security camera when setting up with a new lens etc.. Below is a little explanation on which helps to clear it up. Continue reading C & CS Mounting
No longer are companies looking at video surveillance and monitoring as an expensive, non-revenue producing venture. As electronics become more miniaturized and affordable, businesses are taking advantage to help further reduce costly losses as described below. The following, demonstrates a couple of areas in which you (the business owner) have control over. Savings in these areas should be considered as valuable as the revenue which supports your business.
Industrial Covert Unlimited celebrates over a DECADE of online CCTV and security camera education and CCTV product sales!
