Question: is there a on or off switch? I installed my camera and nothing happens and do I need to run a special  line different from my other cameras
Document: I've never seen a camera with it's own user interface before, but if you're going to run the line for this camera through conduit or in an area where it's not readily accessible (as you should) - then getting to the menu is gong to be a pain in the butt... requiring the dismounting of the entire assembly from the wall to pull the cord through.
Was concerned about some of the negative reviews and inaccurate information. Maybe this camera is being sold in different versions by different suppliers? I got mine from HQ-Cam and it shipped from Vegas. Ordered 3 more so I'll have more to write later on.
I've installed security cameras for a part-time living for the past 8 years. This is one of the best deals I've found in a while. Bought it in June '14 for about one-fifty and that is great for what you get. The only thing I found wrong was the focus and zoom labels are swapped. The silkscreen labels are wrong, but the adjusters work just fine. Realize that these are metal screws turning plastic gears and be careful.
I removed the optics tube from the CCD sensor board and inspected the optics assembly and everything appeared to be in working order. When I put the optics assembly back on the CCD sensor board I noticed that I was able to insert it into the collar about 2 mm deeper that it was originally installed. I again tested the zoom and focus and was now able to focus the camera perfectly at any zoom level.
So I looked all over the web for an affordable license plate camera and tried this one out.Let me say that the actual hookup was easy... however, the directions for zoom/focus configuration were non-existent/useless. I tried repeatedly to use the rubber toggle provided on the camera cord to zoom/focus and it did absolutely nothing (found out later toggle is actually used for the color/tint adjustments once manually zoomed and focused).
I've had this camera for over a year, and still haven't been able to get it to focus properly. Worthless instructions, you have to wing it. Although it comes on, the focus is absolutely terrible. I've obviously made it worse, but don't know how to get to work. My tech guy who has installed dozens of security systems, also couldn't get it to focus properly. It's pathetic!
We installed this camera at the entrance of our basement parking facility. It works very well. We can read all incoming cars' license plate, even for the car at 60 feet away.Afternoon of the day, the sun light causes glare on the screen, we finally figured out the top cover of the camera works to stop the sun light. The way is just to move the cover to more front.At night, we discovered to turn on the HLC feature from the camera menu.
This is a very good camera,the color is awesom,night ir verry good.better than the cameras i purchase over the last 2 yrs.Easy to adjust.zoom in very well from a distance to get a clear view.setup very easy fields of view great.-will purchase more.I have purchase many camers,by far this is the best one
I was able to install this on front gate Of my house. So far this camera is awesome for the price. Color video during daytime is awesome.infrared camera during night time operation is also Great. I was very satisfied with this purchase. It's  better than cameras I bought a few month ago for twice the price( I bought on eBay, whatever , i returned that one.)
For now my camera is up and working and adjusted to what I feel is it's optimum setting for picking up plates. I don't think I will be buying another.Update 3/24/14, Well here it is about eight months since I purchased this camera and it is starting to act up, no doubt I will have to replace it soon. I can see why the business I work for will not use cameras other than Samsung and Bosch.
Answer: do you have power going to the camera  and if no you need to power it  with the  power cable that came with it if you are using cat5e  to plug it in  the use  one set over wires top power it  there is a adaptor you can buy to do this
