I like a few features on all my cams and dislike a few features on all my cams. No one cam has turned out to be the perfect cam.
I like the reliability of my old Reconyx RC60 cams. Extremely expensive, but they work right every time, and have for many years. No flukes or flaws. The downside to the RC60 is unit size (fairly large), being powered by 6 C-cells that need replacing about every 45 days, not the greatest picture quality, and not the greatest night-time illumination distances. But on a scrape or trail, they work fantastic. Ultra-fast trigger and every setting is customizable, even down to the time delay between burst-mode pictures.
I love my old HCO SG550. Great little cam that runs forever on 8 lithium AAs. However, picture quality and illumination distances arn't great (pictures are fuzzy). Plus it is a red-glow cam. But they just keep running and running year after year. However, using the little plug in hand-controller can be a pain.
For a red-glow cam, it's hard to beat some of the Bushnell cams. I love the ones I have. Excellent picture quality, good night illumination, easy set-up, and so far, no problems with them at all. And they will run for a year or more on 8 lithium AAs.
I liked the picture quality (night and day) of the Uway NT50Bs. Love the very high number of burst-mode pictures it will take (up to 9). I liked having a good viewer in the hand-controller. But the plug-ins for the hand-controller and units have had problems. I also had problems with the NT50B being too sensitive. Hang one on a smaller tree and it will trigger with even the slightest breeze moving the tree. I've also experienced a high failure rate with these cameras, and none of them have lasted more than 18 months.
So far, I am seriously thrilled with the new Uway VH200B cams. I have several of them, and they seem to be a good compromise on everything. They are not overly sensitive, have a narrower field of sensitivity (so deer outside the picture frame can't trigger the camera--a real problem with many makes of camera), take excellent day pictures, good night pictures (if a tad grainy), and has quite good illumination distances at night. When pointing these cams into openings like food plots, I plug in a black-flash flash extender, and those things REALLY light up the night. With a flash extender, I can see antler characteristics on bucks at 100+ feet at night (amazing for a black-flash). The only downsides I've found so far is a fairly small internal viewer (hard to see detail), an inability to "look through" the camera lens to see if the camera is line up correctly, and a maximum burst mode picture series of only 3 per trigger. I guess you could also say having to run them with 12 lithium AAs is also a downside, but they will probably last more than a year with those batteries. But so far, these cams have performed flawlessly, and they are my new "favorite" cam, especially with a flash extender attached.
I've also been testing the new Uway U250B, a smaller retail version of the VH series. However, I am not as pleased with this unit. Picture quality is poor, illumination distances are poor, motion blur is extreme, and the internal viewer is so small as to be virtually unviewable.
