    Thanks Cooperman,

     

    I saw your earlier posts about len sizing. I'm looking for a DC-powered AI lens. My application would call for a focal length of around 5mm (at least with a 1/3 lens), so I'm not sure how that would translate to 1/2. I've noticed that the varifocal lenses are more-or-less the same price as a fixed focal lens, so I'd probably be looking for something in the neighborhood of a 2.8 - 12mm (again, I don't know how that would translate to 1/2")..

     

    Do you have any specific recommendations for a CS mount 1/2" AI varifocal? Will consider getting an adapter for a C-mount lens.

    I was thinking that a 1/2" would be "better" than a 1/3", such as the VCB-3384 (hey, I'm an American ). Assuming I can find a decent lens, would a basic 1/2" camera have better performace (e.g., resolution, contrast, low-light image) than a 1/3" camera?

    I'm currently looking at the Sanyo VCB-3524. It will be for outdoor use, so I'll need to addd a housing and AI lens (probably fixed at 4mm).

     

    Questions:

     

    * Is this a good camera? Anyone with direct experiences?

     

    * What other high-quality options are there in the same price range for an outdoor application?

    '~' = Approximately.

     

    Rory, what camera do you recommend for the following purpose:

     

    * Outdoor (weather-resistent and auto iris). Will consider a separate housing.

     

    * Day / Night (nice to have color during day and B&W at night. No need for a built-in IR illuminator -- will use either motion-activated floods or separate IR illuminators).

     

    Like you, I'm also into quality (on a budget, regretfully). Ideally $200 +/-

     

    I'm still trying to understand how to configure a remote-controlled varifocal lens through a DVR, but a feature like that would also be nice, if possible.

     

    To get an idea of what's available on the high end, I'm currently looking at the Vicon VC565DN, which is beyond my budget, but looks interesting.

    Yes the 1/4" x 1/4" works for the F connector just fine (I did 2 of those today).

     

    I also figured out some cuts for the RCA that appear to work: 1/2" x 3/8" (the latter being the exposed center conductor). However, rather than pushing the braid back over the outer jacket (as you do with the F connector), I found that scrunching it up 1/4" back from the exposed center conductor seems to work best.

     

    If I don't get any responses from T & B or Sargent next week, I'll have to experiment with the BNC cuts. If I have success on either front, I'll post the results here.

    I haven't yet used the BNC connectors, but I have some RCA connectors (for RG59) that fit the compression tool. However, I've had spotty success with the RCAs, mostly because I really don't understand how far back to cut the cable jacket and how much center pin to expose. From the looks of it, you have to expose a longer center pin with the RCA than you would with an F connector.

     

    The RCA connectors aren't cheap, so experimenting is expensive. It would be out of the question to experiment with the BNC connectors, at $5 a pop.

     

    I've sent emails to both Thomas & Betts and Sargent. I'll post whatever information I can get from them on this topic.

    Each camera has its own cheesy little power source. I plan to upgrade to a single panel, but ... .

     

    Admittedly in the current setup, I have power cords mixed in with the video cords. (Think snake pit from Raiders of the Lost Ark.) I know better, but it's interesting that the problem is only with the older cameras.

     

    I've been experimenting with CCTV for years -- sort of easing into the technology and testing it as a "poof of concept" before investing further. The "rolling lines" problem is only with my oldest (and cheapest) B&W cameras. The most noticeable problem is with my first camera: a five-year-old B&W ProVideo bullet that gets the most direct sunlight during sunset.

     

    Rory, I'll troubleshoot the cameras as you suggest and get back with the results.
