GrayMan,

What do you think about these cameras? I took a quick peak at the spec sheet and it made my brain mad. Im not a tech guy about these things, more car stuff really.

I'd be concerned about compatibility with monitoring software, since that seems to be a no-name brand. If it breaks/sucks/whatever, do they have anything even remotely resembling english-speaking tech support?

For the same or a little bit more, you can get an actual proper security camera, like an Axis M-series or an Acti cube... and I'd probably advise going that route instead of the nameless-camera.

I've got a couple of questions on this subject.

First, I'm looking at a system that will use a few basic analog box cameras. No PTZ, no zooming, no need to view camera images in real time. Do these cameras use a common communication protocol? One source says I can even take a camera like this and connect it directly to my TV. IOW, can I take any decent DVR and connect any analog box camera and have it work, or are there proprietary elements that prevent this from working?

Second question. If the DVR has RJ45 connectors and the analog camera has BNC connectors, can I just connect a balun to the back of the camera and run Cat5 all the way to the DVR?

Thanks.

First question: Yes, any standard analog security camera that follows the NTSC standard should work with any standards-compliant analog DVR (NTSC is the American video standard... PAL is the European video standard).

Second question: This one is more involved. Some DVR manufacturers use a non-standard cabling/plug set to either deliver power to their cameras, or get video back from them. If you power the camera at the camera-end, you need basically two wires to get video back to the DVR: one wire for the video signal, and one for ground. If your DVR is like some out there that use a non-BNC connector (some of the Samsungs use an RJ-11 connector, while other brands use RJ-45), you'd need to determine the pinout of their plug.

In other words, if the DVR has RJ-45 plugs on the back for "video in," you'd need to determine which pair it was expecting video/ground to come in on, and then wire your Balun at the camera end to deliver video on the appropriate wire.

You'd have to experiment a bit, but it's probably doable. Alternatively, go with a DVR that uses standard BNC connectors... I've yet to see an analog DVR deliver quality/features so good that it would make me want to hack up a bunch of cables to make it work.

I dont like any system that isnt HD, if the camera cant identify a face or license plate its use is limited.

also, lol at the swann...16 cameras but only a 500gb hard drive. Would only give you maybe a day of footage before overwrite. Also, that is a lot of wiring to run...a major pain in the ass. Better to get HD cams that are clearer so you dont need as many cams to cover a sector.

Qsee makes good stuff, but this one isnt HD.

Look for an IP cam system, they are usually HD.

There are lots of IR illuminator products out there. Which ones do you use/recommend?

I tend to use the wide-angle dome-type illuminators. Think about it... you probably want your IR to illuminate an AREA rather than one specific spot. I have been using the dome illuminators you see in these threads for a couple of years, with good results... and they're about $50 each.

I have another type inbound that I'm going to test... I'll post results when I have pics.

I've searched with no luck. Link or store to buy those?

I'm currently building a new home and all this security camera stuff is making my head spin, I want to pre wire to have the flexibility to use any camera, network, DVR etc. What type(s) of cable should I pull. CAT6, RG ???

I'd do Cat6, and lots of it. Seriously... don't skimp. Spend the money. At least one run to every location you'd EVER conceivably want a camera. That's every corner of the house, right above your garage, above your front door, above your back door, above your side door, on each side of the house, and in every room you might want a camera (entryway, foyer, kitchen, garage, baby's room, etc). Terminate all of those runs in a central closet in the house (that will become your wiring closet). I'd also want a few runs of regular 120vAC to junction boxes under the eaves, for placement of either floodlights, or IR illuminators.

Ensure that the aforementioned closet has a solid door/frame, and has a vent in the top of the door (I might even recommend a fan with that vent), and either make the frame an inch or two too tall, or plane off an inch or so off the bottom of the door (if it's wood), just so air can flow underneath. You don't want all the switching equipment and CCTV storage to die from heat. Keep that door locked, so any smash-and-grab burglars will have to literally pry/chop their way into it if they want to steal your DVR.

The hard part is pulling the cable... and it's damned hard if you wait until after the house is built. Have them run the cable WHILE YOU"RE BUILDING.

You'll thank me later.

In the second picture is the bright spot the IR illuminator? The camera & illuminator are mounted away from each other then? If I were to get separates the camera would not have to be the ICR type?

Sorry for the trivial questions, but even after reading the thread my head is still spinning. I'm still in the looking process for a system but get confused by all the technical terms. I want a set up that will give me quality video day & night, but don't really know where to start. Do all systems have a DVR style center or is there other ways?

Correct. The illuminator is mounted in the center of the porch, and the camera at one end.

And ANY day/night camera should have an ICR (unless you're using a dual-imager camera like an Arecont, or Mobotix). If it's a "day/night" camera and it does NOT have an ICR, I wouldn't buy it. It's likely giving you "night vision" by slowing down the camera's shutter speed, which sucks for anything but a static scene.

OK, I'm finishing up my new home and I need several security cameras. First off, I prewired both Cat6 and RG59Siamese cable to every possible location so I have the option of any type of camera. I'm looking for high resolution, exterior cameras that must be able to hold up in a harsh, salty, humid environment. I need a couple of long range cameras, a few closer up porch cameras and would like good night vision. My cameras mostly face east west so they will experience direct sun to extreme shadows. DVR and any other devises required are also needed. I would like to keep camera costs to about $200 each and need approximately 15. I could use some unbiased recommendations as there are hundreds of cameras on the market and I know nothing about them. What advise does the hive have?

I doubt it can be done for that price-point.

Here's why I say that.

Network cameras run at least in the $300+ range... and a good deal more for anything decent... especially weather-proof outdoor cameras. The most weatherproof cameras I've ever seen are the Mobotix line. The housings are almost entirely composite, all the screws are stainless, and they have no moving parts. They have those things mounted on mountaintops... here is a mobotix camera mounted on a 16,000-foot peak in Nepal, viewing Mt. Everest. It's run off a solar panel, and the temps there hit minus-30 Celsius... it's the highest webcam in the world.

The Acti cameras are also pretty weatherproof... but you're looking at $5-600 each for their outdoor domes, and you have to seal them. Your location says Florida; I don't see too many cheaper cameras holding up to a moist, salty, corrosive environment for any great length of time.

You also mentioned long-range... which means lenses. Cheaper cameras aren't going to have sufficient zoom, and most of them probably won't even have the option of changing lenses.

The good news is that you can probably cut down your number of cameras by using some higher-megapixel models, and placing them strategically.

Depends.

Analog cameras will give you video... but the question is whether they will give you USABLE video. If you choose your mounting locations well, and use the appropriate cameras and lenses, you might do fine with analog. Focus on choke-points, entry doors, driveway entrances, etc.

Broad area coverage with analog cameras is rarely good enough to ID anything, beyond "yeah, there was a guy walking around... and he drove a blue sedan. Can't tell you what make/model/etc... and the guy was probably blonde"

Megapixel stuff simply puts more pixels on the problem, and give you a higher-res image. Analog is limited by the NTSC video standard.... it will never get better/sharper. In short, you will have no upgrade room.

Then again, you're probably limited by your budget... so the sky is clearly not the limit.

I currently run 2 Acti TCM1231 cameras. One is as perfect as ou can get. The other has a lot of false activations. IThey are both used indoor now. I'm on the hunt for software to take full advantage of the images.

As far as anybody wiring their house during construction...run conduit. I rane 1 1/2" conduit to each room. I have repulled wires to to areas because of upgrades in the cable and for expansion. Label each conduit and leave them empty until you need to use them.
