wtf did i just read?

www.aiphone.com www.entryvue.com http://www.mobotix.com/eng_US/Products/T24-IP-Video-Door-Station etc. etc.

second on iei, they have several weather-resistant all-in-one keypads with built-in relay.

hard to tell without pictures, but it's probably the ir reflecting off the inside of the camera glass or dome.

agreed - you only need a capture card if you're using analog cameras, and analog cameras don't have a "bitrate". a bigger limitation for you will be the fact that analog video is limited to 30fps by ntsc spec (or 25fps for pal). you'd need to get into specialized high-speed cameras and capture devices to go beyond that.

not sure how a switch "doesn't support" cat6? the cisco sf302-08p is a good one to look at: it's got eight 10/100 poe ports, and two gigabit/sfp combo ports. you don't need to spend extra for gigabit on the camera channels, as most cameras have well under 20mbps bandwidth, and only a very few high-end cameras even have gigabit ports. you also shouldn't need full 15.4w on all channels (it will do up to 15.4w/ch for up to four channels, or 7.5w/ch on all eight) because even ir cameras tend to use 5w or less. as for the cabling, cat5e is more than enough for gigabit; cat6 becomes necessary only if you're going to 10 gig, and if you're looking for sfp support, i assume that means you're looking at fiber interconnects. cat6 won't give you any better noise immunity than cat5e; if you want to be sure, use shielded cat5e, as thewireguys suggests.

don't forget each of those is going to reduce the light transmission (a polarizer by up to two stops, or dropping the light by 75%), which will require a lower shutter, which will increase your motion blur. license plates are one thing because they're highly reflective and you can illuminate and expose for them specifically... illuminating the entire inside of the car is a whole other can of worms.

what is this "error"? what dvr software? you've given no useful information.

sounds like q-see's ddns service is having issues.

i looked up your other thread. honestly, a 3a adapter would probably be okay in the long run - 40w *max* doesn't mean it runs at the max all the time. but since you found a more appropriate one, it's all good.

that's just a tv. from what i can find (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2772920&CatId=), it has a/v, vga and antenna/cable inputs only. 40w / 12v = 3.33333a - so basically anything rated 3.5a or higher.

that's correct: blue pair for one camera's video, brown pair for another camera, orange pair for +12V for both cameras, green pair for ground.

cnb includes the same generic manual with almost all their cameras... i would guess it's a generic warning to avoid problems with voltage drop over long runs, or ground loops with non-regulated cameras. there's no problem running 12vdc over cat5e with these cameras - i have two of them running 200' over a single cat5e with no issues. they're very low current draw and so very little voltage loss.

if you have an nvr (*network* video recorder) then you need either ip cameras, or ip encoders to 'convert' the analog (bnc) video to a network stream. the cameras and encoders must also be supported by the nvr.

that all assumes it was a lorex system before. there've been a number of manufacturers that have used this type of connector for cheap package systems over the years... few of them use the same pinouts, or the same voltages. you may be feeding 9v into a camera designed for 5v, or sending power up the camera's video feed - even if it doesn't kill the camera and/or dvr, it simply won't work. numb-nuts is right, your best bet is to just pull new cables and install new cameras... if you're lucky, the old ones aren't strapped to anything and you can attach the new cables to the end and use the old ones to fish the new ones through.

msrp for the 4-cam vigil mvr is about $1900... couple hundred less if you go with the cube case (mvr is nice because it can run directly on 12vdc, handy if you need to deploy with non-grid power). vigil does give you the option for analytics, as well as many other features, if you ever need them. vigil does its own motion detection, vs. relying on the camera, so you can configure it to record constantly, with separate on-motion and on-alarm record options. for example, you could have a camera record at 1fps constantly, and kick up to 10fps if it detects motion, or if the analytics triggers an alert, or on external alarm input. all these options can be set to operate on a schedule as well.

pelco esprit is the way to go. not cheap, but will work forever.

you can go standalone for fairly low-cost, although features like remote alerting/snmp might be hard to come by. if you want something more robust, and substantially more flexible, take a look at this: http://www.3xlogic.com/prod/983/mvr-series-micro-video-recorder. i don't see it right now, but i know this has been available with an internal five-port poe switch, so you just plug the cameras straight into it. video can be accessed via remote client, and because it's a windows pc at the core, you can get *full* control of the system via rdp, vnc, logmein, or any number of other remote-desktop/remote-support systems. you can use vigil vcm (vigil central management) app to monitor health of systems and cameras and alert you of camera outages or connections being down, and any number of snmp agents or even just windows' own snmp support. for cameras, you can look at dahua - there are some good models at very good prices that are compatible with vigil (depending on how suitable they are for your particular needs).

you get what you pay for. buy a cheap ptz, you'll get weak construction, short life, and poor image. if you're near salt water, that adds a whole other level of corrosion concern. you won't usually find ptz's bundled with controllers, because there are so many different control options. you can run 100+ cameras off one controller and nobody wants to pay extra for a controller with every camera. many dvrs can control ptz cameras as well, which would make a bundled controller an unneeded extra expense.

they're actually dual-voltage cameras, so you can use 12vdc *or* 24vac or just about anything else in between. they're also very low power consumption, about 2.2w, which is barely 100ma at 24v or under 200ma at 12v, so as long as your power adapter has sufficient current for all of them, you should be fine.

We are going to have to change Lenses. what a shame... maybe you should send me that one, it would look pretty on my 40d. that's an l-series, too - canon's top line.

every time you hit pause on playback, you're looking at an individual frame. a dvr that has "frame advance" will move one at at time. or playback your exported video in a player that allows you to do frame advance. most video editor software will do this.
