Dvr 2000 Board other use software
rory replied to quante's topic in DVR Cards and Software - PC Based Systems
So your basically saying the remote software is no good? Dont know, I think like thomas said, unless you had the 4 channel card which looks like it would work with generic software, you may be stuck with what came with it. Does it use BNC Connectors, or a Pig Tail? Also check out this post. http://www.cctvforum.com/viewtopic.php?t=2021 Rory -
Dvr 2000 Board other use software
rory replied to quante's topic in DVR Cards and Software - PC Based Systems
Is the software is not working? Do you get a driver error? Or do you just not like the software? Rory -
You wont find that model online, the particular model number anyway, they resell in wholesale only. Ive been looking online for it also, but cant find it. I may talk to someone about selling it so at least there is a source somewhere for it, as it is a decent standalone DVR with good features. It appears that mostly installers are selling them. Best image would be obtained from seperate Infrared, such as the Extreme CCTV UF100, or if it is a longer distance, UF500. They have different beams and filters. Most BW and Day Night cameras will recognise the 840nm filter, which is a slight glow, if you want invisible light, 940nm+, you would need a camera specifically for that, Sanyo has some, as does GE and ofcourse Extreme. The Spec sheet would normally say so, such as the Spectral Response, or IR response. What I have at my place, simply color cameras where I have some outdoor lighting at night, and BW in the low light areas. If its pitch dark then IR is required, or Motion Lighting.

NUVICO NVCC-W27IR30N D/N CLR BULLET any good ? i'm 1st timer
rory replied to K435's topic in Security Cameras
i agree with Sal, the camera posted is only a fixed lens with electonic iris, no IR Cut Filter, and also dont really go by the IR specs, they are never that much, especially 30LEDs, you are lucky to get 30-40 feet outdoors. PS. You get what you pay for ... -
yeah, i get a couple hours here and there

yep, missed it the first time sorry: Boost and Trim Automatic Voltage Regulation (AVR) http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=BR1500I

Wide Angle is good for Observation and reaction to a situation as it happens. Okay, an example would be a night club, we have a narrow lens at the entrance, to get a full facial shot, color of clothing, etc. Then the cameras around the club are mostly BW and wide angles, 3.6mm. Its enough to make out the person to a degree, not valid in court though, but match them up with a better shot from the front entrance camera, then get some more evidence on them like witnesses, finger prints, etc. Takes a little investigation. another example would be a marina with a wide angle shot, there is no way to make out what is what, at a long distance, but the person manning the cameras can see something is there, then either use an additional PTZ to zoom in on that, or call for additional security or police assitance to check out the incident in person. Typically when you go over 50' away from the FOV you loose any kind of valid recognition. Ways to get around such situations in your yard, would be to use Alarm Beams, and tie them into a PTZ, set up presets for the PTZ, when a certain beam gets triggered ,the PTZ Zooms into that area. Ofcourse its not a cheap method though.

It doesnt appear to have Automatic Voltage Regulation.

Cat 5 (Twisted Pair) vs RG cabling
rory replied to chewingyu's topic in Video Transmission/Control Devices
Punch blocks are used for telco wiring.

Cat 5 (Twisted Pair) vs RG cabling
rory replied to chewingyu's topic in Video Transmission/Control Devices
Multi building applications as you suggested, I would use Active Transceiver hubs with Passive Transmitters (or active Transmitters if further than 3000' distances or the budget is willing), such as the NVT gear for example. Use punch blocks or make your own using terminal strips. Run cat5 if possible, though cat3 multi pair bundles would be useful for future add-ons. Power locally for each building. If you have alot of money, look into Fiber. -

be prepared to loose some quality over longer distances, without an amplifier. -
Cat 5 (Twisted Pair) vs RG cabling
rory replied to chewingyu's topic in Video Transmission/Control Devices
RG59 can go approx 1500', RG6 approx 1800'. But basically you loose quality over 200', in fact with any cable, without an ampifier, which active is when talking about cat5/UTP. There are also Amplifiers for Coax, and NVT sells a couple of these, 8 and 16 channel versions. Rory -

In the CCTV industry, typically a "cheap" product means less support, lower quality, and less warranty. But there is a market for everything . ..

Speed dome is a PTZ .. just a name the chinese call it Basically there are Fixed Dome Cameras, and then there are Pan Tilt Zoom Dome cameras. Some cheap versions of Domes exist where they zoom digitally but have a movable pan, these are PT only, and are typically OEM or found in places like kmart, etc. however even some of the big brands have a version of this also, such as GE Security, but they also have a large line of real PTZs. Dome enclosures for PTZ cameras will be larger due to the movement of the camera within the dome enclosure, while Fixed cameras can fit in smaller dome enclosures, and if they just have a fixed lens, not a varifocal lens, then they can fit in even smaller enclosures.

Also visit www.extremeCCTV.com and read up on some of their IR gear, they are not cheap but a leader in the Infrared CCTV industry.
