Color CRT Monitors
normicgander replied to normicgander's topic in Installation Help and Accessories
Until recently the system was on line power. The IT dept installed APC dual conversion UPS units for the entire system. However, appliances/equipment in general, especially TV/mon sets, use switch-mode power supplies which provide regulated DC to the vertical and horizontal circuits. One would think a CCTV grade monitor would employ good power supply circuits, but I could be wrong. -
Color CRT Monitors
normicgander replied to normicgander's topic in Installation Help and Accessories
Hey Rory, The monitors are GE Security models MVC-19HR and MVC-15HS. The rep is looking into this matter. I think your numbers are dead-on, but I needed to inquire. The monitors are also cycled down for 5 1/2 hours a day. Thanks much... -
I like the 3-piece from Cambridge or AIM 27-9100. They take more time to terminate, but are more robust in the long-term. The pin is mechanically bonded to the center conductor, which makes a better electrical connection. I do keep a few twist-on types in the box too...

ak357- Don't be confused by the NTSC broadcast standard and CCTV cameras which are compatible with NTSC, but can exceed the 4.2 Mhz bandwidth limitations in NTSc analog broadcast. The NTSC standard has a fixed vertical resolution of 525 lines. However, there are 42 lines (21 per lines field) used for things such vertical blanking, VITS and VIRS, closed captioning etc. This means there are about 484 active vertical scan lines. As for horizontal TVL of resolution, for any camera or system, it's a function of bandwidth mentioned above. There are cameras that have up to 1000 TVL but how would we practically record the signal (bandwidth)any how? (especially with todays low res DVRS) Basically, the increased bandwidth of camera costs alot more money because of the increased complexity of the amplifier circuits in the camera. This includes a high slew rate amplifiers, with fast response times (very low over/undershoot distortion), which allows the video signal to transition from black to white and vice-versa, thus allowing the camera to resolve finer details. This is difference performance between the circuit in a cheesey board camera and broadcast camera. But the board cameras get the job done for the right applications. I did look at the 540 TVL cameras, Bosch, Panasonic, JVC have them. The pixel density on the imagers has increased on the 540 TVL cameras. The bosch LTC 0495 has spec of 752x582 pixels. DSP and improved amplifier design must also play a critical role....

I guess I'll chime in on this one.. I just love (pun) the conspiracy Theories. Recall TWA800 when the idiots said it was a Navy missile. Can you just imagine several hundred Navy folks on a ship keeping that a secret? It's just insane. The issue with why 911 occurred is because the world is full of evil people with no respect for life. That being said, why it occurred is multifaceted. The US was somewhat a sleeping giant (again). Was it intel failures? Yes. Was it a lack of suitable FFA airline security program? You bet. How many data points did we need relative to airline security prior to 911 alone? I recall all the hijacks over the last 30 yrs and even PSA flt. 51. The ability to get guns and other forms of hardware onto the plane, not to mention the ability to get into ****pit was absurd. It was always my pet peeve. How about letting every Tom, Dick and Harry into the US as well…..

I have installed 10 Nuvico WDR NVCCHV266NAI fixed mini dome vandal resistant domes. I would highly recommend them for high contrast lighting conditions within the scene. Also check out Krcctv.com, who have a vandal dome model K-RVDN555 with awsome specs and performance. I have been evaluating and it's built like a tiger tank and more importantly the performance is outstanding.

Arecont Vision 3 megapixel cameras
normicgander replied to GrahamM's topic in IP/Megapixel Cameras and Software Solutions
Rory- Yes. I purchased the LUXRIOT120/4/600GB DVRserver. Came with a PV-149P Pro Video capture card and four channel Luxriot software license. My goal is to a have a Hybrid DVR solution to take advantage of the MP IP cameras. I was going to ask you how that GV card performed with the Luxriot software. Did it produce a good, non-distorted image when there was motion in the captured scene? Thanks -
Arecont Vision 3 megapixel cameras
normicgander replied to GrahamM's topic in IP/Megapixel Cameras and Software Solutions
GrahmanM- Luxriot is taking the DVRserver back for eval and replacement. I really like the software, although I could recommend a few changes it would be minor. The motion detection is excellent and the ability to search and playback archived footage is very easy and effective. Export to AVI and snapshots is an advantage as well. I'm glad your system is working to your expectations... What CPU power are you running? -
Arecont Vision 3 megapixel cameras
normicgander replied to GrahamM's topic in IP/Megapixel Cameras and Software Solutions
I think these cameras have a place, especially if you can rx and record 2-3 FPS second on motion events. Live viewing even at a reduced image quality and say 10-15 FPS would be fine. On my earlier post I thought my Luxriot DVR stablized after cutting the res from the AV3130 to "half" in the luxriot software. But, while not as unstable, I still get disconnects and errors. I realize this thread is for AV 3 MP cameras, but these companies are supposed to be allies under the new IP world of "open Architecture" platforms yada yada.. The Luxriot software even has a menu option "search for Arecont Vision cameras." AV tech support is in Europe and I think the Luxriot salesman is sick of my calling..... I guess my system is "experimental"- not ready for prime time deployment or customer demos... I glad I have good old fashion STABLE analog cameras and low tech DVRs to keep my customers happy.. Was I venting? A little..... -
I think Danweber is entitled to his option on the ICRealtime. It sounds like he has good technical credentials as an engineer and an end-users feedback is equally important. Any dvr company or OEM would welcome feedback of this nature and ICrealtime would agree. I also think in the highest quality setting the compressed 720 x 480 image should be as close to the live view as well. But in reality, we have all seen various DVR recordings in the "720 x 480" mode and thery're not all equal. This is simply because the industry lacks a testing standard or the dvr oems should state the resolution in horizontal TVL. How often due dvr oems tell us how the units A to D is performed? Many of them use ITUs 601 recommendation (as well as ITU H.264) which yields about 455TVL. Vlado Damjanovski's book has a great discussion about this.....

Arecont Vision 3 megapixel cameras
normicgander replied to GrahamM's topic in IP/Megapixel Cameras and Software Solutions
The Luxriot DVR server has a 3.2Ghz Pentium 4. I cut the AV 3130 resoultion to "half" and the system stablized. FYI: AV recommends a 3.2 dual-core processor. Overall great images in the 900 x 600 mode @ 18 FPS... I think the mega pixel cams are nice, but I think I will stick with 1.3mp cameras. -
Arecont Vision 3 megapixel cameras
normicgander replied to GrahamM's topic in IP/Megapixel Cameras and Software Solutions
I just rxd my starter/demo kit from AV, model 3130 D/N with 2/3' Computar 12mm lenses. Very good image quality, but still testing. I'm using a "Luxriot" DVR server. Has soon as I added the Arecont camera error and XXXX started happening. It seem the stream fropm the Arecont hangs or pauses about very 3-5 seconds, which causes an "error" or the picture to the logo screen. Using the AV software I think I can see this pausing in the stream, so I'm not sure if it's Luxriot or the AV cam. FYI- The luxriot DVR sever has a cheesy 4 ch capature card which doesn't capture a 720 x 480 camera. On motion, which happens in the real world, creates a serrated type distortion on the object in motion. It was touted as the advanced unit. The card is a Pro video PV149p and dosen't seem to have the DSP power needed... -
IP Software?
normicgander replied to AdamTranter's topic in IP/Megapixel Cameras and Software Solutions
Just tested my first DVR server with Luxriot. Rory is right software and the motion dection features are awesome. -
Is anyone running into situations where the combined use of analog cameras/DVR with one or two IP cameras is a requirement. Perhaps the use a megapixel camera or the fact that a wireless IP bridge between two building is necessary, making IP cameras more practical at the remote building/site(s)? The montoring software for DVR would also manage/view the IP cameras. Thanks
-
Rory- I take it your talking about the LV footage on TV. It was a pretty bad recording. It almost looked like a recording on a VHS time-lapse security VCR in alarm mode.... They think they will catch them however.

After this I think I will have a statement clause about wide-angle cameras for outside areas or larger inside interiors. It seems most of my customers want the wide angle views to observe and capture general area traffic. Often the images are ok to provide "face recogntion" of known people, such as coworkers etc. I also think it's a trade-off of capturing activity of an overall event and the ability to ID someone or license plate. Example: We all just saw the gang of hoodlums who attacked the man in the MGM parking lot in LV. Had a teleophoto lens been used, perhaps less incriminating evidence would have been captured. In this case the wide-angle was perhaps better (??) Food for thought: Are the DVRs we use really produce "D1" or "4CIF" resolution? How do we know? What industry standard test was the spec guaranteed too? A 720 x 480 uncompression image frame is about 1.1mb. We record the "D1" image frame at a 40Kb to 80kb file size on our DVRs. I realize compression is a must, but with high compression ratios there's no free lunch. D1?

KrCCTV- thanks for your response. It seems I'm running into more of these situations as you discribed. We have a harbor authority here who wants coverage around the marina. Hardwired cabling is not an option. So an IP based solution is key...
-
Wow, maybe this is a wake call. Perhaps our customer expectations are too high sometimes. I think spelling out that the cameras (system) are adjusted to customers field of view requirements and that forensic video results can be effected by such factors as field of view, FPS recording, recording quality, target movement with the scene (image blur) and scene illumination to name a few. People who watch CSI also contributes to the expectation problem...

Hello Members: I'm looking for a recommendation for a rack mount server with Windows XP OS. I would like to have 500Gb of storage for video. Will be using LuxRiot software. I'm configuring this as a demo unit for customer sites and trade shows. Thanks..
-
Nuvico had a new 4 ch video server which featured a USB harddrive port, making the unit an NVR..
-
Rory, I think the one your referencing is the IPIX version. AV- Yes it's the Capture sold by Richardson. The judges are a panel of CCTV/IP industry elites . Again, I posted some products I thought were more practical. Overall a great show. Many of the vendors had some pretty rough-looking video displays (mostly LCDs), which surprised me. I would select high quality or superfine mode and say "thats better." Oh well...
-
Hey Monster, Your right- the 360' camera was neat, but I didn't think it was the best new product. They say it's good for observation, no moving parts.
-
Hey Jisaacmagee, so what DVR have you been using? Just kiddin
-
You all make some great points as usual . Thomas- Sorry I missed you. The folks at your booth said you had already left. Maybe next time. I very much enjoyed the show. I really needed Tuesday for the exhibits. I plain ran out of time. Other comments: The intersting thing for me was looking and using the remote viewing software. Overall, the GUIs seem to be improving industry wide. Crest Electronics have some nice DVRs and an easy to use GUI. Telexper had an intersting GUI layout for their XP embedded DVR. It had maps you could pull up of multi-sites etc. The Mobotix mega pixel IP cameras were very impressive. But I called them and told me you need to sell $50K of product per year . I wish they had told me at the show instead of allowing me to jrool over their products. Oh well, they seem like great IP cameras for the high-volume dealers. The VP of engineering for LuxRiot gave me a demo of their OEM software developed for Sanyo. Very cool- he displayed cameras from a Cheetah DVr and IP cameras from IQeye and a few others. Sanyo will be calling it their NVR software system to be released soon. Many companies use low-grade LCDs which rendered awful pictures. Also, surprisingly many companies had their systems recording and steaming in lower pictures quality modes. Rory- only a few WDR mini dome cameras. I was expecting many more... Got to meet CCTVqueen and G-men Nice folks! My wife won an I Pod. Cheers

Well, I wish those members attending the show a safe trip. Maybe we'll bump into eachother... Rory, Hope you feel better. Any specific product for which you need infomation/eval? Kandcorp are you going?
