I'm no expert but your not going to 'cover' a area that large with only one camera. As mentioned often on this forum: a PTZ can only see in one direction at a time. Which means the camera will be facing the wrong way -most of the time- If you want them to have a camera which gives the best overview so they can browse around, yeah, put it up right in the middle

About MP cameras and low light; are there any MP cameras that have the same low light capabilities as the CNB?

Any updates on the testing? Thanks

That's a nice video. Does anybody know how the Dahua ESIP-MP2-DM1 performs in low-light compared to the CNB VCM-24VF?

Hi, I have a strange issue with the EagleEyes app for the iPhone and iPad. Let me explain the setup: The local network contains 2 Apple Airport Extreme routers. One on the ground floor (#1) and one on the second floor (#2). These routers are linked (via ethernet cable) to create one (WIFI) network. There is a AVtech AVN244 PTZ IP camera located on the second floor (outside) which is connected via a ethernet cable to router #2. Then there is a AVtech AVC796 8 CH DVR (with currently 2 CNB VBM-24VF cameras) which is located on the ground floor and is connected to router #1. When viewing the IP cam and the DVR on a computer (connected to router #2 via ethernet) with the AVtech video viewer or via the web interface everything works great, FPS is around 25-30. And the feeds are realtime. But here comes the EagleEyes part. When using the app on a iPhone (4) connected to the local WIFI the following problems occur: The AVN244 feed starts to lag behind when using the PTZ functions. The feed is realtime untill the first PTZ command. From that point on it starts to lag behind more, second by second untill it's far from realtime.. This also happens when I turn the iphone to landscape mode (without even using PTZ or anything). The DVR feed on the iPhone is never realtime. It's always lagging behind more and more (5-30 seconds) and the framerate is about 5-6 fps when viewing a single channel. The weird thing is: the PTZ camera feed does not lag behind when using the EagleEyes app on the iPad (1)! Unfortunately the DVR feed has the same issues as when viewing via the iPhone. To sum up: iPhone: using PTZ or landscape-mode = lagging feed for IP cam. DVR feed is always lagging behind and low FPS. iPad: PTZ IP cam works fine. DVR feed is always lagging behind and low FPS. Because of the 'landscape mode' issue I think the problem is inside the EagleEyes application and not so much the local network or dvr/ipcam. Also because when the iPhone is lagging behind and I give a PTZ command I can see the camera moving on the PC feed instantly. So the commands are executed realtime, it's just the feed that's displayed with a delay on the iPhone. I've made a video showing the issue using a iPad and a iPhone: http://www.ljagtproducties.nl/AVN244-lag-iphone.mp4 I've contacted AVtech several times but the only (laughable) reply I got was "it could be your mobile 3G network or your internet connection".... As you read above, it has nothing to do with internet since everything is done local.. Is there anyone with the same issues? Or maybe someone with some tips? Thanks in advance! PS. if there is no solution I'll just dropkick every bit of AVtech hardware out on the street

Is anybody using the avtech eagleeyes app with a dvr or a ip camera? If so, how's the performance and what kind of setup are you using? Thanks!

Thanks for your reply Tom! Tech support stated it could be my 'internet connection'. But I'm not using it over the internet But I did try the setup with other routers. I've connected the DVR directly to a Linksys router: the same problems occured. I've also tried it with a Sitecom router but no luck. The routers where set up to test the issues so they were not connected to anything else. Just the wifi enabled router with the DVR connected via a ethernet cable. But how can it be my network? Look at the iPhone issue when using the AVN244 IP cam: the feed is realtime untill I rotate my iPhone into landscape mode. From that point on the feed starts lagging... That can't be network related right? Also because this doesn't happen on the iPad.

I guess nobody has this issue or nobody is using AVtech hardware / the EagleEyes software Maybe someone knows about any other iOS apps that (could) work with the AVN244 and the AVtech DVR? Thanks!

Hi, What is the best way to find cables (cat5 & coax) that are already buried in the ground? I'm at the beginning of installing a camera system in my garden and as it turns out there are already cables in place, but never used. The cables have 5m extra length for mounting on a mast. Only problem is nobody seems to know where there are exactly. I do know in what 'corners' they are, but after digging a few holes here and there I still can't find them. It's like looking for treasure, I got this large red X that marks the spot and that's all I don't even know how deep to dig.. Any advice? Thanks in advance! All the best, LJ

No tips or tricks? I've been digging around and found 1 cable set out of 5. I guess I'll keep digging

Good to know, thanks!

Hi, I'm trying to figure out the best way to setup cameras (and the needed wires) for home surveillance. This is a map of my house + surrounding area: (Red lines indicate the points of interest e.g. windows & entrances.) The house is surrounded by a hedge which is about 2.20m in height. The yard is as good as obstacle free (there are some small trees but nothing that can block the view of a camera). The house itself is about 9m in height. It's not possible to put cables under the parking area (it's sunken in cement, so I can't reach the ground underneath it). At the rear of the house (the 16.80m wall) there is a solid stone floor (patio), so it's not possible to let cables enter the house via that wall because they would have to go over the stone floor and be visible. Cameras: I'm going for CNB VBM-24VF cameras (with a wallmount) connected to a AVTech AVC796(B) 8 channel DVR. I don't know exactly how many cameras I'll need at this point. On the front of the house (bottom left corner of the picture) I'm planning to mount a AVTech AVN244 IP PTZ Speed dome on the second floor (to monitor the street). The AVN244 is only for 'looking around' not for recording. So the front of the house still needs to be covered by a camera connected to the DVR. Lights: There is a decent amount of light coming from the street, but on the rear of the house I think I need some additional lights. This can me IR or floodlights (no neighbors on that side). I have to test the VBM-24VFs to see how the perform with the current light. Cables: I've read about a lot of options to wire the cameras but I'm kinda lost. I do like the idea of 1 cable per camera (combining power + video). I guess the needed cable depends on the distance of the specific camera? I'm not sure if I want to place the DVR in the house or in the garage. But the DVR needs to be connected to the internet and there is currently no internet connection in the garage. Some other info: - The setup is not for identification, but just to see 'whats going on'. - I'd like to stay away from drilling holes (yes, that's right ) - I'm not a big fan of camera posts/masts - I have no experience in any of this so any help or advice is much appreciated - I already own the AVC796 and AVN244 so that's what I'll have to work with I'd like to see how you guys think about this project. Thanks in advance for any tips, info & help! All the best, LJ

Just got my first CNB VCM-24F in the mail. I noticed this line in the manual: "Don't use UTP to power via 12V DC power source". Why is that?

A traffic-sign post: 3.1 meter above the ground. Including delivery 70 Euro. That should work

Hi, I'm planning my surveillance setup for around my house (topic: http://www.cctvforum.com/viewtopic.php?f=53&t=26861). To get a better view from the camera's I'm searching for 2 or 3 camera poles (max. 3 meter above ground). The ones I can find are starting around 600 Euro: Which is too much for me. I need something much more simple. For example just a pole in the ground and that's it. Has anyone ever build a camera pole? Is it possible to just hammer a pipe into the ground, or create some sort of pipe construction? Something like this: Or is that bound to go wrong? Thanks!

Ah, good thinking! Yes, I do want to use motion detection. I think I'll just dig a hole, put the pole in it, and fill the hole up with cement. And see what happens Cable wise it just needs to hold a cat5 cable. So I'll have to create a opening under ground.

Thanks for the information! And what manufacturers should I look at? There are some 'neutural' branded lights (solar and normal) available from a hardware store nearby, should I just try those?

Ok, one BNC camera + a balun set on the way for testing. Next up: floodlights. I'm thinking about solar powered floodlights (to avoid more cables). Has anyone any experience on those kind of lights?

You mean soldering the camera power wires to the cat5 power wires? That sounds like the easiest option.. And I saves me buying screw connectors

I'll stay away from wireless How would I connect the power to the cat5 cable? (from the power adapter to the cable, and from the cable to the camera) EDIT: Ah, like this:

Ok, let's talk a bit about the cables. I like to use 1 cable combined for video and power. And of course I like to keep the best quality. In the worst case scenario the longest cable will be around 80 meters (260 ft). What I'm thinking about: or Another possible option (for the most distant camera): wireless.. Small note: some cameras in my layout have a power source near them so this product (or something like it) could be used for the video feed: Has anyone had any good experience with a wireless connection?

Maybe this can help: http://www.cctvforum.com/viewtopic.php?f=3&t=20973

The garage is about 55 ft from camera #2. I do think you are right though, I will need some lighting. But I'll have to see what cameras need lighting once they are up (#2 and #4 are probably the ones, yes). It's not like we have things of great value. Besides, the 'things' that do happen around here are all done by the same black clothed, cap wearing dude. In other words there is no way you can see their faces When we are not at home, they can try their luck, the house is rigged with a fine alarm system. The camera system is more for when we are at home, so we can check the property with one look on the iPad or iPhone. And if something is detected, say at night, I can respond to it.

I was under the impression that the CNB VBM-24VF works very well in low light? http://www.cctvforum.com/viewtopic.php?f=5&t=26832 The front of the house and the parking get some light from the street (I think it's enough for the 24VF). At the back of the house I will need lighting (although it's never completely dark), but I think some IR or a wide spreading floodlight will do the trick. I have to try this when the cameras are in place.

Correct, ok, I'll try that 'garage based' layout in the CCTV Design Tool!
