I wouldn't have thought so, generally, it just means stuff doesn't work as it should. Like a torch with a flat battery, the light isn't as bright. Damage to cameras usually comes when you try to power a 12VDC camera with 24VAC or something silly like that because then you start blowing stuff up.

# of cameras and limit writing to 1 hard drive continuously?
Campbell replied to mike_va's topic in IP/Megapixel Cameras and Software Solutions
I've tested these with high hopes, and they stutter/gap footage. Replaced 'em all with Western Digital Blacks, no stutter/gapping. I'm just going to put it out there that I've "NEVER" had any issues with Green drives. No read or write issues period. Of course, I pretty much exclusively use megapixel IP cams, but I wouldn't think that would make a noticeable difference. And this is from anything from a singular 2TB drive to a 20TB array (which has been going almost 2 years without issues). -
Running the speedtest may not be helpful. All that does is checks your upload and download speeds on the internet. Dependent on where everything is located on the network, this might not tell you anything at all. A network diagram is more helpful and would allow us to identify whether it is a network problem (which Im betting it is)

15 megapixel cameras. Check your bandwidth. I don't know how your premise is wired but definitely check on your bandwidth. Could be you have a choke point somewhere or your network is simply flooded. Actually, I'd almost bet the house on this being the issue (almost, so no you can't have my house if I'm wrong ) It's unlikely to be your PoE switch, but make sure that's not maxed out.

Need advise on security of network CCTV
Campbell replied to iantao99's topic in Computers/Networking
These are different cable types. Typically, an analog camera will require a coaxial cable to stream the video from the camera. That's fat cable that if you cut it open has a copper core, surrounded by a thick plastic sheath which is covered in copper sheath then the insulation on the outside. A digital camera uses Cat5/5e/6 which is cable with 4 twisted pairs of copper cable inside. This is the type of cable you use to plug your computer into a network. You are able to run the video over Cat 5 cable via a little converter known as a balun. Most people do this these days as most premises are extensively networked with Cat 5 and not coax. Hope this clears things up for you mate. -
What options do I have with Windows 7 and CCTV cameras?

Is this what you were looking for? -
Problem with door releasing when door is wiggled.
Campbell replied to jmorin78's topic in General Access Control Discussion
What system is it? -
-
Why System 3? System 7 was introduced over 4 years ago and System 5 tech support was made chargeable at the beginning of the year.

Why make them press a button when you can just let them swipe to open the door and record it that way? SEems to me as if you're adding an extra unnecessary step. With that in mind, any access control system worth its salt should do that.

Hang on! You can change the lens to suit the environment with an IP camera, just as you can with an analog. You can't know what his lighting is like in his building but most I know are easily light enough to accomodate CCD chips. And at 30ft? or even 90ft... that's only 30m. 1 camera at each end with IP is easily going to be enough to cover 10-15m even at 1.3MP. Your scenario of boys climbing windows to get into a girls apartment whilst not unique is surely not common. I've never had it happen on any of my jobs. I guess it comes down to preference. I pretty much exclusively use IP cameras these days, rarely does a situation call for something other than unless it needs to be basement price. I have no issues with lighting or anything else. -

You don't need facial recognition the entire length of the hall... It's a hall. It has 2 walls and 1 exit at each end... They aren't going to be Shadowcat from Xmen and walk through the walls. They'll pass it on the way in and on the way out. -
The heat factor also has to do with your cooling as well. I use AMDs a lot and have never had any heat issues or otherwise.

Interference on a short-run (<8 meters).
Campbell replied to mastertheknife's topic in Installation Help and Accessories
Its pretty strong and long-lasting actually. Although at first i only considered it a temporarily solution, the other camera is mounted like that for about 1-2 years now without any removal or re-tightening. The cable is a ~12-14 gauge solid core and is hard to bend. mastertheknife Oh I have no doubt it serves its purpose and does it well. But from an professional installing point of view... -
2.8. Although you should test it first to see what is most suitable for your environment. You may find that your 5 has enough width to cover what you need in greater detail.

I pack my whale. You never know what you'll end up needing on a site. So... in the belly of the whale. Conduit accessories box - Jboxes, elbows, t-pieces and corrugated conduit and saddles Heavy duty tool box - The torch, rotary hammer drill, hacksaw, mallet, other odds and ends Fasteners box - Anything required to fasten something to a wall. UTP box - Anything UTP cable related Coax box - Anything coax related Drill bag - 11 batteries, impact driver, normal hammer, 2ndary torch, various drill bits Generic toolbag - Containing generic tools UTP cable - Always carry spare. Ladders and conduit of course, but they go on the roof racks. **edit** Forgot one. Generic tools has screwdrivers, side cutters, pliers, hex keys, allen keys, markers etc. I also have the other tool box with hammers, chisels (needed one once) multigrips, and some other odds and ends. -

Campbell replied to SectorSecurity's topic in IP/Megapixel Cameras and Software Solutions
Data is still data and as a result still has the same limitations. You'll need to toss in a switch somewhere to run that length. Bear in mind if you're using PoE, the power wont run through the switch either -

I'm not so finnicky about giving help however, Numbnuts is right about the lack of detail. Without a survey of the site, it's hard to give specifics. It should be left to a pro. You could be installing them in the wrong places, with bad FOV's wrong cameras in the wrong places. On very basic information and on the basis that I love Vivoteks for quality images with a really good price. 4 x MD7560s at each end if this is what you want to do 1 x IP7361 outside to cover the door. However, bear in mind with IP cameras, that your max run is about 300ft/100m of cable between switches and that PoE won't travel through a switch. No idea what else you need... as I haven't seen the site. Thats on very basic information with my favourite cameras. -
Love that site You only need 2 pair for cameras. 1 for video, 1 for power. the other 2 pair can be left free. It's all just copper after all.
