How do you feel about security cameras inside an office?




bleuflamen


I used to work for an IT shop that started selling and installing security cameras inside offices to record employees at their desks, in hallways, etc. What I saw is that the morale plummeted at all the offices we did installations at.

Ironically, at one of the companies, I knew the manager watched porn on his computer because I saw temp files from it when I worked on his computer. And he was one of only a couple people without cameras in their offices. I didn't report this to anyone, as he was essentially my boss while I worked there.

Have you ever worked in an office like this? What are your feelings on the subject.



Answer
I work as a security officer at a highly secure data hosting centre.
We have cameras literally everywhere, with exception of the office.

They wanted to install there as well, for obvious security reasons, as office space is a common place for burglars, who runs off with monitors, projectors etc. but the staff said no.

I, personally, don't like being spied on like that. If you have to spy on your own staff like that, you have a trust issue, and trust, among other things, is what keeps most companies running.

I disapprove of security cameras inside offices. Elevators and hallways leading to ie. restricted access areas can be okay.

I'm looking for a good office camera security system. Any recommendations?

I would prefer the cameras to be wireless and to have a DVR. It would be nice if there was an app I could access the system from my phone. I would probably need at least 12 cameras.


Answer
I like Swann and Lorex systems for these (or smaller) systems.

There may be valu in getting two systems so if one fails, all the cameras are not down - but that is up to you.

Since we do not know the office layout, we do not know how the "wireless" part will work going through walls made of various materials.

Quick review:

Wired security cameras have a single "bundled" cable that contains the video feed and power. There are two plugs at the camera - one for power and one for video. At the DVR there is a connection for the video and the power plug connects to a power source - usually a "wall wart" or some sort. You can locate a battery back-up system at the DVR to power the DVR and the camera in the event of a power outage.

Wireless security cameras send only the video wirelessly. The camera still needs power (wire #1). If battery backup is needed, then some sort of local UPS is needed. The video is transmitted wirelessly to its base station mate. The base station needs power (wire #2). The base station connects with wire (#3) to the DVR.

You will also want to invest in a couple of monitors that connect to the DVR. 16 channels is a lot to watch. For the monitor at the DVR, a low priced, VGA-connected computer monitor is fine. There may be a need to have auxilliary monitors around the rest of the property. Use of the composite video out makes that easy.

Connecting the DVR to the computer network is easy enough - be sure the network is segmented using a network switch (not just a hub) so the video traffic and be isolated from the rest of the network. Use of PnP is easy, but a network admin with half a clue will know how to set the IP address and security properly. Also, for the remote access you want, setting up the router to allow your access while maintaining network security is needed. Again, any half skilled network admin who understands IP networks and router configuration can do this. This works best if your internet provider gives you a static IP address, but can still work if a dynamic address is used - there are some work-arounds and compromises you'll make is you go this route.

I would suggest sizing the system with more ports for cameras than you think you need - in case you decide to add cameras. In this case, two 8-channel systems gives you decent coverage. And a composite security camera will work on any manufacturer's system. I have installed Swann DVRs with Swann, Lorex and other manufacturer's analog, composite video, security cameras...

You did not tell us if the cameras will all be indoors or if there will be any out door (parking lot, alley, etc) in which case you may want outdoor-rated night-vision cameras in addition to the indoor versions.

About security cameras?

Q. So, I've been wondering for a while about punishments of crimes and these security cameras and laws and ect, because I'm always curious. I'm JUST wondering, I'm not gonna use this to do anything wrong or something. Is there someone watching security cameras 24/7? Or do they only look back at them in a crime. For like banks and crowded malls, I would expect someone watching all the time. But like in small stores and schools, is someone really watching our every movement?! I can't imagine someone having the BORING job of watching a camera everyday, just wishing for some action.


Answer
Like you said it depends on the location. Some places have people constantly watching them, others record them and if they find out there was a crime they will review them. A lot of places (like schools) will have someone watching the monitors but they will have other jobs as well. So in a school, often times the monitors will be in the deans office or in a school police office, and the person will have other duties that they do, but they will try to keep watch of the cameras as well.

Banks definitely have people watching them all the time and stores usually do to.

Inexpensive security camera?




Wundt


I work from home and my office is at the back of the house. It would be nice to had a CC camera to show me the view out the front door (so I know if someone is at the front door or to see if my son's bus has shown up). Similarly, all of our bedrooms are upstairs and you cannot see the front door and we would like to know who is at the door before we run downstairs to answer.

Is there an inexpensive solution for this sort of setup? It looks like most sets I have seen run several hundred dollars, it seems to me that I should be able to set up something using inexpensive off the shelf pieces.



Answer
radio shack came with monitor/4 black and white camers/75ft. of audio/video for each camera/bought mine over a year ago no problems. paid under $100.00. Camers are no bigger than your thumb. Monitor has outs for recording. good luck and be safe

how much mbps is required to watch my security cameras from home?

best security camera for office on Cheap Security Camera - Best Fake Dummy Security Camera Motion ...
best security camera for office image



Mike


I need internet at my business for my security cameras so i can watch the live stream while away from my office. What internet service would be the best choice for my situation, and how much MBPS is required?


Answer
There are many factors to consider like what type of camera do you have an analog or IP?

An analog camera with a viewing resolution of 528x320 will require 0.56Mbps of bandwidth.
An IP camera with a viewing resolution of 640x480 will require 5.28Mpbs of bandwidth.

The other thing to consider is that if you are going to watch the video while away from the office then you will need Wi-Fi internet access at your home or any where else in order to see the video feed from your office. Just having internet at your office doesn't mean you will be able to see the video away from the office.

I hope this helps.

Can I use a junction box above a drop-down ceiling for an outlet?




Nick


I am trying to install a couple of security cameras at my office. The cameras are wireless and will connect to my domain so all I need is power to plug them in. I have a drop-down ceiling with four bulb florescent fixtures. When I look above the drop-down ceil there is a junction box for each fixture.

What I am wondering is if I can use these junction boxes to put an outlet on the faceplate, or something along those lines so that I can plug in the cameras. Of course, I want to use a qualified electrician to do this but am trying to find out if it is even possible before I waste his time and/or the service call.

Thanks!



Answer
It is more than likely that those lights are powered from a 277/480 volt panel, and may only have power when the lights are turned on. You could check in your electrical rooms to see if you can find any transformers, if you got em, you got 277v lights.

There may still be boxes that have 120/208 volt in them, please be aware the electrician may need to shut down multiple circuits at a time to tap into the neutral without risking damage to your equipment.

You may have code issues if your ceiling is a "return air plenum", no equipment or cord that can cause poisonous smoke will be allowed, you can identify if your ceiling is a return air plenum by grates in the ceiling that are not connected to ductwork.

Does the security cameras at my job have audio?

best security camera for office on security camera
best security camera for office image
Q. It seems like my boss knows everything that goes on outside of his office and his door is closed. Is it possible that he can hear the conversations through the security cameras in the ceiling?


Answer
It's possible. But having a security camera running 24/7 with video and audio takes mass amounts of storage since the data isn't compressed.

It's more likely someone tells your boss what is going down.

I need a security camera to keep an eye on the office by the pool?




mike f


It is a condo office and someone has been smearing butter and throwing eggs at the mail boxex and office front door. Needing a security camera with out flash and wont be noticeable to the suspect the office is about 200 feet from my condo unit. I am also security for the condo, this happens at diffrent times of the day and night


Answer
You need to fit a low light camera fairly close to the office. Then a cable to your location, or into the office where it can be recorded by a security video recorder, a computer with a cctv card or a dedicated cctv camera server. Unless you are experienced in this you can waste a LOT of money for no results.

How many bits does each pixel take?

best security camera for office on sharonmadds: Wait, They Have Surveillance Cameras Watching Us Cashiers ...
best security camera for office image



kris l


A security camera in an office building has 1000 x 1000 pixels. Each pixel shows a grayscale intensity of 1024 levels. The camera takes one image per second. The building has 15 identical cameras with the same specification as described above.


Answer
The key info here is "Each pixel shows a grayscale intensity of 1024 levels."

lg(1024) = 10 bits

edit: Sorry Silhouette... here's how it works... Each pixel takes 10 bits therefore
1000 x 1000 x 10 = 10 million bits / 8bits/byte = 1,250,000 bytes
1,250,000 bytes / 1024^2 = about 1.19 MB per picture uncompressed

Is it illegal to record audio in the office using security cameras (with built-in microphones)?




J U


I am in California and I am in charge of putting up security cameras in the office.


Answer
As long as the employee manual states that all communications and actions in the offices are SUBJECT to recording, that proves as warning enough.

Employers absolutely have the "right" to make sure their employees are working, not stealing corporate assets/services and to protect them company from an employees actions concerning outside forces.

Answer
If this were âreal worldâ then more information would be needed. How efficiently is the data encoded? Is the data compressed? Are any parity bits used?

Assuming that the encoding is 100% efficient (no waisted bits, no parity) and there is no compression:
Each pixel would take 10 bits for 1024 greyscale.
Each picture would have 1000x1000 = 1,000,000 pixels.
With 15 cameras each taking 1 picture per second, there is 15 pictures per second.

That is 15 x 1,000,000 x 10 = 150,000,000 bits of information per second
Which is 18,750,000 bytes of information per second in a perfect world. (8 bits per byte)
If you want true megabytes, then divide this by 1,048,576 bytes per megabyte.

In the real world, parity would likely be used, and compression would also likely be used. So the data rate could actually be lower.

What car security camera would this be?
