A black orb of light was caught in my security camera?

Q. So I live in an apartment building that may or may not have been here since around the late 1800's, and many people have died here according to my mom who decides to tell me this all now. And also, someone has died in my apartment. My superintendent usually checks the security cameras from 6AM to around 10PM but he decided to check around 12AM-2. So basically at about 12:58 he saw a black orb in the footage just moving back and forth on the first floor, then proceed to fly up the stairs.. but I'm not sure where it went. I have seen the footage but I have no idea what it could be. I live on the 4th floor but I have never had a paranormal experience. Can someone please tell me what this could be?


Answer
If the security camera was not particularly high resolution or if the object was out of focus (like being too close to the lens) it could have simply been an insect (most telling is that it flew up the stairs).
Some insects are highly reflective (even black ones) so depending on the light source of the camera (or surrounding light sources) it is possible that an insect could reflect back enough light to appear rounded (orb light) due to the shape of the camera lens.
However, I have not seen the footage so I can only speculate based on your description.

Security Camera question!?




Jack Smith


I need a camera of some sort to catch what my dad does to me when we disagree on something.. he gets so angry and sometimes hits me for being wrong etc.... I was thinking of putting some sort of camera on the ceiling or if it was small enough close somewhere anyway if there is such a camera where could I buy it?and write down personal expirecences thanks!


Answer
Please don't give advice when you have clearly never worked with CCTV equipment. Amazon sells complete junk and the video taken by non CCTV cameras often wont hold up in coart because they need water marking in the images.

What you want is a DVR a DVR converts analog cameras and as well as storing images on site allows you to distribute video over LAN and WAN networks. (internet and network) this way you have both on site storage and recording at your house.

Just about any Analog DVR will do what you are looking for and not only display them but record them as well they will also allow you to view them over the internet from a Iphone or laptop.

Many people have a misconception that IP has Superior scalability then Analog but with the advancements with DVR's this simply isn't true, you cn do up to 16,000 cameras each camera could even be from a different DVR and a different site.

And when you are using the internet to connect multiple sites together analog transmits over the internet faster with less latency using less bandwidth allowing you not only to view and monitor a situation real time but also effective control PTZ cameras.

What is the Advantage of IP?
Many of the so called advantages of IP simply don't hold water in the real world, IP is mainly Hype and marketing and outside of a few niche applications such as 1 or 2 camera installs, where MP cameras are needed or large scale wireless projects which represent about 2% of the total CCTV market, IP has very few advantages compared to analog based on performance, cost and reliability. (yet all companies touting IP will often use MP cameras to demonstrate the advantages of IP)

IP video is more about marketing then it is about performance as larger companies like Bosch pelco Honeywell axis can change for both hardware and software and once you use there cameras you have to keep using there cameras unlike analog.

Also IP sounds great, plug and play, Better image quality, use existing infrastructure, who wouldnât want that unfortunately this is often not the case.

IP cameras are based on CMOS
Analog cameras are based on CCD (usually)

A CMOS sensor is constructed using a array of pixels, but unlike CCDâs CMOS do not have a capacitor to store the charge for each pixel.The rows of pixels are activated sequentially rather then individually

This means CMOS has some significant disadvantages compared to CCD, this means CMOS
have inferior ability to cope with ambient lighting such as back light, bright, deep shadows contrasts, low light and IR this is also known as the real word.

In short unless you have perfect lighting a good CCD camera will outperform an equivalent CMOS camera.

File Size:
The smaller the files size the more images that are able to be sent and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities as it also determines the recoding storage time, how much you can back up at once, how fast it renders and searches video.

IP cameras have up to a 5X larger file size then analog cameras. (at same resolution) I have seen MP cameras that on 2MP resolution are over 300X (%3000) larger then our X3 DVR on a CIF image. This is an extreme case but generally speaking IP cameras have a much larger file size.

Most routers and switches are not designed to handle IP cameras they have enough bandwidth but they are not able to process the amounts of commands. (9 IP cameras 30FP is 230 instructions per second) standard routers have enough bandwidth (up to 1GB) but cant handle the amount of tasks (instructions) so frames get dropped latency is introduced and the effectiveness of other devices such as POS, printers and dats storage can be affected and compromised.


Donât get me wrong there are some brutal analog cameras and DVR out there but If you see a good D1 resolution image such as Ascendents Hardware compressed you will not be so quick to join the IP bandwagon.

IP is a young and emerging technology and I have no doubt that in the future it will outperform analog cameras but its not a mature technology yet. Once we start to get standard IP platforms, get rid of license feesâ and existing networks have larger bandwidths then IP video will be a good solution, but until then analog is the way to go.

Make sure you get good cameras as well, Ascendent has the best IR outdoor cameras on the market and are about %50 less then Bosch while offering triple the distance.

Outdoor security camera system?




Casey


We have recently installed a chain link fence behind our home and are planning on letting our great pyreneese out during the day when we are at work so she is not kept in her kennel. We have an awning for shade and shelter, and we will be home around 4:30 or 5:00 each day to check on her. With that being said, we have had issues somewhat in our neighborhood, due to a busy road behind our house. I am not comfortable leaving my dog outside all day or at any time actually without some sort of security system to monitor and video my dog, in case someone was to stop or try to pester etc my dog. I have looked online and have found a ton of outdoor security cameras, however, I have no idea what I am even looking for. I want something that records so that if I come home and somethings amiss, I can check the recording to see what happened that day. I also am needing this to be wireless and obviously weatherproof. All information, models, reviews etc are greatly appreciated.
Rick B......If I find something amiss, the camera will help me to identify the vehicle that had stopped....I never once said my backyard was unsafe...I said we have had issues in the past (such as speeding cars....stolen lawn items) believe me I would not let my dog play outside if the area was a danger zone and I thought she would be harmed or killed, however, as a responsible adult, I would like to have eyes on the area when I cannot be around. I am very proud of you for taking such good care of your pet. I too live in a nice community outside of town, with a covered patio and a wooden fence surrounding my patio, both with gates and a doggy door for my 80 lb dog to retreat too if needed. I also have a locking gate on our chain link fence surrounding the rest of our yard. Once again, I never said that my area was a danger zone, but yes, I live in reality where every great once in a while there is a bratty kid that comes by speeding, or steals my neighbors lawn ornaments. I have d



Answer
Two types of systems:

1) Analog cameras connect to a DVR. The DVR connects to the computer network at your house. The DVR has the feature/functionality for the cameras (i.e., motion detection, send you email when an alarm event is triggered, local video storage for later review, etc.).

2) IP-network based cameras connect to the computer network at the house. The camera becomes a network node. For local video storage, a Network Video Recorder (NVR) is used.

Both methods have pros and cons. What I have found:

1) "Wireless camera" is an inaccurate description. The camera needs power (wire 1). For the first option, the wireless video signal is sent to a base station (or receiver). The receiver plugs into the DVR (video signal) and power (wires 2 and 3). Usually, these cameras are transmitting in the 2.4 Ghz range. This is a shared spectrum and can have interference from lots of sources - including wifi, garage door openers and cordless phones.

2) IP network cameras seem to be more expensive than the analog cameras. The imaging chip seems to be the first thing to go on any security camera, so I use the analog cams (connected to a DVR). The decent consumer cams start at about $150 or so. Less than this and I find myself replacing them at least annually - but at this price point (or higher), they seem to last a bit longer.

3) Because the DVR is on the network and maintains the features for the cameras - including network connectivity for remote viewing and storage, the cameras can be "dumb" = less expensive.

4) Set a budget. I like/use Swann and Lorex gear. It is more expensive than some others, but I have learned (the hard way) that you get what you pay for.

5) We don't know the yard layout. Generally, I would install cameras under the eaves of the house so they have some protection from the elements. We don't know where you are, but extreme heat and cold are not good for electronics. Installing under the eaves helps protect them from the elements (even though they are outdoor rated). If there are environmental extremes in your area, plan to replace the cameras often - or install them in protective housings. This also makes access to power a little easier if you go the wireless route. If you go with wired cameras, then running the single cable between a camera and the DVR may also be easier. That single cable has a couple of plugs on each side - one for power one for video.

You can have a mix of wired and wireless cameras.

6) Set a budget. For just the cameras and DVR, plan on about $1,000. If you can do the installation, great - otherwise, plan on that expense. Again, we don't know the layout... I suggest starting with a 8 or 9-camera DVR, but with 4 cameras. Example:
http://www.amazon.com/DVR8-3200-Channel-Digital-Recorder-SWDVK-832004S-US/dp/B00GBYMUNO
The DVR has a large internet hard drive, 4 cameras get you started and when you want to add more, you have capacity. You do not need to use Swann cameras... but these
http://www.amazon.com/Swann-SWPRO-760CAM-US-Pro-760-Wide-Angle-Camera/dp/B008B4K7O6
I like a lot.

If you choose to use only 4 cameras for your stated purpose, no big deal - add cameras to the front and side of the house if you want... or leave the channels unused.

7) You can provision the DVR to send you email when there is an "alarm". If you set up the motion detection areas, that can be an "alarm". Be careful with this - you can end up spamming yourself with unnecessary email alarm alerts.

8) If you are familiar with how routers work, you can set up remote access through your home's router and get into the DVR remotely (after you get an email alert) using a smartphone with an installed client or a computer (Windows or Macintosh).

9) POWER:
if you are concerned about power outages and losing video then some sort of power back-up will be needed. This is where the wired cameras are easier - with the power and video signal coming to a single place, the DVR and all cameras can be plugged into a "UPS" commonly used for computers. And if the DVR is located near the computer network router, that can be plugged into the UPS, too. If "wireless" cameras are used, then each camera will need its own battery backup power supply.

Security Camera Question?




Patient Pa


I just moved into a new neighborhood and have had some issues with (what I believe to be) one of my neighbors. I have a set schedule every day and my roommates schedule varies (no one is home at all times to watch), but one particular neighbor has been trespassing and verbally harassing my pets.

We've caught him shining lights through our windows (from his property) at night as well as caught him harassing my dog through our front window. I want a camera to record these behaviors so I can go to the cops with confidence that something will be done about it.

I'd like to get a security camera that records to my laptop while I'm at work, and I can review it when I get home. I would like to place it on my second story wall (ample power supply there).

I was looking at this camera: http://www.amazon.com/VideoSecu-Bullet-Outdoor-Security-Infrared/dp/B001IBFSJ8/ref=sr_1_1?ie=UTF8&qid=1312832168&sr=8-1

But I have absolutely no clue what it records to or anything like that. Any camera suggestions would be greatly appreciated!
Also, if there's a camera that can record to a USB device or the like and THEN I can review it on my laptop that would work fine. It needs to record at least 8 hours (while I'm at work.)



Answer
That camera isn't bad, but you probably don't need anything that elaborate. My suggestion would be to get a simple, but good quality, webcam and a USB extension cable. Look for a camera that has decent resolution, and is fairly small thus making it easy to conceal. You can easily record a webcam session for review when you get home.

IMPORTANT NOTE: DO NOT RECORD AUDIO! You'll noticed that whenever you see video surveillance images on the news and other shows that there is never any sound. The reason for this is because unattended recording of audio can be considered to fall under the illegal wiretapping provisions of federal (and in many cases state) law. It's stupid, I know, but there it is. You don't want to end up getting in trouble yourself while trying to protect yourself and your four-legged friends.

Good luck!
