CCTV outdoor cameras?

Question

CCTV outdoor cameras?

Answer 1

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders, provides recording for possibly many years, with a variety of quality and performance options and extra features. More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

Answer 2

The presence of CCTV camera system for surveillance will reduce petty thefts and vandalism in shops, malls and other public places. Since the activities are being monitored, fewer nuisances are likely to be created. It also reduces the losses due to shoplifting.The images and videos captured by a CCTV camera system are often recorded and stored into a database. These are helpful in maintaining records so that they can be easily retrieved later, when needed.

Answer 3

Camera selection basically depends upon the exact requirement. Below are few question arise when we choose a camera.



1) Do we need night vision or only day camera is required.

2) Do we need to place it outside the house or inside the house? Outside means it will be open for dust, humidity and water.

3) How far is the object that we need to be covered mainly?

4) What clarity of video capturing you are expecting from the camera.

5) Do we need recording as well or just need live viewing of cameras.

6) How many days recording we need to keep as evidence.

Following are the best possible answers/ explanation of the questions.

1) If we need Night vision camera then it should have IR (Infra Red) LED’s. Higher the numbers of LED high is the clarity of night vision image. Now day’s array cameras are also popular with only one big LED which is sufficient for high night vision viewing.

2) If it need to place outside then it should be bullet camera otherwise in door cameras can be Dome camera.

3) Camera lens depends on object distance. High the distance bigger the lens like 3.6 MM, 6 MM 8 MM or 12 MM.

4) Camera clarity is calculated in TVL’s high the TVL value higher the clarity. Like 480 TVL or 540 TVL is middle level camera and 700, 800 & 1000 TVL are high range camera.

5) If we need recording then we need to place a device called DVR (Digital Video Recorder). DVR contains Harddisk for recording the video stream.

6) High the days you need to keep recording high should be the HDD capacity in DVR app. 1 camera store 1 GB per hour video stream.

Answer 4

Personally, i would get some shrink wrap tubing - basicllay it is like a plastic tube that you put around the connector, then you heat it with a hair dryer or something, and the tube shrinks down to create a tight fit around the connector:



Here is a link so you can see how it works:

Answer 5

Hello



I also gave you some links, I recommend using Ascendent Technology Group for the equipment they have great products and good technical support. http://www.ascendentgroup.com/



A good cameras will allow you to put the wiring through the mount, you can also use Baluns and CAT 5 cabling, and I would suggest 18 gauge for the power. make sure you use 24V AC for outdoor cameras to reduce the power loss if it a run of mroe then 75 feet.



Baluns: http://ascendentdvr.com/baluns/43_1.html

CCTV video baluns, also known as UTP baluns, allow traditional coax cable to be replaced by category 5 and other forms of twisted pair wire in CCTV video camera & surveillance installations. Video baluns allow installers to use more cost effective structured cabling techniques to wire security cameras. By using video baluns, UTP wire such as cat-5 can be run over longer distances easier than coax cable and for less money. Active balun transceivers enable UTP wires for cameras to be run distances up to 3,000 feet.



CCTV Equipment:



Always buy DVR and security equipment from a good brand name manufacturer like Pleco, Bosch, Honeywell and Ascendent: http://www.ascendentgroup.com



Unfortunately many people buy very low end systems which have poor frame rate and bad image quality because they buy from Amazon, "spy stores" Lorex, Q-see, NCIX, new-egg, and other online retailers who sell cheap products for china there were never intended to be anything more then a nany cam and should never be used to provide security.



Not all DVRs are created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of DVRs you can find the equivalent of a $10,000 Kia and a $350,000 Ferrari and everything in between. Both have 4 wheels and windshield but that where the similarities end, it’s under the hood that counts. Just like any other consumer electronic in the end you get what you pay for.



The smaller the files size the more images 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 recording storage time, how much you can back up at once, how fast it renders and searches video. The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most important spec of any DVR.



If you are buying a DVR and streaming is a high priority I suggest you ask for a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVRs say they have remote viewing but it is often too slow and laggy to be of any use especially if it is a standalone.



Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means it’s not a good product and will probably have a working life of about 2 months. Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.



DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.



Also as far as night vision or IR cameras go most do not give good images in the dark. Many companies claim good night vision but there are only a handful of brands who give night vision over 30 feet out doors. normally if a cameras is rated 150 feet of IR it will give you ok images at 30 feet at night and good images at about 20 if rated for 60 feet you might get 15 indoors and will be useless outdoors.

Economical DVR's

Two good economical DVRs I would recommend are Ascendent's AVP-4120 DVR or Pelco's DX-400. The AVP-4120 uses the latest H.264 codec to improve streaming and recording time, and will allow PCs and smart phones to remotely view and control your cameras. These are the DVRs I would recommend that are good quality and affordable from companies who stand behind there products.



Again if you are going to buy no name products save money and get dummy cameras they are just as affective and you will be less disappointed.



Hope this Helps,
