Security in many forms is essential to our daily life. CCTV camera plays a vital role in providing residential and industrial security.
In India usage of CCTV cameras has certainly increased, both for residential use and mostly in industries. It feels quite secure when you have trust in something that is monitoring the surroundings. One to choose their perfect conditions for monitoring, IP cameras comes with significant varieties.
While buying an CCTV camera, few opinions should be considered which would help you to get the item which you require.
Better Screen Resolution
As compared to other cameras like analog, IP cameras provide much higher screen resolution. With IP cameras we can zoom in any picture, and there won’t be any blurry image.
Can be specific
IP camera lets you highlight any footage. Other analog cameras do not have that feature. IP camera saves time because you don’t have to go through all the footage.
Better Network
IP cameras have encryption built right into them providing a more secure network whereas the other cameras like DVR and analog camera network is an issue. Interference is also not a problem with IP-based models.
Two-way communication
You can send commands to the camera, and you will receive the information. For example, you can adjust the focus of the lenses through remote or through your computer or mobile.
No need for new wiring connection
The analog camera requires a different system to be installed each time. IP-based cameras act as their network device; you can use the existing network and install the new camera. This can make the installation task much easier.
Scalability
IP camera system allows new cameras to be added to the same network. An analog camera system does not let you have multiple networks; you will need new cabling for each new camera.
Better view
IP camera gives you a better view of the field. Which means IP camera can record areas where multiple cameras were required to do the same.
High price, less maintenance
An IP camera is a one-time investment. You can use the existing system to have multiple networks as you go on an increasing number of cameras also can easily find any specific footage you need easily.
The following factors must be considered when a purchase is being made:
Types
We have already mentioned the types of IP cameras above, which would help you choose the camera you wish to buy.
If you need IP cameras in an office, Centralised IP cameras are recommended.
Do you want to monitor the outdoor surroundings of your home while you are away, you may just try the Day and Night IP cameras.
For using only a one or a couple of IP cameras Decentralized cameras may be used.
Fixed cameras hold HD graphics and can do detailed surveillance on one object.
You can go for PTZ IP cameras if you want to do automatic surveillance of the surroundings.
Resolution
Resolution plays a vital part while video recording. IP cameras normally suit VGA graphics but now Megapixel IP cameras are also becoming mainstream. VGA based video produce square pixels which match the computer pixels. Megapixel IP cameras have finer detailing extending to HD graphics.
Infrared
LEDs or Light Emitting Diodes are present in IP cameras which provide night vision. These LEDs produce infrared light at night or in the dark. The infrared vision is necessary if you want 24 hours of surveillance. Infrared light produces black and white videos which come in handy.
Motion Sensing and Alerting
The flexibility for an IP camera is necessary if a wide range surveillance is required. Most IP cameras now can rotate 360º and have independent vision.
Traffic can be monitored by these cameras as they have inbuilt and accurate motion sensing. Zooming along with motion sensing is also provided. An alerting system is also present which sends SMS/emails if any suspicious ‘caught in the act’ is recorded.
Power
Well, the obvious question that arises, what is the power source for the cameras to function. Few cameras use batteries whereas few needs to be plugged into a main source of electricity.
But above all, there is a power-over-ethernet, which allows transmitting power to the cameras simultaneously using the internet connection through the ethernet.
Storage
After the recording has been done where does the footage go? That’s why there are multiple options present for storing.
Personal Computers(PC) or Laptops can be a reliable and a huge source to store recording footage. Multiple connections with IP cameras can be made and it can act as a central server operator.
SD Cards can be used in case the data stored is transported. SD cards are not so reliable as they might get stolen.
Cloud storage is the most reliable source for storing the video footage. Each camera being linked to a cloud account helps in operating the cameras or viewing live footage from any multimedia device.
Accessories
At the end, there come few points for performance enhancement of IP cameras.
Remote control setup – You can use your Moblie or Tablet to operate the IP camera anytime, provided there is a Wifi connection available to both of the devices.
Speaker – It enables a two-way audio interaction. It is helpful if any message is to be delivered to a mass of people.
CCTV Camera Buying Tips
Area of Coverage
Always take note of the pan and tilt or in simplest terms the horizontal and vertical maximum coverages of the CCTV camera you are going for. Most CCTV cameras have the same pan or horizontal rotation capabilities and vary only on their tilt or vertical rotation (90, 110 or 120 degrees).
Type of Recording
CCTV Cameras can work 24/7 as long as it is plugged in a power supply and can record simultaneously on the capacity of your SD Card or any memory storage attached to it. As it overwrites the old files once the memory storage is full, we highly recommend you make it a habit to save old files on other external devices to maximize documentation.
You can also take advantage of the alarm recording, but not all CCTV cameras have this so check on the product features first if they have this. This can save a lot on your memory storage as this only starts recording once motion is detected.
Lighting
To maximize your CCTV camera check on the product capabilities on every lighting condition in the area you will be covering. Good thing on all the featured best CCTV cameras indicated above, they all have Night Vision, just kindly note if their distance coverage fits your requirement.
Features
If you are aiming for the best value for your money, note first the features you will truly need in your CCTV camera. Some go for features they are not fully utilizing hence we truly recommend to not only go over your User Manual but also check on the customer reviews (some links indicated above) for your reference. Features on the coverage, connectivity and image quality are always key features to look for.
