Important Security Camera Features
Below are some of the important features to keep in mind when comparing home security cameras.
Cameras with movement discovery can send you notices when the camera watches movement inside its field of view. These notices can caution you to suspicious action so you can screen the circumstance.
Field of View
Field of view refers to how wide an angle a camera can record. This is important because it will affect how many cameras you’ll need and where you should place them.
The sound component can allude to your camera accepting sound through an amplifier, emanating sound by means of a speaker, or both. Cameras with both can twofold as radios.
A camera with Wi-Fi can speak with your home system remotely, which can be extremely helpful for establishment, and is additionally less defenseless to being impaired in light of the fact that it doesn’t have wires that could be cut.
The separation from which your camera can record pictures in low-to no-light circumstances can greatly affect its adequacy on the grounds that frequently criminal movement can occur during the evening.
A camera that can skillet as well as tilt might have the capacity to record a bigger territory than a static camera and subsequently diminish the aggregate number of cameras expected to watch a specific zone.
Types of CCTV camera
The use of CCTV has become extremely popular these days with many buildings and homes. There are several types of best CCTV camera in India that are available in the market. The very basic kind of best CCTV camera system is mentioned below.
Dome cameras are used for indoor security purpose and are named after their shape. These types of cameras are mostly used in retail spaces and are installed on the ceiling of the room. In addition, these types of cameras are vandal proof and are designed with infrared illuminators. So go through the blog completely and select the best CCTV camera in India.
Bullet cameras look like an oversized ammo cartridge and have a tapered like design.

Below, we have listed down several factors that play a key role in selecting the right one. Make sure to read them very carefully to understand the terms and their importance.
1. Surveillance Technologies
Basically, there are two surveillance technologies – analog and IP (digital). Each of these have their own set of advantages and disadvantages which we have mentioned them in detail…
Analog: Traditional analog security cameras capture an analog video signal. This signal will be transferred to DVR (digital video recorder) through a coax cable. The DVR will convert the analog to digital, compresses it and stores in hard drives which can be retrieved later. Features like scheduling, zooming and motion detection are available in the DVR. Monitors can be plugged to the DVR for viewing the output.
- They are usually much affordable and more than enough for remote monitoring.
- They come in different varieties from mini covert to large PTZ models. It might a bit easier to find the camera of your style.
- Mix and match of cameras and brands is easier with analog versions. If you have an existing camera then it will be much easier to incorporate into your surveillance system.
IP (Digital): The main difference between the analog and IP cameras is the quality of the video. High resolution and quality video are the two major benefits of an IP security camera. A high quality video ensures a better facial recognition, ability to zoom distances of 100+ feet and license recognition. Actually, the resolution is 2 – 3 times higher than a normal analog camera.
NVR (network video recorder) functions same as DVR in the analog version cameras. NVR will capture signal form each camera, compresses and stores it. The built-in software of NVR will also has features like intelligent search, zoom and others. NVR will combine video signals from all the cameras and broadcasts it over the LAN and internet for both remote and local viewing.
- IP surveillance systems are best for wireless reception. As they have encryption built-into them, they are much more secure than analog systems. Interference is also not an issue with IP systems.
- As IP based cameras act as their own network system, you can use existing wiring network to connect them within your home.
- They are best suited for remote surveillance requirements.
2. Types of Cameras
CCTV cameras are available in different shapes and sizes. You can use one among them based on your unique requirements. Following are the basic types of cameras and their uses…
Bullet Camera: They have a cylindrical shape which and often helpful in areas where discretion is essential. But this doesn’t mean you have to permanently install it in a protective dome. They are best suited for shops, offices and service areas if there is a need to monitor the staff.
Dome Camera: Dome CCTV camera is perfect for surveillance and it also protects the camera from casual vandalism. As it is impossible to find out where the camera is placed, it often provides a good degree of security.
IR Day/Night Camera: These cameras provides 24 hours of security regardless of day, night and lighting conditions. During the day, it provides a colored image and during the nights, it shifts to black and white for infrared viewing.
PTZ Camera: PTZ states Pan-Tilt-Zoom. These cameras are great for large range of motion surveillance system. With powerful onboard motors, these PTZ cameras are flexible enough for any scenario or setting. Though most of the cameras have static positioning, a PTZ camera can be moved in order to track objects, get best view, zoom in/out and in some cases all these things can be done at the same time.
One of the main advantages of CCTV cameras is their ability to respond to triggers and alarms. Normal cameras usually just provide the insight of the alert. But a PTZ camera immediately begins tracking the issue when someone passes through a no-go zone. So, based up on your surveillance requirements, you can choose any type of CCTV camera easily.
In this section, we will look into several specifications that are important to check the performance of the CCTV camera.
Appropriate Lens: Everything we see in the video comes right from the lens which gathers the light for the sensor. Through lens, you can determine or calculates the distance at which the face of person can be recognized. In most of the cases, a better lens is required for great input and output.
Apart from that, buyers should make sure that the camera has a zoom lens. There are two different types of zooms – optical and digital. Digital zoom cannot provided any more information than the original one. Whereas optical zoom will provide a detailed look and new information than the original because it will change as the light reaches the sensor.
Sensor: All digital sensors are not equal. There are two main things you have to consider while looking at the specifications of CCTV camera – sensor type and sensor size.
Sensor Type: Most of the CCTV sensors are either CMOS or CCD. Low priced and tiny cameras usually have CMOS technology which generate poor video quality and very poor light sensitivity. But the CCD sensors produce a better video quality. CMOS require less power and are less expensive than CCD however, they are less sensitive and do not produce a clear image. This can be problematic especially if you have to identify any object or person. CMOS based cameras need more signal processing than normal in order to produce a clear picture. Superior quality CCTV cameras use only CCD technology.
Sensor Size: A large sensor can process more light and produce high quality image. So, the more, the better. Mostly, CCTV cameras come in 2 sizes: 1/3 inch (4.8 mm by 3.6 mm) and 1/4 inch (3.2 mm by 2.4 mm) which means that they have twice surface areas than smaller ones. A bigger sensor gathers more light which provides more data to DSP for working. This is very helpful in less capable processors that come in budget friendly CCTV cameras.
4. Right Output Resolution
Analog and IP CCTV cameras have different resolution specifications. In analog cameras, resolution is counted as TVL or number of TV lines. Usually, analog cameras have a range of up to 700TVL maximum. Most of the analog cameras available in market have between 380 – 540 TVL. At least 420 TVL is recommended by many experts. As a thumb rule, you have to remember that the larger the size is, the higher quality of image you will receive.
When it comes to IP cameras, the resolution is counted in pixels. A minimum 2 mega pixel is recommended by experts. 3 mega pixels is the standard one. But a 4 mega pixel are now becoming main stream in surveillance security systems.
High resolution is very nice to have however the output mostly depends on the input. So, if the lens and sensor don’t match with output generated by DSP then high resolution is a total waste. So, it is very important to calculate the enough resolution so that your camera can produce clear picture.
5. Indoor/Outdoor Cameras
Based on your security requirements, it is better to choose an indoor or outdoor camera. Many outdoor cameras are efficient to work indoors as well. However, indoor cameras should not be installed outdoors. Because cameras installed outdoors undergo risk factors like rain, dust and other weather conditions. So, indoor cameras cannot or not manufactured to withhold such incidents.
6. Do you need Wireless CCTV Camera?
Actually, wireless aren’t completely wire-less. The main issue of it is the power supply. If the wireless camera is working on a lithium battery then it should not after a certain period of time due to lack of juice. That is why most of the wireless cameras are regulated into picture-taking tools which means that it will take a snap shot whenever an undesignated event occurs (something crossing a line or motion detection). Most of the motion detection cameras are wireless.
So, the cables used in wireless cameras are for power supply. They are defined as wireless because they don’t use Ethernet cables to connect with a video recorder. Instead of that, they directly send the data through air. If you don’t like so many cables running all over the place then you can simply choose wireless camera system to simply cut down a large system complexity.
7. Size of the Area You have to Secure
If you want to pin down right camera for you then first consider the distance and size you want to cover. The wide range of outdoor cameras are quite versatile so they can easily cover a wide range, area and depth of an object. When it comes to covering large areas, we recommend taking a smaller lens. A 3.6mm lens can cover at 30 foot distance, 29 foot horizontal. A 6.6mm lens will provide 18 foot horizontal view. A large lens is more precise, focused and detailed in capturing. However, its focus will become narrow and less in a horizontal and wide perspective.
8. Want the cameras to be hidden?
In some cases, users want their cameras to be hidden. This can be due to avoid tackiness, put customers at ease or if surveillance has to be a secret. Some manufacturers provide this option by installing them in clocks or smoke detectors. Alternative options of hiding a regular camera are – putting in a book shelve, hide it in a plant or in a box of tissues.
9. Do you want a powerful night vision?
Most of the cameras have day/night functionality up to some extent. When the intelligent sensors observe a change in the lighting, night vision feature will be activated. Regardless of the darkness, powerful LED’s will help to secure an area of 100 or more feet. If you want to see a specific object or area then it has to be in the middle of camera’s night vision range or else the camera may choose wrong objects to light up. Advanced night vision cameras are more capable of handling difficult and dark situations than normal cameras.
10. Black Vs Colored
Most of the users prefer color cameras however black and white cameras a bit cheaper. If you are placing CCTV cameras in areas where light conditions are low then it is recommended to purchase a black and white one. If the light conditions are good inside then colored ones are best. For built-in night vision, many color cameras use IR cut-filter.
11. Light Sensitivity
LUX is standard specification of camera’s light sensitivity. It defines how the good the camera works in poor light conditions. For example, if the candle is at distance of 1 foot then the illumination of candle on the object is referred as 10 Lux.
