Thanks to the development of home Wi-Fi systems and the universal introduction of smartphones, you can install the best IP security camera in your home in just a couple of clicks. After launch, it will remotely notify of suspicious activity near the house using a smartphone, SMS or email. Before users spend their money on the purchase of a device, you need to have a clear plan on how the surveillance system will be arranged at the facility.
IP Camera View
The network IP camera operates using the IPv4 Internet protocol instead of analog electrical signals. For this reason, IP cameras are also called network cameras. Standard industry protocols for them are the Open Network Video Interface Forum (ONVIF) specification and the Real-Time Streaming Protocol (RTSP). Analog cameras require a central device to control and record data such as DVR (Digital Video Recorder). The DVR is called so because it writes to a disc, therefore it is digital, and the cameras themselves may not be “digital”.
The cameras work independently. Most of them have a built-in mini-chip, which allows you to work either in a centralized or decentralized mode, or both, if they have sufficient power. In centralized mode, the internal surveillance cameras are controlled by a network video recorder (NVR) and interact with other IP devices, which is why NVR is necessary.
The cameras connect to it via Ethernet cables or wirelessly via Wi-Fi. In decentralized mode, they are not connected to the DVR that controls them. Each mini IP camera is independent in the local area network LAN, and works simultaneously in both modes - in the NVR system and in the local area network.
Comparison of Internet cameras and DVR systems
If the user is new to security cameras, the NVR system will simplify installation and setup. If it has analog cameras or a coaxial cable, then a DVR camera system can be a convenient solution.
Experts will recommend NVR systems to anyone who wants to have a higher level of security at home or in business.
Advantages over analog CCTV:
- Allows you to receive SMS, email and push notifications on your mobile phone.
- They have advanced routing algorithms that reduce false data and detect violations.
- Digital video with smart warning markers makes browsing easy.
- An important element of the home network, as the Wi-Fi IP camera works with the subsystems: opening doors and turning on lights.
- Greater installation flexibility as they can operate over wired and wireless networks.
Camera classification by form factor
The camera form factor describes the type: from bullet cameras to domes and small hidden devices. Different shapes are suitable for different places, including indoors or outdoors, which makes it possible to choose a camera that meets the requirements of observation. Varieties in the form factor are as follows:
- Bullet, the most common types of video surveillance. The most budget type, is not very resistant to vandalism, but at the same time offers flexibility in mounting positions and settings.
- Domes are preferred in commercial environments. They are highly resistant to vandalism and weathering, all due to their mounting position. They are more complicated, and the setting after this can also be very limited.
- Mini-dome or revolving cameras are anti-vandal devices. Nowadays, more and more companies are launching these types of models.
- Cubic are installed in the corner of the premises. They usually come with built-in communication devices, so they are also used as intercoms.
- Cameras with focal flexibility. The amount of zoom available depends on the different focal lengths and also the FoV overview. For long lanes, this 6mm focal length camera is simply gorgeous. For the backyard you will need a wide FoV 2.8 mm. Of course, the disadvantage of such a lens is that the image will be distorted near the edges.
- Fixed mini IP cameras use a lens set at one focal length, which makes camera selection even more critical.
- Hand-held devices with variable focusing lenses, such as from 3 mm to 10 mm, which can be changed manually.
- Pan-Tilt-Zoom (PTZ) are motorized in all axes of movement.
Choosing a Model by Aperture Type
The best IP camera needs to be selected taking into account the lens. The lens aperture determines how much light is allowed to apply to the sensor. The smaller the aperture, the less light. The classification depending on the type of aperture is as follows:
- Fixed aperture.
- Auto-Iris motorized variable aperture.
- Precise Aperture (P-Iris).
For applications where a qualitative increase is required, for example, when recognizing license plates, an aperture with automatic control is a priority.
Proper selection of a security camera
Before choosing a network IP camera, you need to clearly plan where they will be installed. The necessary type will depend on this. Search Features - Below:
- Support ONVIF and RTSP, which will ensure compatibility with NVR.
- Power-over-Ethernet support replaces the use of two cables (power and network) with one when power is transmitted over the same data wire. This is very convenient as long Ethernet routes can be used.
- Weather protection to check that outdoor devices are compatible with IP66. It is recommended to additionally treat a layer of sealant around the camera to enhance protection.
- Recommended resolution of at least 2 megapixels - 3 is standard, but 4 megapixels is the main choice.
- Type of lighting. Most Wi-Fi IP cameras have infrared lighting. Devices with IR will gradually be decommissioned, because the created IR has the effect of a flashlight, therefore it is applicable only for small spaces. In addition, this light attracts flies and spiders, and this blocks the view or triggers the motion sensor, so EXIR LEDs are more powerful and more durable.
- The need for wireless communication must be clarified before choosing an IP camera. Experts do not recommend using Wi-Fi for cameras in terms of reliability. In this case, network networks are preferred because they are more reliable and faster.
- The size of the data store. These are usually SD card slots supporting up to 128 GB of capacity. Many people like to use cloud storage. Some cloud cameras, such as Arlo Q Plus, now have local storage if an internet connection is not available.
The best cameras are those whose cloud functions are strictly optional and allow you to access their videos using third-party applications.
Wireless Security Devices
IP cameras with WiFi for the home are divided into 2 types: rechargeable or solar panels and traditional wireless surveillance cameras. The biggest difference between the two is the power source.
Rechargeable (solar) powered by batteries or a solar panel, which makes them devices with zero wire. This type of security camera is portable and the easiest to install home intelligent security systems. Traditionally, the best IP camera should be connected to a power source. Communication between her and the home router is through a wireless signal. Like wired, wireless security systems have their strengths and weaknesses. The benefits of an IP camera with WiFi for home are as follows:
- Simple and quick installation.
- More flexible.
- More portable.
Disadvantages of Wi-Fi Security Camera:
- Possible Wi-Fi interference from neighboring devices.
- Hacking risks.
- Higher price.
NVR NVR
Most cameras function without NVR. Some have built-in storage for SD cards, which is used for instant photos and video clips. The many benefits are that the NVR records video from cameras in 24/7 continuous recording. In addition, it is possible to backup video materials if the camera is damaged / destroyed / stolen, and you can also view it from one interface.
If the user has 4 devices and does not want to watch each in turn, he can simultaneously play video streams from several objects, which provides quick reviews manually. At the same time, if an amateur has 1 or 2 cameras that have built-in storage, then a DVR is not needed. With a lot of it is recommended to get a network video recorder. If coordinated operation of the equipment is needed, it is recommended to choose a camera and NVR from the same factory.
Video Resolution Limit
The resolution of IP cameras is very important. In 2018, 720p resolution is simply unacceptable. If the attacker's face is not directly against the camera, 720p simply cannot capture an exact photo to identify a person, especially in the dark. The minimum recommendation is 1080p Full HD (or 2 megapixels). The field of view or horizontal viewing angle depends on the focal length of the camera lens.
The wider the horizontal viewing angle, the more flexible the camera will be placed in a difficult place, for example, in a wide living room. Some manufacturers indicate in the passport data of devices a diagonal angle, which can be misleading, since it will always be higher than the horizontal - for example, like TV screens.
Night vision function
InfraRed Night Vision is critical for quality night shots. A true IR filter allows you to create true color images during the day and high-quality images at night. EXIR LEDs are brighter and have a longer life than conventional LEDs used in low-cost cameras. The best backlit IP camera is one that doesn't need outside help to get the job done. All she needs is electricity.
It is better to use a UPS to provide backup power in case the attackers turned it off, RTSP, which allows access to the video stream from a third-party application, such as tinyCam Monitor Pro or IP Cam Viewer. ONVIF support is ideal, so you can connect the camera to an NVR, such as an Amcrest NVR, which can support any ONVIF-compatible camera.
Full duplex systems
Most cameras that have a built-in microphone and speaker are not full duplex - they are half duplex. This means that you can not conduct a conversation in a natural way, you have to accept the style of the walkie-talkie for talking on camera. Therefore, to create a modern security system, full-duplex capabilities are needed, as well as software functions - email alerts about motion, sound, noise reduction and push notifications for smartphone applications and a motion detection method.
Although software-based change detection is the most common method, a PIR motion sensor is preferred to remove false signals. This will require a reliable power source. In this case, the wired Ethernet port is preferable to wireless connections for maximum reliability.
