How to choose a outside cctv camera for home security？

cctv outdoor cameras factors:

Since outdoor surveillance usually has a wide monitoring range, high night vision requirements, and has to face more complex external conditions, it needs to be more detailed when choosing. Here are a few factors that need to be focused on:

1、lens focal length

How long is the IR range ? This is a problem we often encounter when choosing a security camera especially outdoor cctv camera monitoring, which often has a wide range and long distance, so it needs to be given priority when choosing.

 

The effective monitoring distance of a surveillance camera is mainly determined by the lens focal length and illumination angle. There are complex calculation formulas, and different manufacturers will obtain slightly different data due to different lens apertures and algorithms. In fact, we ordinary home users No need to know too much.

 

We only need to know : bigger lens focus length, longer we can see, smaller view angle; while smaller focus length ,shorter we can see ,wide view angle

 

What is more ,some cameras is varifocal lens ,you can add just it depends on different view angle ,which is much more flexible .

2、Waterproof and Dustproof

Outdoor monitoring inevitably has to face various extreme weather and environments, so waterproofing and dustproofing are also our priority.

 

IP（Ingress Protection）The protection level is composed of two numbers, such as IP55, IP68, etc.

 

The first number indicates the level of dust-proofing and preventing the intrusion of foreign objects by the electrical appliance. To put it simply, it is the ability to prevent dust from entering.

 

The second number indicates the degree of sealing of the electrical appliance against moisture and water immersion. This is also the number we are most concerned about. The larger the number, the higher the protection level and the better the waterproof capability.

 

For outdoor residential cctv cameras, it must at least meet IP66 or above standards, which means it can completely prevent dust intrusion and withstand the impact of continuous high-pressure water columns. This can ensure they are not afraid of wind and rain.

3、Night vision

Outdoor surveillance usually also has high requirements for night vision. Most of the current mainstream surveillance cameras on the market support infrared night vision. On top of this, there are three types of starlight night vision, full-color night vision, and black light night vision.

4、Storage way

Currently included: memory card storage like SD card , video recording , cloud storage

 

 

If there is only one stand alone cctv camera and the requirements for the video storage period are not high, it is recommended to choose memory card storage, which is currently the most cost-effective storage method.

 

On the contrary, if the video storage period is longer, or if there are multiple surveillance cameras that need to be stored at the same time, it is recommended to choose a hard disk video recorder for storage.

 

5. Power supply mode

Currently, there are four kinds surveillance cameras: power supply professional cctv camera, network security camera , battery operated cctv camera, solar powered cctv camera

 

surveillance camera cctv network mode:RJ45,wifi, sim card

 

But for outdoor camera monitoring, we need to consider power supply and network together

For example:

1. In situations where it is not far from the room and easy to power up, such as on balconies, gates, indoor courtyards, around villas, etc., it is recommended to choose a battery charged camera and wireless night vision outdoor cctv security camera

 

This method saves the trouble of network wiring. When the WIFI signal is unstable, the WIFI signal can be enhanced through a WIFI signal amplifier, which is simpler and more practical in comparison.

2. If there is some distance from the room and the Wifi signal cannot be covered or the signal is unstable, such as outdoor parking spaces, home gardens, vegetable fields, orchards, etc., you can choose best poe cctv camera

3. For some situations where the monitoring range is very wide and it is inconvenient to pull power, such as large farms, fish ponds, orchards, etc., you can choose solar battery power cctv camera outdoor flow card

 

However, it should be noted that the solar + battery power supply method is affected by external factors such as environment and weather. The current technology is not so mature and it is difficult to support continuous and uninterrupted monitoring. The setting of the monitoring strategy needs to be considered during use, and this The cost of this method is relatively high.

Generally speaking, the network and power supply methods for outdoor monitoring need to be reasonably matched according to the existing conditions. For some special environments, it is also necessary to consider poles or choose waterproof and anti-corrosion materials.

 

6. Intelligent functions

For outdoor monitoring, in addition to the basic parameters and functions, you can also focus on the following four intelligent functions:

 

1. Automatic cruise: Outdoor monitoring generally requires a relatively large range of attention. The automatic cruise function allows the camera to automatically cruise through a certain sequence and cycle time interval, thereby achieving multi-point and large-scale monitoring. It is especially suitable for areas such as orchards, Scenes like farms and fish ponds.

2. Motion detection: Accurately determine whether someone is moving in the surveillance screen, and intelligently identify invalid and false alarms, making the alarm function more practical and able to be pushed to the bound mobile phone in a timely manner.

3. Sound and light warning: When someone illegally breaks into a dangerous area, the camera detects the intrusion and can link the sound and light alarm to effectively deter illegal behavior.

 

4. Two-way voice intercom: When an abnormal situation occurs, the local two-way voice intercom function can be used to take quick and effective response measures to various emergencies to avoid losses.

 

These smart functions have greatly improved the practicality of surveillance cameras, and we can also consider them based on actual needs when choosing.
