Security system integration (monitoring/access/alarm)

Q: Can I buy the equipment only from you and install it by someone else?

Yes. Guangzhou monitoring wholesale price spot, buy equipment to send configuration guidance. But it is recommended that equipment + construction do one, avoid mutual blame when problems; the whole package, then free replacement of equipment failure within the warranty period, free repair of construction problems.

We do integrated construction of monitoring/access/alarm and old system transformation, factories, shops, office buildings, residential areas have done; At the same time do Guangzhou monitoring wholesale (Haikang/Dahua camera, NVR, monitoring panel wholesale price spot), equipment + construction a responsible.

Video surveillance: the gap from "installed" to "well used"

Monitoring is the easiest system to "install is not installed". The difference lies in the details:

sampling design: The backlighting position of the entrance and exit should be equipped with wide dynamic cameras (otherwise the face will be black during the day), the channel should cover the depth of the gun, the POS terminal should be able to see the angle of the banknote denomination, and the perimeter should be crossed without blind spots. We will produce a point map before construction, and confirm with you "what each camera should shoot clearly".
equipment selection: The standard is now starting at 4 megapixels (1080P zoom paste), full-color night vision (ordinary infrared night vision is only black and white, see the license plate color is difficult), H.265+ code (save half storage). Don't be greedy for cheap to buy a less known and inferior brand-six months after the APP server shutdown, remote can't see is common. We are Haikang/Dahua authorized channels, do Guangzhou monitoring wholesale, selection according to the point demand distribution model rather than according to inventory sales, Panyu monitoring wholesale customer day delivery, PC build debugging one-stop.
storage scheme: NVR hard drive to use monitoring dedicated disk (purple disk/cool eagle, ordinary disk 24 hours write cannot last a year); storage days according to the need: 4 channels 4 million H.265+ about 20G per day, to store 30 days with 1T×2. Important places suggest adding cloud remote backup (to prevent equipment from being stolen).
wiring specification: Network cable with national standard oxygen-free copper (monitoring POE power supply, poor quality line voltage drop, remote camera at night when the power off restart is a classic fault), strong ELV separation, outdoor pipe waterproof.

Access control and alarm: stability and authority management are the core

access control system: Select to see the scene-office glass door with magnetic lock + fingerprint/password one machine; factory passage with three-roller gate/wing gate; community and garage with barrier gate + license plate recognition. We focus on two things: ①outage plan: Fire protection requires automatic door opening (escape) due to power failure, but security also requires power failure locking (anti-chaos entry). Different doors should be configured with normally open/normally closed logic respectively, which is a place where many guerrilla construction teams are confused;②authority management: Immediate cancellation of employee permission on the day of resignation, time-division permission (cleaning can only be entered during working hours), temporary authorization of visitors. With equipment that supports cloud management, mobile phones can operate without running the server room.

burglar alarm: Store/warehouse/financial room scene. Infrared curtain + door magnet + glass broken detector partition defense, linkage sound and light alarm + push mobile phone. False alarm rate is the lifeline of the alarm system-pet trigger, air conditioning airflow trigger, direct sunlight trigger false alarm will make users directly abandon the system, sensitivity debugging and location selection during installation are manual work. Alarm system suggests linkage monitoring (alarm trigger automatically pops up corresponding screen video), evidence chain is complete when an accident occurs.

Old system transformation: do not overthrow all over again

A lot of customers old CCTV system (analog era installed) picture paste, hard drive broken record, mobile phone cannot see, want to change and afraid of spending more. Actual transformation than you think of the province:

Line reuse existing gear assessment: The old analog system takes coaxial cable. Two routes: ① replace it with HD camera that supports coaxial transmission (TVI/CVI standard, 4 million pixels take the old line, only replace the equipment at both ends, save wiring costs);② replace the IP camera directly in the area where the network cable is in place. We evaluate it point by point, and we will never remove all the existing gear.
Video Recorder (NVR/DVR) must be replacedOld DVR does not support new camera and network functions, change NVR + CCTV drive, mobile phone remote, intelligent playback these modern functions have.
escalating: The budget is limited and can be phased: change the key points such as the gate/cashier/channel first, and the corner points for the next period. The plan will give you priority.
maintenance single connection: The system that is not installed by us is also repaired. The camera is disconnected, the video recorder is not detected the hard drive, the PTZ is out of control, and the access control is out of order--on-site service starts at RMB 150. If it is not repaired, it will not be accepted.

⚠️ The legal red line of installation monitoring:Cameras must not be aimed at other people's residential doors and windows, bathroom changing rooms are absolutely prohibited, staff dormitory installation needs publicity and consent, monitoring data storage period and access rights must have a system. Store installation monitoring remember to paste "You have entered the monitoring area" prompt. These are not formalism-there are cases of infringement compensation because of the wrong location of the monitoring. We will actively help you avoid these pits during construction.

Hardware warehouse 32-way monitoring transformation, reuse existing gear 70% line saved half of the budget

In April 2026, the old simulation monitoring of a hardware warehouse in Hualong (16 roads, installed for 8 years) The picture is blurred to distinguish the figure, the hard drive has long been broken equal to no video, the boss is determined to transform. The original plan is to completely dismantle and reinstall the IP system, the quote is more than 40,000. After our on-site investigation, we changed the plan: the warehouse area is 8 meters high and the cable is difficult. The 11 coaxial cables in 16 roads are in good condition. Change the TVI HD camera to reuse the existing gear line; the 5 roads with network cable in the office building area are directly connected to the IP camera; 32-way NVR (reserved expansion)+2 4T monitoring panels. The actual cost of RMB 23,000, saving nearly half, the construction period from two weeks to five days. After the transformation, full-color night vision, warehouse access faces and forklift license plates are clear. The boss added perimeter alarm linkage the next month.

Standardized monitoring + cloud management of 8 stores in chain milk tea shops, unified inspection of mobile phones at headquarters

In June 2026, a local milk tea chain (8 stores) had to install monitoring in new stores, and the old stores had a variety of equipment that could not be managed uniformly. We made a standardized plan: Uniform equipment model (4 million full color + POE), 4 - 6 roads per store (POS terminal aimed at cash box, operation area, door, warehouse), unified access to cloud management platform — headquarters operation manager mobile phone on an APP tour 8 stores, POS terminal dispute directly adjust cloud video (30 days of local NVR storage + permanent cloud storage of key clips). 8 stores invested a total of RMB 36,000 (including cloud storage annual fee). After the third month of installation, it was used: a store customer complained about drinking foreign objects and claimed compensation. After adjusting the video, it was clear that the customer opened the lid himself and invested, avoiding a false compensation and bad evaluation storm.

FAQ

About security system integration (monitoring/access control/alarm), we are often asked

What are the recommendations for home surveillance?

Three key points: ① Choose big brands (fluorite/millet/Huawei, etc.), change bricks after stopping the APP and reveal privacy;② use indoor PTZ machine at the door/living room, waterproof gun machine in the yard;③ must open the "privacy shielding" function to demarcate the area, do not face the neighbor's doors and windows. Home is generally 1-3 roads, we buy our own equipment to find us to install, installation and debugging RMB 200/road.

How long does the surveillance video last?

According to the number of ways, resolution, hard drive capacity calculation: 4 ways 4 million H.265+ about 20G per day, 1T hard drive storage for about 50 days;16 ways to start 4T. To save longer add hard drive or reduce the bit rate. Important places recommend 30 days to start + key fragments cloud backup.

What if I can't see the surveillance phone I already installed?

Three possibilities: ① equipment miscellaneous brand server shutdown (change equipment to cure);② network configuration problems (router port mapping/manufacturer cloud service is not open, we can repair);③ account password lost (find manufacturer complaint). On-site service from RMB 150, diagnosis first and then quote.

Do you accept large projects in factories/parks?

We have done factory perimeter (wall infrared radiation + electronic fence linkage monitoring), park access card (canteen/dormitory/workshop authority classification), temporary site monitoring (4G wireless rapid deployment). Large projects go through the complete process of "survey → proposal → quote → construction → acceptance → maintenance", and can provide qualification documents and past case references.

Can I buy the equipment only from you and install it by someone else?

Yes. We do wholesale Guangzhou surveillance, camera/NVR/monitoring disk are wholesale price in stock, buy equipment to send configuration guidance (point advice, storage calculation, APP settings). Installation is also OK, but it is recommended that equipment + construction do--the biggest risk of doing it separately is to blame each other when there is a problem. If we package the whole package, then the equipment failure is free to replace during the warranty period, and the construction problem is free to repair.
