Warehouse Security System: Beams, Alarms, Hooters and Access Control
Short answer: a typical single-shed warehouse or godown with a boundary wall can be covered by an intrusion alarm with infrared beams, shutter and door sensors, motion sensors and an outdoor siren for about ₹19,100. Add a 1 km hooter, an RFID lock on the office door, a fingerprint attendance machine, a fingerprint padlock for the side gate and two fire extinguishers, and the full setup comes to about ₹43,500. All prices below are our live website prices, include GST, and delivery across India is free.
A warehouse is different from a shop. It is large, often empty at night, sits on a plot with a boundary wall, and has staff and trucks moving in and out all day. So security has to work at three levels: the boundary, the building, and who is allowed inside. This guide plans all three with products we stock.
What does a warehouse need, and why?
- Beams on the boundary wall. An active infrared beam sensor is a transmitter and receiver fixed at two ends of a wall. When someone crosses the invisible line, the alarm trips. It warns you while the intruder is still outside the building. The ABT-250 uses 3 beams, and its listing gives up to 150 m between the pair.
- An alarm panel that dials out. The ACJ-400 uses Wi-Fi and GSM, works with door, PIR, smoke, shutter and beam sensors, and calls or messages preset numbers when one trips. At 3 am, that call is what gets someone to the site.
- Shutter and door sensors. The main shutter gets a plunger shutter sensor and the office door a magnetic contact.
- Motion sensors inside. Thieves also come through roof sheets and exhaust openings. PIR sensors cover the open floor.
- A hooter you control. A 1 km hooter is useful for shift start, lunch and closing, and as an emergency warning across a large yard.
- Access control and attendance. Card or PIN entry for the office or stock room, and a fingerprint machine for punch records. This is where most inside losses are stopped.

Cable for the beams, poles or brackets, a SIM card and the electrician are extra. Beam sensors need a power supply at each end, so plan a power point near both corners of each wall run.
How should beams be laid out on a warehouse wall?
- Walk the boundary first. Mark each straight run where someone could climb in. Gates and corners usually need their own pair.
- Keep the line clear. Trees, hanging wires and stacked material break the beam and cause false alarms. Multi-beam sensors like the ABT-250 help, because all beams must be blocked, which filters out birds and falling leaves.
- Mount on the inner side of the wall top, on brackets, so a climber has to cross the beam to get in.
- Do not stretch the rated distance. Rated range is measured in good conditions. Leave headroom for dust and fog.
- Link it to the panel. The CN25 beam is wired to the ACJ-400. For a far wall, the CN35 kit adds a 433 MHz wireless sensor so you do not need to run a cable back to the panel.
For more on beam types and ranges, read our boundary wall beam sensor guide.
Access control and attendance: where losses really happen
Most warehouse losses are not break-ins. They are stock walking out during the day. Two simple steps help. First, keep the office or high-value store behind a card or PIN lock, so only named staff can open it and a lost tag can be removed. The CN152 kit includes the reader, drop bolt lock, K80 supply, exit button and 10 key tags. Second, record attendance on a fingerprint machine so you know who was on site. Note that the S-B251CB is for attendance only, not for opening a door. For face recognition in dusty sites, see the factory attendance guide, and for more door kits, the door access control price guide.
Optional upgrades
- Guard patrol records: the GTS62C guard tour system (₹14,990) comes with 10 RFID checkpoints. The guard touches each checkpoint on his round, and you can check the rounds were done.
- Exit checks: a TECH-03 hand metal detector (₹1,899) at the staff gate.
- Loading bay warning: the TBJ-100 sound and light alarm (₹3,949) combines a 120 dB siren with a red LED flashing light on 220V AC.
- Cameras: the CP Plus CP-V48A 4MP outdoor Wi-Fi camera (₹2,899 each) for the gate and loading bay.

FAQ
What security system is best for a warehouse in India?
Combine infrared beams on the boundary, a GSM and Wi-Fi alarm panel with shutter, door and motion sensors, an outdoor siren, card access on the office door and fingerprint attendance. Our list for a single-shed godown totals ₹43,494.
How much does a warehouse alarm system cost?
The intrusion alarm in this guide (panel, two beam runs, shutter sensor, door sensor, two motion sensors and a solar siren) costs ₹19,096 at our current prices.
Do beam sensors give false alarms?
They can if leaves, birds or stacked material block the line. Triple-beam sensors such as the ABT-250 reduce this because all beams must be broken. Keep the line clear and do not exceed the rated distance.
Can a beam sensor work without wiring back to the alarm panel?
The beam itself still needs power at both ends. The CN35 kit adds an MCT-43 wireless sensor so the alarm signal reaches a 433 MHz wireless panel by radio, without a signal cable.
Will the warehouse alarm call me at night?
Yes. The ACJ-400 uses Wi-Fi and GSM and dials or messages preset numbers when a sensor trips. Keep an active SIM in it.
Can I sound the warehouse hooter from my phone?
Yes. The Combo-CN203 pairs the 1 km SR-1K hooter with a Tuya Wi-Fi switch, so you can switch it from the app.
